Hi, I drive a Smart 451 1.0 Turbo. If I go to the small one, this loses the gear position from time to time. After I do a manual reset, the Smart is in the gear emergency, I can only use gear 2.3 and 4 and that is not so right. The funny thing is, if I do a basic setting with the tester, it works again for a few days, but then again three beams and the gear position is gone. In the FS there is only one CAN error C1323. I hope one of you can give me a hint.
