Jumpy Air Suspension Fault

That sounds like a pain! Something similar happened with my old Vauxhall Astra, although it wasn't air suspension, just regular springs. It was doing the whole leaning thing too, and the lights were messed up. Have you checked all the fuses and relays related to the suspension? That's where I'd start before ripping anything apart.

I did check the fuses – all seem fine, unless I missed one. The relays though, that's a good shout. Whereabouts were yours located on the Astra? And did the error codes you were getting point to anything specific, or just a general suspension fault?

On the Astra, the relays were in the engine bay, in that main fuse box. As for the error codes, it was just a generic suspension fault. Honestly, after messing about with it for ages, I just took it to a garage. Turned out to be a sensor and a dodgy wire. Saved myself a load of hassle in the end. Might be worth getting yours looked at by someone who knows their stuff.

Cheers for the advice. I'll double-check the relays, but you're probably right – time to bite the bullet and get it to a proper mechanic. I did a bit more digging and I think the problem is a defective cable or plug connection. Apparently it's a known issue and the repair will be around 95€ Thanks again for your help!
