Hello Now, since we have the car, it has been the second time that the car has been stuck in a gear while driving. It no longer switches up and no longer down, even with the buttons behind the steering wheel, nothing changes. The only thing that helps, stop, engine off, key out, start again, restart and it goes again. I have read in other forums that this happens more often with the 7G transmission and the control unit, or a sensor there. so far so good, only I have an invoice from January 2023 where exactly this unit was exchanged, including the transmission oil – can that be that it is not possible now? Or does something have to be re-learned? I was recently with Mercedes and they have read out errors – there was also no fault of the transmission deposited. What would you do? The workshop, which did this, I can hardly ask, because that was paid for by the previous owner and it appears d, a few months at least, worked. Thank you.
