Hi, I have an Audi Q7 2007, V8 4.2 Quattro. 5 days back after coming back from a friends house i noticed front of the car was way too lower than the back. Drove it a bit and the car was bouncing like crazy. Took it to the workshop the next day. At first the guy said its the compressor and he will have to change it. As soon as he took the compressor out and checked it he said the compressor is working perfectly fine so its a shock somewhere. So the passenger side shock had to be changed since it was broken and the car was more lower on the passenger side front. They tried to level the car through computer so the back which was higher also went lower almost same to the front. After changing the shock the car was only lifting from front and not from the back then he said the motor needs replacement after motor replacement the car still is not lifting from the back. The front lifts for a few seconds then it goes down as well. Could it be a faulty shock or what please help been 5 days

 

Sounds like leak somewhere in the air suspension. That is the first place i would have started. The shocks / motor are very expensive.
