Hey All - my emission control system light has come on and stayed static for approx 15 miles. I have a 2013 Q3 and it's done 50k miles. Just wondering if anyone knows if it is still OK to drive the car normally whilst this light is on? I've just been to Audi and they can't get to look at it until next week and I need to use the car every day until then. What does the warning light even mean? I know it needs a diagnostic check to find out for certain, but in general? Also wondering if an independent garage might be able to fix it, for cheaper than Audi direct? Any help appreciated please. Thanks.
