Corsa Air Suspension Failure

I had a comparable situation with my Corsa. The symptoms you describe are quite familiar. Have you checked for any evident air leaks, especially around the compressor and air struts? Also, were there any unusual noises coming from the compressor before it failed completely?

Regarding the air leaks, I've conducted a visual inspection but haven't detected anything obvious. I'm also using soapy water to look for bubbles, but so far nothing. Concerning unusual noises, there was a distinct humming sound emanating from the compressor area prior to the complete failure. Could you elaborate on how you resolved your similar issue?

In my case, the humming sound also preceded the compressor's demise. Considering your thorough inspection, and given the symptoms, the likelihood points towards a faulty compressor or a connection issue as you initially suspected. I would recommend taking it to a workshop to properly diagnose if you are not able to do it yourself, as these systems require specialized tools.

I took your advice and brought my Corsa to a specialized workshop. As suspected, it was a defective cable to the compressor, causing it to not function correctly. The damaged wire was replaced and cost 95€.
