Hello, someone has an idea how to retrofit a cooling water temperature indicator without much effort and is able to comfortably. This should be in a VW Polo V 6R, 1.6 TDI BJ 2012. This vehicle unfortunately does not have a cooling water temperature indicator from the factory. Maybe this can be realized with a favorable digital installation thermometer in the area of the center console. e.g. something like this: https://www.amazon.de/…/?… Is the display exactly enough if you have the temperature sensor (only) with a hose shell I am looking forward to your opinions and ideas , maybe someone has already installed it like this or something and can report on its ejections. Thanks Greeting Horst
