None of them were fully OBDII compatible. Requirement for OBDII on diesel passenger vehicles didn't come into effect until 2005.

All the Td5 Disco 2's have a small number of PID's available via OBD-II, with no appreciable difference between 1999 and 2004:

Mode 1
- Trouble codes and on board test information
- Calculated Load Value
- Engine RPM
- Vehicle Speed
- Absolute Throttle Sensor position

Mode 2
- Freeze frame trouble code

That's it.

Based on posts on OBDII tools in the Diagnostic forum, Defender Td5 owners have little success with accessing fault codes using OBD-II tools, so it's unlikely you'll get any PID's either.

So defenders up to 2005 were not OBD II compliant? Does this mean that my 2006 td5 will be, and that I will be able to get various other readings?


Thanks
