Mercedes GLK Height Control Issue
Summary of the thread
A 2012 Mercedes GLK experienced a height control issue, indicated by a warning, low beams off, a low front end, and a bumpy ride. The problem was suspected to be related to a control rod on a height sensor. It was suggested to inspect the wiring and connectors for damage or corrosion, and possibly test the sensors with a multimeter. Ultimately, a defective control rod on a height sensor was identified and replaced, resolving the issue.

Good point about the wiring, I'll check it. Can I test the sensors with a multimeter, or is it more involved? I want to rule out a sensor issue before looking at the control module.

Testing the height sensors with a multimeter is possible, but requires wiring diagrams and understanding the expected resistance or voltage values at different ride heights. Given the potential complexity, I advise consulting a certified Mercedes-Benz technician to properly diagnose the root cause.

Thanks for the advice. The shop found a defective control rod on a height sensor. They replaced it, cleared the code, and now the GLK is riding well again. The cost was 110€.

The symptoms point to an issue within the air suspension system, specifically the ride height control. The uneven height and error code suggest a problem with the height sensors or linkages. Before replacing the control module, inspect the wiring and connectors to the height sensors for corrosion or damage, as a faulty electrical connection can mimic a sensor failure.
