Audi A6 2.5 TDi 2001 - Suspension fault, code 01400 suspension level control limit not reached #Archived Message

Suspension fault light comes on when you try to alter the height. Code 01400 - Suspension Level control limit not reached recorded. Using live data, we have found that the pump opens the rear valve first, then the front. The suspension on the rear does go up very slowly but the pump cuts out after a couple of minutes and logs the above code. Have tested both rear level sensors and they check ok. The suspension maintains its set height, so I assume it doesn't have an air leak, visual inspection doesn't show up any airbag or pipe problems. Has anyone had any problems with the pumps on these?
