If the engine error light comes on am I correct in thinking that the only way of finding out what the error is requires the car to be connected to a diagnostic unit?
I can buy a "CAN BUS OBD 2 OBD2 OBDII USB Diagnostic Interface S2" on ebay that connects to my laptop, is this all I need? If not what do I need?
If that then give me a numeric code, how do I convert that to english. I assume there is a list of codes and descriptions?
