The Interior Display has suddenly started showing an incorrect temperature. yesterday 50.2 degC !! and today 18.5 deg C when I know its 9 deg C outside. I'm thinking the connection to the sensor may be dodgy, or I may have to replace the sensor. Haynes Manual no help!

its under front bumper on pass side near front, a little black thing with a plug going into it.

Easily accessible on F/L below the washer bottle. Just pop the bonnet and reach down

that assumes that the OP's car is a very very early facelift because it's described as a 99 car

Never had the far inferior pre facelift hence my post being a facelift one

Iirc, m/fl cars have been '00 W, and F/L cars have been '99-'00, so wouldn't rule it out

but we Pre-facelift owners like the interiors to stay as it was originally intended

Mini facelift cars are from S reg (or maybe R reg) to very very early W reg

Never really liked the earlier interiors tbh Remind me of the Vectra B, and I never really liked them either

Doesn't alter the fact that the outside temp sensor lives in the front bumper somwhere below and behind the number plate. How you access it depends on whether your car is pre (grill in bumper) or post (grill in bonnet) facelift As said post facelift nice and easy

Its mounted behind the passenger side fog light

So presumably, pop out the fog light and reach in

No need, stick your hand underneath the front edge of the bumper.

Thank you for all the replies but I'm still struggling to find the outside temperature sensor, after following them, to clarify, my Omega is a 1998 model first registered 1999 and it has a grill which lifts out. I have removed it, and centrally is the windscreen washer reservoir, nothing else.
If its behind the passenger side foglight  do I just remove the small grill and pull the light forward, as I would to change a bulb? or do I have to remove the bumper for access? I have a pit but from underneath I see nothing obvious.
regards

It's clipped to the lower edge of your bumper, passenger side.

Mine was pushed through a rubber grommet in the bottom lip if the plastic bumper.

Hi Guys, I'm sorry to be so thick! i have now FOUND that damned temperature sensor!! It was'nt so difficult after all!
The wiring looks ok and I see plenty on Ebay about £3.+ so I am now ordering one.
I did get a glance at a Vauxhall Worksop Manual for Omega B and I see how to 'break' the front clip to remove the sensor, etc.

Thank you all for your patience and help
