Really appreciate you making this video. I had to do it on a friends X3 with the N20 engine, and this really helped a lot. It wasn't as hard as I thought it was going to be, and honestly the hardest part was just getting to the the Valvetronic motor by taking the valve cover off.
great video, one hint to make it simpler: you only need to remove the front bucket, the actuator comes out with the back bucket in place. Also you only need to remove the back injector to remove each bucket so in this case to do the whole job you only need to remove one injector (#2 cylinder injector) cheers!
wow great to know!
Hello looking to perform this on my vehicle do you have a video showing what you mean ?
@@VTI2CLN my comment was for a n55 motor... I don't really know about a n20... no video but if you perform the top video you will see if you need to take the back bucket off. For me I only had to twist the actuator off
I just successfully completed the job today. Thanks for the great video.
Its awesome to see how many people find the video useful and save $$$
Any info on the injector seals?
What issues did you have?
Mine is being a pain starting and when it does not can’t get any revs or power and it will rev to 1500rpm then it will idle at 500 and stall!
@@TS-ji1me I just put the injectors back and with original seals. Had no issues
@@jimbojacksonmurray9841 perfect, that will save me a lot of hassle.
Can I ask what issues you had with the valvetronic?
I’ve had random clicking coming from it, sometimes warm restart issues where it rough idle or stalls, and now today I’ve lost all power, rough idle, stalling and won’t rev past 1500rpm. If you put it in D or R it goes to 500rpm and stalls.
I have no fault codes either. I’ve got videos up on my account.
Beyond a nightmare as the car is unusual now
@@TS-ji1me I had no other symptoms. Just the loud clicking when I unlocked the doors. I also had the typical valve cover leak
Спасибо друг , ты очень поправил мое положение по вальватронику замены . 🙌
Бесконечно благодарен тебе , жму руку 🤝
If I may, I just did this exact job today. On the N20 4 cylinder engine, you have to remove the Number 1 and number 4 cylinder injectors and both injector buckets/housings have to be removed. You do not have to remove all of the injectors. Be sure to return the same injector in the same cylinder that it came out of. Each injector is calibrated to its cylinder. You cannot get the servo motor out without removing both housings. The next part that I didn't understand was how if the eccentric shaft was spring loaded, how could you leave it in the maximum position without it springing back? As it turns out, you will find that on both the minimum and maximum positions, the shaft goes "over center" and the spring pressure is released. When the shaft moves off of either of those positions, the spring tension takes over. As you are turning the allen wrench on the servo motor to the maximum position, you will feel the eccentric shaft sort of "roll over" to a position where it has no tension. When you reach the maximum position, there isn't any spring tension on the motor so the shaft stays in its maximum position until the servo motor moves it away from this position. I hope this helps explain how PANDYDIY did this repair.
What are the symptoms of bad eccentric shaft sensor
Please help
Great explantion. Mine is a N20 engine too, what are the symptoms of a faulty valvetronic servo motor? Thanks
You made this really easy to understand all n around, thanks! My brother just bought X5 and his idle randomly gets really rough and then the car goes into safe mode & it Won’t leave it unless I use my scanner. I’m pretty sure this is the issue, Is it always best to replace the servo motor, needle pin bearings, etc? It looks like you just replaced just the motorized work gear motor itself... This makes me appreciate my little E46 & it’s simplicity a lot lol
Since my issue was just the servo motor itself then I ended up only working on that. I really try avoid anything BMW related since they atleast at my point of view are over engineered. I would prefer to stick with older N52 INLINE 6 engines and older since they seemed to be more reliable and little less complicated.
А зачем его менять? Если вальветроник начал плохо работать, значит там выработка на шлицах вала и моторчика, менять нужно и вал тогда. Просто сменить моторчик проблем не решит.
This is exactly what I needed. Thank you!
Thanks for the video. My f30 has the valvetronic code and the acceleration is very very slow. Dealership said to replace valvetronic. This will fix the acceleration problem correct? Car shows drivetrain malfunction
The amount of views this video has gotten is just a proof how common is servomotor failure on these engines. You might want to scan fault codes and google them to see whats the cause of these causes before start spending money on amy part. But if dealership said servomotor then I'd assume they know what they talking about.
I have the same issue and you and other codes with it, but drivetrain malfunction and everything
Did you end up fixing it?
How can we be sure if the valvetronic motor is bad before we replace it?
Thank you Well Done
Great video thank you
Great video thanks so much. you did a great job.
Thank you for watching and leaving a positive comment !
@@pandydiy I need to perform this job on a customer's car and besides for the pain in the ass valve cover to get off it doesn't look like its that hard to change the actuator
Nice good job with disruption 👍
Hi, thanks for the video. I've been trying to do the relearn procedure on my E91 with the N55 engine and, before the procedure starts, I am getting the error "Fault: Voltage supply". Any idea why? Or what voltage supply is it referring to? The car was on a wall jumper and had a constant 13.9 volts as shown by the DME. Thanks!
P.S. For extra context, I am trying to fix an "2DCF Valvetronic system: No movement detected" error. Car runs fine, pulls fine, gets good gas millage and just has this error there that is always current and can not be deleted. Actuator was changed, wiring was checked, eccentric shaft looked good, no visual damage and moved freely.
I have similar problems did you ever figure it out I have a 2012 x5. Let me know if you figure it out.
Great video!!!
This exact thing happened to me and I’m about to try and fix it myself on me 2013 BMW 328i. The codes I got are 134F02 and 135B11. Are these similar codes you got???
mi BMW 335Ino arranca me dice el escaner que hay fallo en la valvetronic, tiene marcha pero como si estuviera ahogado, crees que hay que cambiar la valvetronic?
my BMW 335Ino starts the scanner tells me that there is a fault in the valvetronic, it has gear but as if it were drowned, do you think the valvetronic should be changed?
