Interestingly enough, a thermometer is not part of the Land Rover Defender’s standard configuration. For mere safety reasons, the VDO outside temperature gauge (part number: VDO 397-035-001C) was thus one of the first features I have fitted earlier this year.

Initially, I had placed the temperature probe behind the horn vent and above the front indicator lamp. But this proved to be ineffective as the temperature readings were always a bit inaccurate. Today I have moved the sensor into the front wheel arch. This should do the job!

Update: I have used this (very expensive) temperature gauge for about a year now and so far it works reasonably well. However, the temperature readings are sometimes a little too high due to the close proximity to the tarmac. You can easily reach temperatures above 40 degrees, which exceeds the measurement range. Also, the gauge is losing a bit of paint already. Considering this as well as the price and limited measurement range, I would not buy it again.
