This is to everyone out there with gear problems and you Smarty:

I recently bought my 545i and noticed that in certain gears the car would "jerk" like all of you; since I am still under warranty I took it to the dealership. They first reset the tranny, it did not work. My boyfriend and I test drove the car with the technician and the shop foreman and duplicated the jerking motion in different drive modes (D, DS & M). We left the car there, got a loaner and told them to call only when the car was fixed! Well, it is fixed and it drives like a dream! THEY REPLACED THE MECHATRONICS MODULE, the invoice reads: "it had faulty shorts for EGS, after replacement of mechatronics I programmed and encoded complete vehicle including CAS. I cleared all adaptations in vehicle and re-teached adaptation values." In other words, they replaced the transmission module.
I just thought that all of you should know what to look for since I was afraid that I had a lemon in my hands...

Good luck

Sorry, just seen your location. Doesn't really help me. Worth knowing but I've always told them it was the gearbox.
The last time I spoke to them about it they wanted to have the car in to clear the gearboxes learning values. However, this would be at my cost and not covered by the warranty as it wasn't a fault as such. Having told me it involves taking the car out and driving it for a couple of hours I declined as I was almost certain it wouldn't solve the problem and I'd be left with a large labour bill.
Catch 22 though as until they did that and ruled it out they wouldn't replace any parts or even do anything else.

Hi Guys, At last someone with same problem, 2005 530d auto all of your probs + misfire at idle after restarting the car after few hours which has been going on for the past two years.
Number of software updates,few injectors changes,change of torque converter had not made much difference, at last service was told by my dealer that it is my driving style causing it,since complaining to BMW customer relations
awaiting another dealer to cure it but nothing been done after four weeks. fingers crossed as trying to drive legally on Dorset roads with occasional juddering drives me mad. Lets find out what can be done to 530d auto together ?
PS: I use a 2001 530d auto estate(e39) for work with over 130K without any problem.

hi my e60 530d is exactly the same,driving me mad ,had allsorts of software upgrades etc,egr cleaned ,filter changes,no good at all, dealer says its fine but its far from it,if i hold throttle just above 1000 revs i get a slight missfire,when i drive at 50 to 60 mph the rev counter is all over the place im quite sure its not gearbox related i just think its deciding wether to change or not with the fluctuating revs,i also tried disconecting maf on mine which slightly improved it but also brought on engine management light have since replaced maf sensor and it wasnt that,im driving mine with maf disconnected now,once its past 2000 revs its like a different car flat spot completely goes lets just hope someone finds a solution,keep trying,garry

Under the acoustic cap you will see the vacuum control system that is used to operate the EGR and the turbo (BMW item 11747796634). These have small airfilters on them used when the system breaks the vacuum..check to see if the filter is dirty..they usually are, clean it and see if the fault goes away. It makes a big difference to the way the car runs..

Mine is finally fixed after 8 months of suffering and 2 months in the shop. Mine was also the Mechtronics module/valve body on the transmission. Here is the part number for the rest of you to demand it get replaced 24-34-7-571-233 (RMFD Mechatronics). It has been bothering me for a while reading these posts and most of the cars are diesels that have this issue but mine and one other was not. All the fixes / excuses offered to you were diesel engine specific and it had to be something common to our cars.

Good luck to all on this.
