Had my A4 for around 2 years now. Has been great to own and I was just thinking the other day never had any majr problems with it! It drinks oil a bit but I have heard thats normal on 2.0T especially when you floor it!

Anyway - Last night the engine light came on.....I dont think its coil packs (like the old MK4 Golf 1.8T used to) could it be the emissions sensor? Whats a common reason for the engine light to come on?

The car has FSH from audi - recently had a big service dones aswell!!
