Hello Mario, I`ve been reading some of your replies on the forums around the S4 mechatronic / pcb issues that afflict s-tronic gearboxes. You seem to be very knowedgeable on the subject. I run a 2010 S4 avant and on a couple of occasions the car has simply shut down. Apologies to contact you this way, but I read so much rubbish on the net and your answers seem to make a lot of sense. Thanks Howard
