Peugeot 508 Air Suspension Problem

My 2021 Peugeot 508 with a gasoline engine has an issue. At 150062 km, the air suspension isn't adjusting height and leans noticeably. The ECU has an error, the dash shows a warning, and the ride is very bouncy. I think it's a bad valve in the air suspension bellows. Anyone seen this?

I also own a 508 with air suspension and I know this problem. Is the error message persistent? Does the compressor still run when you start the engine?

The error is persistent, and the compressor tries to start but seems weak. What was your experience with similar symptoms?

Yes, exactly the same symptoms. The defective valve caused the air leak. You should go to a workshop and let them replace the air suspension bellows valve. Cost me around 600€.

Sounds like my diagnosis is right, and replacing the air suspension bellows valve is the way to go. The estimated cost of 590€ matches your experience. Thanks!
