Traction control / ASR warning light after battery change


Registered User
Hi guys. Hope you're all having a good weekend.

I eventually found time today to put my battery on my B6 A4. After a bit of faffing and fiddling, it was done and, luckily, all electrics (radio, central locking etc) worked fine.

However, I now have a dashboard warning light on, and having done a quick read, it appears it's the Traction Control warning. It's an exclamation mark, inside a triangle, inside a circle.

Anyone advise me about this light, and how to reset?

As above. You may have to drive around the block though.
