Park Brake Fault Light After Fitting New Rear Pads

[Antipodean]

Hi folks.

Had the Parking Brake Fault Light come on after changing the rear brake pads (2010 Tiguan)

Did the mechanical wind-out of the electric motors.

Brakes themselves are working fine - its just the Fault Light, and it's impact on the operation of the Park Brake. The Park Brake worked fine before I changed the pads.

Thought it might just need to have the code cleared, but my OBDII/EOBD reader doesn't seem to work with this car (I go it from ALDI - I know, I know...)

Am I on the right track with just needing the code cleared? Or is there something more sinister at play here?

Cheers
