you can turn it off, but how are you going to run aftermarket/DRL when you have disabled it?
If you mean you want the parking light function then definitely yes disable DRL, and purchase euroswitch. You can do this through vag-com in central electronics coding. Also you can go to the dealership, make up excuse and "usually" they will do this for you. I cannot speak for them all but 3 places around me in Dallas, and where i used to live in Chicago would not charge to disable.
