I'm clutching at straws really mate.
My mate done his cluster swap with his and he can't get any joy with the lit needles.
What I did was open k commander, click 07 kombi, click on instruments, read eeprom, save two copies to laptop, one labeled modded file-one labeled original file.
Open XVI32 click on file, open the modded file, click on address, click on go to,enter 122 in the box making sure hexdecimal is checked, change F4 to F2 (OR 74 to 72), click file, save as modded file.
Open k commander, click 07 kombi, click instruments, check vehicle model says golf v, read eeprom, click load file (or saved file cannot remember now), click write eeprom, close window, click reset cluster.
I left the car, locked it and left it for a couple of hours as I was told you have to let the cluster fully shut off??
When I went back I had lit needles.
Darren I'v written all this from memory as it's a pain to use k commander on my laptop because of the antivirus, even if I turn it off it causes problems so I have to completely delete it!!
