Peugeot 208 Suspension Fault

Sounds like a ride height issue, which, given the symptoms, could be related to your pneumatic suspension, sometimes called air suspension. Basically, it uses air springs instead of traditional metal ones, with an air pump or compressor to maintain and regulate vehicle height. This setup relies on something called air suspension bellows and a valve to control the air flow. When these valves go bad, the air spring loses pressure. Is it showing a specific code?

No specific code, just a suspension error. So, you think it's the air spring valve?

Yep, given the symptoms, I'm leaning towards a defective suspension air bag valve. That would explain the leaning, the inability to lift, and the bumpy ride because the shock absorber would be essentially non-functional on that side. I'd get it checked at a workshop. The repair will likely cost around 590€.

Thanks. Turns out the suspension air bag valve was indeed defective. Replaced it, and all is well.
