Cheers Alex, not tried much atm, was waiting on a loom (that hasn't materialised) as the Alternator / Pulley / Battery / Belt are all fairly new.
Haven't got much time atm, is it dangerous to be driving with the G201 problem? I'm not doing mega miles, but still.
Also, by actually getting the G201 error is the system communicating with the part? OR could it be a wiring issue... reason I'm hanging on that, is that it's so conicidental that I didn't even drive the car far after having everything out; round the block and that error showed up... just don't want to chuck hundreds at it, for it to be wiring related.
