The car's gone in again today. I've had it about two months (it's an '03 S3) and the week after I got it the battery died. Today's visit back to Mr Audi is because the Traction Control and ABS lights are on permanently, the radio stopped working (may not be warranty) and when I close the drivers door, it makes a crashing noise which sounds like there's a large metal panel inside which is probably loose.

Ho hum, hopefully it'll all be mended when I get it back.
