Thanks for the insight! No, I haven't specifically checked for air leaks. Where exactly should I be looking around the bellows?

Well, the bellows valve is usually integrated into the air spring itself. You can carefully inspect the area around the air spring – listen for a hissing sound, especially when the car is trying to adjust its ride height. Alternatively, you could spray some soapy water around the connections and look for bubbles. But honestly, considering the error message and the symptoms you're describing, I'd recommend taking it to a workshop with experience in air suspension systems. It's probably best to get a professional diagnosis and replacement.

Appreciate the advice. I took it to the shop, and you were spot on. The bellows valve was indeed defective. Repair cost was 590€. Thanks again!

That sounds frustrating! I had a similar issue with my old Audi A6 Allroad. The symptoms were almost identical - the car basically sat on its axles. With those air suspension systems, it's often the air bag valve itself that's the culprit. Think of it like a tire valve that's stuck open; all the air leaks out. Have you checked for any obvious signs of an air leak around the bellows?
