Hi mate welcome to S.O.C
Sorry I have to run off now just wanted to let you know it has been seen hopefully someone will be able to help before I get back as there is a lot to read there :)
Tlag, MD two best people I think to ask on here if they come on before me but know both are busy :(
I know with the classic there is a trick you do with the black wires under the steering wheel the classic has a self diagnostic. Will have a look when I get back mate if nobody has been able to help before
:(
