Hey guys, I too am having troubles, i have the 3pin grey connector on my 1999 3200gt, i bought a foxwell NT530 unit and a fiat3pin adapter and just ended up with "no connection" So i think its time for me to get a VAG KKL cable and a laptop with windows no later than XP, and Unidiag. Can i find the Unidiag software online or do i need redsonnylee to pm me as well haha. Ive been getting CEL after driving for a couple mins, goes into limp mode, Also shifting from 3rd down to 2nd or 1st is impossible before the car has warmed up after 5-10mins of driving. Basically, i need to see what the issues are.
