Picking up an 2011 A3 TDI black edition on Friday, looking online at information this version only come in start stop according to parkers, When test driving I couldn't see that it is, is there any quick way to check?
Not that it changes anything for me if it has it or not, just be nice to know if all of a sudden the engine just cuts at a sop.
There will be a button on the dash to enable/disable the function. So that's kind of a giveaway if the car has it or not.
It also only functions if certain criteria are met (such as outside temperature, cabin temperature relative to configured climate control temperature, electronic system load, etc). So don't expect it to stop necessarily every time you come to a halt.
