Jesus man there is no readout with that?
If 0074 coordinates with my error after my bags were replaced when I read the module with DIS, you do in fact need to do the air compressor repair.
My code was EHC74 accumulator filling requested pressure remains constant. I swapped my compressor out for a new one and have had perfect operation for over a year now.
The rebuild kits were not available readily then, and I found a gently used compressor.
Search eBay for "wabco compressor rebuild kit" and you'll find it for about 50 bucks.
Should fix your issues.
