Thank you so much for this video. I replaced the intake cam sensor. That wasn’t it. I had a code for missing cylinders and an oil leak from the valve cover gasket. So I set out to change the valve cover gasket, VVT sensor, plugs and coil packs. Got it all back together and same issue, just like yours. Rough idle and surging idle and would sometimes die at a stop. This came on all of a sudden. Then I saw your video of cleaning the two VANOS cylinders. So I did. The car runs great. Smooth idle with good acceleration and no lag. Thank you for this video it was awesome.
Had the P0012 and the P0015 faults after I changed the valve cover gasket. Watched this video, had the vanos cables swapped. Swapped 'em back and no issues! Thanks man! 07 335 N54 here.
I used and watched this video like 6 or 7 times and I cleaned both vanos solenoids in my 2009 bmw 328i. I did finally get it done. It took me a lot more time than you to do it because of my lack of proper tools and my experience working on vehicles. I did it though and just plugged them back in. Fingers 🤞 that it fixed my issue. About to start her up now. 😂
If you have P0012, P0015, or P1554 (all related to camshaft/vanos), change your oil and filter first before trying anything else. Make sure your oil level is correct. Low/bad oil can cause these to trip very easily!
Huge thank-you 2006 BMW X3 m same symptoms cleaned them out,idle is perfect and it feels like it has more power than brand new then when I got it. It even starts up super quick no problems
2007 523i. A quick cleanup on both valves and problem solved, engine idles now smoothly, much better that before and no more fault code, for now anyways. Thanks for the video
Hey Nathan bought a 07 x3 with n52 that was doing same thing. Slow to come on the throttle and rough idle at stop light. Saw this vid and figured it's an easy job for me and boom. Drives like a different car now. Now have a responsive throttle and smooth idle. If prob returns, I will replace them. MPG may be better too. Thanks for great vid. - Dave
I had the same codes and on the inside of the oil filter cap the cartridge was missing, that goes inside of the oil filter and I had to buy a new oil filter cap. That fixed my issue.
Legend status achieved . Been a mechanic 7 years and this was the first time i came across this problem. looked up online and came across this vid... Going the the shop shortly to give'er a try ill let u know!
Fantastic tip. I own a E91 325i, after oil and filter change rpm jumped between 1100 and 550 and finally died. I did what you advised and it worked perfectly. Magic! Thank you very much! I’m your new subscriber 👌💨
@@DeoryDiditbeaver. This issue shows how small things can cause a major problem but best solution is prevention: as simple as keeping all the filters clean, hoses and connectors in tact before having to spend big $$$
I have 06 325i with 150k miles and the check engine light on. Code P0012. Intake vannos solenoid. But, took both vanos solenoids out like you said and cleaned them. Boom. Went to get a smog test today and passed. If I could buy you a beer I would. Thanks for the video dude much appreciated!!
i have the same car like you and my car starts and kinda idle idk my dad changed everything already like new sparks plug , new sets of coils , change air filter , oil filter , new oil , new fuze , new starter , new battery but car still the same . should we try doing this ?
Thank you for the video! After watching and doing the work on my car I could tell an obvious difference in the driving performance. I didn’t clear any codes so idk if that is the fix needed to clear my light. It’s saying I still need to change the cam sensor. But thank you!
To my knowledge these cars were turned down when they were manufactured to pass emissions in the states after long long hours of scanning and troubleshooting I decided to replace everything after that still had problems. I took it to a buddy's shop wala I updated software/firmware whatever just updated everything and problem has no returned hope this helps.
Nice vid and fix. Would have been pretty interesting to see the short term and long-term fuel trims before and after on this to possibly rule out a failing or faulty reporting MAF sensor.
Thank you, champ! Same issue, I had a sticky original 325k km vanos, basked it in carb cleaner like you did, the first two starts were naturally "rough", a few gentle revs to get the oil flowing, third start, went mint
2008 N51 328xi. I've been experiencing similar symptoms you described about the slightly rough cold idle and the delayed throttle response. No issues on the highway and no drastic surges in engine speeds during idling. Car sat for two years so I think stuff gummed up inside. I've done multiple oil changes, went through two tanks of new gas and a bottle of Techron. New plugs and Delphi coils. Scanned it with INPA using the Rough Running and Lamda Probe Voltage screen and the values fluctuate a lot but they're within the green. Also the cylinders are different from each other - my understanding is they should be close to each other on a healthy engine. The throttle response has gotten better the more I drive it. I think also resetting the oil life on the transmission and transfer case using ISTA has made a performance improvement. I'm gonna try cleaning the VANOS valves as the fact that the car hasn't been driven in a long time could explain this behavior. Will update once I get it done.
Great, it is so helpful, I did it in the morning and it worked. The only thing not clear to me is what to do with the oil in the main part. Isnt the vanos going to be the same again when we put it back in there? As I could not clean the inside, I am expecting to have same issue?
If you put it on inpa you can see whether the cams are operating properly, while it's running. You should replace those seals and change the oil while you're at it. Makes a world of difference when these things are operating properly.
