Is it possible to fit the driver info diplay to my a4 which doesnt have it fitted?
If so which bits would i need to change?

Thanks guys

 

you need to buy a new wiper stalk, that has the fuction to switch.
you will need access to a vag com to change the setting on the car

you will need to either ground the wire for the windshield washer fluid OR buy the wire and sensor and run to car.

then you are done
