Great video!

I've just fitted a new piston ring and the plug in says it's producing 5.5 bar and the required is over 8 bar. the valve on top of the piston head is raised half a millimeter should that be flat? there's not much gap but could it be enough to lose that extra bit of pressure? many thanks

I removed the Wabco Continental ZSB suspension compressor on my 2005 Audi Allroad. I have a hard and steady 01397 code failure indicating the N111 solenoid was bad. I didn't see any bad wiring anywhere, so I removed the compressor.
How do I bench check this compressor to confirm it's bad? It seemed to be working fine before it failed suddenly as I was driving it. Over a week or so it sunk down evenly to the lowest stops on all fours wheels. When I disconnected the brown airline to it, air was released as of it was being stored well in the system.
The numbers after Wabco are: 001 0424. Does this mean it was made on 2004?
Thanks!

My compressor comes on but wont shut off... I tested the relay and its working fine. Would you have any suggestions on what you think can cause this? Any input would really be appreciated. Thanks & great video! Also wanted to add, have no leaks in my system, as she stays up even when I pull the fuse to disengage the pump.

If there is no leaks the compressor running on is often a symptom of a worn piston seal.

I changed out the Rings and I still and getting the fault. Any suggestions?

[@X8RLtdUK]

+klintous If the compressor was generating good output on bench, it can be a leak within the system.
