Over time, Audi air suspension wear out, so it’s crucial not to lose sight of its current state. Repair of air suspension Audi A7 Sportback is required if:

• the rear suspension of the car goes down when the engine stopped;
• vehicle leans on any of the air suspension racks;
• one of the car parts rises when the engine starts up;
• The clearance of the car is unstable.

The most common problem is poor tightness of the Audi A7 Sportback air suspension connections, which causes air leaks. Often there is fail with the air suspension racks: a depressurization may occur, a sleeve may wear out or knock may appear. Our company offers fast, qualified repair of air suspension racks or their full replacement.

Our car service has all the necessary equipment for fast and high-quality repair of air suspension of Audi A7 Sportback. Experienced and qualified specialists will treat the problem with attention and fulfill all your wishes. They will return soft air suspension to your car with a minimal expenses.

Audi A7 Sportback is one of the most attractive and sophisticated cars of this model range of the popular German concern. The owners of such a car, have access to the maximum level of safety and comfort, which, in addition to convenient instruments, has innovative electronics and rich functionality and is equipped with an air suspension. Improved air suspension Audi A7 Sportback is the «face» of the German manufacturer. It is distinguished by reliability, a large margin of safety and smoothness of the car, even on a rough road.

Air suspension rack. Sometimes, it is required to make a complete replacement of the front air suspension (right and left ) for the correct function of the air suspension. In some cases, you can replace some of the components – a protective glass and anther. Our experts will provide you with repair services of the left and right air suspensions of Audi A6 Allroad (4G, C7) and the replacement of their components.

Air suspension baloon. If the repair of air suspension balloons is not possible, the manufacturer recommends to replace all air suspension balloons at once or at least in pairs (right and left).

Air suspension compressor. Most often, there is no need in all-inclusive replacement of this component in the air suspension system. It is enough to replace individual elements: a piston ring, dehydrator unit, relief valve, pipes, cylinder and sealing gaskets. If there’s failure of the electric motor, the air suspension compressor will have to be replaced completely.

According to technological regulations, diagnostics are held in two stages:

• electronical diagnostics using a computer (the sensors and control units are checked at this stage);
• instrumental diagnostics (inspection of all parts and checking them for wearout and possible malfunctions).We recommend you to contact our service center if you found that:
  • when the engine is started, the back or front part of the Audi car starts to fall;
  • The clearance of the car is not constant (it does not behave as usual);
  • tightness is lost on the connecting elements of the air suspension;
  • when the engine is running, the air suspension starts to «lower» (leak the air);
  • there is knock from air suspension.

  It is recommended to hurry up with air suspension diagnostics. It is easier, faster and cheaper to fix the air suspension of Audi A6 Alroad at the stage of its occurrence and detection.

In this case, anything could happen: an electrical wire could rot, any sensor could fail – that mean that any electrical component connected with the air suspension system could cause a switch to emergency mode. For diagnostics, you will need to connect a computer to the control unit. If only one sensor fails, the air suspension system may continue to operate normally, or it may fail at all.

Sometimes program crashes, and the «Air suspension is not programmed» message appears. The system automatically maintains an medium level. To solve the problem, you need to reflash the «brains» of the air suspension.

The ground clearance of the Audi Q7 will depend on the chosen level. The program provides 4 standard height levels, but you can also recalibrate and adjust the vehicle clearance level for each of the air suspension operation modes. The maximum clearance is limited to the air suspension.

The compressor relay is located under the steering wheel. It is necessary to remove the lower protection, under which the relay unit is located. There are several relays, one of which is a compressor relay. There were cases when by mistake they replaced a wrong relay, which led to the failure of the air suspension compressor, as the native relay was jammed, and the compressor worked even with the shut down engine. You need to be very careful when you are replacing the relay.

Right under the passenger seat, below the bottom. The compressor can be removed from the pit. First you need to remove the protection, which goes the entire length of the body and only then remove the compressor itself.

If there is such an option, you need to switch the air suspension in the jack mode. Or get a fuse on the «brains».

The simpliest is to check with a computer using a specific program. You need to enter the command section, find the compressor temperature sensor and check the temperature. If it has stucked when overheated, it will show a constant temperature in excess of 120-130 degrees. That is, it will show a constant high temperature. Because of this, there will be an error and the system will not work.

If you check without a computer, you need to remove the protection, disconnect the connector from the sensor, take a multimeter, set the selector to measure the resistance with a threshold of 20 kOhm and measure the resistance of the temperature sensor. If the sensor is in good condition, the multimeter will show resistance from 14 to 20 kΩ. Sometimes, resistance can go as high as 21-22 kΩ. Everything will depend on the air temperature outside. If the compressor temperature sensor is jammed, the multimeter will show a resistance of about 1000 ohms. If the sensor has stuck on overheating, the multimeter will show a resistance of approximately 300 ohms.
