RS7 Air Suspension Failure: Height Drop & Error Messages

Had the same air suspension problems on my 2014 S7. The symptoms matched exactly, uneven ride height, error messages, and that distinctive lean to one side. The air spring system was losing pressure due to a defective valve, causing the shock absorber assembly to behave erratically. The repair required replacing both the valve block and air spring on the affected side. These components work together in the air suspension system, and when one fails, it often compromises the other. The mechanic found microscopic cracks in the air spring that were causing consistent air leaks. This was a serious issue that needed immediate attention. Continuing to drive with failing air suspension can damage other components, including the compressor and adjacent shock absorbers. The entire repair took about two days due to the complexity of the air suspension system. The low mileage on your RS7 suggests this might be covered under warranty, worth checking before proceeding with repairs. These symptoms typically dont resolve themselves and will likely worsen over time. Consider having the entire air suspension system inspected, as problems with ride height control often indicate broader system issues.

Thanks for sharing your experience with the S7 suspension issues. Your description helped confirm my suspicions about the air spring problems. My RS7 is showing identical symptoms and the air leak seems to be getting worse. Quick question, do you recall the repair costs for your air suspension system? Also, have you experienced any related issues since the repair was completed? Just trying to budget accordingly and understand if this tends to be a one-time fix or if I should expect future air spring complications. The ride height drops pretty significantly overnight, which makes me think my air leak might be quite severe. Currently waiting for a quote from a specialist who works specifically with air suspension systems.

Thanks for asking about the follow-up. After seeing the specialist mechanic, my suspension issue was completely resolved. The diagnosis was spot-on, a faulty air suspension bellows valve was causing the air leak and erratic ride height problems. The total repair cost came to 590 Euro, which included replacing the defective valve and a full system inspection. While not cheap, the fix has proven reliable with no recurring suspension problems in the 18 months since the repair. The air suspension system now maintains consistent ride height, even when parked overnight. The specialist confirmed that addressing these air leaks promptly helps prevent additional wear on the suspension system components. They also performed a thorough check of all air lines and connections to ensure there were no other potential failure points. For reference, the repair process took about 6 hours, and the improvement in ride quality was immediately noticeable. The car now sits perfectly level and the error messages have completely disappeared.

Just got back from the specialist mechanic, problem solved and what a relief! The air leak turned out to be exactly what we suspected. Found a highly-rated suspension specialist through an owners forum who really knew their stuff about the air suspension system. The total repair bill came to 780 Euro. They replaced the faulty bellows valve and also discovered minor wear in one air spring that was contributing to the ride height issues. The whole repair took about 8 hours but the results are worth every cent. The suspension now maintains perfect ride height overnight and those annoying dash warnings are gone. The car sits level and handles like new again. Best part is they did a complete system check and confirmed no other components were damaged by the air leak. Ended up costing more than initially expected, but glad I caught it early before it caused problems with the compressor or other suspension parts. The specialist mentioned these issues rarely happen at such low mileage, but when they do, fixing them promptly is crucial. Really appreciate the guidance from everyone here, helped me understand exactly what I was dealing with and get it sorted properly.
