Sorry for the slow reply - I have two D2's now, and I want to be able to maintain both of them (until I sell one of them) - my most pressing need is to eliminate the immobilizer on my 2004 since it is popping a p1668 code. The 2004 is an 'S' with no sunroofs and basically very few options at all, and is going to be the one I keep, so I want to simplify everything possible.
