Fault finding & diagnostics - 1

We have many years of experience in advanced fault finding and diagnosis, with a wide range of specialist diagnostic equipment at our disposal, for example:

There are two established methods of fault diagnosis used in the automotive industry.

The first is diagnosis by substitution, where an educated guess is made as to the most likely component to be causing the problem, then this component is replaced with a new one. If the problem does not go away then the next most likely component is replaced and so on.
