Peugeot Expert Air Suspension Fault

I had a similar issue with my Expert. Check the wiring and connections to the air suspension compressor first. A bad connection can definitely cause those symptoms. Air leaks can also cause similar problems, so inspect the air struts and lines as well.

Thanks! Where exactly is the compressor located, and are there any specific connectors I should be paying extra attention to? Also, how can I check for air leaks in the struts and lines?

The compressor is usually near the rear axle. Just visually check all connectors for corrosion or damage. As for leaks, listen for hissing sounds around the struts and lines, or spray soapy water on them and look for bubbles.

Thanks a lot! I'll give that a look, but I think I'm going to take it to a workshop, where they quoted me 95€ for fixing the cable or plug connection. Appreciate the assist!
