Thank you,
Will need to find some free time now to work on the car.
I will probably purchase new temp sensor anyway before getting my hands dirty :) they are not very expensive.
I am also thinking about buying Xtool VAG401 to be able to do diagnostics. Always want to get one but did not have any major issues so far.
Now could be useful to sort the radiator-fans and air-conditioning i am sure it will be useful in the future :).
And still not sure how the main fan is being controlled? Temperature sensor must be connected to control unit which is giving the signals to operate both fans through relay's.
I should probably ask this question in schematics section of the forum but much appreciate if someone could provide with wiring diagrams including connections to control uni.
Thank you for your support.
