I am about to book in my S3 to get the Haldex checked out, I thought it was my new tyres but I believe there are known issues with pump failure where the car returns to 2WD. I am losing traction quite a bit and seeing the ESP light flash up.
If you have a failure of this nature and it goes in to 2WD mode do any dash lights come up ?
