With absolutely zero car knowledge your channel has saved my car. It was in brutal condition when I bought it, and now it runs like a gem. Appreciate it brotha
your welcome Jordan mate im glad it got your car rectified mate and thats why I do these videos hopefully you guys will keep this car so then you can always stay tuned to my videos mate
She’s at 265,000km and still going strong. Just hope I don’t wreck her in this Canadian winter, it’s my first RWD car in this winter. Had a Golf before this and if I ever wreck this car that’s what I’m gonna go back to
My golf was the best car I’ve owned to this point, I think I’d go TDI or GTI if I got another one. I had a golf city just cause it was cheap and I didn’t have a lot of funds at the time of buying it. Would love to get another
Jordan Sass had a Jetta 2.5 last year of true IRS, then the trailing arm was the next model rear suspension. That car had everything in exactly the right place. Couldn't afford the Wolfsburg edition but loved the car. Even though it was made in Mexico it was a great car as well. Good luck with the winter, doing the same in the north east states, lil snow is a blast a lot is a pain
Thanks for your help Dean. I have an E46 with 26X,XXXmi I've had for 6 years and put 140,000 miles on, just purchased and X5 with a N52 and 167,XXX miles. I'm going through it. and needed a list of things to check. Between you and Nathan, I feel confident I can get this beast back to snuff. Just did the OFHG and OFcooling gasket. Vanos Solenoids, Thrust arms and end links scheduled to arrive today. Had to do the wiper fluid pump last week. Disa and CCV is next.
I bought a 200k mile 325i manual and videos like this have kept it a happy machine. I lost the water pump once in a dramatic explosion of steam. Fixed it for 150$ amazon replacement and a 10$ metal hose flange to replace the original chocolate hose flange. Lets go another 5-50k miles :)
Just picked up a 2008 125i cabriolet manual with the N52 with 104,000 miles and it’s got an oil leak dripping oil near exhaust manifold, I’m going to order the replacement and new bolts this weekend. Paid £3400 for her and don’t mind paying to bring the engine and components as close to new as possible. I’ve had DSG golfs and stuff in the past and I really have a soft spot for the configuration of this little car N/A 6 cylinder, 6 speed manual, RWD, Coupe. this is now unheard of!
Learning so much from your videos!! Can’t wait to start building my N52, currently have a 07 E90 328i sedan and I love it so I can’t wait to squeeze some power into the car
I disagree about the temperature gauge. They could easily include one set to the appropriate temperature range of the engine. Ie hot for hotter than normal. A gauge gives you warning of a temp increase before it's critical
Thanks for the video - useful information. I have changed everything you have identified except the disser valve. However I waited until I got codes or other faults. I only replaced one coil not the hole set. A new coil on one cylinder does not put extra load on old coils as they are completely independent of each other. The only additional item I had to replace was the starter motor. Sold the car with 320,000 kms. The new owner has the full history of the items replaced. PS - changing the water pump and thermostat requires the coolant to be replaced and should be the only time anyone needs to touch the coolant.
Love your videos, I have a 2003 BMW 735i E65 3.6L with 75K on the clock, I'd love you to do one of these videos on this model please, it's my weekend car but looking at doing all this sort of maintenance going forward as the mileage heads over the 75k, thanks pal and keep up the good work, wish you lived in Ireland, I use you as my mechanic, hard to get a genuine honest mechanic like yourself 🚘👨🔧🚘👨🔧🚘👨🔧👍
Just bought a 09 328i from a Police Impound Acution and it has 188K miles, so this helps on what I need to get changed, just the other day replaced the starter, crank sensor, oil housing gasket, intake manifold gaskets, oil pressure sensor, crankcase vent...the intake has a lot of oil inside of it as well.... and will be replacing all the vanos BS and installing a Aluminium valve cover and of course the belts and transmission service.
Many folk here would love to know what you meant by "updating the software". Would be great if you could provide a short guide on this. Thanks for all you do!
These are pretty good engines, mine is at 120k and I've only had to do starter and valve cover gasket. My oil pan leaks alittle but it's not enough to run out and replace it right away as long as i add a quart every month it's fine
I did water pump and thermostat if your o2 sensors are failing on a N52 engine you have big problems mines on 160k on original sensors with no issues I would change your fuel grade and run shell v power 101
This is all spot on. My 180K N52 (328i) has all of these except the vanos done. Most items got replaced at ~80K. But did my coils and second set of plugs about 170K. The valve cover had to be replaced because the CCV is built into it, at 175K. What a stupid design that is. At the current time I periodically get an oil burning smell, but no drips are visible on the car or the garage floor. Any ideas?
Excellent information. I got 220,000 miles on my 08 528i and have already gone through the valve cover gasket, spark plugs. Football gasket, eccentric sensor, oil filter case gasket, expansion tank, battery and vanos solenoids. Im getting ready to order new vanos solenoids again 4 years later. The waterpump still has a strong jet of coolant at the expansion tank. Are the motor mounts a bad failing point for these cars? My 528i makes a sound right at the start only and dont know how to trouble shoot it. I know my sister is having her motor mounts on her 07 328i replaced due to a rear end collission. As soon as she got hit, her cars started vibrating like crazy. Just like I thought, it was the motor mounts. Keep up the good work and thanks in advance.
