N55 eccentric shaft,valvetronic motor

 Ok this is going to be a long post with a lot of pictures,,,,N55 check engine light on,,,,faults were valvetronic motor and valvetronic won’t reach its limit,,,,performed the test plan,,,operated the valvetronic motor test which passed the test twice,,,but when I started the engine it would fail again ,,,,which tells me all these BMW test are not always correct,,,,lol,,,after more testing it finally said the valvetronic motor and the eccentric shaft should be replaced ok,,,,now the fun started. Here you can see I already removed the fuel injectors and the 3 injector and spark plug stands,,,you have to remove them to gain better access to the valvetronic motor,,,,,also notice the oiler line,,,,you should also replace this at the same time.  Here you can see all the injector and spark plug stands removed. Now the fun started,,,during inspection I found the intake camshaft lobes pitted,,,only cylinder 5 and 6 were pitted,,,,we have no idea what caused this or what happened,,,,now are repairs have changed,,,,we are going to replace the valvetronic motor,eccentric shaft,roller rocker arms and eccentric levers. Here the valvetronic motor which is just a worm gear ,,,,,which can move the eccentric shaft very fast.now here is one of BMW over engineered tools needed to remove and install the the eccentric shaft lever springs,,,,you need this tool to perform this job,,,,there is no other way to do this without hurting yourself.,,,even with this tool you can hurt yourself,,,,,there is a lot of tension on those springs. Here is the new intake camshaft and eccentric shaft,,,,you can see the gear on the eccentric shaft which locks into the valvetronic motor.  When replacing the eccentric shaft there are also 6 needle bearing that have to be replace,,,,the needle bearing and the 2 bearing half shell bearing.this I show you replace them,,,,,they are a split open,,,,you carefully spread them open over the eccentric shaft and make sure they spin freely. Here are all the new eccentric shaft levers. When replacing the levers and the roller rocker arms,,,,they all have numbers on them,,,,,so when you order new ones you need to know what the number is in the engine now,,,,the levers and the roller arms are both 02. Here is the roller rocker arm you can see number 2 stamped in it. . Her is the final assembly ,,,what I also forgot to say the vanos gear is removed,,,,because you will be timing the engine,,,,once your done you hope it starts,,,,you also have to perform a teach in for valvetronic motor ,,,,it performs about 50 test without it failing,,,,if it fails you have to start the test all over again.

    Hi guys I am new here. I tried three different Indy mechanics but they cannot able to get my car going 535 n55. I installed new valvetronic motor and new valve gasket. Cleaned fuel injector. Well the car started but with crazy white smoke after three months. I try to teach valvetronic with Foxwell but it does not communicate. I spend lot of time. Any help I’d appreciated .

    • Ok let me get this straight,,,,the valvetronic motor was replaced and now 3 months later you have white smoke,,,,,is that correct?,,,,if that’s correct then it ran ok with the new valvetronic motor with no problems,,,,now after 3 month you have white smoke is this correct

    Hi bmwtech, I was replacing eccentric shaft on my N20 engine first time and installed the oil spray nozzle wrong for the eccentric shaft and motor. Part of the oil spray line was shaved off by the eccentric shaft and left markings on eccentric shaft gear. Do I need to replace the whole shaft or is it okay to keep using it, can you please take a look at my intake and exhaust lobe too. Thanks in advance

    sorry if the same comment was sent previously I don’t see my comment in this post so I’m posting again.

    So I just replaced eccentric shaft actuator on my N20 but I installed the oil spray nozzle for the actuator and gear wrong(part #11377583786), I just removed valve cover to put the nozzle in correct way but part of the nozzle was shaved off by eccentric shaft and left markings on the gear.I would like to know if the eccentric shaft is still useable or do I need to replace whole shaft since there are markings on the gear. Can you please check is the oil spray nozzle installed correctly this time and are the intake and exhaust lobe on my engine looking okay.

    Thanks!

    Hi, 2011 n55 335. Had the woodpecker noise for the last few months, the noise stopped now but getting warnings that engine operating at reduced power and no restart possible. I’ve been able to start the car with no problems and the performance has not gone down but a little rough on hard accelerations.
    I’ve scanned the car with ISTA and have the following two codes:
    2DE3 -valvetronic servomotor,activation, volt phase: line disconnection
    371A – valvetronic, supply voltage: line disconnection

    Looks like the valvetronic motor is dead and I don’t plan on replacing it. Is there any way to turn off the warnings, I have a huge engine light blinking blocking my display of time/temp that’s very annoying!

        I can’t handle this job myself, the quotes I’ve been getting are 2-3K for motor + shaft and I don’t want to put money into this POS. I’ve already gone through two water pumps – exactly at 75K each, power steering pump, both rear calipers seized, oil gasket leaks, etc..

        I also pulled up the following codes, it looks like the system shutdown the motor due to overload for protection.
        036D4 – DME Internal fault, activation Valvetronic: malfunction
        02DE5 – Valvetronic overload protection: servomotor overloaded

    Now here is the full story of my repair so far, Hope no repair in future.

