Peugeot 4008 Air Suspension Failure

I'm having trouble with my 2015 Peugeot 4008 gasoline. Mileage is at 73487 km. The air suspension seems to have failed. The vehicle won't lift anymore and is leaning to one side. I'm also getting an error message on the speedometer, and the ride is incredibly bumpy. The error memory points to a faulty bellows valve. Has anyone experienced something similar?

A 2015 Peugeot 4008 with 73,487 km is experiencing air suspension failure, causing the vehicle to lean and produce a bumpy ride. The issue is linked to a faulty bellows valve, as indicated by an error message. Suggestions include checking for air leaks around the bellows, listening for hissing sounds, or using soapy water to detect leaks. Ultimately, professional diagnosis and repair are recommended, which confirmed the defective bellows valve and resolved the issue.

That sounds frustrating! I had a similar issue with my old Audi A6 Allroad. The symptoms were almost identical - the car basically sat on its axles. With those air suspension systems, it's often the air bag valve itself that's the culprit. Think of it like a tire valve that's stuck open; all the air leaks out. Have you checked for any obvious signs of an air leak around the bellows?

Thanks for the insight! No, I haven't specifically checked for air leaks. Where exactly should I be looking around the bellows?

Well, the bellows valve is usually integrated into the air spring itself. You can carefully inspect the area around the air spring – listen for a hissing sound, especially when the car is trying to adjust its ride height. Alternatively, you could spray some soapy water around the connections and look for bubbles. But honestly, considering the error message and the symptoms you're describing, I'd recommend taking it to a workshop with experience in air suspension systems. It's probably best to get a professional diagnosis and replacement.

Appreciate the advice. I took it to the shop, and you were spot on. The bellows valve was indeed defective. Repair cost was 590€. Thanks again!
