SQ8 Air Suspension Height Failure Needs Expert Fix

Had a similar issue with my 2018 RS6 Avant. The height sensor malfunction started gradually, first with uneven ride height and misaligned headlights. The control module was receiving incorrect signals from a faulty height sensor, causing the air suspension to behave erratically. The root cause was a damaged control rod connected to the height sensor. Moisture had corroded the connection points, leading to inaccurate readings. The load sensor was also affected, causing the system to misinterpret vehicle weight distribution. This is a serious suspension issue that requires proper diagnosis and repair. The height adjustment system needs specialized equipment to properly calibrate after parts replacement. In my case, they replaced the height sensor assembly, control rod, and recalibrated the entire system. These symptoms typically indicate either a failed height sensor, damaged control rod, or compromised wiring. Given the mileage on your SQ8, its likely time for a thorough suspension system inspection. The repair requires specific diagnostic tools to properly reset the control module and height adjustment parameters. Continuing to drive with this issue risks further damage to the air suspension components.

Thanks for sharing your experience with the RS6. This actually mirrors what happened with my SQ8 last year. The leveling sensor started acting up which threw the whole air suspension system out of whack. After getting it sorted, the ride quality went back to normal and those annoying warning lights finally disappeared. Could you remember roughly what you paid for the repair? Also curious if youve had any other suspension issues pop up since getting it fixed? My air suspension has been solid after the repair but always good to know what to watch out for.

Really glad I could help! Since getting the height control restricted warning fixed on my RS6, everything has been running perfectly smooth. The automotive suspension repair cost me 110 Euro to replace the control rod on the defective sensor, which was causing all those leveling system issues. The repair shop found moisture damage on the load sensor connection, similar to what youre describing with your SQ8. After they sorted the control module calibration, I havent experienced any more problems with the height adjustment system. Its been about 18 months now, and the suspension is still working exactly as it should. Just keep an eye on any unusual noises or uneven ride height, these are usually the first signs if the leveling system starts acting up again. But with proper maintenance of the control module and sensors, these systems are generally quite reliable.

I finally got my SQ8 fixed and wanted to share how it went. Took it to a certified shop that specializes in air suspension systems. The mechanic immediately identified issues with multiple leveling sensors and a failing control module. The system was retaining moisture, which had corroded several connection points. Total repair came to 2800 Euro, which included replacing both front height sensors, one load sensor, and recalibrating the control module. They also cleaned and sealed all the connection points to prevent future moisture damage. The suspension issue was worse than initially thought, but the thorough fix was worth it. The car now sits perfectly level, rides smooth, and all warning lights are gone. Headlights are properly aligned again. Going to a specialized shop made a huge difference, they knew exactly what to look for and had all the right diagnostic equipment for the height adjustment system. Thanks again for the guidance. Really helped me understand what I was dealing with before heading to the shop.