Engine runs GREAT ! I had Mom appointment for her to look at a Subaru... They had sent it out for detailing and pulled the gold onto the screen. Mom said , " I want it, I'm tired of looking. For $11,000, Mom got the E60 N52 528i 2009 (or 08 * lol * ) - 88k miles - in May '22. I asked sales rep to pop hood after test ride (10 miles maybe) ( with a weird disturbance mid run). Residue all over, but not thick black... Just moistened , so I asked what was leaking... "Oh nothing, probably last guy to oil change spilled a little..." After home a month, total brake and rotors, then top front coolant hose connector (one of many things readily emitting residues). So then oil cooler filter housing gasket change and pulleys belt and tensioner, valve cover gasket.... But a vibrating was irritating to Mom ... I re-lubed/replaced caliper pins, no fix... Then recalled for pcv valve tube change... They told me needed rotors ... The ATE's I got for it weren't quality enough .... BMW's rotors next great, but pinhole steering fluid leak low pressure and old intake clamp inches from steering pump pulley made belt jump and shredded everywhere... ugh....a piece melting belt clabbered on the water pump bolts and melted up the rubber washers.... NEXT....
I've done the OFHG so many times at this point, there's really no issue doing it as needed whenever they do start leaking. E60 with about 50k since the last OFHG and oil cooler gasket replacement and its already starting to show major signs of leaking again on to the belts and the hoses. Thanks for the video!
Bywall that only happens when you use cheap gaskets and not original bmw ones because I can tell you now mine ain’t leaked again and neither has anyone else’s stop using the cheap crap offline and go to bmw and buy it £35 for both gaskets
Bmw Doctor I’ve used Victor Reinz/Elring/Ajusa brand gaskets my whole life. I’ve even tried to source the newer viton rubber gaskets but at this point it almost seems like a design flaw. I feel as a result of running so hot, the gaskets on the N54 and N52 start to leak again and and again over time
Also interesting to note that my e90 which has the N52 OFHG without any oil cooler is also showing signs of leaking at 80k, but this is likely still the original gasket from 2010.
Bywall mate impossible in trying you that now you either ain’t doing the gaskets correct or you ain’t cleaning the area before fitting and there not sealing correctly I have done this ONCE on my car since ownership and have had no issues I also did this many many times on previous N52 for other owners who are on here and they ain’t complaining so mate you must not be doing it right If I was you mate take it to a garage and have them do it PROPERLY
Bmw Doctor that May very well by the case. I’m hoping now with practice I’ll be able to do the job properly. Again, thank you for all the content you put out. It’s incredibly helpful!!
Thanks for the part on the valve cover bolts. My records show the valve cover gasket was done ~20k miles ago, but I just found a leak and a couple of the bolts could be turned by hand!? I had just changed the CCV system and it was crap. So either they torqued em wrong on install, or they were loosened from the increased pressure like you said. Once again you clear up a strange situation.
Yes mate I’m a expert on this engine as you know mate that’s why a lot of people wouldn’t expect this and expect them to be loose but trust me this is what happens
@@BMWDoctor how do you feel about BMW dealer servicing? I find they are not meticulous and sometimes do sloppy work. I've paid a fortune keeping it BMW Certified by going to the dealer. any suggestions?
Hey bro I brought a BMW and I was a bit scared when I saw some issues, but your videos give me hope I can repair it even by myself with no experience, I hope we can get this running smooth 👍
Hi dean. I am a international student and studying in Canada. I bought a 2011 328xi three years ago. Now it just hit 100k km. I am planing to change those parts that you mentioned in this video. But I am having a hard time to understand your speech. So can you make a list that could help me to find all the parts easier? and how I can do the engine module update? 0:45 for the engine oil filter components, do you mean need to replace the whole engine oil filter housing parts, not only the cap. is that right? 4:05 do you mean the CCV intake manifold needed to be replaced? 5:00 do you mean the valve cover gasket set need to be replaced? and for these bolts what size i need to get?
2011 N51b30 done two oil changes already with 5w30 just ordered 5w40 🙏🏼 80k 👨🔧 done my oil filter housing gasket, started seeing it fail on the cold starts...bolt behind manifold is not bad just have right tools 🛠
It's not that hard to do all these things. Really good info. The secret of motoring is to concentrate on the weaknesses of whatever you drive. This has been true since the beginning of the car.
Whoa bruh slow down a bit lol.. but do appreciate the knowledge you give. I just picked up a 2010 x3 and .. man... ??.. yeah..didn't know nothing about bimmers and watching your video gives me some ease at what I NEED to know as it didn't start when I got it and now it does... but lack of power when acceleration so still trouble shooting
I bought a 08 BMW z4 3.0si with 127k on it. It seems everything has been replaced from just looking as for what I can tell. The Valvetronic gasket is the only slight leak it has but I am replacing that this week. I think the Disas have been replaced but not 100% the top caps are green in color if that makes a difference.
Thanks for the video. As one may not have time or money to do or have done the 9 things at once, could you please advice for different operations that could be grouped so that we would end with say 4 or 5 batches ?
@@BMWDoctor No, not that. You just sound like you are about to punch that N52 one time, two times, ten times and then burn it down or maybe use rocket launcher to destroy that over engineered piece of crap.
sorry man, maybe is because my understanding in english is not the best, but I couldn’t understand what kind of updates were u talking about at min 3:45 (like a software update? something that they can do at the BMW dealer or what?) thanks in advance
Great video! I have the problem that my N52 engine has a rough idle only on cold start. Already changed the spark plugs, solenoids, chain strengthener and the twi DISAs on the engine. What else could I replace?
Wish I knew this before I bought one. I have done 6/9 of these. You didn’t mention sump pan gasket. Mine failed around 250,000 Klms but from looking around seem a common failure at around 100,000 miles.
