Hey guys and girls I'm new to this forum and I'm looking for some help with my Audi A8 the car was in a little front end accident in the snow and it ripped off the compressor. Fixed the compressor but the compressor isn't getting any power I check the fuses and switched out some relays but nothing! I scanned the car and it's saying the leveling sensors. So my question to all this is does the computer not send power to compressor because the leveling sensors are bad or their is an open? I connected direct power to the compressor and gets air all the way to the air block valve. But it doesn't send air to any other line. What's causing the air block valve not to function?
