RCZ Air Suspension Fault

Sounds frustrating! I had a similar suspension issue with my old Audi A6. The symptoms were almost identical - the leaning, the error message, and the terrible ride quality. In my case, it turned out to be a leaky air strut. Have you checked for any hissing sounds around the suspension when the car tries to adjust its height? Also, does the compressor seem to be running excessively?

Thanks for the quick reply! I haven't noticed any hissing, but the compressor does seem to run quite a bit longer than usual. Was it definitely the air strut on your Audi, or could it have been something else in the system?

Well, initially, I thought it could be just a hose or a sensor, but after a thorough inspection, the workshop confirmed it was the air strut itself that was leaking. Given your symptoms and the compressor running overtime, it's very likely a leak in the air suspension system. I'd recommend getting it checked by a professional as soon as possible before it causes further damage. I ended up paying quite a bit to sort it out, so don't delay!

Okay, I appreciate the advice. I'll get it to a workshop. They've quoted me 590€ for a bellows valve replacement, so hopefully, that fixes it. Thanks again for your help!
