Just a quick question. Is there any problem washing my S3 S-Tronic in an automatic tunnel with that kind of drum conveyor belt that push your car forward through the tunnel pushing on the back of the tire?
I read on the instruction manual that the car be towed in Neutral position only for a brief amount of time.
So my question is:
If it is possible does the engine must be left running? On my BMW RWD and automatic transmission (torque converter) I put the gearbox in neutral and switched off the engine. Is the same here?
