[QUOTE="yoko9798, post: 637373, member: 23344"] Hi guys, Just wanna update all of you on this issue. FYI, I may have the solution for this prb. Search the internet and have tried below steps and surprisingly, so far so good!!!! It maybe an interim solution but in my view, its worth the try. I have been to a couple of workshops and both has basically asked me to let them to service the solenoid and even then, they said that it may not be 100% the solution since code wise etc, they cannot find any error to my e92. Anyway, while surfing the net last week, I found out that, it may just be the Adaptive Driver Memory that needs to be resetted. I have resetted it and the jerks is now gone........(so far). Steps as below (quote from Bimmerfest site): " Resetting the Adaptive Driver Memory for the Automatic Transmission -------------------------------------------------------------------------------- Over time the ECU in the trans learns your driving style and that is what it keeps in memory. The throttle is "Drive By Wire" and adapts and personalizes to your particular driving style. However, there is a way to set the ECU back to factory default. I have done this with my 07 328 and it works fine. I've done this with several Mercedes. The only difference with a push button to start/stop engine system is that you must use the start button instead of turning the key to it's first position and again to simulate the off position. DO NOT REMOVE THE KEY DURING THIS PROCEDURE Here it is; How to do a TBA: Throttle Body Adaptation reset. Resetting the Adaptive Driver Memory for the transmission. Works with any car that has Driver Adaptive Electronic Controlled Transmission. 1. Get in your car, it doesn't matter if you close the door or not. 2. Turn the key to the on (not start) position, the position just before the starter turns over. BMW: press start button – foot off brake - all idiot lights on. 3. Press the gas pedal to the floor with the key in the "on" position. BMW: All idiot lights on. 4. Hold the pedal to the floor for five seconds, then turn the key back to the "off position". BMW: foot off brake press start button - all idiot lights now off (don't remove the key), then release the gas pedal. 5. Wait a full 2 minutes for a full electronic alignment. Don't remove the key. 6. Start engine, drive the car, notice the difference." Cheers guys. [/QUOTE]
