Alphard Air Suspension Problem

Thanks for the quick reply! I haven't specifically checked if the compressor is running non-stop, but I'll listen. As for the soapy water test, where exactly should I be spraying? Just around the bellows themselves, or are there other areas? Also, is there any chance it could be something else entirely?

Spray soapy water around the entire airbag – all the seams and where it connects to the suspension. Also check the air lines going to the bag. While it could be something else, the symptoms strongly suggest a faulty air spring valve. Given the error codes you pulled, and the leaning, it's highly probable. With those symptoms, you're probably best off getting it checked by a workshop. Continuing to drive it could damage the compressor.

Thanks so much for your advice. I took it to a local shop, and you were spot on - it was indeed the air suspension bellows valve! The repair cost me 590€. Appreciate the help in narrowing down the issue!

Sounds like you've got a problem with your air suspension bellows valve, which is common enough on older systems. Leaning and inability to lift definitely points towards a leak. Is the compressor running constantly, trying to compensate? Have you checked for any obvious signs of an air leak around the air springs, maybe using soapy water?