My issue just turned out to be that little red box with the fuse on the battery. I just changed that fuse box thingy and got back to normal. Hope that helps
hello I have a 2000 BMW 528i e39, the EML light comes on, I fixed the PS valve on top of the trottle, and in the spider it has a diesel valve that is not a trottle. nothing!!! how to fix that code thank you
I did the same on a 05 523i e60. But i took elec wires and test them on the battery.. So immediately i can tell top solenoid was fine and operating normal. You can hear the solenoid ticking. The lower one not good, although it tries to work you can tell its not operating good. So i cleaned it with break cleaner and immediately you can hear working again. So ok, fault codes were gone and the engine ran great.. But, the next morning that lower solenoid were giving me trouble again. After replacing him alone the car is fixed. Cleaning is temporary you have to replace them
I’ve got the same code, haven’t replaced anything but I bench tested the solenoids, they work fine. Cleaned the solenoids up and put them back in, didn’t fix anything. I did an oil change afterwards and it was blackk said the last service was 2020 so would it be good to start with cleaning the solenoids again? I was gonna test the cam sensors too
I don't know if he ran the car earlier and it was warm but when you start a car like this it doesn't just run off of the whole system for the first 30 seconds to 1 min. It uses a program from the computer initially then cuts over the all the sensors and things to make it run more efficiently. So he needs to wait until it changes over to the secondary idle before he sees anything change or not.
Great video. But I have a quick question! On my 011 328i xdrive when replacing the vano do I have to do some type of reprogramming or adjustment. Or its just a plug and play selenoide? Any answers will be well appreciated.
I had a code for the B camshaft bank one I cleaned both vanos solenoids now the car runs worst and idles up and down! Light came on for P052 and misfire codes. Any guess what it could be? The connectors are plugged in the right vanos
Also there is a guy on here from UK that update has worked for him as well. But still check all sensors to make sure they wornt damaged before update and also complete all recalls before doing updates.
Had p0012, i already changed spark plugs, coils, valve cover gasket, cmp sensor, and my 325 had a Recall for Vanos replacement. And still get the p0012 I cleaned vanos solenoid and vanos filter maybe not enough cleaned but any other suggestions? Lost of power and rough idle at star then has a steady idle
What I do about every 30k is clean these solenoids and switch them around. There’s a guy on e90 post who has over 300k on his e90 and swears by this...
i was put into limp mode on my bmw 335xi my belt shredded replaced it and now i got the p0012 code this is my first problem with my car i believe its the solenoid but the mechanic whats to take apart the engine and make sure there isnt belt can i just get the solenoid replaced and oil change to prolong until i get paid will that work?
So I shouldn’t get a new once and replace them? Just clean them and should work? I’m not good at this, but I got the code 12 as well on my x5 2010, I’m not sure how to now if they need to be replaced
My shit cutting off everywhere I think battery is bad when it cuts off I can usually crank it back but today had to get a jump . Imma change these again and the cranksensor understated
I have a bmw e90 and l recently did my service changed oil, oil filter, plugs and air filter but l am still having a problem its consuming a lot of fuels 14L/100 and there's white smoke at the exhaust pipe and l smell unburnt feul also with a rough idle any idea what the problem is.
Is there anything besides the vanos and mass air that i should clean to stop that surging? My 2010 528i only does it when im stopped. Thanks for the knowledge.
Hey, a huge thank you for this video! I have been dealing with the same problem on my 2010 X5, but not any more. You are the only person that seems to be down to earth with an easy cheap fix/troubleshooting (and no b/s talk). I was able to follow your video while doing an oil change. I finished cleaning and reinstalling before the oil finished draining! Thanks man!
I was getting a camshaft intakr code p0010 change both cam position sensors code still shows. Swapped vanos after cleaning two times intake/top 2 exhaust/lower and threw a p0013. so i ordered only one new solenoid after market since i heard they work fine and seems like only one is bad after swapping confirmed. Now the car is throwing p054b than a p0015.
I don't have a check engine light but I do have a surge problem especially sometimes in reverse or forward when starting the car now it's at the stop sign so even if I don't have a check engine light can I still clean this
I have errors p0012 and p0015. I need your hint. I have to change the solenoid and the cam sensor. Or is it just the sensor? waiting for your answer. Thank you!
I change the valve cover gasket on my 2008 e90 but now I have misfire on cylinder 3-4 no spark what so ever! I swapped the ignition coils around but problem continue. Any help in pinchi pointing out the problem?
I have a 2008 X3 3.0SI with the N52 with 107,000 miles on it. Shortly after purchasing it I got those two codes. After searching everyone said it was the vanos solenoids. So I replaced both of those with OEM parts. A week later the codes came back. I bought another vanos solenoid thinking maybe I got 2 bad ones. I replaced just one of them. The codes came back shortly after and it again was both intake and exhaust at the same time. I took a shot in the dark and replaced the vanos check valves, the codes still came back. Then I replaced the camshaft position sensors thinking maybe they were just broken. The codes still came back. When the codes do come back it is usually just after startup and I can feel the engine surge a bit, and then it throws the codes. Curiously every single time it throws the codes it is both intake and exhaust at the same time. I think it might be the vanos actuator motor? To summarize I've replaced: Both vanos solenoids Both camshaft position sensors Both Vanos check valves Either way I want to stop throwing parts at it in hopes it will fix the problem. Any idea. Please I need you help I know you own bmw. Thank you for you time.
Im having the same issues I replaced both solenoids and crankshaft and camshaft sensors still getting p0012 and p0015 codes it's 2008 528i bmw. I will note all this happen after a delayed oil change smh.
Trying getting a firmware update. If that doesn't work, your cam bearing ledges might be worn. That usually means a new head. The firmware update has been working for people though.
Did you clean your vanos filters? There is a video called "non return vanos filters". The guy pulls the filters out, cleans them and it fixes the problem.
