VW Sharan Air Suspension Failure Causing Uneven Ride

Had the same suspension failure warning on my VW Touareg 2017 TDI. The symptoms matched exactly, uneven ride height and the car leaning toward the passenger side. The bellows valve was leaking, causing the air suspension system to malfunction. The repair involved replacing both the valve unit and associated air lines. The suspension system requires proper diagnostic equipment to identify the exact location of air leaks. In my case, the technician found the bellows valve had deteriorated, allowing air to escape and preventing proper pressure regulation. This is a serious issue that needs immediate attention, as continued driving can damage other suspension components. When the shock absorber cannot maintain proper ride height, it puts extra stress on surrounding parts. The complete repair restored normal suspension function and eliminated the warning lights. Worth noting that the air suspension uses multiple pressure sensors and valves working together. Once one component fails, the entire system becomes compromised. Regular inspection of the air lines and bellows can help catch these issues before complete suspension failure occurs.

Thanks for sharing your experience with the Touareg suspension issue. I recently faced similar problems with my Sharan, and your description helped me identify what was wrong. Quick question: do you recall the total repair cost for the air spring system fix? Also, has everything been working properly since the repair, or have you noticed any other suspension-related problems? The ride height issue can be quite concerning, so it would be helpful to know if the fix was a permanent solution or if I should expect other components to need attention soon.

Just wanted to update, since getting my Touareg repaired, the air suspension has been working flawlessly. The total cost was 590€ for replacing the faulty air suspension bellows valve and associated components. The mechanic confirmed the diagnosis matched your symptoms exactly. The suspension system has maintained perfect ride height since the fix, with no error codes or warning lights appearing. The shock absorber and air spring components are all functioning as intended. Its been 18 months now without any issues, suggesting this was indeed the root cause rather than a temporary solution. Regular maintenance checks show the air suspension is holding pressure correctly, and the bellows valve replacement seems to have fully resolved the problem. While these systems can be complex, once properly repaired they tend to be quite reliable. The repair cost was worth it to restore proper function and prevent damage to other suspension components. Based on my experience, addressing the valve issue promptly helps avoid more extensive suspension repairs down the line.

Thanks everyone for the helpful replies. After taking my Sharan to the repair shop, they diagnosed a faulty bellows valve in the suspension system, just as suggested. The total repair came to 650€, which included replacing the valve and checking the entire pneumatic suspension setup. Getting it fixed was definitely the right call. The ride height is now perfectly balanced, and those annoying warning lights are gone. The mechanic showed me the old valve which had significant wear causing air leaks in the suspension system. The repair took about 4 hours total. They did a full system pressure test afterward to ensure everything was sealed properly. Been driving for a week now and the suspension is working great, no more leaning or bumpy rides. For anyone facing similar issues, addressing suspension problems early really helps prevent bigger headaches later. The repair cost was reasonable considering the complexity of air suspension systems.
