Hello, unfortunately I found no solution for my problem here in the forum. I only read that the circuit does not work at all. But with me the problem is always only if the car stood long. For example, in the morning when I first put in the reverse gear there is a “0” and when I switch to “A” I can only drive the first 2-3 min forward and vice versa if I switch to “A” first then there is a “0” again and I can only switch the first 2-3 minutes to “R” and drive backwards. I hope I have made myself clear. The vehicle is a Smart Fortwo bj. 2000 petrol.
