Hi I have just got my car back from the garage... It has just had a 2.7 conversion carried out and I'm slowly running it in...
But my OBC now doesn't show MPG readings or AVG speed I'm just wondering if there is a reset anywhere..

Thanks

Lui

Hi Lui

If I remember correctly to reset the OBC:

First, press CODE button, and then press the small recessed button on the lower right of the unit. Keep it pressed and then the LED in the M MPH button will flash once, and the OBC is reset. Youl have to then reset the date and time etc as all memory is wiped clean.

If the above does NOT work, try disconnecting, then reconnecting the OBC with the ignition on.

I did this by pulling the yellow plug from the instrument cluster, whilst the cluster was out and the rear accessable, obviously .

You can check the condition of the little batteries whilst you are there.