@@MrTruthAddict Braxton European came up with worn or damaged crankshaft gears that needed to be replaced also with some fluids changes like trans and coolant but it came up to 2500$

Nathan if you have installed LED bulbs anywhere on BMW, you can use NCS EXPERT to disable cold and warm check on those places so you will not get that annoying warning on dashboard. On my E53 N62 I did that in LMA module. Just read it out and in Notepad you should change: Parking Lights / DRL Cold Check Left : AUSG_04_POL_L_KALT_UEBERW_AKTIV Parking Lights / DRL Cold Check Right : AUSG_05_POL_R_KALT_UEBERW_AKTIV Parking Lights / DRL Warm Check Left : AUSG_04_POL_L_WARM_UEBERW_AKTIV Parking Lights / DRL Warm Check Righ : AUSG_05_POL_R_WARM_UEBERW_AKTIV to NICHT_AKTIV and upload it to module.

Also if this would have not fixed it you might have a crank sensor problem. When I got my car after standing for a while it had rough idle and long starts, apparently the rats ate threw my crank sensor wire near the starter so I fixed the wiring harness and it runes good now
my bmw E90 turns on everything comes on fine but rpms don’t rev past 1000 the tac jumps up and down when it’s sitting, plugged in my scanner and it threw a code for valvetronic motor. car is in limp mode, what could be the problem?
yep that sounds right , if the solenoids were leaving the timing advanced on the next start up the extra advance and the early combustion before tdc would cause the slow cranking and the abrupt stop of crankshaft rotation when the crank tries to turn backwards , that would also triggers dtcs , misfires-backfires, cas sensor sync, , makes you wonder whether manufactures are over complicating things , I know the development of bigger and faster processors in ecu's with more feedback channels to the ecu and this has resulted in more efficient, smoother running engines with more horsepower and torque and at the same time the increase in data feedback to the ecu has not improved the diagnostics ability to pin point faults, the older systems were more straight forward . when a mazda 3/6 throws a cam angle sensor code when mechanical failure of a friction washer cause the crankshaft sprocket to move is due to poorly coded firmware and flaws in the designs of keyless sprockets that were implemented to save production costs , that end up costing the customer money and independent mechanics time and money. with all the telemetry data available at the ecu these days surely the software engineers could create a system with a on board user interface that is not as vague and draws a more complete picture, it looks like the dealership service departments need it. some scan tools work better than others and that probably due to being able to connect with the proper protocol in order to read the data but at the same time they can only work as good as the obd system that they connect to provided that the tool has no errors in reading the data, i have experienced different results using different tools on the same vehicle. I have seem the merc and BMW scan tools that the dealers use, it was software on a laptop and it was pretty elaborate may I ask how much the scan tool was, because i have searched and found the same ones online but I see some priced at $130 and other prices at $400.
@Arnold Rimmer If you have some tuning experience ? Or Have ever set up an aftermarket Ecu and cranked an engine for the initial start with to much ignition advance Normally the fire is lit some crankshaft degrees before tdc and the crank has come over to where the force of the piston pushing down and the crank is past Tdc causing the crankshaft to rotate in the right direction that advance Is for the delay in combustion If you light the fire to early the piston is still on it’s way up and not past rev and the crank hasn’t come over. The piston will push the crank back in the direction it came from. You will notice this as an abrupt licking or even backwards motions when you crank and engine with to much ignition advance The engine doesn’t actually start up and run backwards Hence the term trying to run backwards It’s a term tuners use to say to much ignition advance at cranking
@Arnold Rimmer you obviously have no experience with dyno tuning vehicles and you’re not familiar with the terminology. Don’t be so quick to try and make people look silly Did you even stop and try to think about how what I said can be mechanically possible ? No of course not Coz you thought you had me Buddy I’ve been tuning cars for 15 years Built an r33 gtr skyline that made 630kws at the rear treads and an evo lancer that made 403kws. Never at any stage we’re you going to stump me or did you have me got with your amateurish comment and as it turns out the reverse gear push start is not the only way an engine will TRY to run backwards when cranking Read the words carefully. Don’t be so quick to try and prove. You know everything what direction would you be pushing the car when you use reverse to start it This is one of the stupidest things I have also ever heard and like you said why would anyone do that ? Why would you even try and explain the only way you think it’s possible. Is it because you think that were are all so stupid and only you can figure that out ? But there is no point to what you are trying to say. You want to avoid having that issue with slow cranking or lock up and backwards motion at cranking
@Arnold Rimmer but I am glad you used the words “I can’t see how” instead of “it’s not possible for” the crankshaft to rotate backwards during cranking just encase I had the answer
@Arnold Rimmer I used the aftermarket Ecu and tuning as an example so it’s be easier. To convey and understand the issue can arise with Unmodified vehicles, ignition base timing. is not always locked in one position. Some have the provisions for adjusting the base so you end up with the actual timing matching the timing that the. Ecu map is air temp sensors or. Coolant temp sensors will advance and retard substantial amounts of timing and faulty sensors could cause the described scenario A faulty air temp sensor that is stuck on a resistance that tricks the Ecu into thinking the air temps are -10c will trigger compensation table that can add fuel to the base fuel . Maps and to ignition.base maps I don’t remember what this video was about and I’m sure my comment was relevant otherwise I wouldn’t have made it and I’m sure as hell not going to watch it again because you are not familiar with the terminology and are having trouble accept what it relates to Whether average joe or not it would benefit joe if he actually took the time to learn how it all. Works Whether a race car or production car that you by from a dealership It’s all the same Do You realize that the averages joes family car was also dyno tuned or the configuration. That makes run cams from an exact copy vehicle or engine which spent 1000s of hours on a dyno in order to refine the tune so every possible scenario is covered and the engine doesn’t mis behave In Extreme conditions like cold or hot weather. Altitude changes etc air temperature. Air density and even different fuel octane in some vehicles or e85 content compensation The issue is that you tried to make a fool out of me and you thought you knew what you’re talking about and now you’ve been schooled on the topic and your back peddling Don’t be pissed off at me for having extensive knowledge in the field that I spent 15 years in. For a living. Everyday Be disappointed with yourself for trying to troll someone and making an ass of yourself Instead of them So now you’re just talking about one specific isolated issue are you ? I think you are just talking rubbish You don’t know what you. Are talking about. But you thought you did I don’t understand what you mean Are expert knowledgeable comments not welcome Only average joe comments are permitted We don’t want to over complicate things and actually learn how things actually work You didn’t know how and engine can try to run backwards while cranking I explained it I don’t see and argument saying that my explanation is not actual fact And now you do see how an engine can in fact try to run backwards while cranking (is this correct ) you do now understand ? I explain how it is possible I’m all types or vehicles. And it’s all related to ignition timing So that would include any vehicle with a Piston engine running spark ignition To much advanced Engine try to run Backwards No exceptions
hello from france i have a little rough idle noticeable when car is hot on my z4 3.0si n52b30 replace my ccv but still same looking for which is the culprit as it is rough only when it is hot in the morning there is a little rough idle but not more than when car is hot what could you advise me to check first ? please note beside problem idle my car runs and drive like a dream
My N52 (on a 7 series!) fluctuates once after every start - could it need this cleaning as well? Or is it the DISA? No errors codes or check engine lights. I changed the oil separator and pipes, did not cure it. Engine runs beautifully other than this annoying throttle blip on startup
Yes the N62 has the same issue. It just has four vanos solenoids instead of two. Cleaning them and replacing the rubber seals will fix the problem. Make sure you use good oil and don't let the oil get dirty. It will clog up the oil galleys and you'll have this problem again.
