Hi everyone, I have done a search for rear light bulb change and have found a load of posts, but unfortunately, all of the instructions seem to be the same as the ones found here (with photos): http://www.jmaguire.com/blog/2006/02/05/stoplight.html I'm not sure if the a4 has a different method to the a4 Cab, as unfortunately, mine doesn't have a little 5p size flap to open, but a big plastic disc (almost the size of a tax disc) that you twist to access the screw. I then unscrew the black plastic cylinder from around the screw that supposedly holds the light housing in place, but even with it removed, the main light unit won't pull out. There is a tiny bit of give, but it's definitely attached somewhere else that I don't seem to have access to. Does anyone have any ideas? I don't like the thought of having to pay £30-40 just to change a bulb. When I have headlights on, the rear passenger side only has the small red light visible, so it's the larger red light I'm trying to change. FYI, It's a 2005 55 a4 cab model. Thanks in advance.
