Mercedes ML hybrid suspension issue

Sounds like a nightmare. I had a similar ride height problem with my old Audi A6. Is it throwing any specific error codes related to the air suspension system? It could be a leak or the compressor itself struggling to maintain pressure. I would check the basics first, have you inspected the air lines for damage?

Thank you for your response. I did not observe any compromised air lines upon my initial inspection. Could you please clarify the error codes you encountered with your Audi? Specifically, were they indicative of a bellows valve malfunction?

The Audi was throwing codes related to the ride height sensor and pressure regulation, it wasn't exactly the bellows valve itself. My experience suggests that you should get it scanned with a proper diagnostic tool. Sounds like you are describing a complex issue. A workshop might be more helpful.

Understood. Thank you for the clarification and advice. I have scheduled an appointment for a diagnostic assessment. The estimated repair cost for replacing the defective air suspension bellows valve is 590€.
