Might I add a BIG SHOUT out to njw1967, who is basically my brother from another mother :-)
He got me over the final hurdle of my ineptitude and managed to talk me through to getting that bloody 30kOhm box out to check. Ordered the one above now patiently await some kicking action :->
Oh, of course thank again to njw1967 for the advise on the bimmercode setup I have to buy to code it
Not forgetting all the other folk who weighed in of course - will keep you all posted on the outcome.
BE BRAVE.
