I have fitted tow bar electrics to my VW car. The electrics include a
box which is connect to the CAN bus.

To work properly the car has to be re-programmed. A local VW garage
said this would take an hour, based on recent past experience. Even a
place which specialised in this work said it would take half an hour.

Why on earth does it take so long? I was thinking that it would just be
a five minute job clicking a few screens.
