Working with a 2007 Bentley Continental GT car has been sitting for a while. Put two brand new batteries got it started, and now running into an issue with the air ride system. The air compressor is not powering on and I’m getting a gear fault code on the dash I’ve checked the relays and fuses, and also checked to make sure that the body control module was plugged in. When I manually jumped the compressor wire underneath the car it turns on and runs. Not sure what to check next. Any help would be much appreciated.
