I had mine go on my 500X. I think it’s the same on the Tipo. It’s the little lump on the underside of the left door mirror. It showed the wrong temp during cold weather and affected my aircon. The whole mirror was replaced under warranty. They said the little sensor was not separate to the mirror assembly.

Is it crucial to anything in the car if I don't sort it? Don't fancy cost of a new mirror!
I put on of these into a family members 500l had to cut and solder however
Worked fine after can't find one for a Tipo however had to drill a new hole as the old one was bonded in

It made my aircon /heating on auto mess up the temperature. It was giving out a false temp so made it work either too hot or too cold. It’s only a little sensor yet can’t be separated from the mirror assembly. All it needed was a couple of connectors and a thread and sensor could be easily replaced. Putting aircon to manual seemed to cure it but it was covered under warranty so that’s why it was fixed.

If I take the mirror off am I unlikely to be able to repair the sensor?
Yup nothing to repair the the sensor it's a moulded plastic lump
You could try one of those universal sensor cut and spliced into the mirror wiring should work okay although it may be a few degrees out

Ah ok, might have to just pickup a whole unit then!

Has anyone removed the mirror unit? Can't see an obvious way to take it off!
The glass or the whole unit?
The whole unit is probably bolted in from behind the door
Possibly need door cars taking off
OP

Whole unit....oh if it's door card, anyone taken one of these off and can provide pointers?

Has anyone removed the wing mirror glass off a Tipo, will it just pop off with a trim removal tool behind it?

Most mirror glasses I’ve taken out normally just pop out with a good tug, can be a bit stubborn, often have metal locking tabs that come out at same time. Sure there’ll be a youtube video somewhere or one for a similar model

Cheers, struggling to find Tipo specific videos but lots on 500/x so hoping will be similar!

Ok I've managed to pick up a new sensor and thermistor off eBay and swapped them over today. I now have a temperature reading but it's way off! It's about 4c out but it's reading 34c would I need to reset something or have I b3en sold a lemon. I've contacted the seller but don't expect a reply as it's the weekend...

Mine failed recently but then came back to life for no reason at all.

Mine was dead a couple of months so might be a sign yours doesn't have long left!

Got a replacement sensor off the eBay chap as assumed first one is a dud but it's exactly the same about 30c higher than actual temperature. Beginning to think it could be the wrong one unless anyone knows if there's a reset or calibration sequence? I disconnected battery for 15 mins which I thought may help but no difference! Surely can't be this difficult
