I have located a secondhand replacement part 8644347 yellow sticker, but have been told by two seperate sources, that if I try and fit a used ETM to my car a) it won't work and b) it won't accept the software to make it work.
I am confused. Why are there so many used ETM's for sale if they simply will not work on another car?
Is the above true or am I been spun a yarn, by the blood sucking dealers?
Any information,experience or advice will be gratefully received. Kindest regards.
