If it's a generic VAG item then it may in the same place as our Skoda Octavia. Under the aeriel itself, accessed by removing the roof lining. On the Skoda it is a common fault as water ingress causes corrosion on the PCB. I've been advised to blather the new one in non-capacitance gel before fitting to try and prevent further failure.

Its under a piece of trim top of rear screen. Removed it off the rear screen, cleaned the contacts and re-fitted it and the DTC went away saving myself £140+ labour.
