As a new member I thought I would share my experience of an ABS pump problem I had. I was quoted £3500 to supply and fit a new one. However after some research and some help from my local Audi specialist, I sent the pump to ECU Testing for a rebuild. The garage removed it and replaced it once it had returned. ECU arranged the courier and the turnaround a couple of days. This was nearly 3 years ago and I've had no problem since and the total cost was less than £300. I understand they may not always be able to rebuild it, depending on the fault, if not you just pay a nominal fee for inspection and send it back. I was very pleased with their service. Also if you haven't found your local Audi specialist (not dealership!) they are definitely worth driving a few extra miles for.

That's good to know Sarah. I knew ECU testing have a good reputation regarding repair of instruments, but was nor aware of their skills with brake servos.
