to set these, you need to go to central elecs in VCDS, cant remember which byte or bit it is without plugging her in
it is under 'parking light dimming' and will be set at '0%', have a play with dimming but I run 100%
it has nothing to do with USA or scandanavian drl's because thats where I went wrong
HTH, if your still stuck then I will jump in the motor and take a look