Mate I didn’t in my common leaks This wasn’t relevant on this video you have to understand aswell this varies country to country is being in the U.K. this is not likely the case here you may see loads of them like that I have only seen 2 in my time out of 300 so that shows why it wasn’t mentioned
Around 100k is when you need to replace the expansion tank, those almost have the exact life span of 100k. It is hell trying to get it seated right, and if yours goes, it sprays everywhere and possible shorts the fan, and a few electric components. Is it also true to replace transmission fluid around 100k, and BMW Lifetime oil generally refers to 100k?
Every point you made was what I call ENGINEERED FAILURE POINTS. They are specifically engineered to fail at a specific point to force the owner into the shop for a costly repair. Every auto manufacturer uses them to get into your wallet. All a part of the automotive corporate plan.
@@gtmike916 actually, to me, planned obsolescence is a separate concept; designing a vehicle to look outdated. It will run perfectly, but just look old, enticing the owner to "update" by buying the newest version. Engineered failure is used to force owners to repair items that should last longer if not fail at all. An example is the electric water pump on the BMW. Mechanical water pumps should last well beyond 100K, but you're living on borrowed time after only 50K with the BMW pump. Or the door latch mechanism in a Ford Edge. Some electronic gizmo fails to work after 15k, forcing you to pay well over $700 in labor to replace a $30 part.
Planned obsolescence is a part that is designed in a way that it will no longer serve its purpose after a certain duration or determined wear quantity. Engineered failure points is not a thing, that’s called engineering for cost vs longevity. You could upgrade the material and design of every component on the car but there will always be a weakest link, the car would last longer overall but you will always get a part that will fail eventually, it is not only expensive to engineer parts for that, but also pointless if your top 60th percentile of vehicles doesn’t make it to the age at which these over engineered parts would last, they just become heavier landfill.
6. Water pump and the thermostat a. Replace these. You do not need to change the coolant. b. Don’t worry about the warm temperature if the car is not overheating. c. Costs about $50 - $120 Not sure where you're getting your water pump. They're over $600 here
Hey Dr. Love your video! I’m getting a weird idle on my car. Only on first startup, goes away when it’s been drove for a bit. Do you think it’s VANOS solenoids or Plugs/Coils?
They could have put a temperature gauge on the cars. All they had to do was to design the gauge to read normal unless the temperature is out of tolerate according to water pump operation thermostat operation and the coolant temperature itself. All my cars the temperature gauge sits exactly in one spot no matter what. However outside of that parameter it will show a higher reading. You are right I was thinking since the electrical water pump and thermostat came on BMW's they took the coolant gauge off at the same time. So it makes sense.
Hi mate . Maybe a silly quistion but after replacing vanos solenoids you mention updating the modules ...is this the same as an ecu remap or should the actual engine module be replaced ? Great videos ...learning alot
No mate you update the module using genuine bmw files I have done it for many many many people with success No remap needed for this and no module needs replacing just updating
@@BMWDoctor ok so is this something I could get done threw you or your company ? If not any recommendations on where . Iv got a 2007 330i e90 Iv had for a couple years currently on 87000 miles and im starting to do some small upgrades and preventative maintenance on as I love the car and want it to run at it's best . Thanks for any info or advice you give . Best bm vids on TH-cam hands down
Just bought a 2007 530i with 240k but it runs great. It was maintained really well the car drives and looks loke almost new. What should I keep an eye on at 240k
You have said to update the engine (what do you mean by that)? And if i have the n52 without vanos solenoids can i put them and how to make them work with the ecu
Any chance you know why my oil cap would be leaking after I replaced with genuine part? also rocker cover gasket done by previous owner is now leaking ? Plus my brake pedal goes stiff at 1k revs any ideas on this ? Servo or vacuum pump ?
I have a question about the solenoids I have some issues whit my n52 we did diagnostic and found that 1 of the solenoids is not working the car is lacking power and is slow on the trotile when. i press it hasetate to speed up. I am waiting for the new solenoid but I wonder is it possible the rataling noise to be from that as well. because it didn't show nothing else on the computer? will be. super thankful for any advice sorry for. my bad english :)
Dr. BMW! I have a question I recently purchased a 2006 Z4 with N52 engine and only has 6k miles on it, kept good and checked engine bay very clean no oil leaks. I've done the oil change and windshield sprayer waterpump. Is any of the 9 points I will need be alarted soon?
The best upgrade on my 2011 X3 with 100k somewhat problem free miles was trading it for a Lexus.... these 9 problems, and several other more was the final straw on a long list of things that cost way more than the car was worth to fix. I also have a 2013 328i F30, with 143k miles on the 4 banger...zero problems, but its not worth two dollars so I just tool around with it until the engine has a catastrophic failure....
Interesting, yeah I have heard that the 328I F 30 is pretty reliable even though it’s forced induction, I am so torn because I love the Bangle era E 60 and I’ve always wanted one, was thinking about getting one as second car but I am also considering a A6 3.2 which is supposedly quite reliable actually. However I do love the F10 five series as well and a 528 I would probably be a reliable right, Of course with a thorough inspection and proper maintenance history
What's that silver looking pipe on the left side of the engine? Mine is open for some reason it doesn't look right but I don't know what it is. Learned loads from your vids tonight though, cheers.
I agree .I have E60 523I 2006 170K miles. Gradually I had to change everything.Still oxygen sensor rear, IBS sensor, oil level sensor and voltage regulator in alternator.
Would you recommend I change everything on this list in one go as I'm nearing the 100k mark? Or am I too paranoid and I should just wait for initial problems to appear?
Hey doc, any advice on changing the transmission fluid on n52 after 100k? was going to change mine it said "lifetime fluid" which doesn't sit right. I've got 160k miles on it!
