I don't have a B7,but asking this question on my friends behalf
,he bought a B7,2012 Model,with 188,000 Km on the clock,it got Start/Stop system on,the problem is that this feature don't work all the time,it might work once or twice a day,and sometimes it don't work at all no matter what,the temp. is 90,seat belt on for driver,and passenger ,and still no joy,so what would be wrong,got checked with VAG,and no faults at all.So please let me know what you think,if we are missing a thing,thank you.
