Today I noticed a broken wire on what's seems to be a sensor located on a hose connected to the bottom of the radiator on the left side of the car (see pictures). (2015 A5 sportback 1.8T)

First I want to know which sensor is it and then the easiest and proper way to disconnect the connector in order to repair it.(do I have to push, pull, lift any tab, etc).

Hopefully I may disconnect it with one hand from the top and not having to lift the car, remove the pan, etc.

Thanks

Looks like the coolant sensor. Press down on the tab and pull it backward. It will probably be a bit tight and sometimes helps by pressing down the tab and pushing forward before pulling it
