I have recently tried to use an op-com code reader to get the fault codes from my veccy, but it refuses to communicate with the car.
I have also tried a vauxcheck interface and can't get that to work either.
Does anyone nearby have a code reader they know is working, so I can at least prove that there isn't a problem with the car side of the interface.
I would go to a local garage, but I imagine they would charge me for the pleasure.
