Where is the air pump relay located in the Audi Q7?
2 Answers
Audi Q7's air pump relay is located in the fuse box in the right front engine compartment. Relay Overview: A relay is an automatic control device where the output undergoes a step change when the input (electrical, magnetic, acoustic, optical, thermal) reaches a certain value. Automotive relays are relays used in vehicles. Relay Characteristics: Automotive relays have high load-switching power and excellent resistance to shock and vibration. The power supply in vehicles is mostly 12V, and the coil voltage is mostly designed for 12V. In the engine compartment, the ambient temperature range is required to be -40°C to 125°C, while in other locations, the ambient temperature range is -40°C to 85°C.
Last time when I was driving my Audi Q7, I encountered an issue with the air pump not working, and the suspension dropped noticeably. It turned out the relay was inside the fuse box in the engine compartment. The location is on the left side of the front of the car, and the cover has labels indicating the positions. After opening it, look for markings like 'Air Suspension Relay' or similar symbols. My car is a 2018 model, and it was in the upper right corner of that black box. You can gently pry open the cover with a small tool to find it. A faulty relay can cause the air pump to stop, affecting driving comfort. If the location is hard to find, I recommend downloading the official Audi app to check the manual diagrams, which provide detailed annotations of all components. When replacing it yourself, bring a multimeter to test the current and avoid short circuits. In short, don’t rush—take a few more looks at the layout inside the box. Usually, you can fix it without removing other parts.
