the main problem is that if your MAF sensor is blocked, it tells the ECU not enough Air & not enough Fuel.......
you need to keep your MAF sensor as clean as possible
IF I had a CRD, it would have both EGR blocked and a catch can fitted
both do an excellent job of increasing the life of your engine
I have been told previously by a mate (Mechanical Engineer) that they dont work
but
the results speak for themselves
ANY computer controlled Diesel, Di or CRD should have both Catch Can (Provent seems to be the better buying) and EGR blocked
how you deal with the fault codes is neither here nor there
