Mercedes C Klasse Air Suspension Problem Solved

My 2002 Mercedes C Klasse diesel with 189286 km on the clock won't raise itself and is leaning. There's an error in the memory and a message on the speedometer. The low beams are also misaligned. Could a defective cable or plug be the problem, or should I look at other suspension parts? The repair estimate is 95€.

Sounds familiar. I had a similar issue on my C Klasse but didn't check the error codes. Is the compressor running constantly? Could be a bad relay, or worse, the compressor itself. Check the air struts too, any hissing?

The compressor does seem to be running more than usual. How can I tell if the struts or the compressor are the problem?

If the compressor is running overtime, it's likely struggling to compensate for an air leak. The struts are a common culprit, but honestly, without proper testing gear, it's tough to pinpoint. I'd suggest a workshop visit. They can pressure test the system.

I followed your advice and visited a workshop for a pressure test. A defective cable was located and replaced, as suspected. The system is now working.