Changed the valve cover gasket, pulley and tensioner at 70K miles in my 2008 E90. Next will be the ABS assembly, I am sending it out to a third party for repair. Thank you.
Thanks for the video! In addition to the tensioner, idler pulley and belt, do you recommend changing the crankshaft pulley/harmonic balancer after oil leaks have been fixed? My understanding is that the rubber in the pulley/balancer can deteriorate after being soaked in oil for a while. Could this part failing be the cause of increased engine vibration at idle? Should you change just the pulley (removing 6 small bolts only) or the pulley plus the backing sleeve thing that is held on with the single bolt? I'm concerned about messing with the timing by removing the whole part with the single bolt.
So when I get a used e91 wagon here shortly. Basically just replace all these things or should I risk it and run the car as is for a short time first?... And if needing to replace all these it wouldn't make sense to pay big dollar on the car just cause it has 70k or less on the clock. When could just pay a lot less for a car with 100k plus on the clock. And use part of the savings to do a bunch of this work yourself possibly. While getting to know the car more when working on it.
exactly the same on my Benz money pits: Filter housing gasket Phasers stuck PCV burning oil partly developed software valve cover extra leaks weak aluminum bolts serpentine idler and tensioner .... Serious Ticking come from high pressure direct fuel injectors last: don't forget to do early drain on transmission oil and brake flush... all engineered for precisely controlled premature failure to help Japanese partner brands 👍
My 06 E90 325i with 55k mileage both valve cover gasket and oil pan gasket starts leaking..The valve cover is easy to work but the oil pan gasket was a pain,It took us 2 days but we managed it.
Excellent video mate keep up the good work 👍Have a good week what do think about the 3cyclinder supercharged mini engine?I was thinking about getting one
mate I havent a clue about them haven't done any research on mini anymore mate as im selling my one mate had enough mate doesn't get the views and the people are ignorant mate who watch cant be bothered will stick to my loyal bmw guys who all support me and care mate
Have an 325ci with the great m54 engine it has now 270000 km on it and runs fine only issue i had is the disa and the timing chain wich beckomes a bit lose
well I have 2006 530i with N52 (310k km) and the only things I replaced so far was a starter, front spring and connection link on front sway bar. And belt and tensioner at 200k as maintenance, and just standard maintenance stuff, plugs, pads, filters etc. Otherwise no issues, no codes. The only extra things i do is oil changes every 8-10k, and oils in man. transm, and diff, every 80k or so.
hello doctor, many thanks for all your videos, :) but ! if it's possible in your videos descriptions or commentary can you list pieces your talking about,? it will be more easy for non English people & for translation purpose :)
I get what your saying mate but that is not very easy to do I don’t think any you tubers do that mate as I know TH-cam do provide subtitles if need be I didn’t think I have non English people watching mate if I’m honest
Hello i just find your channel and i have n52b25 my one have 108k miles i change everything you say apart oil housing and tension with belt... Like you said everything start at around 100k but i sow allot of you videos now and i can see clearly that you know what you talking about is there by any chance you do inspection on other people cars? And if you do where are you base? Would like to bring my one to you for it btw great videos!
Is an N52B25 a good choice? The only reason for not going for 3.0, is `cause in Serbia, registration fees above 2.0 litre engines, especially above 2.5 litre, are very high.
Come back to me in another year let’s see if you still say that OR you just haven’t checked underneath your bonnet to notice anything but after this video now I showed you I bet you will please make sure you don’t do what the rest do say you have no issues then never come back and report when you do because of embarrassment there is nothing to be ashamed of saying you have issues it’s normal on N52
So your admitting the car has had problems 😁 as you said you do your own maintenance nobody will ever believe you making a comment like this I have 10k subs and ALL have had problems on there N52
Hello DR. I have a 09 528i and the ccv diaphragm keeps breaking I replaced it with the quick fix from Amazon because I did not want to change the intire valve cover , unfortunately it only last a week. Does the vanos cause that?
Don’t own the m57 mate anymore and won’t be getting one anytime soon mate wouldn’t want to own one buddy not my cup of tea and also it attracts the U.K. and Eu and sorry mate but the ad money is very very crap from the U.K. and Eu that’s why I try and do videos for the USA base more the diesel was just a one off mate to have the videos here but that’s it mate they didn’t do well and still ain’t money wise I have to favour what gets me the views and big income on TH-cam
I said water pump on this. also oil pan gasket has been mentioned in my previous videos it wasn't mandatory to do NOW and is not something I consider a major thing on this engine to do immediately it leaks yes but not severely that you cant drive the car.

can you add those parts in the description please.
Yes pleas
I disagree about the temperature gauge. They could easily include one set to the appropriate temperature range of the engine. Ie hot for hotter than normal. A gauge gives you warning of a temp increase before it's critical

Just wanted to ask how do you update the engine software since I just replaced my vanos solenoid?
Just bought a 09 328i from a Police Impound Acution and it has 188K miles, so this helps on what I need to get changed, just the other day replaced the starter, crank sensor, oil housing gasket, intake manifold gaskets, oil pressure sensor, crankcase vent...the intake has a lot of oil inside of it as well.... and will be replacing all the vanos BS and installing a Aluminium valve cover and of course the belts and transmission service.

These are pretty good engines, mine is at 120k and I've only had to do starter and valve cover gasket. My oil pan leaks alittle but it's not enough to run out and replace it right away as long as i add a quart every month it's fine
Me too, I am waiting for the smoke and the ejectable seat, then it's a James bond car!! :))
Thanks! I would add O2 sensors in engine bay, and the electronic water pump (+ its thermostat)
I did water pump and thermostat
if your o2 sensors are failing on a N52 engine you have big problems mines on 160k on original sensors with no issues I would change your fuel grade and run shell v power 101
BMW Doctor O2 sensors agree that basically never fails but some have noticed big improvements in fuel consumptions as they get aged.
