Not my SW20… my diag. system is not working correctly… And… yes… I know the paperclip (OBD1) and what ports to short out, and the test mode… etc… it does something different… I think part of the problem is that my Circuit Opening relay is bad (COR). At least I think it is after testing it with a multimeter and the fact that it clicks really loud when I try the diagnostic tests… at least it has almost every time.
I have the BGB’s too… and my MK1 is of course OBD1 also… not a huge deal as I can figure this stuff out… but unplugging the light should do the trick if you wanted to pass emissions which I don’t have to worry about either since I don’t plan on driving over 5,000 miles b/c it will sit 8 months out of the year for winter… well… at least it seems like 8 months here.