My n52 6mt will burble in w.o.t. under 3500 r.p.m. Sometimes it throws a engine light but service scan reads o.k. Could I let those solenoids soak in carb cleaner overnight?
You would not believe the problems you would have with a week battery . the engine races and never idles down . the fan sometimes don't work on high until you drive it for an hour... And then if you get a battery that is 90 or 80% brand new you still have problems...
hi hathan i have 2010 bmw x3 177000 mile getting cylinder 4 and 6 misfire, changed coil and sparkplug and also clean the vanos selanoid but still getting the misfire and car hagistate at low rpm (Rough idle) any idea what could be wrong also changed valve cover gasket
Nathan thanks for your videos. I bought a E46 M3 for my daily driver. How hard is it to complete a service 2 for my 90k miles? Should I try to check the Vanos myself? I'm good for basic maintenance but not sure if the Vanos is too involved. I just changed my alternator but that seems simple in comparison. Thanks.
Nathan my 335i n54 has had a rough idle recently it will come and go ...but at idle it will idle and then drop down to about 200rpm or so , bring it back up and then trys to stall and catches itself ...can't find any vaccum leaks , injectors were replaced a couple years ago , high pressure pump was replaced under warranty a few years ago. Think maybe the vanos solenoids could be the issue ? I have no engine lights other then one code for an evap pump .
Thank you so much for this video. I replaced the intake cam sensor. That wasn’t it. I had a code for missing cylinders and an oil leak from the valve cover gasket. So I set out to change the valve cover gasket, VVT sensor, plugs and coil packs. Got it all back together and same issue, just like yours. Rough idle and surging idle and would sometimes die at a stop. This came on all of a sudden. Then I saw your video of cleaning the two VANOS cylinders. So I did. The car runs great. Smooth idle with good acceleration and no lag. Thank you for this video it was awesome.

If you have P0012, P0015, or P1554 (all related to camshaft/vanos), change your oil and filter first before trying anything else. Make sure your oil level is correct. Low/bad oil can cause these to trip very easily!

Hey Nathan bought a 07 x3 with n52 that was doing same thing. Slow to come on the throttle and rough idle at stop light. Saw this vid and figured it's an easy job for me and boom. Drives like a different car now. Now have a responsive throttle and smooth idle. If prob returns, I will replace them. MPG may be better too. Thanks for great vid. - Dave
Can't thank you enough for posting these BMW video's...Thanks
Thank you for watching
Your guides are the best. Always informative. Thank you for helping the community save money. Keep up the great work.
Great tip on where the connectors go. 3:18 in the vid. I had them swapped >
I had the same codes and on the inside of the oil filter cap the cartridge was missing, that goes inside of the oil filter and I had to buy a new oil filter cap. That fixed my issue.
Totally helped me fix my car brother thank u so much!! Thousands saved!
Legend status achieved . Been a mechanic 7 years and this was the first time i came across this problem. looked up online and came across this vid... Going the the shop shortly to give'er a try ill let u know!
It's been a year now, and we're still waiting for you to let us know?
@ Come back next year
I’m waiting too ..
Maybe covid got him 🤔
Too bad we coulda rlly used the advice. Check back next year!
still waiting
You hit the nail on the head there, BMW's are not the problem, it's the clowns who do not know how to fix them.
That logic don't make sense. Anyone can say that with just about every car brand and model or with anything else for that matter.
@@orangecounty7144 Because every car has their own little problems.
Fantastic tip. I own a E91 325i, after oil and filter change rpm jumped between 1100 and 550 and finally died. I did what you advised and it worked perfectly. Magic! Thank you very much! I’m your new subscriber 👌💨
What finally died?
@@DeoryDiditbeaver. This issue shows how small things can cause a major problem but best solution is prevention: as simple as keeping all the filters clean, hoses and connectors in tact before having to spend big $$$
I had the same problem and I found out my oil filter cage was missing so i installed a new one and it fixed it
I replaced solenoids, still throwing code.
Finally I changed the oil, problem solved!
It's possible that the valves were getting blocked due to the contaminated oil.
