Audi S6 Suspension Leveling Failure Causing Uneven Ride

The symptoms you describe match what I experienced with my 2018 Audi S7. The leveling system malfunction turned out to be a failed load sensor and damaged control rod on the rear suspension. Key indicators that confirmed the issue: Uneven ride height between front and rear, Active warning lights on dash, Misaligned headlights, Error codes related to the automotive suspension The root cause was a faulty ride height sensor that stopped communicating properly with the leveling system. This created incorrect readings, causing the system to adjust incorrectly. The control rod connected to the sensor was also damaged from constant improper adjustments. The repair required: Complete diagnostic of the leveling sensor system, Replacement of rear load sensor unit, New control rod installation, Full calibration of suspension components, Reset of the leveling system This was a significant repair that required specialized knowledge of Audi suspension systems. Attempting temporary fixes typically leads to additional damage. A certified technician with experience in adaptive suspension systems should handle this type of repair. The issue will likely worsen if left unaddressed, potentially causing damage to other suspension components.

Had similar symptoms with my S6 last year. The height sensor was completely shot and the control module needed recalibration. After replacing both parts, the air suspension started working perfectly again, car sits level and the warning lights are gone. Did you end up getting it fixed? Curious about the repair cost in your case and if any other issues popped up afterward. The load sensor replacement can sometimes reveal additional wear in the system.

Happy to report back on the repair outcome. The Height control restricted warning is now completely resolved after visiting the mechanic. The issue was indeed a defective control rod on the height sensor, which was causing inaccurate readings to the leveling system. The repair bill came to 110 Euro for replacing the control rod and recalibrating the air suspension system. Since the fix, the car sits perfectly level and all warning lights have cleared. The ride height sensors are now communicating correctly with the leveling system. No additional issues have surfaced in the weeks following the repair. The car maintains consistent ride height regardless of load, and the suspension feels much smoother overall. The headlight alignment has also returned to normal since the leveling system is functioning properly again. Definitely worth addressing these suspension problems promptly, waiting too long can lead to excessive wear on other components of the air suspension system.

I took my S6 to a new certified mechanic last week after reading these responses. They diagnosed exactly what others mentioned, a faulty load sensor causing the height adjustment system to malfunction. The repair took about 4 hours and cost 780 Euro total, including parts and labor. The leveling system now works perfectly. The ride height is even, warning lights are off, and headlights are properly aligned. The bumpy ride has completely disappeared. Definitely worth getting a second opinion and finding a mechanic who specializes in air suspension systems. Much happier with this new shop, they showed me the worn parts and explained exactly how the height sensors interact with the suspension control module. No more uneven stance or error codes since the repair.
