I recently took my 2006 A4 to Pepboys to have the headlights changed. They got into the car and called to tell me they were not able to change the bulb because they were unable to disconnect the existing bulb from the headlight. I was told once the mechanic checked there was a special tool needed to remove the bulb that only dealers can get. He did mention he had changed bulbs before on A4's but had never seen this. Does anyone know what he might be talking about, or was he mistaken. I would prefer not to have to go to the dealer to have this done, as they will undoubtedly be much higher in cost. Any help would be appreciated.