Was the idle rough? I just installed a new pair and it seems to Jolt.
thnxs for that comment worth gold;)
What kind of oil
the idle control valve can cause similar symptoms, it can be taken off n sprayd with carb cleaner n some q tips n place it back in n work like a champ
I have 06 325i with 150k miles and the check engine light on. Code P0012. Intake vannos solenoid. But, took both vanos solenoids out like you said and cleaned them. Boom. Went to get a smog test today and passed. If I could buy you a beer I would. Thanks for the video dude much appreciated!!
i have the same car like you and my car starts and kinda idle idk my dad changed everything already like new sparks plug , new sets of coils , change air filter , oil filter , new oil , new fuze , new starter , new battery but car still the same . should we try doing this ?
@@tonymollyhawj1389 yessss of course.. did it work?
Thank you for the video! After watching and doing the work on my car I could tell an obvious difference in the driving performance. I didn’t clear any codes so idk if that is the fix needed to clear my light. It’s saying I still need to change the cam sensor. But thank you!
To my knowledge these cars were turned down when they were manufactured to pass emissions in the states after long long hours of scanning and troubleshooting I decided to replace everything after that still had problems. I took it to a buddy's shop wala I updated software/firmware whatever just updated everything and problem has no returned hope this helps.
How did he updated it??
Nice vid and fix. Would have been pretty interesting to see the short term and long-term fuel trims before and after on this to possibly rule out a failing or faulty reporting MAF sensor.
Thank you, champ!
Same issue, I had a sticky original 325k km vanos, basked it in carb cleaner like you did, the first two starts were naturally "rough", a few gentle revs to get the oil flowing, third start, went mint
"Try changing the solenoids"
~Tom Cruise, War of the World~
"Solenoid". There's only one on the starter. That is what he was talking about in the movie.
@@DaytonCarCare lol
DaytonCarCare there’s a solenoid for intake, and one for exhaust
In any repair and diagnosis, one must check the engune oil leve, the battery voltage and the charging system operation within specification
Do those o-rings have to be in the groove? Can you slide the o-ring up against the plastic ring?
2008 N51 328xi. I've been experiencing similar symptoms you described about the slightly rough cold idle and the delayed throttle response. No issues on the highway and no drastic surges in engine speeds during idling. Car sat for two years so I think stuff gummed up inside. I've done multiple oil changes, went through two tanks of new gas and a bottle of Techron. New plugs and Delphi coils.
Scanned it with INPA using the Rough Running and Lamda Probe Voltage screen and the values fluctuate a lot but they're within the green. Also the cylinders are different from each other - my understanding is they should be close to each other on a healthy engine. The throttle response has gotten better the more I drive it. I think also resetting the oil life on the transmission and transfer case using ISTA has made a performance improvement. I'm gonna try cleaning the VANOS valves as the fact that the car hasn't been driven in a long time could explain this behavior.
Will update once I get it done.
???
Great, it is so helpful, I did it in the morning and it worked. The only thing not clear to me is what to do with the oil in the main part. Isnt the vanos going to be the same again when we put it back in there? As I could not clean the inside, I am expecting to have same issue?
If you put it on inpa you can see whether the cams are operating properly, while it's running. You should replace those seals and change the oil while you're at it. Makes a world of difference when these things are operating properly.
What is inpa?
Thanks for sharing. Easy to follow and saved me mucho dinero $$$
My issue just turned out to be that little red box with the fuse on the battery. I just changed that fuse box thingy and got back to normal. Hope that helps
Probably wouldn't hurt to change the oil too? There's a reason why those solenoid valves are sticking or plugging up.
Could brake clean work as well for cleaning?
hello
I have a 2000 BMW 528i e39, the EML light comes on, I fixed the PS valve on top of the trottle, and in the spider it has a diesel valve that is not a trottle.
nothing!!! how to fix that code
thank you
I did the same on a 05 523i e60. But i took elec wires and test them on the battery.. So immediately i can tell top solenoid was fine and operating normal. You can hear the solenoid ticking. The lower one not good, although it tries to work you can tell its not operating good. So i cleaned it with break cleaner and immediately you can hear working again. So ok, fault codes were gone and the engine ran great.. But, the next morning that lower solenoid were giving me trouble again. After replacing him alone the car is fixed. Cleaning is temporary you have to replace them
Daniel Theron what codes were you getting?
I’ve got the same code, haven’t replaced anything but I bench tested the solenoids, they work fine. Cleaned the solenoids up and put them back in, didn’t fix anything. I did an oil change afterwards and it was blackk said the last service was 2020 so would it be good to start with cleaning the solenoids again? I was gonna test the cam sensors too
I don't know if he ran the car earlier and it was warm but when you start a car like this it doesn't just run off of the whole system for the first 30 seconds to 1 min. It uses a program from the computer initially then cuts over the all the sensors and things to make it run more efficiently. So he needs to wait until it changes over to the secondary idle before he sees anything change or not.
@Arnold Rimmer Good point. I stand corrected. LOL.
Hey Nathan I removed my selenoids to clean them but did not see that seal in the middle , on any of them ....
Lmaoooo
Thank you for the info but do you think a bad o2 sensor can also do that surg and funky idle, downstream o2?
I just replaced mine with a new pair but the idle is rough any idea why?
Great video. But I have a quick question! On my 011 328i xdrive when replacing the vano do I have to do some type of reprogramming or adjustment. Or its just a plug and play selenoide? Any answers will be well appreciated.
@Jose Hernandez thank you .
Hello ,y have the same eror kep showing and the engine knock when warm ..
How do you register a new battery for a bmw 528i? Or do you even have too ????
