Thanks Marcin
Just spotted your reply.... I sat on the M25 a couple of weeks ago and until I hit traffic around heathrow the temperature sat quiet happily at at 21C for most of the drive from Dorset. However by the time I got to the M4 junction having crawled around from the A30 junction the temperature on the display had crept up to 33C. Once on the move past the M40 it dropped back down to 21C.
This suggests to me at least the sensor, wherever it is get saturated with air in the engine bay rather than airflow through the ducts. Very confusing.
