I've got a 2010 A3 2.0Tdi BE (140) I've had the car since the start of September now and the start/stop thing took a while to get used to but it ws great when I got the hang of it, but now it appears not to be working at all. Since probably the start of December anytime I come to a stop the symbol appears saying it is unavailable. The first few times I put it down to the car maybe needing to have warmed up properly before it would kick in but at the weekend I went for along run and still it wouldnt work. Cant seem to see much in the manual regarding it and I made sure that the conditions set in the manual were all met when trying it out again. Anyone else have this sort of problem or am I just doing something stupid?
