S6 Air Suspension Failure Causing Uneven Stance

Looking for advice, my S6 is acting up with suspension height issues. Vehicle sits noticeably uneven between front and rear, plus headlights are misaligned. Warning light popped up on the dash and ride quality has gotten really bumpy. Already checked error codes which point to height control problems. Running a 2015 S6 with 175k on the clock. Previous garage visit left me with doubts, so hoping someone here has dealt with similar air suspension issues and can recommend reliable fixes or share their repair experience. Anyone been through this and got it sorted properly?

Summary of the thread

The S6 experienced air suspension issues, resulting in an uneven stance and misaligned headlights, accompanied by a warning light and bumpy ride. Error codes indicated height control problems. A similar case with an SQ7 revealed a faulty control rod connection to the height sensor as the cause, leading to incorrect suspension adjustments. The recommended solution involved replacing the height sensor and control rod assembly, recalibrating the suspension system, and resetting control module parameters. Addressing these issues promptly is crucial to prevent further damage to suspension components and ensure proper vehicle handling.

Dealt with nearly identical symptoms on my 2018 SQ7 last season. The height sensor malfunction created similar handling issues and uneven stance. The root cause was a faulty control rod connection to the height sensor, which prevented the air suspension system from accurately measuring and adjusting ride height. The control module was receiving incorrect signals, causing the system to improperly adjust the suspension. The fix required: Complete diagnostic scan of the air suspension system, Replacement of the height sensor and control rod assembly, Recalibration of the automotive suspension system, Reset of the control module parameters This was a serious repair requiring specialized equipment and expertise. The symptoms you describe, uneven stance, misaligned headlights, and warning lights, match exactly what I experienced. Left unaddressed, it can lead to premature wear of suspension components and tires. The bumpy ride occurs because the height adjustment system cant properly respond to road conditions. Would strongly recommend having it addressed by a shop with air suspension certification, as proper calibration after parts replacement is crucial.

Thanks for sharing your SQ7 experience. My S6 had the exact same symptoms back then, really helps to know the height sensor was the culprit in your case. Just had the load sensor and control module replaced at my end which sorted the ride height issues. Running smooth now with proper suspension response. Just curious, do you remember roughly what the repair cost you? Also, has everything stayed stable since the fix or have you noticed any other suspension quirks?

Had a similar height control restricted warning on my SQ7. The mechanic traced it to a defective control rod on the leveling sensor, which messed with the ride height readings. Got it fixed last month for 110 Euro, pretty reasonable considering the specialized work needed. Everything has been perfect since the repair. The suspension system now maintains proper ride height and the control module gets accurate readings from the load sensor. No more uneven stance or suspension warnings. The handling feels solid again, just like when the car was new. My advice to anyone dealing with height adjustment issues, get it checked right away. These sensors are crucial for proper suspension function and waiting only risks more expensive problems down the line.

Thanks for the input. Finally got my S6 sorted last week. Total bill came to 850 Euro for parts and labor, but worth every cent considering how much better it drives now. Took it to a specialist who actually showed me the worn load sensor and damaged wiring that was causing the leveling system to malfunction. They replaced the entire height adjustment assembly and recalibrated the air suspension. The ride height is perfectly balanced now and those annoying warning lights are gone. Good call on getting it fixed quickly, they mentioned waiting longer could have damaged other suspension components. Been driving it for a week and the ride feels incredibly smooth again. The air suspension responds perfectly to different road conditions and maintains proper height. Huge difference from the bumpy, uneven ride I was dealing with before.
