RS6 Air Suspension Failure: Leaky Bellows Alert

Having some experience with Audi suspension systems, I dealt with a very similar air suspension issue on my RS7 (2020 model). The symptoms you describe match exactly what I encountered, uneven ride height and error messages indicating a suspension system fault. The root cause in my case was indeed a defective air spring valve. This created an air leak in the suspension system, preventing proper pressure maintenance and causing the uneven stance. The workshop diagnosed it using their diagnostic system to verify the exact component failure. The repair involved: Complete system diagnosis, Replacing the faulty valve assembly, Recalibrating the entire air suspension system, Testing the ride height adjustment functionality Total cost came to 590 Euro including parts and labor. The repair resolved all issues and the suspension has worked flawlessly since. To provide more specific guidance for your case, could you share: Build year of your RS6, Current mileage, Exact error messages showing on the dash, Whether the suspension issue developed gradually or suddenly, If you notice any changes in the suspension behavior based on temperature or weather This information would help determine if your issue is identical to what I experienced.

Just had my 190000km service done last month, so I can confirm the issue started right after that. The error messages are identical to what you described, and the leaning gets worse by the day. Good to know about the air spring valve being the culprit, I noticed some hissing sounds which probably indicates an air leak in that area. Thanks for the detailed breakdown of the repair process and costs. Sounds like my suspicions about the bellows valve were on point. Will schedule a diagnostic check to confirm before proceeding with the full repair. The timing is frustrating since the ride height was perfect before the service. Did your warranty cover any of the repair costs? Mine just expired.

Thanks for the update on your RS6 situation. After the full repair of my air spring valve, I actually discovered something worth mentioning, make sure they check the entire pneumatic suspension circuit, not just the valve. In my case, while the valve was the primary issue, the service had actually disturbed some connection points in the suspension system. When they did my repair, they found tiny debris in the airlines that got dislodged during the service, contributing to the valve failure. The suspension issue might have started post-service because of similar contamination. The cost breakdown from my repair ended up being higher than initially quoted, about 890 Euro total, because they needed to clean the entire system to prevent future problems. Unfortunately, warranty didnt cover it since it was considered wear and tear. Since your mileage is higher than mine was, you might want to consider having them inspect the air suspension bellows on all corners while theyre at it. Might save you from another suspension failure down the line. Would definitely push for a thorough diagnostic before they start replacing parts. My ride height issues turned out to be more complex than initially thought, even though the symptoms were similar to a simple valve failure.

Thanks for confirming about those error messages, it definitely points to a similar air suspension failure like yours. The hissing noise near the bellows valve area is a telltale sign of an air leak in the system. Frustrating timing with this happening right after service, makes me wonder if something got disturbed during the maintenance work. The ride height issues and uneven stance are getting worse each day, so I better not delay the repair. Since my warranty just expired, looks like I will need to budget around 900 Euro for the full fix, based on your experience. Will schedule that diagnostic check next week to verify the exact suspension issue before authorizing any repairs. Better to catch any additional problems early while they have it up on the lift. Really helpful to know about checking the entire air suspension system, not just replacing the valve. Will make sure to request a thorough inspection of all components when I take it in.
