Occasionally (1 in 5 stops roughly), whilest sitting at, say traffic lights, my a3 will rev itself between its idle point and about 1.5k revs up and down until I pull away.
Engine management light is on.
Unfortunately I have not had a chance to get it diagnosed yet due to a busy work schedule but I would like to know what you guys think the problem maybe and a rough cost if at all possible!
Thank you
