Typical symptoms are the car being slow to raise and even not reaching the requested level which puts the error light on, but ignition off and on again and it will try again. If you use diagnostic tool such as VCDS you will have the following codes. 01400 - Suspension Level Control: Control Limit Not Reached. 01772 - Signal from Level Control Pressure Sensor (G291): Implausible Signal.01577 - Turn-Off due to Over-Temp: Upper Limit Exceeded. The above codes all point to a weak compressor which this kit will fix.
If the car is sinking, not sitting level or the suspension error light is constantly on all the time, there is a leak or fault in the system and this will need to be fixed by other means before fitting this repair kit!!
