C4 Electric Air Suspension Failure
Summary of the thread
A 2023 Citroen C4 electric experienced air suspension failure after 92,737 km, with symptoms including the car not lifting, leaning, and suspension error messages. The issue was traced to a fault related to the compressor. After a visual inspection for leaks showed nothing obvious, it was suggested that the problem might be a cable or plug connection issue. The problem was resolved by fixing a loose connector, allowing the car to function properly again.

Thanks for the reply! I did a quick visual inspection for leaks, but didn't see anything obvious. Do you know if there are any specific points where leaks are common, or if there is a way I can test the system without specialized tools?

No problem, happy to help! Honestly, without proper tools, it's tough to pinpoint air leaks. It DOES sound like a potential cable or plug connection issue (that was the error I had!). If it’s not obviously leaking air, and considering the electrical error code, it might be time to get a professional to take a look. It's frustrating, I know, but electrical gremlins can be a nightmare. At least you've had a look yourself, so you are a bit ahead of the game!

Appreciate the help! I took it to a local shop, and you were spot on: a loose connector was the culprit. Repair cost 95€. I am back on the road!

Oh, that sounds rough! Citroen C4s are usually pretty reliable. Air suspension issues can be a real pain. Have you checked for any obvious air leaks around the suspension struts or the compressor itself? I mean, you already checked the error memory which sounds pretty pro, but maybe something simple got missed?
