Master Air Suspension Compressor Failure

My 2020 Renault Master diesel van's air suspension compressor seems dead. It's listing dramatically, the dashboard is lit up with errors, and the computer is throwing codes. I've checked the fuses, but could this be a defective cable or plug connection?

Sounds rough. I had a similar ordeal with my old Volvo XC90 – air suspension is a nightmare. Had the same leaning issue and the light show on the dash. Have you checked the relay for the compressor? That was my issue, before it went downhill completely.

Interesting! I hadn't considered the relay. Where is that typically located? And when you say 'downhill completely', what ended up happening?

On the Volvo, it was in the engine bay fuse box, but Renault might have hidden it elsewhere. Check your owner's manual, first. By 'downhill', I mean the compressor completely gave up. It would still be worth checking, but I'd say visit a shop, the error codes point to a bigger problem!

I think I’ll get it to the professionals. They charged me 95€, likely the cable was the issue as I suspected. Thanks!