This is all spot on. My 180K N52 (328i) has all of these except the vanos done. Most items got replaced at ~80K. But did my coils and second set of plugs about 170K. The valve cover had to be replaced because the CCV is built into it, at 175K. What a stupid design that is. At the current time I periodically get an oil burning smell, but no drips are visible on the car or the garage floor. Any ideas?
I have a 2011 328i and I’ve had to deal with these same issues spot on at around 73k miles. Excellent video!
how much did it cost to change all these parts??
Excellent information. I got 220,000 miles on my 08 528i and have already gone through the valve cover gasket, spark plugs. Football gasket, eccentric sensor, oil filter case gasket, expansion tank, battery and vanos solenoids. Im getting ready to order new vanos solenoids again 4 years later. The waterpump still has a strong jet of coolant at the expansion tank.
Are the motor mounts a bad failing point for these cars?
My 528i makes a sound right at the start only and dont know how to trouble shoot it. I know my sister is having her motor mounts on her 07 328i replaced due to a rear end collission. As soon as she got hit, her cars started vibrating like crazy. Just like I thought, it was the motor mounts.
Keep up the good work and thanks in advance.
You the reason why I own a BMW so I wanna say thank you
Engine runs GREAT ! I had Mom appointment for her to look at a Subaru... They had sent it out for detailing and pulled the gold onto the screen. Mom said , " I want it, I'm tired of looking. For $11,000, Mom got the E60 N52 528i 2009 (or 08 * lol * ) - 88k miles - in May '22. I asked sales rep to pop hood after test ride (10 miles maybe) ( with a weird disturbance mid run). Residue all over, but not thick black... Just moistened , so I asked what was leaking... "Oh nothing, probably last guy to oil change spilled a little..." After home a month, total brake and rotors, then top front coolant hose connector (one of many things readily emitting residues). So then oil cooler filter housing gasket change and pulleys belt and tensioner, valve cover gasket.... But a vibrating was irritating to Mom ... I re-lubed/replaced caliper pins, no fix... Then recalled for pcv valve tube change... They told me needed rotors ... The ATE's I got for it weren't quality enough .... BMW's rotors next great, but pinhole steering fluid leak low pressure and old intake clamp inches from steering pump pulley made belt jump and shredded everywhere... ugh....a piece melting belt clabbered on the water pump bolts and melted up the rubber washers.... NEXT....
Thank's . My issue was idle drop at start and a error on exhaust solenoid,after i clean the exhaust vanos solenoid i solve that.Keep up the good work!
I've done the OFHG so many times at this point, there's really no issue doing it as needed whenever they do start leaking. E60 with about 50k since the last OFHG and oil cooler gasket replacement and its already starting to show major signs of leaking again on to the belts and the hoses. Thanks for the video!
Bywall that only happens when you use cheap gaskets and not original bmw ones because I can tell you now mine ain’t leaked again and neither has anyone else’s stop using the cheap crap offline and go to bmw and buy it £35 for both gaskets
Bmw Doctor I’ve used Victor Reinz/Elring/Ajusa brand gaskets my whole life. I’ve even tried to source the newer viton rubber gaskets but at this point it almost seems like a design flaw. I feel as a result of running so hot, the gaskets on the N54 and N52 start to leak again and and again over time
Also interesting to note that my e90 which has the N52 OFHG without any oil cooler is also showing signs of leaking at 80k, but this is likely still the original gasket from 2010.
Bywall mate impossible in trying you that now you either ain’t doing the gaskets correct or you ain’t cleaning the area before fitting and there not sealing correctly I have done this ONCE on my car since ownership and have had no issues I also did this many many times on previous N52 for other owners who are on here and they ain’t complaining so mate you must not be doing it right
If I was you mate take it to a garage and have them do it PROPERLY
Bmw Doctor that May very well by the case. I’m hoping now with practice I’ll be able to do the job properly. Again, thank you for all the content you put out. It’s incredibly helpful!!
Can you make a video on updating the n52?
Man, you're so correct!!! I had all of those changed except the belt tensioner
i have a friend that has the same engine and never had any issues with the engine other than oil leaks. and now is 177.000 miles and still gOing
I liked and subscribed keep on bringing n52 stuff plzzz
I m confused about update part? Does he mean i need to bring it to some tech who can chip tune it
Thanks for the part on the valve cover bolts. My records show the valve cover gasket was done ~20k miles ago, but I just found a leak and a couple of the bolts could be turned by hand!? I had just changed the CCV system and it was crap. So either they torqued em wrong on install, or they were loosened from the increased pressure like you said. Once again you clear up a strange situation.
Yes mate I’m a expert on this engine as you know mate that’s why a lot of people wouldn’t expect this and expect them to be loose but trust me this is what happens
@@BMWDoctor how do you feel about BMW dealer servicing? I find they are not meticulous and sometimes do sloppy work. I've paid a fortune keeping it BMW Certified by going to the dealer. any suggestions?
Just bought an e92 330i, great information and channel to learn from, thanks!
correct me if i’m wrong but i’m pretty sure 330i is only e90
@@_aveil nope. I also have a e92 330i.
