Summary of the thread
A 2011 Mercedes GLK with a gasoline engine experienced air suspension issues, including failure to lift, leaning to one side, and dashboard error messages, along with misaligned headlights. Possible causes discussed included a faulty air suspension compressor, air leaks, or a bad connection. The problem was ultimately traced to a loose or defective cable connection to the air suspension compressor, which was resolved by replacing the plug.

I haven't heard any hissing, but I'll listen closer around the air struts. Where are those fuses usually located? If it's not a fuse or an air leak, what else could cause the compressor to fail?

Fuse locations can vary, so check your owner's manual for a diagram. A faulty compressor is a possibility, especially with those symptoms. Sometimes the internal components just fail. Given the error messages, it might be best to get it properly diagnosed at a workshop for an accurate repair estimate.

The shop found a loose/defective cable connection to the air suspension compressor, which was causing the problems. Replacing the plug cost 95€ including labor. Thanks for the advice. I know a bit more about air leaks and the suspension system now.

That sounds like a headache. Air suspension issues can be tricky. Leaning, error messages, and headlight problems all point to a potential issue. Have you checked for any obvious air leaks around the air struts? Sometimes you can hear a hissing sound. Is there a fuse for the air suspension compressor that you could check?
