Audi A7 Air Suspension Problems & Quick Fix Guide

The symptoms you describe remind me of the issues I faced with my 2012 Audi A6. Having some experience with air suspension systems, I recognized these classic signs of control module communication problems. In my case, the automotive suspension issues were traced to a faulty control rod on the load sensor. The uneven ride height was causing similar problems with headlight alignment and ride comfort. The warning light appeared because the control module wasnt receiving accurate height readings. The repair involved replacing the defective sensor components, which solved both the suspension leveling and warning light issues. Total cost was 110 Euro for parts and labor at my regular workshop. Before suggesting specific solutions, could you provide: current mileage, any recent suspension work history, whether the height difference varies or remains constant, If the warning light is constant or intermittent, whether you hear any air compressor noise. With these details, I can share more relevant information from my experience with similar air suspension problems. This type of issue shouldnt be ignored as it can lead to increased wear on other suspension components and affect vehicle stability.

Thanks for the feedback. My odometer currently shows 107775 KM and my last service was just 2 months ago where they did a routine oil change and brake inspection. The height difference remains fairly constant and the warning light stays on permanently. I do notice a faint whirring noise from what sounds like the leveling system trying to adjust, especially after the car has been parked overnight. I checked the service records and no previous work has been done on the automotive suspension components. The height adjustment issue started gradually over the past month rather than suddenly. I am planning to have the control module and sensors checked first before replacing any major parts. Does anyone know the typical labor time for diagnosing these suspension issues?

Thanks for providing those additional details. The constant height difference combined with the continuous warning light matches exactly what I experienced with my A6 when the height sensor failed. The faint whirring sound indicates your air suspension compressor is still functioning, trying to compensate for what it thinks is an incorrect ride height. This matches the classic symptoms of a height sensor malfunction in the leveling system. The gradual onset suggests sensor degradation rather than sudden component failure. On my A6, the diagnostic process took about 1 hour of labor time. The workshop needed to: Check all height sensors, Test the air suspension control module, Verify compressor operation, Inspect air lines for leaks Based on your mileage and the fact this developed over time, I would focus on: 1. Height sensor calibration check 2. Load sensor readings 3. Control module communication test The continuous leveling system attempts can also drain the battery if left unchecked. When my sensor was replaced, the entire height adjustment system returned to normal operation within one drive cycle. For diagnostic costs, most shops charge between 80-120 Euro for a full suspension system check. The actual repair costs vary depending on which components need replacement.

Looking forward to taking it to the shop next week. The diagnostics cost seems reasonable and hopefully they can pinpoint whether its the height sensor or load sensor causing the issue. Given the compressor seems to be working based on the sound, I am hopeful this might just require sensor replacement rather than major air suspension repairs. Will check about getting the leveling system components tested first before authorizing more extensive work. Was concerned about the battery drain you mentioned, will try to minimize driving until the appointment since the system keeps trying to adjust. Really appreciate the detailed information about your similar automotive suspension experience. Its helpful to know what specific tests they should run to diagnose the problem properly.
