    I've had my s3 for 6 years, so I'm familiar with most of the little problems. The engine generally runs ok, although there is a fueling problem. My mechanic has run a couple diags', which shows nothing. However, it's just failed the mot with a high co2 level at fast idle.

    Any suggestions?

    I Havn't got a vagcom reading...my mechanic uses snapon software, which doesn't indicate much. I'm hoping to contact Kev and get a vagcom reading.
