Hi there. I'm looking for a bit of help with a GT1 I just bought.

Here's the deal:

IBM T30 Laptop boots and loads DIS, GT1 head powers up and shows up connected in DIS screen.

When I try and read a car, it fails every time. I've tried with a 2002 735i and 2000 318i but neither will read.

The green and amber led on the GT1 are both on when I run the diagnostic. No red temperature led.

Anyone any suggestions?
