What are the common faults of Audi air suspension?
3 Answers
Audi air suspension faults include air leakage and failure to adjust height. The following are detailed explanations about Audi: 1. Background: Audi is an international high-quality automobile developer and manufacturer. Currently a subsidiary of Volkswagen Group, headquartered in Ingolstadt, Germany. 2. Model Series: Audi's main production series include A series (covering AO, A, B, C, D class models), Q series, R series, TT series, S series, RS series, and the Allroad series derived from A series.
I've been driving an Audi for many years, and the air suspension has failed quite a few times. The most common issue is airbag leaks, where the rubber airbags age or develop cracks, causing the car body to suddenly sink or tilt while driving, especially noticeable on bumpy roads. Compressor failures are also very annoying—once the motor burns out, the system can't pump air, resulting in abnormal noises or complete failure upon startup. Sensor problems frequently occur in Audis; dirt or water ingress can trigger false height errors, causing the suspension to adjust erratically. The control module sometimes fails and requires reprogramming or reinstallation at a professional shop. During diagnosis, it's important to check the vehicle height and compressor sounds. Repair costs are high, starting at several thousand yuan, but regular maintenance like cleaning the lower components can extend its lifespan. A faulty air suspension affects both comfort and handling, making long-distance driving exhausting, so it's best to address issues early to avoid bigger problems.
I experienced an air suspension failure while driving my Audi A6. The car body suddenly tilted to one side as if it had collapsed. After inspection, it was found that the airbag had a puncture and was leaking. The compressor also had issues—it made a buzzing noise upon startup but couldn't build enough pressure. Audi's electronic components often malfunction; for example, sensors misjudged the height after getting clogged with dust. Repairing the air leak required replacing the entire airbag kit, which cost several thousand. If the car feels unstable during daily driving, it's a warning sign of suspension problems. To prevent issues, avoid driving too much on rough roads and clean the dust regularly to minimize trouble. Although the cost is high, safety comes first. It's recommended to visit an authorized 4S shop immediately if any abnormalities are detected.
