I was pulling your leg Tolsen.
Cheap scanners can and do invent faults,or at least interpret faults in the wrong way.My father in law bought a cheap scanner from
and it said that I had a traction control fault on my car and that the auto box was faulty.My car is manual and doesn't have traction control.
I am currently testing out a cheap code reader I've purchased,and so far things are going well,although it's nothing compared to the Snap-on unit we have at work.The cheap one being about 1/90th of the price of the Snap-on one may sweeten the deal though.
.Even our one at work is gradually becoming dated though,and at the moment we can't justify the £1000+ to update the software for it,but we do have a very good local chap with a Launch X-431 (which is the dogs do-das) that helps us out if we can't connect to a car.
One thing to keep in mind though is that you can spend millions on scanners,it's the nut using it that can make the difference between a successfull diagnosis and an incorrect one.
