Rain sensitive wipers

[drew baby]

Hi all,

After last weeks nightmare with the hailstones the size of golf balls I've had a new windscreen fitted, the rain sensitive wipers ain't working, the handbook says I need to go to the dealer and have them re calibrated is this something that can be done using VCDS or is there more to it
Obviously far to hard to just be able to change the screen an carry on lol
