I have a 2007 Audi A3 1.6 sport and have been experiencing some problems with it. Its still under warranty so going to contact audi to get it in, but just wondered if anyone knows the problem.

Basically, all the electrics keep turning off when you park it up for a while, so when you try to unlock the car nothing happens. I then unlock the car with the key and try to start it and there is just no power at all. After a few mins the power comes back on and you can start the car.

The warning comes on 'esp fault, please see owners manual' and then the car works fine and all lights go off on the dash.

Anyone got any ideas what this is?

P.S anyone selling a nice S3, after one in the next few weeks?
