Don't be put off by the negative response to your post.
I suggest you get either the AD200
or the FR704
. The former is a cheaper code reader but should be OK for your car. I have the FR704 and am pretty pleased with it. Agree Clip is too expensive, cheapest I've seen so far is 600 pounds.
I'm not put off by the negative response, I use to own a Vectra, so I'm hands on with cars as having that car gave me nothing but trouble. If I hadn't of repaired it myself I would have thrown hundreds of pounds at it. The paperclip helped me diagnose a few problems too
I would have paid £100+ id it hadn't been for this forum & people power!!
What are the differences between the Clip and FR704? I'm wondering if the FR704 will be able to pinpoint where the fault actually lies
