Yep I bought a junked abs unit, pulled the module and had to take it to the dealer to get it synced w/ my car. Never had the blend door issue. Vac lines were never an issue on my 9-5. They (and radiator hoses) all rotted from heat on my 1997 900, though. We finally traded it when my wife needed a van and the trans was starting to slip b/c I'd let too much fluid leak out since the cooler lines came loose. I think it was also about to go through another DI cassette at the time.
Regarding the oil changes in it, after I got most of the sludge out and updated the pcv, I ran really whatever I wanted, supplemented w/ auto-rx for about 5k at a time.