The parts cannon is main stralers' favourite tool 🤣
I had a code for the B camshaft bank one I cleaned both vanos solenoids now the car runs worst and idles up and down! Light came on for P052 and misfire codes. Any guess what it could be? The connectors are plugged in the right vanos
Also there is a guy on here from UK that update has worked for him as well. But still check all sensors to make sure they wornt damaged before update and also complete all recalls before doing updates.
What was brand of the scanner tool?
Had p0012, i already changed spark plugs, coils, valve cover gasket, cmp sensor, and my 325 had a Recall for Vanos replacement. And still get the p0012 I cleaned vanos solenoid and vanos filter maybe not enough cleaned but any other suggestions? Lost of power and rough idle at star then has a steady idle
@JDe-wk5pc camshaft position sensor
Hello Nathan, is that tool able to code a fuel module and register a new battery?
What I do about every 30k is clean these solenoids and switch them around. There’s a guy on e90 post who has over 300k on his e90 and swears by this...
Shane Sexton How do you clean them?
search on youtube "how to clean solenoids e90"
Tried to clean and switch and no difference, replaced the vanos and ran better.
Every 100,000 miles they should be replaced. Bmw electrical needs oem sensors
Is it safe to switch them around ?
I'm having the same exact issue with my 2011 X3 xDrive35i I will definitely check this tomorrow and clean them and see if it works
i was put into limp mode on my bmw 335xi my belt shredded replaced it and now i got the p0012 code this is my first problem with my car i believe its the solenoid but the mechanic whats to take apart the engine and make sure there isnt belt can i just get the solenoid replaced and oil change to prolong until i get paid will that work?
So I shouldn’t get a new once and replace them? Just clean them and should work?
I’m not good at this, but I got the code 12 as well on my x5 2010, I’m not sure how to now if they need to be replaced
My shit cutting off everywhere I think battery is bad when it cuts off I can usually crank it back but today had to get a jump . Imma change these again and the cranksensor understated
use a 12v power source and actuate the unit several times while spraying cleaner
Are these the same sensors, why was there a red mark on one of them?
I have a bmw e90 and l recently did my service changed oil, oil filter, plugs and air filter but l am still having a problem its consuming a lot of fuels 14L/100 and there's white smoke at the exhaust pipe and l smell unburnt feul also with a rough idle any idea what the problem is.
Is there anything besides the vanos and mass air that i should clean to stop that surging? My 2010 528i only does it when im stopped. Thanks for the knowledge.
Jeff Rankin did you every figure out ur problem I have the same problem
@@4ktslime195 yes. the #4 coil pack went out, coupled with a pully sticking
Vanos filters
Is mass air flow cleaner ok to use ?
Hey, a huge thank you for this video! I have been dealing with the same problem on my 2010 X5, but not any more. You are the only person that seems to be down to earth with an easy cheap fix/troubleshooting (and no b/s talk). I was able to follow your video while doing an oil change. I finished cleaning and reinstalling before the oil finished draining! Thanks man!
Haven’t had a oil change yet but clean my vanos and it ran perfect for 30 mins do you think there going bad or I just need a oil change
I was getting a camshaft intakr code p0010 change both cam position sensors code still shows. Swapped vanos after cleaning two times intake/top 2 exhaust/lower and threw a p0013. so i ordered only one new solenoid after market since i heard they work fine and seems like only one is bad after swapping confirmed. Now the car is throwing p054b than a p0015.
I don't have a check engine light but I do have a surge problem especially sometimes in reverse or forward when starting the car now it's at the stop sign so even if I don't have a check engine light can I still clean this
My belt shredded to pieces and I believe it may have gone into the engine will this code pop up ?
I have errors p0012 and p0015. I need your hint. I have to change the solenoid and the cam sensor. Or is it just the sensor? waiting for your answer. Thank you!
What did you end up doing
I cleaned the solenoid. errors are gone@@KazTere-yn2lr
I change the valve cover gasket on my 2008 e90 but now I have misfire on cylinder 3-4 no spark what so ever! I swapped the ignition coils around but problem continue. Any help in pinchi pointing out the problem?
I C you got oil in your cylinders dry it out , did you replace your cylinder gaskets with the vcg? You should if you didnt
Did you ever find your problem
I have a 2008 X3 3.0SI with the N52 with 107,000 miles on it.
Shortly after purchasing it I got those two codes. After searching everyone said it was the vanos solenoids. So I replaced both of those with OEM parts.
A week later the codes came back. I bought another vanos solenoid thinking maybe I got 2 bad ones. I replaced just one of them. The codes came back shortly after and it again was both intake and exhaust at the same time.
I took a shot in the dark and replaced the vanos check valves, the codes still came back.
Then I replaced the camshaft position sensors thinking maybe they were just broken. The codes still came back.
When the codes do come back it is usually just after startup and I can feel the engine surge a bit, and then it throws the codes.
Curiously every single time it throws the codes it is both intake and exhaust at the same time.
I think it might be the vanos actuator motor?
To summarize I've replaced:
Both vanos solenoids
Both camshaft position sensors
Both Vanos check valves
Either way I want to stop throwing parts at it in hopes it will fix the problem.
Any idea.
Please I need you help I know you own bmw.
Thank you for you time.
Im having the same issues I replaced both solenoids and crankshaft and camshaft sensors still getting p0012 and p0015 codes it's 2008 528i bmw. I will note all this happen after a delayed oil change smh.
Trying getting a firmware update. If that doesn't work, your cam bearing ledges might be worn. That usually means a new head.
The firmware update has been working for people though.
Did you clean your vanos filters? There is a video called "non return vanos filters". The guy pulls the filters out, cleans them and it fixes the problem.