Hey bro I brought a BMW and I was a bit scared when I saw some issues, but your videos give me hope I can repair it even by myself with no experience, I hope we can get this running smooth 👍
Hi dean. I am a international student and studying in Canada. I bought a 2011 328xi three years ago. Now it just hit 100k km. I am planing to change those parts that you mentioned in this video. But I am having a hard time to understand your speech. So can you make a list that could help me to find all the parts easier? and how I can do the engine module update?
0:45 for the engine oil filter components, do you mean need to replace the whole engine oil filter housing parts, not only the cap. is that right?
4:05 do you mean the CCV intake manifold needed to be replaced?
5:00 do you mean the valve cover gasket set need to be replaced? and for these bolts what size i need to get?
2011 N51b30 done two oil changes already with 5w30 just ordered 5w40 🙏🏼 80k 👨🔧 done my oil filter housing gasket, started seeing it fail on the cold starts...bolt behind manifold is not bad just have right tools 🛠
It's not that hard to do all these things. Really good info. The secret of motoring is to concentrate on the weaknesses of whatever you drive. This has been true since the beginning of the car.
Don't forget to change your coolant flange to the aluminum one guys.
Whoa bruh slow down a bit lol.. but do appreciate the knowledge you give. I just picked up a 2010 x3 and .. man... ??.. yeah..didn't know nothing about bimmers and watching your video gives me some ease at what I NEED to know as it didn't start when I got it and now it does... but lack of power when acceleration so still trouble shooting
Thanks for the knowledge again
Great vid. Im in the states, how do you go about updating the modules? Is that something the dealership would do?
I bought a 08 BMW z4 3.0si with 127k on it. It seems everything has been replaced from just looking as for what I can tell. The Valvetronic gasket is the only slight leak it has but I am replacing that this week. I think the Disas have been replaced but not 100% the top caps are green in color if that makes a difference.
That's why im glad for my 330d e46 low milage with m57 engine. Have had other's m57 engine's with 400000 km no problems
love M57 mate trust me but I also love N52 these are good engines also
What do u mean by update the engine?
Doc you need to reply here
Thanks for the video. As one may not have time or money to do or have done the 9 things at once, could you please advice for different operations that could be grouped so that we would end with say 4 or 5 batches ?
Thanks for posting this up. I had to google what running “like a bag of spanners” was. 😝
You sound angry. Like you are about the beat up that BMW.
That’s how I sound always angry ready to fight that’s why that’s how all people who have just come out of prison sound right ???
@@BMWDoctor No, not that. You just sound like you are about to punch that N52 one time, two times, ten times and then burn it down or maybe use rocket launcher to destroy that over engineered piece of crap.
@@BMWDoctor how was prison bro
What were u in prison for
sorry man, maybe is because my understanding in english is not the best, but I couldn’t understand what kind of updates were u talking about at min 3:45 (like a software update? something that they can do at the BMW dealer or what?) thanks in advance
I am wondering the same thing. I hope this get answered.
wondering the same thing, is he just talking about getting a tune?
Thanks for the helpful video, I haven't had to do any of these yet with 50k on the odometre so I will have to suck it up and do them sooner or later
Great video!
I have the problem that my N52 engine has a rough idle only on cold start. Already changed the spark plugs, solenoids, chain strengthener and the twi DISAs on the engine. What else could I replace?
Wish I knew this before I bought one. I have done 6/9 of these. You didn’t mention sump pan gasket. Mine failed around 250,000 Klms but from looking around seem a common failure at around 100,000 miles.
Mate I didn’t in my common leaks
This wasn’t relevant on this video you have to understand aswell this varies country to country is being in the U.K. this is not likely the case here you may see loads of them like that
I have only seen 2 in my time out of 300 so that shows why it wasn’t mentioned
In hot parts of America the plastics and rubbers don't last long. In cooler places they last much longer.
you spoke about upgrading the modules. What model would you recommend and what performance increases would I gain?
Around 100k is when you need to replace the expansion tank, those almost have the exact life span of 100k. It is hell trying to get it seated right, and if yours goes, it sprays everywhere and possible shorts the fan, and a few electric components.
Is it also true to replace transmission fluid around 100k, and BMW Lifetime oil generally refers to 100k?
Bmw lifetime oil is a lie. You always need to make sure to change your transmission oil with new one and the filter as well
Every point you made was what I call ENGINEERED FAILURE POINTS. They are specifically engineered to fail at a specific point to force the owner into the shop for a costly repair. Every auto manufacturer uses them to get into your wallet. All a part of the automotive corporate plan.
Planned Obsolescence at its finest.
@@gtmike916 actually, to me, planned obsolescence is a separate concept; designing a vehicle to look outdated. It will run perfectly, but just look old, enticing the owner to "update" by buying the newest version. Engineered failure is used to force owners to repair items that should last longer if not fail at all. An example is the electric water pump on the BMW. Mechanical water pumps should last well beyond 100K, but you're living on borrowed time after only 50K with the BMW pump. Or the door latch mechanism in a Ford Edge. Some electronic gizmo fails to work after 15k, forcing you to pay well over $700 in labor to replace a $30 part.
Thats normal my friend. Because its not an japanese motor😉
@@abdullahboz7055 If i didn't love the BMW so much, that's what I'd have right now. There's definitely a cultural difference driving that...
Planned obsolescence is a part that is designed in a way that it will no longer serve its purpose after a certain duration or determined wear quantity.
Engineered failure points is not a thing, that’s called engineering for cost vs longevity.
You could upgrade the material and design of every component on the car but there will always be a weakest link, the car would last longer overall but you will always get a part that will fail eventually, it is not only expensive to engineer parts for that, but also pointless if your top 60th percentile of vehicles doesn’t make it to the age at which these over engineered parts would last, they just become heavier landfill.
