Peugeot 107 Air Suspension Issue

That sounds frustrating. My old Citroen C4 Picasso had similar symptoms – leaning and error messages. Is it hissing, maybe from an air leak?

Thanks. No obvious hissing. Could be a slow leak. What was the root cause with your C4 Picasso?

It was a faulty valve on the air suspension bellows. The leak started slow, no hissing at first. Eventually, one side was noticeably lower. Get it checked at a workshop. Probably a valve issue. Good luck!

Thanks for the advice. The workshop confirmed a defective suspension air bag valve, like you suspected. Repair cost 590€. Your insights really helped!
