Hi there,
just started the engine and get fault on a dashboard - 4WD error, temperature too high. Now is winter here, car wasn't used for couple of days.
4WD sensor got broken?

Specifically what year / model / drive-line accompanyment?

Have you scanned for error codes and what was the resultant code (or codes) by number?

It's 2016, LY, 1,4 Boosterjet, AWD. Registered to workshop, but it will be only next year, on Wednesday.
Logically, if it gives error code - AWD off, cause temperature too high on cold vehicle, it should be sensor or wiring i think. Main reason for question - can i drive this car till next Wednesday

If it’s a faulty sensor it should be ok to drive. It’s just disabled AWD to protect the system. You get a proper red symbol and message for a “stop now” fault such as no oil pressure.

It was rotten wires near temperature sensor in rear differential and sensor itself got shortened. On -1 Celsius it showed 64C degrees.

Glad it’s resolved and proved to be nothing serious.

You‘re also lucky it’s not a LandRover - there’s a fault on the last Discovery 4 and RRS where a sensor reads higher temperatures but, unfortunately, it‘s also used to determine how much heat to pump into the cabin to meet the temperature set by the driver. Unfortunately, it’s not as simple as the HVAC temperature sensor as it involves something like the difference between the external temperature and the set cabin temp, dividing it by the number of times the car broke down last month, multiplied by the chances of being hit by a comet.

There are a lot of freezing LR owners at this time of year.
