The BMW 335 rattles when accelerating

Strong jerking when accelerating with the E92 335i

  • Hello,

    a friend of mine has a serial 335i built 05/07 with approx. 53,000 km.

    About 4 weeks ago the vehicle began to jerk heavily when accelerating.
    This problem does not occur when idling or at constant speed, only when accelerating.

    The vehicle does not produce any error messages and has also not stored any errors in the memory.

    The coupe has now been in the BMW workshop for almost 4 weeks and the following parts have already been replaced after consultation with BMW headquarters.
    - 6x spark plugs
    - 6x ignition coils
    - 6x injection nozzles
    - High pressure pump
    - camshaft sensor
    - Camshaft bearing (was not the cause either, but 1 bearing already had very strong scoring and was extremely leaked. )
    - camshaft
    - Flywheel

    The engine control unit was checked several times by BMW and found to be error-free, a measuring device from Munich was also connected to the vehicle in order to read out data while driving, which was then sent to Munich, all without result.

    Both BMW and the workshop now no longer know what to do and no longer have a solution in stock.

    So here's my question, has anyone here ever had this problem or has heard of it, e.g. in a circle of friends, forums, etc. ??

    I would have guessed that it comes from the boost pressure control or something similar. However, it is astonishing that even BMW cannot find the fault. In such a case, can't the car be changed?

  • In this case it is a leasing vehicle.
    If the error is really no longer found, this will be the next step, whether it is conversion, termination of the lease or something else, no idea.

  • Which workshop were you in? I don't mean the name now, but in which city and was it a dealer or a NL?

    It is a BMW dealership (dealer) in the Rottweiler area, I myself have been a very satisfied customer there for about 15 years and I express a very high level of competence to the mechanics and masters employed there.

    All repair attempts were always made according to instructions from BMW in Munich, since no error message was issued from the start and everything is within the scope of the guarantee.

  • Hello, I also had the problem a few weeks ago, but an error message was stored in the memory, it was about fluctuating boost pressure. First, the HP pump was also replaced, and the error reappeared.
    Had reported about it some time ago. Now the wastegates or something like that have been swapped, the car starts running like hell, takes the gas much more spontaneously and there were no more problems. Maybe that would be a starting point for the workshop. By the way, my 335 i is built in 04/2007 and has 43,000 km on the clock, that could actually have been the same series production. Good luck finding mistakes Joachim Stürmer

  • The wastegates were exchanged, as with you, at approx. 40,000 km, the error message back then was "boost pressure too low".

  • Mmmh, then I would push for a change in the vehicle, after all, very, very dangerous situations can arise, as was the case with me. In any case, I wish you the best of luck with this. LG Joachim

  • Had a similar problem, which I also described in the "Nölle" thread. No errors in memory, performance degradation when accelerating.
    It was the pressure transducer that got stuck. I changed it on my own suspicion, because I no longer have a guarantee anyway.
    I saw in the list that it has not yet been changed. Try it with the ..... It changed in 5-10 minutes.

    Thank you, I'll pass it on in a moment.

  • Just as a little update.

    The fault was not found after about 8 weeks in the dealership and exchanging countless parts, now the vehicle has been at BMW in Munich for 3 weeks and the fault has still not been found.

    Redrum: what's newer?

    AlpinaB8 4.6: What do you mean by "seen in the list"?

  • By list he means the list in my opening post of the parts that have been replaced.
    By the way, a lot more was exchanged, pure material value according to the workshop, approx. 15,000 euros

    The vehicle is now being converted.

    I hope that the creator of the thread is still present

    I've had the same problem for a while.
    BMW has also changed parts for about 6000Eur.

    The point with me, however, is that said problem is only between
    2300rpm - 3200rpm occurs. It is also the worst
    In 6 gear (manually shifted). In the 5th and 4th it is still very present but
    Not as bad as in the 6th, and only half as bad in the 3rd.
    I don't notice anything in the first and second gear.
    And as I said, from 3200 tours everything is fine.

    The worst is to accelerate the Autobahn 6 gear at 3000rpm (since about 130)
    How was that known to you at Dirk?

  • A few more details:
    My car
    E92 335i Coupe 8/07
    Km stood when it all started: 90,000
    BMW has already changed:
    All spark plugs
    All injectors
    All ignition coils
    High pressure petrol pump
    Latest updates for the control unit
    Also vofde after the pump brim control unit
    Reset so that the system "learns" again.
    After the pump it got better, but not for long.

    The workshop manager at meimen said after further training
    That other could solve my problem by
    You would have replaced EVERYTHING together. For me everything was done one after the other.
