Thanks REDDYZ. It is an automatic. We have run the standard diagnostics and when the warning lights are on the system will not communicate. When they are not lit, no fault is reported. These lights are only on for a few minutes at a time, it is difficult to get the tests done when they are on because they go off by the time we get to the service centre! We have just increased the earthing as suggested for other vague electrical problems, early days yet but no fault, fingers crossed.
