[iananthony15]

Hi I have vauxhallcalibra with an engine warning light on and what I'm after is a diagnostic tester can anyone help on where I can get one from

[Topbuzz]

see my website to read engine trouble codes, just short pins A and B out with a paperclip

Otherwise for any more advance readings I have only found opel-scannerCAN to work
