Temperature gauges.

Hello there!
I am wondering which part do i have to replace in order to fix my engine temperature gauge on the speedometer and also the general outside temperature shown on display.
Thanks

Display temperature is a €5 sensor behind the bumper. May also be a wiring fault as the bumper loom does get the worst of salt, spray and muck...

Gauge temperature is a €5-10 sensor which bolts to the coolant bridge. Again this might simply be that the spade connector that locates onto it has simply slipped off... Check this first. Do not confuse this with the ecu coolant temperature sensor with a Bosch plug.

Also, if you ground the blue wire that goes to the engine temp sensor, the gauge should go to fully hot
