Peugeot 301 Air Suspension Fault

Sounds familiar. I had something similar happen with my 301. Check the connections to the compressor itself. Could be a loose plug or corroded pins. Also, have you checked the ride height sensors? Sometimes they can cause weird issues if they're not reading correctly.

Thanks! When yours had similar problems, were the symptoms exactly the same? I'm hoping to avoid replacing the whole compressor if it's just a wiring issue. Did you check the sensors or just the compressor?

Yeah, pretty much identical symptoms. Error message, leaning. I fiddled with the connections hoping for a quick fix, but ended up taking it to the shop. Turned out to be a corroded connector like I said. Saved me from buying a new compressor, which would've been way more expensive. I would advise you to do the same.

Great, that's really helpful! I followed your advice and took it to a workshop. They found the defective plug connection just as we suspected. The repair ended up costing me around 95€, so a big win. Appreciate the help!
