Xolani 0 Posted April 30, 2020 Report Share Posted April 30, 2020 Why is the 1995 MK3 VR6 so different, it has OBD1 intake & throttle however the rest is OBD2 from ABS to diagnostic plug near the ashtray. Link to post Share on other sites
Philly-R6 28 Posted May 14, 2020 Report Share Posted May 14, 2020 Hi Xolani, On board diagnostics started out being primarily engine emission control. The later version OBD-2 specifies the diagnostic socket (by the ashtray on this model) plus other standard functions. The connector in earlier versions could be anything suitable.
