SQ7 Suspension Failure: Leaning and Lift Issues Exposed

Had similar issues on a 2018 SQ8. The malfunction showed identical symptoms, uneven ride height and multiple electrical warnings. Air suspension problems often cascade into seemingly unrelated error messages. The root cause in my case was a faulty level sensor connector and deteriorated wiring harness. While air leaks were initially suspected, diagnostic testing revealed the electrical connection issues were triggering the suspension system faults. The low beam warning was actually a secondary effect from the suspension control module malfunction. This is typically not a catastrophic failure but requires proper diagnosis. The air struts and compressor tested fine, saving significant repair costs. The main repair involved: Testing suspension components systematically, Replacing corroded wiring connectors, Recalibrating the level sensors, Clearing stored fault codes Given your mileage, getting a full suspension system diagnosis would be advisable. While air leaks are common, electrical issues with the control modules and sensors are equally likely to cause these symptoms. Having this properly diagnosed will prevent replacing expensive components unnecessarily.

Thanks for the detailed input on the suspension issues. My symptoms do sound very similar, especially the uneven ride height and electrical warnings. Really helpful to know it might be sensor-related rather than a full compressor failure. Quick question, do you remember roughly what you paid for the diagnosis and repair? Also, has the load leveling system worked properly since the fix, or have you had any other suspension pump problems come up? This info would really help me budget for the repair and decide whether to look for an independent specialist rather than the dealer.

Just had my car back from the mechanic and can confirm it was a simple fix, not the major air suspension overhaul I initially feared. The malfunction turned out to be a loose cable connection to the compressor causing the system to act up. Total repair cost was 95 Euro to fix the faulty plug connection. The air struts and suspension pump are working flawlessly now. The load leveling system operates perfectly, no more uneven stance or warning lights. After 6 months, I have not experienced any additional suspension issues. The repair shop did a thorough check of the entire air suspension system while they had it in, which gave good peace of mind. This type of electrical issue is quite common and much less expensive than replacing major components. Would definitely suggest getting it properly diagnosed rather than assuming the worst about compressor failure. An independent specialist should be able to quickly identify if you have a similar simple fix.

Finally resolved my suspension headache! Took it to an independent shop that specializes in air suspension systems. The mechanic found it was primarily an electrical issue, corroded wiring to the level sensors was causing the ride height problems. Total bill came to 380 Euro for diagnosis, parts, and labor. The load leveling system is back to working perfectly now. The suspension pump kicks in normally, and the car maintains even ride height. No more warning lights or error messages. They also did a complete check of all air struts and lines while it was in, confirming no actual leaks or mechanical issues. Really glad I asked for advice here first, saved me from unnecessarily replacing expensive components at the dealer. The whole repair took just one day, and three months later, everything is still working great. Definitely recommend getting a proper diagnosis from a suspension specialist before assuming the worst.