I have 530xi with same engine with 190000 miles with no issues it’s about how you drive the car 🚗
6. Water pump and the thermostat
a. Replace these. You do not need to change the coolant.
b. Don’t worry about the warm temperature if the car is not overheating.
c. Costs about $50 - $120
Not sure where you're getting your water pump. They're over $600 here
Fair enough "update the engine", but how? What software plz?
Bump
Great Info! Would really like to get your top 9 for the F30 engine. Thank you from Florida.
Hey Dr. Love your video! I’m getting a weird idle on my car. Only on first startup, goes away when it’s been drove for a bit. Do you think it’s VANOS solenoids or Plugs/Coils?
Any update? Have the same issue
They could have put a temperature gauge on the cars. All they had to do was to design the gauge to read normal unless the temperature is out of tolerate according to water pump operation thermostat operation and the coolant temperature itself. All my cars the temperature gauge sits exactly in one spot no matter what. However outside of that parameter it will show a higher reading. You are right I was thinking since the electrical water pump and thermostat came on BMW's they took the coolant gauge off at the same time. So it makes sense.
Hi mate . Maybe a silly quistion but after replacing vanos solenoids you mention updating the modules ...is this the same as an ecu remap or should the actual engine module be replaced ?
Great videos ...learning alot
No mate you update the module using genuine bmw files I have done it for many many many people with success
No remap needed for this and no module needs replacing just updating
@@BMWDoctor ok so is this something I could get done threw you or your company ? If not any recommendations on where . Iv got a 2007 330i e90 Iv had for a couple years currently on 87000 miles and im starting to do some small upgrades and preventative maintenance on as I love the car and want it to run at it's best .
Thanks for any info or advice you give . Best bm vids on TH-cam hands down
@@BMWDoctor how and where do u find these files?
What do you mean updated? Tuned?
Ur videos are always a big help!
thanks bro and im glad they help you guys out thats what im here for right ???
Just bought a 2007 530i with 240k but it runs great. It was maintained really well the car drives and looks loke almost new. What should I keep an eye on at 240k
9 things that fail to you N52 engine... Hold this camera, this engine... 9 parts around here. Thank you.
You have said to update the engine (what do you mean by that)? And if i have the n52 without vanos solenoids can i put them and how to make them work with the ecu
Any chance you know why my oil cap would be leaking after I replaced with genuine part? also rocker cover gasket done by previous owner is now leaking ? Plus my brake pedal goes stiff at 1k revs any ideas on this ? Servo or vacuum pump ?
I have a question about the solenoids I have some issues whit my n52 we did diagnostic and found that 1 of the solenoids is not working the car is lacking power and is slow on the trotile when. i press it hasetate to speed up.
I am waiting for the new solenoid but I wonder is it possible the rataling noise to be from that as well. because it didn't show nothing else on the computer? will be. super thankful for any advice sorry for. my bad english :)
Dr. BMW! I have a question I recently purchased a 2006 Z4 with N52 engine and only has 6k miles on it, kept good and checked engine bay very clean no oil leaks. I've done the oil change and windshield sprayer waterpump. Is any of the 9 points I will need be alarted soon?
The best upgrade on my 2011 X3 with 100k somewhat problem free miles was trading it for a Lexus.... these 9 problems, and several other more was the final straw on a long list of things that cost way more than the car was worth to fix. I also have a 2013 328i F30, with 143k miles on the 4 banger...zero problems, but its not worth two dollars so I just tool around with it until the engine has a catastrophic failure....
Interesting, yeah I have heard that the 328I F 30 is pretty reliable even though it’s forced induction, I am so torn because I love the Bangle era E 60 and I’ve always wanted one, was thinking about getting one as second car but I am also considering a A6 3.2 which is supposedly quite reliable actually. However I do love the F10 five series as well and a 528 I would probably be a reliable right, Of course with a thorough inspection and proper maintenance history
What's that silver looking pipe on the left side of the engine? Mine is open for some reason it doesn't look right but I don't know what it is. Learned loads from your vids tonight though, cheers.
I agree .I have E60 523I 2006 170K miles. Gradually I had to change everything.Still oxygen sensor rear, IBS sensor, oil level sensor and voltage regulator in alternator.
Not sure if anyone has answered this already but how do you update the engine?
What's you feelings in EGR. Would you keep it or get it removed? I got bmw 730d on 2007 plate. It's done 100,000 miles.
Do you think it’s a good first car to learn to work on ? And will it be reliable enough to daily ?
Would you recommend I change everything on this list in one go as I'm nearing the 100k mark? Or am I too paranoid and I should just wait for initial problems to appear?
Hey doc, any advice on changing the transmission fluid on n52 after 100k? was going to change mine it said "lifetime fluid" which doesn't sit right. I've got 160k miles on it!
11:36 queue it up... everything this man says, is proverbs, is TRUTH. Listen to him. Is no lies in these words.
Changed the valve cover gasket, pulley and tensioner at 70K miles in my 2008 E90. Next will be the ABS assembly, I am sending it out to a third party for repair. Thank you.
Thanks for the video! In addition to the tensioner, idler pulley and belt, do you recommend changing the crankshaft pulley/harmonic balancer after oil leaks have been fixed? My understanding is that the rubber in the pulley/balancer can deteriorate after being soaked in oil for a while. Could this part failing be the cause of increased engine vibration at idle? Should you change just the pulley (removing 6 small bolts only) or the pulley plus the backing sleeve thing that is held on with the single bolt? I'm concerned about messing with the timing by removing the whole part with the single bolt.
i'd like to know as well please and thank you,
So when I get a used e91 wagon here shortly. Basically just replace all these things or should I risk it and run the car as is for a short time first?... And if needing to replace all these it wouldn't make sense to pay big dollar on the car just cause it has 70k or less on the clock. When could just pay a lot less for a car with 100k plus on the clock. And use part of the savings to do a bunch of this work yourself possibly. While getting to know the car more when working on it.
exactly the same on my Benz money pits:
Filter housing gasket
Phasers stuck
PCV burning oil
partly developed software
valve cover extra leaks
weak aluminum bolts
serpentine idler and tensioner
....
