I need to replace my temp sensor plug and wiring as mine has snapped at the plug and badly corroded. I have this part number but can't get a definitive answer if its to fit my fabia?

Part number will be on the existing connector housing, in tiny form, somewhere.

Cheers I'll take a look

@daz_vrs I just looked up the part number you suggested, and it's a 3-pin housing that would fit the radiator (dual) thermoswitch, rather than a temperature sensor, is that the one you are after?
