At 130 hours the Check engine light started flashing. I put my OBD Reader on it and it showed Alarm P1801, called my dealer and they could not give Me any information except the standard bring it in. So I loaded it up and carried it to the dealer. Basically it needed to be reflashed with Mahindra update.
Now temperature and glow plug indicators work correctly.

Yeah my temp gauge didn't register at all before the ECU was reflashed. Mahindra needs to come up with a better way to do this. There is absolutely no need to haul a tractor in just to reflash the ECU. Reflashing automotive ECUs are done on cars all the time via the same OBDII port.
