Great thread, an addition for you guys who have slightly different door cards e.g 56 plate sportbacks
Remove trim around central locking switch. No best place to start, just go easy with a plastic blade. This gives you access to upper torx bolt.
Upper face of door card pocket, has a hole in it where you access middle torx bolt. No trim removal needed to access this.
Lower Torx bolt on lower edge of door card is located in same position as with door card earlier in thread.
Start popping door card away from door starting at speaker working around bottom of door to the catch area. (you can see clips in image below)
Image showing door with clips in situ. Note blue clip at 7 0'clock on the speaker. Hard to get with camera
Bottom right blue clip on door panel gave me problems and bust the mounting point in the door card, despite having trim clip lever! (Super glue with extra epoxy glue coat, got us back on track)
Notice that to make life more interesting for the bodyshop guys Audi changed the colour of the clips.
IF any of you have an annoying rattle from your door that disappears when you apply slight pressure to your door handle then it is probably the captive nut for the middle torx bolt. If you are lazy then, with the door card in situ, remove middle torx bolt, squeeze some black or translucent silicon sealant through the hole in the door card for the middle torx bolt. This will probably solve it and save 90 mins of labour.
Have fun.
