Is this mod only if the car is going into limp mode? Would a CRD benefit from using it?
Looking on the HPD's web site they only have a model for pre Aug 2004 and Aug 2004-2008. This would include early CRD's but not the bulk of them. The site only mentions ZD30DI models, not CRD. My car is a 2007 and I suspect its using the same housing as the DI's but I do not have any limp mode issues.
