Peugeot 307 Air Suspension Problems

I had a comparable situation with my Peugeot 307. From your description, it sounds like a potential air leak in the system. Have you inspected the air spring itself for any visible damage or wear? A faulty valve block could also be the culprit, preventing proper inflation and causing the leaning.

Thank you for the insight. I have not yet conducted a thorough inspection of the air spring itself. Considering the error codes point towards the valve, is it plausible that the air spring remains intact, with the valve being the sole source of the malfunction?

While it's possible the air spring is still functional, a defective valve often leads to overworking of the compressor and eventual air spring degradation due to pressure imbalances. Given the symptoms and error codes, a valve replacement is likely necessary. However, I would strongly advise a comprehensive diagnostic check at a reputable workshop to confirm the exact cause before proceeding with any repairs.

I appreciate the advice. Following your suggestion, I had the vehicle inspected at a workshop. The issue was indeed the air suspension bellows valve, as initially suspected. The repair, including parts and labor, amounted to 590€. Thank you again for your assistance.
