My independent mobile car mechanic in the UK (one man and a part time
helper) has access to most of the popular cars sold, we use him for the
wife's Ford Galaxy. He told me the diagnostic software is quite expensive
for any car and for the few Jag customers on his books is not worth paying
for, one popular model that I can't remember cost him around $1000. However,
this is for software used in the portable diagnostic test equipment that
gets plugged into the car's electrical system guiding the mechanic through
the test process and finally providing a legible read out of the fault. If
the car's diagnoses duplicates this process then we should assume the
company and other manufacturers with the same system would be looking for a
similar high value payback. Just a thought.
