After replacing the control valve, and finding no leaks, they have contacted me saying they have only one trouble code - and of course the car won;t lift a millimeter.
01575 - Controller Switched off.
But they don't know what to do. The service manager actually offered to pay for transporting it to the Audi dealer
I told him I would check the internet
I'm about to go do some searching, but wanted to post it here first. Has anyone seen this code, fixed it?
thanks!
