Audi S6 Air Suspension Failure: Dropping Ride Height

My S6 has developed serious suspension issues lately, the ride height keeps dropping and the car leans noticeably to one side. Getting error messages on the dash and the ride is really rough. Pretty sure it's the air spring or bellows valve acting up. The suspension issue started suddenly and gets worse by the day. Has anyone dealt with similar symptoms on their Audi? Looking for advice before heading back to a shop since my last mechanic experience wasn't great. Car details: 2004 S6, 175000km, 4.2L gas engine.

Experienced similar symptoms on my 2007 Audi A6 4.2 FSI. The pneumatic suspension failure started exactly the same way, uneven ride height and rough driving dynamics. Initial diagnosis revealed multiple air leaks in the system. The bellows valve had deteriorated, causing the suspension to lose pressure constantly. The main issue was not just the faulty valve, the entire air spring assembly needed replacement due to internal corrosion. A complete system diagnostic showed the compressor was overworking trying to maintain pressure, which could have led to total suspension failure if left unrepaired. This is definitely a serious issue requiring immediate attention. The repair involved replacing both front air springs, bellows valves, and checking all air lines for potential leaks. The suspension control module also needed recalibration after parts replacement. When dealing with air suspension issues, partial fixes often lead to recurring problems. The interconnected nature of these systems means one failing component can accelerate wear on others. Getting a complete diagnosis and proper repair is crucial for long-term reliability.

Thanks for sharing your experience. Your suspension issue sounds identical to what I dealt with on my S6. The air leaks completely messed up the ride height and stability. Been about 8 months since I got it fixed, running smoothly now with no shock absorber issues. Just curious, what did the full repair end up costing you? My pneumatic suspension overhaul was pretty expensive, but at least the fix seems to be holding up well. Did you notice any other problems pop up with the suspension system after the main repair?

The total repair bill came to 590 Euro for fixing the faulty air suspension bellows valve, which was definitely worth every cent. Since seeing the mechanic and getting the proper fix, the pneumatic suspension has been working flawlessly. No more uneven ride height or stability issues with the suspension system. The shock absorber components were also thoroughly inspected during the repair, and everything checked out fine. The mechanic confirmed that catching the bellows valve issue early prevented additional wear on other suspension parts, which could have led to much costlier repairs. Eight months of trouble-free operation matches my experience, once properly diagnosed and fixed, these suspension systems are quite reliable. No secondary issues have emerged since the repair. The car maintains perfect ride height and the suspension works exactly as designed. The key was getting a complete system diagnosis rather than just treating individual symptoms. When the entire suspension system is properly maintained, these cars provide an exceptional ride quality.

I finally got my S6 fixed last week after dealing with those suspension problems. Found a good independent shop that really knew their stuff about pneumatic suspension systems. They spotted multiple air leaks right away and showed me how the bellows valve had completely failed. The repair ended up being more extensive than expected. Beyond just the valve, they had to replace both front air springs and flush the entire system. The ride height is perfect now, no more leaning or sagging. Total cost was 2100 Euro, which hurt the wallet but beats having to replace the whole suspension later. The technician explained everything clearly and even showed me the worn parts. Much better experience than my previous mechanic who just wanted to throw parts at the problem. After a week of driving, the car feels like new again. No more error messages and the ride is properly smooth like it should be.
