tempature on trip computer

[jonny83]

hi there new to the forum. i have a tdi 130 ( 02 reg) and over the last few days the temprature read out on the trip computer has gone carzy! haha when i start up the car it reads about -40 to -50. and it aint that cold in sunderland! whist diving it might go up to about 9, witch is about right. then it will drop, rise, drop, rise and so on. anyone seen this before? any clues? thnx.

Dodgy wiring to the sensor would be my first thought, next is dodgy sensor.

Just check the sensors wires like Jay said. The sensor should be behind the passengers side vent on the bumper. It may even be unplugged.
