I recently got a flea bay blue kkl cable I downloaded vcds lite plugged in to my skoda superb and my mates vw sharan connects and works a treat reads codes from a lot of modules. So I connected up to my mk2 vr it won't connect to ecu.i have wired in a 16 pin obd port pin 4 ground. pin16 feed. pin7 data from pin 43 on ecu and never bothered with yellow wire I think L line as I've no abs etc.i connect car up ignition on start vcds and try an engine scan it just doesn't see the ecu. am I doing something wrong? My mk2vr is Obd1 distributor model.cheees