Serious Ticking come from high pressure direct fuel injectors
last: don't forget to do early drain on transmission oil and brake flush... all engineered for precisely controlled premature failure to help Japanese partner brands
👍
Thanks for that info Doctor!!!
My 06 E90 325i with 55k mileage both valve cover gasket and oil pan gasket starts leaking..The valve cover is easy to work but the oil pan gasket was a pain,It took us 2 days but we managed it.
Excellent video mate keep up the good work 👍Have a good week what do think about the 3cyclinder supercharged mini engine?I was thinking about getting one
mate I havent a clue about them haven't done any research on mini anymore mate as im selling my one mate had enough mate doesn't get the views and the people are ignorant mate who watch cant be bothered will stick to my loyal bmw guys who all support me and care mate
Ok mate no problem I will probably get another bmw anyway no sure which one yet👍
Have an 325ci with the great m54 engine it has now 270000 km on it and runs fine only issue i had is the disa and the timing chain wich beckomes a bit lose
My friend this is about N52 ???? Nobody mentioned M54
Would these actions on an N52 engine be the same for an N51 engine
What's up Doctor Dean. Keep pushing them N52 video.
Don’t you worry young sir I will be indeed
N52 is the doctors game
well I have 2006 530i with N52 (310k km) and the only things I replaced so far was a starter, front spring and connection link on front sway bar. And belt and tensioner at 200k as maintenance, and just standard maintenance stuff, plugs, pads, filters etc. Otherwise no issues, no codes. The only extra things i do is oil changes every 8-10k, and oils in man. transm, and diff, every 80k or so.
Very good
What modules need updating after vanos solenoid replacement? Never heard of this.. Can ISTA do it?
turn key to second position and depress gas pedal 10 times in 15 seconds. i think you repeat it like 3 times in those 15 second intervals
I have a 2011 N52 328i, does you guidance apply to only certain years or all years?
hello doctor, many thanks for all your videos, :) but ! if it's possible in your videos descriptions or commentary can you list pieces your talking about,? it will be more easy for non English people & for translation purpose :)
I get what your saying mate but that is not very easy to do I don’t think any you tubers do that mate as I know TH-cam do provide subtitles if need be
I didn’t think I have non English people watching mate if I’m honest
Hello i just find your channel and i have n52b25 my one have 108k miles i change everything you say apart oil housing and tension with belt... Like you said everything start at around 100k but i sow allot of you videos now and i can see clearly that you know what you talking about is there by any chance you do inspection on other people cars? And if you do where are you base? Would like to bring my one to you for it btw great videos!
Is an N52B25 a good choice? The only reason for not going for 3.0, is `cause in Serbia, registration fees above 2.0 litre engines, especially above 2.5 litre, are very high.
what mileage does this engine start to loose power when should one rebuild, planning on doing e30 swap. Thanks
My ‘07 530i (N52) is at 247,500 and I’m doin just fine! I beat the crap out of it daily too
Come back to me in another year let’s see if you still say that OR you just haven’t checked underneath your bonnet to notice anything but after this video now I showed you I bet you will please make sure you don’t do what the rest do say you have no issues then never come back and report when you do because of embarrassment there is nothing to be ashamed of saying you have issues it’s normal on N52
Looooool. I do my own maintenance, I’ve only had to change the oil, fog bulbs, and cabin filters. The n52 is the most reliable engine I’ve ever had.
So your admitting the car has had problems 😁 as you said you do your own maintenance nobody will ever believe you making a comment like this I have 10k subs and ALL have had problems on there N52
BMW Doctor think whatever you want dude. Oil, fogs, and filters isn’t a problem.
198,000 on mine and only ever did standard servicing...
Hello DR. I have a 09 528i and the ccv diaphragm keeps breaking I replaced it with the quick fix from Amazon because I did not want to change the intire valve cover , unfortunately it only last a week. Does the vanos cause that?
Excellent, as usual. Could you do a similar vid on m57 engine ?
Don’t own the m57 mate anymore and won’t be getting one anytime soon mate wouldn’t want to own one buddy not my cup of tea and also it attracts the U.K. and Eu and sorry mate but the ad money is very very crap from the U.K. and Eu that’s why I try and do videos for the USA base more the diesel was just a one off mate to have the videos here but that’s it mate they didn’t do well and still ain’t money wise I have to favour what gets me the views and big income on TH-cam
Did the N52k suffer water pump problems or did they upgrade with the K variant ? 2009 e60 LCI
Excellent video. Very helpful.
That coolant level is WAY over filled if cold! The stick is pinging the top of reservoir.
Those damned aluminum bolts have caused me so much pain
How much will it to do all these at once any estimate
Dean your a legend.
Forgot the oil pan gasket and water pump. Generally these are pretty solid engines that with basic maintenance will be really reliable. I like them.
I said water pump on this.
also oil pan gasket has been mentioned in my previous videos it wasn't mandatory to do NOW and is not something I consider a major thing on this engine to do immediately it leaks yes but not severely that you cant drive the car.
BMW Doctor Gotcha, makes sense! Good video!
