Hello, I recently had to replace the front air shocks and compressor on my A6. It worked perfect for about 3 weeks than the compressor quit working. I sent it back to Germany and they said there was moisture inside causing it to sort and refused to warranty it. So i said screw you guys and purchased another from a us dealer. After installing it today in still getting the yellow and green light and it's not coming on. Everything is hooked up properly and I replaced the relay....... And ideas?
