Hi All does anyone know the protocols a 1996 2.5 diesel rr M51 engine uses for the diagnostics?
will a obd lead connected to a laptop with the right software work
When I had Bimmers I used an OBDII to ADS (the BMW round plug) adaptor and run the INPA diagnostic gear for the Bimmers....I believe there is some BMW software on the web that probably works but the plug is round so you'd have to work out the pins.
most people use Blackbox solutions like the Nanocom or there is Hawkeye and Lynx that read it too. Generally held not to be as good.
The Land Rover International Rescue map shows members with diag who are willing to read stuff for cake or beer tokens.
