SLC Suspension Failure
Summary of the thread
A 2019 SLC Diesel owner experienced suspension issues, with the vehicle leaning to one side and displaying a 'ride height malfunction' error. The problem was identified as a faulty air suspension bellows valve, which can cause uneven ride height and a bumpy ride. Diagnosis and repair require specialized equipment, and it was recommended to consult a qualified workshop. After replacing the valve, the error was resolved, and the vehicle's ride height and smoothness were restored.

Thanks for the quick reply! Yes, the car is leaning noticeably to one side. The error message says something about 'ride height malfunction.' The ride is incredibly bumpy too. Is the air spring valve difficult to diagnose?

The symptoms you describe align with a potential air suspension bellows valve issue. Diagnosis might require specialized equipment to test the pneumatic suspension system. I recommend consulting a qualified workshop for proper diagnosis and repair.

Took your advice and brought it to a workshop. You were spot on! It was indeed the air suspension bellows valve. Replaced it, and the error is gone, ride height is back to normal, and the ride is smooth again. Total cost was around 590€. Thanks again for your help!

I have a similar SLC. Suspension failures are common. Does the ride height appear uneven? A leaning vehicle can indicate a problem with one of the air springs or its associated valve. A faulty air suspension bellows valve is a possibility. Check for any error messages related to the pneumatic suspension system.
