Mercedes V Klasse Air Suspension Problems

A defective cable or plug connection can certainly cause those symptoms The air suspension system relies on electrical signals to control the compressor and valves A break in the circuit can lead to compressor malfunction, uneven ride height, and error messages Have you inspected the relevant wiring harness and connections for corrosion, damage, or loose pins

I've had a quick look, but I'm no expert I can see some wires and plugs near the compressor, but I wouldn't know what corrosion looks like, nor how to check for a 'loose pin' Is there a simple way to identify a bad connection Like, a specific wire to wiggle, or a plug I could try reseating Or maybe a YouTube video showing the usual suspects

Given your admitted lack of expertise, I strongly advise against attempting any repairs yourself Incorrectly handling suspension components can be dangerous Your symptoms are consistent with a potential electrical fault within the air suspension system While a simple connection issue is possible, a professional diagnosis is warranted to rule out more complex problems Proceed to a qualified workshop for further assessment

Understood, thanks for the advice I took it to a local shop and you were spot on it was a corroded connector on the compressor They cleaned it up, re-seated everything, and cleared the error codes Air suspension is working perfectly again The 95€ estimate was spot on, so I dodged a bullet there Thanks again for the help
