"My E300 Turbodiesel is showing an outside temperature of 46ºC. I’m not sure, but I don’t think it is really just quite that warm outside at the minute, but you never know. Coincidently, the aircon has gone too. It simply just doesn’t work. Are the two events connected? Is it an easy fix? Is it likely that the gas has escaped or is this something that just breaks down after 150,000 miles. It is 158,000 at the moment."
 
The OTG is likley to be the sensor or a wiring fault.

The aircon gas has escaped and needs investigating and refilling. Sometimes condensors rot through due to debris behind the fan cowl trapping moisture.

If there is nothing obvious have the system gassed with added dye.
