Not sure if this is the right place but here goes..
I have a 1.8 sri mk4 astra on an x reg plate. I've located the diag socket etc and had a look at it, Some things I was wondering are that I went to do a paper clip test and pins 5/6 ? weren't actually there (as in the metal connector sat inside the plastic moulding)
and the next question is what type of cable will I need for getting a reading (using a laptop)? as I have a vagcom cable which I tried but to no avail.
