can some one please explain the difference between the general OBD cable used for diagnostic and vgacom (or BMW special cable) ?
here is summery of my problem and why i am asking this question,
I have a genden ELM (genden.co.uk
) and one of the e36 20 to 16 pin convertor but i can not connect to the ecu after trying numourous setting changes and ...
Basically my interface recognised the battery voltage and that is it.
However the same tool without the 20 pin convertor works on e46 without a problem which has the new 16 pin
any ideas as to why?