    At the beginning I notice a terrible clicking/ binding noise coming from the engine bay when I lock/unlock the car. Then, occasionally, the engine has hot start problems. It cranks, starts, rough idle and then stalled. No problem with cold start and driving and there is no CEL, but when I pull to the car to the dealer, it shows fault code P1030, which means the Valvetronic Eccentric Shaft Motor has a problem. 

    First repair: I got the eccentric motor replaced at an indie shop, the mechanic said he feels the eccentric shaft is ok when he adjusting manually. After the replacement, the relearn process passed, there is no rapid clicking noise, driving fine, but sometimes a slightly rough idle. 

    Second repair: But just after two weeks, the CEL is on and go to limbo mode sometimes. The Fault Code is 002DCE Valvetronic system: no adjustment possible. The CEL light is on and off. When the mechanic runs the relearn process, it failed. After that, the car goes to limp mode every time it starts. The test plan for the motor passed, but the test plan for the eccentric shaft always fails at the second step. He also updates the DME firmware to the latest version, but the eccentric shaft test plan still fails at the second step. The mechanic then orders the eccentric shaft and bearing, and replace them.

    Third repair: Just after the assembling and starting the car, the car went to the limp mode immediately saying the exhaust camshaft is off timing. He has to open the valve cover again and did the camshaft timing. After this, the car drives fine, but sometimes a slightly rough idle which is very similar after the first repair. But after a short drive, the CEL is on. The faults code is “28A0: throttle valve angle – Intake manifold absolute comparison: pressure too high”. He checked all vacuum lines, pressure switches, and MAF sensors. The smoke test passed too. Nothing is wrong. The CEL light is always on after erasing it and doing a test drive. We are really frustrated and decide to accept the fact. 

    But when I pick up the car after a short test drive, the CEL is off magically! I drove the car for several trips locally and highway for two days, the CEL is still off. Based on your experience, can you make a guess about what happens for the “28A0” fault code? Thanks.

        Thanks for your reply, even when I clear I can’t do the learning procedure, the code stays there. even if the code is not there immediately if I try to do the learning it will tell me that values for the test are not met and that theres a valvetronic fault that need to be fixed. for now im waiting delivery of an eccentric shaft and I will put a new servomotor as well, as for the charging pressure too low I was thinking maybe my wastegate actuator and I checked it and its not stuck or anything it all seems fine. I think I will also look for the boost solenoid valve and maybe it would help. tell me what you think and what should I do if I change eccentric shaft and servomotor and still can’t do the learning phase in that case it would mean my DME need a reflash or repair? I read online that sometimes the 2011 models like mine had these issues caused by the software in the DME and sometimes need to update it ? how could I do this update myself or what do you suggest ? thank you in advance you have been really helpful!

      • Ok first thing your turbo boost charge might be related to the valvetronic motor issue fault,,,,so fix that problem first and see if the charge fault goes away,,,,now yes you can update the DME software but you need someone who has the technology and software to perform that task.

        also my car sound like really bad when idling but when gas is pressed its not making the strange noise, heres a video https://www.youtube.com/watch?v=CDubb7FCAgk

        please tell me what this could be ? thank you ( im thinking misfires due to the valvetronic problems since the valves are stuck in a open position or something like that)

    Hi, got the P1030 code on different OBD2 app and 133E10 on carly. I don’t have the click noise some people mention happening when you unlock car. I have a mild to rough idle, nothing crazy as if it is misfiring. Car drivers fine no performance loss. 2015 bmw 335i xdrive, 50k miles.

    Few weeks ago I replaced spark plugs to NGK one step colder plugs gapped at .022. I noticed some oil in spark plug wells, someone who I thought they knew there stuff, but I am thinking that maybe I have a bad VCG, would this cause my issues? Or is it the VVT and Eccentric shaft, really wishing its not, don’t want to dish out 3-4k on it. I am currently getting ISTA+ to see if I can get more precise codes. Thanks for any help.

    • Yes the oil in the spark plug holes is from your valve cover gasket leaking and no that is not your problem,,,unless the oil damaged the ignition coil when it was sitting in that oil,,,then maybe that will cause a rough running issue,,,,but it still could be your VVT.

        Okay, so I had a tune on the car, and I returned to stock tune, and unfortunately it looks like things got worse lol… Now, the rough idling is gone, but during warmup it seems like its slightly idling higher, but once the exhaust valve opens, it goes to the line just above the 500 rpm mark, and doesn’t seem to be rough idling. Unfortunately it did stall out on me a few times now and the drivetrain malfunction popped up.

        I read that there is usually a clicking noise before turning the car on, basically when you unlock the car, I don’t have that. Here is a list of codes from Carly App, 134A02, 135302, INFO 135704, INFO 135502, INFO 21A000. Could I be having these errors due to a bad battery? MY battery is 6 years old the original battery. I wrote 2015 that was a mistake, I meant to write 2014, built in March of 2014, so battery is 6 years old.

        Thank you for any help in advance! I really appreciate it.

