Hi guys, Have only had my S3 for 2 weeks. All was fine for the first week, but I noticed on Friday morning that the car seemed a little lumpy on tickover when I started it - I put it down to it not having been used for a couple of days & having done a couple of short journeys (<10 miles) the week before. Today I had to do a 35 mile round trip for work and on my way out (about a mile from my destination) the emissions control system light flashed on & off a couple of times, but then stopped. Had my meeting, returned to the car about an hour or so later & when I started the car, the emissions control system light came on & stayed on Quickly opened the manual before I set off & googled it / searched on here & then drove very carefully, very slowly the whole way home to be on the safe side. My searches seemed to bring up a lot of diesels who've had problems involving the emissions light, but I could only find one S3 with the issue reported. Any of you guys had any problems involving this? The car came with a 3 month warranty via one of the warranty companies, so going to ring the dealer I bought the car from in the morning (120 miles away) & then book it into a local garage - I'm hoping I'll be allowed to use the local Audi dealer?
