Please help. Headlight bulb good but does not light. Bought Ballast ($500) and that is wrong say I need headlight control module that goes behind glove box. Can't find anywhere even Audi dealer says everything for headlight repair is in headlight assembly (not what mechanic says he needs).

 

What model? I have on 01 Allroad, the module was located in the left rear quarter panel just in front of the CD changer. I had to remove the panel to get to the module, however I did not realize that this module could also control the lights illumination or not, mine was needing to be replace because it did not allow the headlights to auto-level anymore.
