Default Re: Rear air problem

If you still have the original single stage compressor that the 03's came with I believe there is A calibration update for excessive cycling which will cycle on the exhaust valve and over time deflate the bags even with the key off. If you have the dual stage compressor they are not programmable and you have to have it diagnosed, likley the assembly would need to be swapped out as parts are not available
