The EHM does not throw a CEL... It does have the tendency to smell, smoke, and leak oil on your driveway, though. IMHO, it's an unnecessary mod.
X2 and oil that goes through the CA system will be burnt, just like the fuel, and it requires zero maintenance, GDE pulled a CAC and ony got like a spoon of oil out of it. With 20PSI+ of charge air, the oil will not build up in the CAC. It is really just a matter of how much time you want to be under the hood tinkering. No one has ever had a CRD blow up because it did not have and EHM or a Provent.

If the EHM or provent should freeze shut in the winter, from the condensation it emits, you can count on your engine seals being blown. You have a choice get rid of the EGR fumes (GDE or ORM), or get rid of the CCV oil (EHM or Provent with freeze risk), one by itself is no harm.
