Hi, I have an 06 Audi A3 Sportback (1.6 petrol).

Last week - 6 days out of warranty - the ESP light came on. It is on permanently.

Frankly I'm a bit worried about this (and how much it will cost) - and have got it booked in for a check next Tuesday.

I've looked at the fuses and two are marked for the ESP, fuse 4 (or it could be fuse 2...) (which is present and ok) and fuse 20. Fuse 20 is missing - is this meant to be the case (can you have ESP without this fuse?), and would it do any harm to fit a fuse in here, if there is not meant to be one?

I had it in for a service, mot and brake fluid change a few weeks ago, but it was fine until four days ago.

Any advice would be appreciated!
