Considering you have fault code 18308 - Coolant Fan Control 2 P1900 - 004 - Open or short to ground I would be more inclined to believe it's the fan control units fault, they do fail occasionally, unfortunately they come together with fan and dealer does not sell them on their own. Check the temperature readings in VCDS if they all seem OK it will probably be the fan control unit. You might also be able to check fan duty cycle in measuring blocks in VCDS.
