Master air suspension fault
Summary of the thread
The 2010 Renault Master diesel is experiencing issues with its air suspension, causing the vehicle to lean, not lift, and display a speedometer error. The problem is identified as a fault with the air suspension, possibly due to a faulty air suspension bellows valve or air leaks around the suspension air bags. The suggested solution is to check for air leaks and consider professional diagnosis and repair to prevent further damage.

Thanks for the tip. How did you confirm the air suspension bellows valve was the problem? Any specific tests did you run?

Didn't do any specific tests myself. Just noticed the leaning and the hissing sound near the bags. I'd suggest taking it to a workshop for a proper diagnosis. Could save you some time and further damage.

Appreciate the advice. Confirmed: faulty valve. Repair cost 590€. Thanks!

Sounds like a faulty air suspension bellows valve. I had a similar issue with my Master. Check for air leaks around the suspension air bags. Does it also feel like your shock absorbers are gone?