@@MrTruthAddict Braxton European came up with worn or damaged crankshaft gears that needed to be replaced also with some fluids changes like trans and coolant but it came up to 2500$
@@eazycontent1830 they're lying to you. Crankshaft gear? Find another mechanic. This guy is trying to rip you off. It's probably your cam bearing ledges that are worn out
Great job man. I have not fixed my car yet but I will try. Thx
Hey Nathan I own a e65 having a rough idle and surging power took it to mechanic showing code 27bc giving misfire mechanic says something about the camshaft any help ?
hello
i have a BMW E91 320i 2006 model and the last 1 year i have always the fault code 2A70. and only this code.
i delete it but it comes again.
i change battery,coils,spark plugs.still the same.
i have no power loss ( i thing ) but increase fuel consumption.
It can also be the one way anti-drain valves.
Stankin Walmart LOL last night I went to Walmart perfectly fine come back out now it's running rough but no check engine lights what the heck is going on any information would be highly appreciated thank you
Do you buy both of the same sensors or are they both different sensors??
Can u use WD-40??
Have you fixed this issue where it stalls and it doesn’t respond when you hit the gas
Last time that happened to me it was my transmission. Got it replaced for 2500.
Same problem here did you fix it yet ? What was it for you ?
Nathan if you have installed LED bulbs anywhere on BMW, you can use NCS EXPERT to disable cold and warm check on those places so you will not get that annoying warning on dashboard. On my E53 N62 I did that in LMA module. Just read it out and in Notepad you should change:
Parking Lights / DRL Cold Check Left : AUSG_04_POL_L_KALT_UEBERW_AKTIV
Parking Lights / DRL Cold Check Right : AUSG_05_POL_R_KALT_UEBERW_AKTIV
Parking Lights / DRL Warm Check Left : AUSG_04_POL_L_WARM_UEBERW_AKTIV
Parking Lights / DRL Warm Check Righ : AUSG_05_POL_R_WARM_UEBERW_AKTIV
to NICHT_AKTIV and upload it to module.
So you can use LED bulbs for Angel Eyes without error on your dash, also you dont have to put those resistors which are heating inside the headlight.
Also for other bulbs replaced with LEDs.:

Also if this would have not fixed it you might have a crank sensor problem. When I got my car after standing for a while it had rough idle and long starts, apparently the rats ate threw my crank sensor wire near the starter so I fixed the wiring harness and it runes good now
".. apparently the rats ..."
talking as if we all have a rat problem ...
how u get rid of the check engine light thoe??
my bmw E90 turns on everything comes on fine but rpms don’t rev past 1000 the tac jumps up and down when it’s sitting, plugged in my scanner and it threw a code for valvetronic motor. car is in limp mode, what could be the problem?
Thank you!! My engine is now more responsive and idles like a good, i Will have to see if it comes back and in that case buy new ones
yep that sounds right , if the solenoids were leaving the timing advanced on the next start up the extra advance and the early combustion before tdc would cause the slow cranking and the abrupt stop of crankshaft rotation when the crank tries to turn backwards , that would also triggers dtcs , misfires-backfires, cas sensor sync, ,
makes you wonder whether manufactures are over complicating things , I know the development of bigger and faster processors in ecu's with more feedback channels to the ecu and this has resulted in more efficient, smoother running engines with more horsepower and torque and at the same time the increase in data feedback to the ecu has not improved the diagnostics ability to pin point faults, the older systems were more straight forward .
when a mazda 3/6 throws a cam angle sensor code when mechanical failure of a friction washer cause the crankshaft sprocket to move is due to poorly coded firmware and flaws in the designs of keyless sprockets that were implemented to save production costs , that end up costing the customer money and independent mechanics time and money.
with all the telemetry data available at the ecu these days surely the software engineers could create a system with a on board user interface that is not as vague and draws a more complete picture, it looks like the dealership service departments need it.
some scan tools work better than others and that probably due to being able to connect with the proper protocol in order to read the data but at the same time they can only work as good as the obd system that they connect to provided that the tool has no errors in reading the data, i have experienced different results using different tools on the same vehicle.
I have seem the merc and BMW scan tools that the dealers use, it was software on a laptop and it was pretty elaborate
may I ask how much the scan tool was, because i have searched and found the same ones online but I see some priced at $130 and other prices at $400.
@Arnold Rimmer If you have some tuning experience ? Or Have ever set up an aftermarket Ecu and cranked an engine for the initial start with to much ignition advance
Normally the fire is lit some crankshaft degrees before tdc and the crank has come over to where the force of the piston pushing down and the crank is past Tdc causing the crankshaft to rotate in the right direction that advance Is for the delay in combustion
If you light the fire to early the piston is still on it’s way up and not past rev and the crank hasn’t come over. The piston will push the crank back in the direction it came from. You will notice this as an abrupt licking or even backwards motions when you crank and engine with to much ignition advance
The engine doesn’t actually start up and run backwards
Hence the term trying to run backwards
It’s a term tuners use to say to much ignition advance at cranking
@Arnold Rimmer you obviously have no experience with dyno tuning vehicles and you’re not familiar with the terminology. Don’t be so quick to try and make people look silly
Did you even stop and try to think about how what I said can be mechanically possible ? No of course not
Coz you thought you had me
Buddy I’ve been tuning cars for 15 years
Built an r33 gtr skyline that made 630kws at the rear treads and an evo lancer that made 403kws. Never at any stage we’re you going to stump me or did you have me got with your amateurish comment and as it turns out the reverse gear push start is not the only way an engine will TRY to run backwards when cranking Read the words carefully. Don’t be so quick to try and prove. You know everything
what direction would you be pushing the car when you use reverse to start it
This is one of the stupidest things I have also ever heard and like you said why would anyone do that ? Why would you even try and explain the only way you think it’s possible. Is it because you think that were are all so stupid and only you can figure that out ?
