Hello dear motor-talk-community, our fat guy has been spinning around for some time and I can’t get any further. When unlocking the car, the throttle flap starts to clack in the front, if you want to start the car, a complete Christmas tree lights up in Tacho. The flap clacks further. Various error messages are brought: driving stability failed, drive disturbed, parking brake loosen, RPA failed etc. etc. I turn off the ignition and wait until the flap stops klac kern, are sometimes 5 minutes, sometimes it can only be started after 20 minutes, after which all error messages are also gone and everything runs normal. Shutter was changed test-wise and learned, error was still present. New AGM battery was also installed. ISTA shows the following error (unfortunately not in the possibility to upload pictures): CA940A: message (data, powertrain 2, 0x3F9) missing S 0237: No communication possible with: Electronic fuel pump stu CF1501: Message (N47 with great consequences) is missing, receiver EGS, transmitter DME/DDE… CF1511: Message (N47 with great consequences) is missing, receiver EGS, transmitter DME/DDE….

I discovered a similar article here:https://www.motor-talk.de/…/…-schief-fahrkomfort-weg-t7085999.html Unfortunately I can’t mark the contributor, he got great answers. WO start looking? The workshop has already checked cable trees and checked fuses.. i ve What can I look at as a hobby screwdriver?
