I can't open the trunk in my 2003 VW Jetta. After taking apart the trunk hood, I've determined the problem is the same as described in this thread, but I cannot find the replacement part. This thread mentions a part number for the trunk latch, but the latch isn't what's broken... the part that's broken is the black plastic "arm" (pointed to in the photo by the caption 'Broken arm').
Searching Google and various parts web sites has not gotten me anywhere. What is this part called?
