Many thanks to all for your help & sorry I not been back, I have been unwell for a time.
I'm thinking of selling the Rangie now apart from the current issue its all in pretty good order with only 66800 on the clock, anyone interested?
For sale section.
I'd go back to the start of this thread though and check off each suggestion in turn. Might even be worth making a summary of the engine and year and what you tested and what the result was each time.
