1. Open the drivers side door as far as it will go and locate the triangular cover secured to the inner door panel. The cover is located directly opposite to the spot where the mirror is attached on the outside of the door.
2. Pull the access cover off the inner door panel, using your fingers.
3. Pull the wiring harness out of the inner door and disconnect it.
4. Remove the three bolts that secure the mirror to the door frame, using a socket and ratchet.
5. Pull the mirror straight out from the door to remove it.

1. Place one of the keys in your right hand. Each key has three points to it, and you want to pick the one with the 45-degree slant at the end. Locate the slot at the bottom-right corner of the stereo, and place the key so that the flat side of the key goes towards the passenger side of the car. Push the key into the slot until it clicks into place.
2. Repeat step 1 with the second key, but flip the key around so that the flat section is pointing towards the drivers-side door.
3. Pull the inner spoke on the key on the left side of the stereo towards the drivers side door, and pull the stereo out of the dash. Unplug the wiring harnesses from the stereo using your hands, and disconnect the antenna lead as well.

1. Disconnect the negative battery terminal first using a wrench. Engage the parking brake. Slide a drain pan underneath the gas tanks drain plug, before removing the plug and allowing all of the gas to drain out.
2. Remove the bottom seat cushion, then remove the covers on either side of the seat. Raise the rear of your car with a jack, placing a the car onto a pair of support stands. Detach the rear muffler section and driveshaft before attempting to remove the gas tank. To do this you will have to loosen the bolts holding the various components (ie. driveshaft and rear muffler section) into place. Spraying some penetrating oil onto the bolts may make it easier to remove them.
3. Detach all fuel lines connected to the tank using a specialized BMW fuel line removal tool you can find at most auto parts stores. Place another jack beneath the tank as you remove the straps holding the tank in place. The straps are secured with bolts on each end, which you will have to loosen with a socket wrench. Once youve removed all the straps and bolts, the tank will drop onto the jack.
4. Detach all fuel lines, filler hose and fuel pump from the tank while it sits on the jack. Perform any necessary repairs or replace the tank by reversing the previous steps. Finally, lower the car from the support stands and refill the gas tank.

1. Open the hood, and secure it. Look behind the headlight you are working on and find the plastic release clip behind the turn signal. Slide this clip forward, remove the turn signal and put it aside.
2. Remove the filler panel located just below the headlight assembly by removing the two screws that hold it in place using a screwdriver. Put these screws aside.
3. Find the black plastic filler panel connected to the headlight assembly, and remove the bolts that hold it into place. There will be two bolts on the top part and one or two on the bottom (most likely 8-mm bolts) depending on the year of Mercedes 300E you are working with. Place these aside.
4. Disconnect the wiring connectors at the back of the headlight assembly. Remove the headlight assembly and gently set it down.
5. Locate the plastic clips that hold the headlight lens in place. Push these clips up gently with your fingers and remove the headlight lens.

1. Open the door and remove the bottom seat cushion from the car using the 3/8-inch ratchet, extension and sockets. Unbolt the covers located on both sides of the area underneath the seat using the ratchet.
2. Unbolt the fuel level senders on the sides of the tank using the ratchet. Then lift the rear of the car using the jack and set it down onto a pair of jack stands.
3. Unbolt the rear muffler section from the car using the 3/8-inch ratchet, extension and sockets, then lower it out of the way. Unbolt the driveshaft from the rear end of the car using an open-end wrench.
4. Place the jack underneath the gas tank. Unbolt the gas tank from the chassis using the 3/8-inch ratchet, extension and sockets. Slowly lower the jack to drop it down from the chassis. Disconnect the fuel lines and connections from the tank using a flat head screwdriver.

1. Sit in the back seat of the vehicle, facing the front seat, and press the electric switch on the front seat to raise the headrest to its highest setting. Set the front seat in a completely upright position.
2. Push the headrest release button, located under the upholstery on the back of the front seat about 11 inches below the left headrest pole. If you do not feel a release button, skip to Step 4. Some newer models do not feature a headrest release button and require a different method of removal.
3. Push the headrest release button and slowly pull the headrest out of place until it is removed.
4. Enter the front seat, facing the seat-back.
5. Place both hands on the two headrest bars. Move them back and forth as you pull them up, which will release the headrest latch. Remove the headrest from the seat.
