How Do I Dismantle the Front Door of an Audi Quattro?

1. Roll down the window on the door of which you are removing the door panel. This will allow you to lift the panel out of the track.
2. Locate the screw cover plates on the bottom and sides of the door panel. They are well hidden, but you'll notice them if you look closely. Remove these cover plates with a flat screwdriver and place them in the Audi's cup holder for safe keeping.
3. Pull the interior door handle to remove the screw cover plate. Remove the screw, and then wiggle the door handle trim plate until it comes loose. Pull it away from the door handle and set it aside.
4. Remove the door mounting bolts on the bottom side of the door's arm rest with the socket wrench.
5. Wedge the door panel removal tool between the door panel and the door itself. Use the tool to pry outward on the door. The door panel is attached using ribbed plastic fittings that will pull out as you work the tool around the door. Do not attempt to use a screwdriver to do this; you will damage the door and door panel by doing so.
6. Reach up under the door panel and unplug the electrical wiring harness for the window switch and door lock switch.
7. Hold both sides of the door, pulling it far enough away from the door itself that the plastic ribbed fittings do not catch on their mounting holes. Wiggle the door panel upward slowly to release the door panel from the window track.
8. Pull the sound proofing pad off the inside of the door, being careful not to tear it. Underneath, you will find access holes that will allow you to remove damaged parts of the door.
9. Remove the side-view mirror by locating the bolts exposed in a series of three holes at the front corner of the door. Remove the wiring harness from the large hole in the middle of these three holes. Remove the bolts with the socket wrench.
10. Remove the window regulator motor by reattaching the switch on the door panel to its wiring harness. Close the window. This will give you complete access to the Audi's internal door components. Unbolt the motor from the window track and pull it straight out of the door. On some models, this will cause the window to lower, so hold the window when you're pulling the motor out. When it is out of the door, disconnect the wiring harness from the motor.
11. Remove the door handle by reaching up inside the door and disconnecting the steel connecting rods from the door handle. Next, use the socket wrench through the two access holes on the inside of the door to remove the door handle mounting bolts.
12. Remove the entire front door by opening the door all the way. The two hinges for the door have a C-clip holding the hinge pins in place. Disconnect the wiring harness from the nearby wiring connector, remove the C-clips, then use a hammer to gently pop the hinge pins upward out of the hinge. Have an assistant hold the door as you remove the pins to avoid damage to the front fender or the door itself.
