This morning, I have plugged my new code scanner into the OBD connector and it works...... without a 15 amp fuse in position 130..... so why didn't the £3000.00 one from Snap-On work that the mechanic had ? This really isn't making sense to me at all, I saw for myself, the mechanic plugging it into his van and it was working, but when connected to my e70, no connection could be achieved, or words to that effect.
Anyway, it seems to be working fine, so, as the old saying goes, "If it isn't broke, don't fix it".
