Hi, I also want to replace my lock, but I cant get the old lock out. I have removed parts 7,8,12 as shown on the picture, but I still cant get the lock out. Im also curious to know, what was on the other pictures, they might have helped and where are these pictures taken from, Autodata? I´ve read that there are also supposed to be some clips under the exterior door handle, is that true? I cant find them on my car. I have a 97´ A4.
