Hi my audi A6 has just come up with the servo restricted warning. I contacted my local plymouth audi who quoted 150 GBP just to plug it in. I have got a local garage to look at it. Plugged it in and have found no fault with the brakes, just the pressure sensor. Now I am really worried that I may face a bigger bill. Is the part available to fit by independent garages? Why such a high price for diagnostics when it took minutes? Does anyone know the part number for an A6 oris it thesame as an A4?
Car is 4years old and only done 10,000miles.
