Audi Q8 Air Suspension Failure Causes Vehicle Lean

Having dealt with air suspension issues on my 2020 Audi Q7, I can share some relevant experience. While I consider myself to have moderate expertise with suspension systems, this particular issue required professional intervention. My car showed similar symptoms, uneven ride height and warning lights indicating air suspension malfunction. After taking it to a workshop, they discovered the root cause was actually a damaged cable connection to the compressor, rather than complete compressor failure. The fix was relatively straightforward and cost 95 Euro for the repair of the wiring connection. The entire diagnostic and repair process took about 2 hours. This was much better than replacing the entire air suspension components, which would have been significantly more expensive. However, to provide more specific guidance for your Q8, could you share: What specific error codes are stored? Is the suspension dropping immediately or gradually? Does the compressor make any noise when trying to adjust height? Have you noticed any moisture or rust around the air struts? These details would help determine if your issue is similar to what I experienced or if you might be dealing with more extensive air suspension system damage.

Thank you for sharing your experience. After having my Q8 inspected at the last service at 129146 KM, the technician identified that the load leveling system issue was caused by a faulty air compressor relay. Unlike a complete suspension system failure, this explains why the ride height would sometimes adjust correctly before failing completely. The warning lights have been consistent, and the air struts appear intact with no visible damage. The suspension components were thoroughly checked, and no leaks were detected. This points to an electrical rather than mechanical issue, which is somewhat reassuring for the repair costs. Could you share whether your repair also involved any relay replacements? The quote I received seems higher than your repair cost.

Thanks for the follow-up about your Q8. My experience with the Q7 actually evolved beyond the initial cable repair I mentioned. After about 2 months, I did end up needing a relay replacement as the electrical issues persisted. The relay replacement cost was around 280 Euro including labor, which sounds more in line with your quote. The suspension pump started working reliably after this fix, and the ride height control returned to normal function. The repair took about 3 hours, mainly due to the location of the relay requiring removal of several components for access. A few key points from my experience: The air struts and other suspension components remained in good condition, No air leaks were detected in the system, The electrical fix resolved all warning lights and height control issues If your mileage is similar to mine (I was at 125000 KM), this type of electrical issue is not uncommon. The relay replacement proved to be a complete solution, and I have not experienced any suspension system problems in the 50000 KM since the repair.

I appreciate the detailed information about the relay replacement. The cost figures actually align well with the 295 Euro quote I received. My situation does sound nearly identical to yours, especially the part about intermittent height adjustment before complete failure. The inspection revealed no air leaks or damage to the air struts, which matches your experience. The compressor itself is actually responsive but inconsistent, suggesting the relay is indeed the culprit. I have scheduled the repair for next week. One concern remains about the electrical system. The technician mentioned checking the entire wiring harness while they have access during the relay replacement to prevent future issues with the air suspension components. This would add about 150 Euro to the total cost. Based on your long-term success after the repair, would you say this additional inspection is worth considering?