Thanks brother its helpfull
Does have to be on the maximum stroke position???
Would this cause the car just to crank and not start
Im pretty sure it will, i have a BMW X1 with that problem and im pretty sure that is the valvetronic servo
Good one bro
what is the torques spec for the bolt to hold valvetronic together?
Thx bro👍
What would happen if you don’t put the Eccentric shaft back to the open position before you complete the job? I recently had this job done and I’m experiencing issues. Any help would be appreciated.
Not sure, maybe you need to relearn max and minimum stop for shaft, I unfortunately dont have a answer for that
Would that cost a low compression issue n20 engine I just replace my injector now I have a no start
No it definitely would not cause low compression issue, scan for codes and find out why you have no start. Not sure how injectors are on these, if they need coding or not
@@pandydiy it started with a misfire 1-3-4 replace injector did the coding and after car didn’t wanted to start check for spark ok fuel ok check compression low 1-3-4 90 psi num2 119 psi add oil on 4 cylinder compression jump to 160psi I’m thinking piston ring what else can cost a no compression out of timing ?any tips
Hi, when you did this job did you put new seals on the injector?
When you reset the setting, was that while running or when engine was off?
Thanks
I didnt replace seals on injectors , resetting/relearn with engine off first and it should tell you to start car etc, diagnostic tool should give you exact instructions how to follow thru the process
New servomotor teach in proccess is done with engine running, your diagnostic tool should give you step by step instructions.
@@pandydiy hey there, everything still good with the new servomotor? Did you need a new eccentric shaft untill now?
@@catalin.c i sold the car little after doing the repairs, so I unfortunately would have a answer but Im sure it worked fine, original part and correct replacement procedure and relearn, should be anything wrong unless something else is wrong
I think mine was on the opposite side
Do you have to have the scan tool to reprogram? Options if you don't have one? I looked up the tool you have and it is quite expensive. Thank you in advance
Unfortunately to teach in your new servomotor then you'd need a diagnostic tool which is capable doing so.
@@pandydiy what did u use?
In which menu is the start up valvetronic process? I have the MK906BT and I can't find the option to do the process on an N20 engine. Thanks
You should find it under engine management menu / ECU and check ACTIVE TEST OR SPECIAL FUNCTIONS menu, sometimes even before going to all the menues you have a TAB for SERVICE or HOT FUNCTIONS
@@pandydiy Thanks. Just to confirm, battery was disconnected as well prior to stripping the intake?
You can disconnect battery for sure, in case you didnt no big deal, you just have to clear all error codes that appeared when battery was connected and connectors was disconnected
@@pandydiy Thank you for your help
hello, I wanted to ask you can I drive my car after changing the servomotor but not having programmed it because I can't program it?
Unfortunately i wouldn't know, you probably can drive it to the shop nice and easy but i wouldn't recommending to drive without getting it calibrated. If not getting it calibrated then why even do the work and spend money 🙃
@@pandydiy so in fact I changed my servomotor but I can't program it the new one with the same reference but used comes from an x3 N20 motor it tells me that the motor is not at 0 or the servomotor is dead is put in degraded mode, and i want go bmw concession for he change or program
Great video, super informative
Great you found it useful :)
Hi can you tell me what model of scanner do you use for this procedure?
Autel maxisys ms906
Have the number 906 any additional letter like TS, CV or Pro, because there are 4 differents models and I want to be sure if the more basic (MS906) works for the job
@@rafaeltorres990 mine is just MS906
When i unlock my door theres a clicking noise and sometimes rough idle. I bought the same part in video (come from turkey too) but before i take it to a garage i would like to know rough labour costs. One garage said itll be £45 plus vat and another said £160 so not sure whats the price please help. Its a 2013 m135i
In USA FL I was quoted $550 dollars , if you can get it replaced for 45 british pounds I would definitely let them do it.
PANDYDIY thank you for your quick reply. Its weird because car was mint before i had a full front end accident. Ever since that this come up. Mileage only 46k and code was 135808. I definitely will take to them for £45, hopefully not £450 lol
@@thecourier9269 hahah, yes I hope that you are not missing a zero.from the numbe
What was the labour cost in the end, also in UK too
Hello, I had my mechanic install the eccentric motor but it does not allow me to go through the reset cycle with the same scanner. Would you be able to help me out?
Hey Sam, if you follow the instructions on the scanner then it should get everything relearned as my scanner did.
@@pandydiy Hey Pandydiy, thank you for letting me know. Apparently, my car would not allow the scanner to go through the processes. It keeps throwing errors and quits on my mechanic.
@@samlee9245 what kind of errors, maybe he didnt do the job correctly ? Just guessing , if all the steps are followed and the part was installed correctly then it should work, is there other codes that its giving you ?
@@pandydiy I'll confirm once I visit my mechanic tomorrow! Thank you.
@@samlee9245 there might be some trouble codes which may affect the relearn process
What trouble codes were stored in the PCM or what were the symptoms before the valvetronic actuator was replaced? I got a no start condition on a 2013 BMW 328xi N20 with a lot a trouble codes stored, I cleared the codes and the
133E10 Valvetronic System Deactivated, Excessive Adjustment Error does not clear, and still crank but wont start.

Are you sure your timing has not jumped ? Its pretty common problem on those engines to jump timing due to tensioner or chain guide failure and that would definitely cause no start condition, you can perform a compression test to see if you have compression in cylinders, they should not much different from each other no more than 15psi difference Id say.
Thank you for your reply. I'm waiting for an spark plug socket to remove the spark plugs and perform a compression waveform analysis to check for a timing chain out of time.
@@victor.flores8849 have you found out your issue? I have all those same codes
