Help! The engine management light on the dash on my A3 TQ has just lit up for no apparent reason. I rang Audi Assist and they advised that so long as the car seemed normal (which it does) then I could safely finish my journey provided I pulled over the moment anything seemed amiss (so far so good) and that I should take it to a dealer asap. So it's off to Docklands tomorrow. Anyone have any idea what might cause this? It's only been 7 months and 5k miles since the last service (car's done just under 43k) and everything seems pretty normal otherwise.
