I have been a subscriber since these bulletins were started by Peter Coombes circa 1990

Lately they have gone away from being informative articles on a particular vehicle system, ie: Bosch Motronic,how it works,how to check it,what values to expect,how to repair it.

Still useful information though but vehicle specific, I have made an Excel workbook on pc and enter each topic as it arrives then its easy to locate under manufactures headings.
