Hi Mark,how did you get on buddy?
Removal of the BeCM showed that it had enjoyed a cafe-latte or other such beverage at some point in the past(not me Guv'nor), and so it has been sent off for testing and repair/replacement.
I won't know more till next week now. It's a shame to have to spend c.4-500 quid on a vehicle worth about £1,000 to £1,200. But it is cheaper than buying a new and unknown car I suppose.
As soon as I get a result, I will update the thread. Thanks for asking and for all the support. It is much appreciated.
Dan.
