HI ZUSAMMEN, after a long consideration I decided to look for help for my patient BMW 730d 2006 bj in the forum. It started with a jerking during the ride and ended with a complete overhaul of the gearbox this was made the jerking was standing so we have made the differential, distributor gearbox plus seals bearings also new however this is beating what occurs after about 30min driving as soon as the transmission oil is warm. after all the repair I made a deep diagnosis and found that the gear control unit has no contact like other 10 things I read on DDE EGS DSC SIM MOST ARS CIM PM WIM TMFA WZBF TMFAH PDC HKL SMFA what I understand but just ned the car is running it’s going great switches well up to what happens after 30min I know just ned more try to check the electronics somehow first checked the battery with running motor we are at 14.70v and turned off engine we are at 12.25 tomorrow morning fair before I start again and see how much he has then. my question would have been known by someone who had had this problem someone who can’t get it all recorded but still the car is running and not shown in the board system I apologize now already for because giant text am new here.
