What makes a vehicle OBDI or OBDII is a year thing, not a model thing. All '97 and up vehicles are OBDII which the D1 falls into until '98. From '99 - '04 it is a D2. My old '95 DI and my friend's '96 DI are OBDI with a dizzy and my '97 is OBDII with coil packs. My '95 Golf and M3 were OBDI compared to my (then) roommate's '97 Jetta and my Dad's '97 M3 which were OBDII.
