Supra Air Suspension Failure
Summary of the thread
A 2021 Toyota SupraIV with nearly 100,000 kilometers is experiencing air suspension failure, causing the car to lean, not lift, and display error messages, resulting in a bumpy ride. The suspected cause is a leak, potentially from a faulty bellows valve. It is advised to have a professional diagnose the issue, as it involves complex disassembly and error code scanning. The problem was confirmed to be a defective air suspension bellows valve, which was repaired at a cost of 590€.

Where exactly should I be looking for this valve? Is it something I can even check myself without special tools? I'm not super mechanically inclined, but I'm willing to try.

Honestly, on the Supra it's probably best left to a professional. It’s likely the bellows valve, but finding the exact location and confirming requires some disassembly. Could save you money in the long run by not making it worse. Get it scanned and they'll tell you for sure.

Thanks a bunch for the advice! Took it to the workshop, and you were spot on – faulty air suspension bellows valve. Repair cost me 590€, but at least it's fixed now!

Sounds familiar. Had the same issue on my old Audi A6. Check for error codes first. Likely a defective suspension air bag valve causing an air leak.
