Looking at buying an OBD II usb cable and software to read codes and look at basic info such as engine speeds, air intake e.t.c. Airbag light has come on a few times so would like to see what that is.
Also dads jag has thrown up an engine managment light and so would ideally like to read that. Question is which should i buy. Seen a few on ebay as below, but does anyone have one to reccomend or know which one is the best?
Thanks in advance,
