Mercedes X Klasse air suspension failure

Your predicament resonates with my own experiences concerning the air suspension system in the X Klasse. The leaning, error messages, and compromised ride quality, points towards a potential air leak within the air spring assembly. Have you inspected the air lines and fittings for any signs of degradation or leakage?

I haven't personally checked the air lines myself, but the mechanic mentioned something about an air leak. Is the bellows valve a common point of failure? And is there any way to confirm it's definitely the valve before I pay for a replacement?

Confirmation of the precise component failure without diagnostic equipment is challenging. However, given the symptoms, a defective bellows valve is a plausible cause. These valves, responsible for maintaining appropriate air pressure within the air spring, are susceptible to wear and tear. Visual inspection may reveal obvious damage, but a pressure test is often necessary for definitive diagnosis. I would recommend consulting with a qualified technician for a comprehensive evaluation.

Appreciate the advice The bellows valve in the air spring was the culprit. Cost me 590€ to get it sorted, but at least the X Klasse is riding smooth again Thanks for confirming my suspicions
