JAGUAR FAULT FINDING SERVICES
With any fault-finding, the first step is to decide where to begin investigations.
Sometimes this is obvious, but on other occasions, a little detective work will be necessary. The owner who makes half a dozen haphazard adjustments or replacements may be successful in curing a fault (or its symptoms), but will be none the wiser if the fault recurs, and ultimately may have spent more time and money than was necessary. A calm and logical approach will be found to be more satisfactory in the long run. Always take into account any warning signs or abnormalities that may have been noticed in the period preceding the fault — power loss, high or low gauge readings, unusual smells, etc — and remember that failure of components such as fuses or spark plugs may only be pointers to some underlying fault.
Modern vehicles rely on computers and computers are needed for fault codes reading; even when the codes are read and a report given there is still a bit of investigation to do. This is most certainly best left to the professionals… those professionals that know Jaguars!
