Oh well..not the relay. The compressor won't even pump anymore. Now the suspension lights are all lid up and the "Lift" option is greyed out. Going to order a compressor and hopefully that will take care of it.

Could just be that the 30A fuse blew (near the relay) because of the possible bad relay. Or, If the compressor keeps running, it overheats and should shut down. It will eventually reset and if the relay is stuck, the pump will run until it overheats. Rinse, lather and repeat...

Same deal for me on a 07 S8. Compressor runs intermittent. Pull the battery...sometimes a reset happens and compressor stops....but when continues to run pull batt for sure.

Replaced the 373 relay under the dash as noted by others....even bought two....replacing the relay did not stop the compressor....

I hear there might be another relay under the passenger side carpet....yet to conform that. Hope so because replacing the under dash relay did not resolve the issue.

Anybody know about a second relay?

Thanks.