        Haha, sorry I forgot to mention in first post. No piggyback, upgraded aluminum charge pipe, a bigger intercooler, upgraded air intake and catless downpipe. I had a bootmod3 tune on it which I have since taken off and am currently on the stock tune. I checked the battery voltage using Carly last night, it appeared to be in normal range, about 11 when car is in on position and steady at 15.0 when car is turned completely on. So since returning to stock tune, I haven’t had any issues. I took it for a little drive last night, and car never stalled, no rough idle, no other symptoms car drove like it normally did. Drove as if nothing was wrong. First thing tomorrow will purchase a new battery from BMW and install, they are closed today.

        Are there any symptoms of a bad VVT and/or eccentric shaft?

    • Ok,,,first thing to do is make sure your battery is in good condition if it is 4yr old it might be time to replace due to those voltage malfunction and volt phase faults,,,,then if you can have some one run a valvetronic test plan and see if the valvetronic is operational,,,,I wouldn’t be surprised if you will need to replace the valvetronic motor to start,,,also maybe the valvetronic motor and eccentric shaft,,,,I hate to tell you these valvetronic faults can get very expensive due to its hard to say exactly what’s going to fix the problem,,,,sometimes it’s a process of elimination.

    I had replaced the battery 3 months ago but with a regular non agm battery, I believe H7 or H8 as typical with BMW. The Foxwell 410 reads the 133e10 code as a “permanent code” and I am unable to clear it using the foxwell. Every time I do a DME engine scan, this is the only code that shows up, no other code and there is no check engine or any indication, only the scan reveals this.

    Thanks very much for following up.

        So I reran the valvetronic phase in relearn for 20 mins and could hear the motor clicking and cycling through its 450 cycles and then it does an additional 50 cycles to test the calibration results and it passed, then reran the valve stop limits and voila, the code has finally disappeared and is no longer in the DME.

        Not sure what to make of it but I guess Ill keep an eye on it. I just changed the oil 100 miles ago and noticed I was 1.5 quarts down, I am not sure if this could have somehow limited lubrication to the unit but I cant explain it.

    Hi BMWTechnician,

    I had a generator failure due to which the accu was drained totally. During this time I heard a rattling sound from the right front at every single door opening (I mean pressing the FOB to open the doors). Due to the direction of the sound I had a feeling that it was the valvetronic system but that time I didn’t had any device to check and I was in believe that this happened because of the insufficient power from the accu. The depleted accu finally resulted an emergency stop right before I could get to the shop.

    Replacing the generator made the sound disappeared immediately. However in the gauge cluster I still receiving different messages as ‘drive moderate’ or ‘after engine stop I won’t be able to start the engine again’ which I saw first time when I had the emergency stop.

    I have bought Carly and checked the engine errors and got the following codes: 133010 – servomotor malfunction, 133011 – supply voltage malfunction, 1F0515 – supply voltage line brake.
    Now not sure if I have servomotor issue or just need to check the supply cable and related electronics.
    Could you please let me know what you think about this?
    Apart this the engine runs fine not experiencing any issues with the car.

    Regards

    • Ok first thing I would do see if the fault will clear and see if it comes back,,,,now if it comes back you can check the connection at the valvetronic motor and make sure it is plugged in and that no oil is inside the connector,,,,then I would perform the valvetronic teach in procedure to see if the valvetronic motor is good or if you really have a bad valvetronic motor.

        The connector on the top of the engine was unpluged and reconnected as this was my second guess. No oil inside but will check again. For sure it was not noticeable at first glance so I assume there is no oil.

        I have made the check on the engine with prof. tool and it showed the same results what I’ve already stated before: some electricity problem for the Valvetronic. Scheduled a shop time to measure out the cable or if it will be possible to swap the cable with another to see if this change the behavior.
        I am still wondering that can it be the generator causing the issue what I’ve swapped recently or there is no way for sor such side effect? Note that I still receiving error messages that after engine stop I won’t be able to start the engine again. This is due the reason that the generator somehow kicks only after the first rev of the engine. After this gives the proper voltage. The generator I’ve put in is the exact same model as it was before. (no clue why it is not providing the voltage immediately) The only thing that it was renewed and not brand new.

      • That could be a issue with the generator,,,or is your battery in good condition,,,,because the valvetronic want voltage during start up,,,,now that being said the generator does take some time to supply voltage because the generator doesn’t alway supply voltage when idling because it is voltage sensitive,,,it will send voltage when needed.

        I am still struggling with this issue. It appears that the Integrated Power Supply Module (Z11) does not give out the 12V toward the Engine Control Unit. On the input i have 12V while on the connector which supply the power for the Valvetronic port of the ECU is dead.
        Ok bought a new Z11 Integrated supply distribution modul but the issue is the same.
        It appears that the ECU must provide power too to the Z11 and then only the 12V will appear back to the ECU which subsequently will provide power to the actuator of the valves. Funny right?
        So my question how can I know to avoid further unnecessary purchases that say the actuator (valve motor) is working or not? Can I measure a resistance between the power and ground port of the motor too see if it is ok? How can be assured that because the actuator is down it probably broke the part of the ECU which is dealing with the valvetronic? Also it is strange that even though the valvetronic is down the engine works perfectly. No noticable issues so far just the annoying error notices on the LCD. Let me now how can I check the that actuator motor is ok or not.
