    Recently I've shutter valve stuck. Truck is building air only in primary tank. Is this problem may be related with my egr resistors bypass.? Anyone help please?

    No air building has nothing to do with egr in engine. I would think check valve on airtank.

    I used to work on Volvos with ISX and some volvos had VGT Actuator air supply connected to secondary tank, so if this actuator is bad - compressor wont building air.

    On other trucks engine air actuators are supplied from acc tankl and if actuator leaks air - no cab suspention )) LOL

    I guess I should have asked what engine he had and if any audible air leaks

    Thanks gear head. I have DDS 60 12,7. Problem is actually in compressor. I need to clean up and hopefully not replace. I don't have any leak.