But there is no point to what you are trying to say. You want to avoid having that issue with slow cranking or lock up and backwards motion at cranking
@Arnold Rimmer but I am glad you used the words “I can’t see how” instead of “it’s not possible for” the crankshaft to rotate backwards during cranking just encase I had the answer
@Arnold Rimmer I used the aftermarket Ecu and tuning as an example so it’s be easier. To convey and understand the issue can arise with Unmodified vehicles, ignition base timing. is not always locked in one position. Some have the provisions for adjusting the base so you end up with the actual timing matching the timing that the. Ecu map is
air temp sensors or. Coolant temp sensors will advance and retard substantial amounts of timing and faulty sensors could cause the described scenario
A faulty air temp sensor that is stuck on a resistance that tricks the Ecu into thinking the air temps are -10c will trigger compensation table that can add fuel to the base fuel . Maps and to ignition.base maps
I don’t remember what this video was about and I’m sure my comment was relevant otherwise I wouldn’t have made it and I’m sure as hell not going to watch it again because you are not familiar with the terminology and are having trouble accept what it relates to
Whether average joe or not
it would benefit joe if he actually took the time to learn how it all. Works
Whether a race car or production car that you by from a dealership
It’s all the same
Do You realize that the averages joes family car was also dyno tuned or the configuration. That makes run cams from an exact copy vehicle or engine which spent 1000s of hours on a dyno in order to refine the tune so every possible scenario is covered and the engine doesn’t mis behave In Extreme conditions like cold or hot weather. Altitude changes etc air temperature. Air density and even different fuel octane in some vehicles or e85 content compensation
The issue is that you tried to make a fool out of me and you thought you knew what you’re talking about and now you’ve been schooled on the topic and your back peddling
Don’t be pissed off at me for having extensive knowledge in the field that I spent 15 years in. For a living. Everyday
Be disappointed with yourself for trying to troll someone and making an ass of yourself Instead of them
So now you’re just talking about one specific isolated issue are you ?
I think you are just talking rubbish
You don’t know what you. Are talking about. But you thought you did
I don’t understand what you mean
Are expert knowledgeable comments not welcome
Only average joe comments are permitted
We don’t want to over complicate things and actually learn how things actually work
You didn’t know how and engine can try to run backwards while cranking
I explained it
I don’t see and argument saying that my explanation is not actual fact
And now you do see how an engine can in fact try to run backwards while cranking (is this correct ) you do now understand ?
I explain how it is possible I’m all types or vehicles. And it’s all related to ignition timing
So that would include any vehicle with a
Piston engine running spark ignition
To much advanced
Engine try to run
Backwards
No exceptions
What's the name of Obd2 scanner you were using
MaxiDiag
Mine is doing the same thing with when you hit the gas it’s like a power band
what did the problem end up being?!

in the morning there is a little rough idle but not more than when car is hot
what could you advise me to check first ?
please note beside problem idle my car runs and drive like a dream
My N52 (on a 7 series!) fluctuates once after every start - could it need this cleaning as well? Or is it the DISA? No errors codes or check engine lights. I changed the oil separator and pipes, did not cure it. Engine runs beautifully other than this annoying throttle blip on startup
Did you find the fix?
Haveing the same issue
Yes the N62 has the same issue. It just has four vanos solenoids instead of two. Cleaning them and replacing the rubber seals will fix the problem. Make sure you use good oil and don't let the oil get dirty. It will clog up the oil galleys and you'll have this problem again.
They said it was my vanos, still getting code, and I only used bosch
What kind of spray i can buy the name to clean
Any carb cleaner is ok
Man, I felt his pain as he started speaking.
My n52 6mt will burble in w.o.t. under 3500 r.p.m. Sometimes it throws a engine light but service scan reads o.k. Could I let those solenoids soak in carb cleaner overnight?
whats your OBD reader model ?
You would not believe the problems you would have with a week battery . the engine races and never idles down . the fan sometimes don't work on high until you drive it for an hour... And then if you get a battery that is 90 or 80% brand new you still have problems...
Cleaned my Vanos on my 07 X5 3.0, 2 years ago and never got the code again.
hi hathan i have 2010 bmw x3 177000 mile getting cylinder 4 and 6 misfire, changed coil and sparkplug and also clean the vanos selanoid but still getting the misfire and car hagistate at low rpm (Rough idle) any idea what could be wrong also changed valve cover gasket
Hie, did the missfire code vanished or is it still there?
@@tusharhire790 still there yesterday I have cleaned all fuel injectors but still getting same misfire code cylinder 4 and 6
Nathan thanks for your videos. I bought a E46 M3 for my daily driver. How hard is it to complete a service 2 for my 90k miles? Should I try to check the Vanos myself? I'm good for basic maintenance but not sure if the Vanos is too involved. I just changed my alternator but that seems simple in comparison. Thanks.
Super easy
Will this work on n62 motors as well?
Would this cause my car not turn on
Nathan my 335i n54 has had a rough idle recently it will come and go ...but at idle it will idle and then drop down to about 200rpm or so , bring it back up and then trys to stall and catches itself ...can't find any vaccum leaks , injectors were replaced a couple years ago , high pressure pump was replaced under warranty a few years ago. Think maybe the vanos solenoids could be the issue ? I have no engine lights other then one code for an evap pump .
Have u ficed this !
Thank You so much my car is doing the same thing
When should you replace them
