Hello everyone, new here and need some help. Got a 20 plate Q2 35 tfsi black edition, lovely car but annoying. The stop/start never works, get the a with a line thru it on dash, apart from this sometimes get the Epc warning light staying on after start up and a stop/start warning. If I turn the engine off and restart all the warnings clear but stop/start still doesn’t work. Had to drive recently with the Epc on but there was no effect on performance. Just had a diagnostic done but the only thing it showed was a fuel pressure fault which was then cleared, driving home the stop/start is still not working. Any ideas where to go next without showering the car in cash ?? Thanks in advance.
