I have 2010 NPR 200 AMT
Sometimes when idling it sounds like a chuff cutter.
Just had new engine fitted at 150,000 km's under warranty.
Hasn't done 10,000 km's on new engine and makes this chuffing sound.
I thought chuffing might be caused by exhaust brake coming on by itself, as shouldn't be on while idling.
Wonder if this might also cause DPD not do a complete auto burn cycle.
As have issues with this as well.
When new engine installed, they also fitted new DPD filter.
Anyone have any ideas.
