V90 Air Suspension Problem

Sounds like a bellows valve issue. Check for air leaks around the suspension airbags. If it's leaking, it's likely the valve is defective. Do you hear the compressor running more often than usual?

Thanks for the quick reply! I haven't specifically listened for the compressor, but I'll check that out. Where exactly should I be looking for the air leak? Any specific points on the airbag I should focus on?

The valve on top of the airbag is a common failure point. Soapy water in a spray bottle will help you find it. But in my experience, if the valve is gone, replacing the entire airbag is the way to go. You'll probably need a workshop to do that.

Thanks a lot for your input! I took it to the workshop, and you were spot on – faulty bellows valve on the air suspension. Repair cost me 590€ Appreciate the help!
