DS4 Air Suspension Failure
Summary of the thread
A 2022 Citroen DS4 diesel experienced a complete air suspension failure, with the vehicle unable to lift and leaning to one side. The issue was accompanied by an error message and a warning light, affecting the low beam alignment. The problem was suspected to be a bad connection, possibly a defective cable or plug on the compressor. After checking for leaks and connections, it was confirmed that a defective cable was the cause, which was resolved at a repair cost of 95€.

Thanks for the tip! I haven't checked for leaks yet, where exactly should I be looking? And which suspension components do you mean?

I mean, around the air struts themselves, and especially where the air lines connect. Also, check the compressor unit itself for any hissing sounds. Honestly, though, after messing with mine for a bit, I just took it to a workshop and they fixed it quickly. Might be worth considering.

Alright, thanks for sharing your experience! I'll take a closer look for leaks and bad connections, but I'll probably end up taking it to the shop. It was indeed a defective cable causing all the trouble – cost me 95€ to fix. Thanks again!

Sounds familiar. I had a similar problem with my old BMW 5 series. All sorts of weirdness with the suspension. Did you check for any obvious air leaks around the suspension components or the compressor itself?
