Hello together, now at the beginning of the season I got above all SL out of the garage. Season marking 4-11, wintered in underground garage. Car starts with half full battery. I drive closed into the sunshine and drive the car warm to open the cover at the next parking lot. Everything normal. The gearbox switches soft and normal high. Then stopped I opened the cover with running engine and gear position P. Everything worked wonderfully. I set on R (it jerked merkl I), park off, switch to D (it jerked noticeably) and drive off. Only the gearbox doesn’t turn up anymore! What the hell is there??? Well, it will be the emergency program! Had I been to transmission service before last year. There I read out the fault memory and had transmission flushing done. There were 2 errors stored. 1x something like torque monitoring addressed and another. Everything got back. Then everything went butter-soft! Now my Fra ge: What happened to jump out of the blue into the supposed emergency program? What can I do? Can I delete the error memory without the appropriate equipment? Oh yes, maybe this is the reason: the battery was 2x flat over winter. I got it only half full at 48h! Greeting Klaus
