1. Walk around the front of your BMW and open the hood.
2. Locate the fuel injectors on top of the engine. You will see one injector per cylinder--four injectors on the left and four on the right.
3. Grab a piece of paper and pencil and write down the numbers 4, 3, 2, and 1 on a single column to the left of the paper. Make sure there is some space on top and bottom of this column.
4. Write down the numbers 8, 7, 6, and 5 on a single column to the right of the first column of numbers.
5. Write down the word rear on top of the two columns of numbers, and the word front at the bottom of the two columns of numbers.
6. Grab your piece of paper with the two columns of numbers and stand in front of the engine, facing the drive belt. If you look at your notes on the piece of paper, the two columns of numbers represent the cylinder numbers in your BMW 740i. The word rear represents the back of the engine and the front represents the front of the engine, which you are facing right now.
7. Label each of the fuel injectors using a piece of masking tape and a black marker, according to the numbers you have assigned to the each cylinder.

1. Drive the car somewhere out of the way, or tow it if the wastegate is broken. Driving a turbocharged car with a damaged wastegate can seriously damage the turbocharger and the engine. Place the car in park and turn off the car. Pull the hood release latch and then prop the hood up with the prop stick. Disconnect the black wire from the car battery to ensure that the cars circuits are dead.
2. Locate the wastegate valve on the turbine side of the turbocharger. The wastegate is a small metal valve bolted onto the turbochargers exhaust feeder pipes. Disconnect the control wire from the wastegate and place it to the side. Use a wrench to unbolt the two bolts that secure the old wastegate to the turbocharger. Pull the wastegate out, being careful not to scrape the sides of the hole.
3. Slide the new wastegate into the hole on the exhaust feeder pipe. Slide in the bolts and screw them down by hand. Once both bolts are down, wrench them down flush with a wrench. Plug in the control wire into the side of the wastegate. Make sure there is no packing material stuck in the valve. Reconnect the black wire on the car battery and then shut the hood. Turn on the car and take it for a test drive.

1. Shut the engine off and remove the key from the ignition cylinder. Step out of your ML-320 and close the door.
2. Press the "Unlock" button on your keyless entry remote. Grasp the edge of the fuel filler door and pull it toward the front of the ML-320.The fuel filler door locking mechanism is controlled by the keyless entry remote. If using the remote does not unlock the fuel filler door, the system may be malfunctioning. Proceed to the emergency release procedure.
3. Open the rear cargo hatch. Locate the plastic cargo door on the drivers side of the cargo compartment. Turn the two knobs counterclockwise to remove the door and access the fuel filler door lock rod.
4. Turn the lock rod counterclockwise to line up the arrows. This will manually unlock the fuel filler door. Pull it open with your hand.

1. Pop the hood of your BMW and disconnect the battery terminals. Sit in the drivers seat and lower the steering wheel to its lowest position within the steering column.
2. Locate the bezel around the outskirts of the instrument cluster. This can come in either plastic or rubber. Remove the two screws attached to the bezel with a Phillips screwdriver. Pull the bezel out of the dashboard.
3. Remove the three mounting screws which fix the instrument cluster to the dashboard. Slide the panel out and remove the battery connector from the rear. You can either pull it out with your hand or use a screwdriver to pop it out.
4. Pull the instrument cluster fully out of the dashboard. Clean the space left in the dashboard with a cloth to ensure there is no dust or debris, which can get into the instrument cluster.
5. To reattach the instrument cluster or insert a new one, install the cluster following the removal steps in reverse.

1. Park the ML430 on a flat surface and make sure the engine is cool. If the car has been driven recently, wait at least 30 minutes for the heat to dissipate. Raise the car on jack stands to reach the underside of the engine more easily. Slide under the car and locate the transmission drain pan. It is a large, metal tank held with eight bolts beneath the middle of the engine.
2. Place a collection pan beneath the drain pan. Use the 1/2-inch socket wrench to remove all but one bolt on the drain pan. Wait 10 to 15 minutes for the fluid to drain into the collection pan. When it stops spilling from the side, place one hand on the drain pan and remove the final bolt. Lower the pan and pour the remaining fluid into the collection pan. Wash out the drain pan and bolts.
3. Remove the transmission filter under the drain pan with the 3/8-inch socket wrench. Attach the new transmission filter with the same bolts removed from the old one. Reattach the drain pan and lower the car from the jack stands.
4. Pop the engine hood by pulling the hood-release lever underneath the steering panel. Locate the yellow transmission dipstick above the drain pan. Pull it out and place a funnel into the tube. Pour in three quarts of five-speed transmission fluid. Replace the dipstick and close the engine hood.
5. Pour the used transmission fluid into a leak-proof container and take it to a recycling center. Many auto repair and auto parts shops also accept used car fluids.

1. Lift the hood of the car and locate the wiper motor, which is located on the driver side of the car, directly underneath the windshield wipers. Remove the wiper motor´s plastic cover by loosening its fastening clips -- this can be done by hand. Locate the bolt in the center of the wiper motor, remove it with a socket wrench and set it aside.
2. Run your windshield wipers through one complete cycle (the easiest way to do this is to activate the windshield washer, which runs your wipers through one cycle and then stops them in the parked position). This will not actually move the wipers, as the wiper bolt is removed, but you will notice the motor moving.
3. Push the wipers down until they are in an all-the-way-down position. This will hide the spot where the wiper bolt was attached -- the passenger wiper linkage will conceal it from view.
4. Pull the passenger wiper linkage away from the wiper motor. Use your hands, but do not use too much force, as that could break or bend the linkage. With the passenger wiper linkage removed, reattach the wiper bolt to the wiper motor, and make sure that the driver side wiper linkage is still in the all-the-way-down position before reattaching the wiper bolt.
5. Turn on your windshield wipers to confirm that they have been correctly reset. Only the driver-side wiper will move at this point, but because the wipers work in tandem, a correctly positioned driver wiper indicates a correctly positioned passenger wiper.
6. Reattach the passenger wiper linkage to the wiper motor. Use a mallet to tap it back into place, reattach the wiper motor´s plastic cover by tightening its fastening clips and then close the hood. Run your wipers again to ensure that both are correctly reset.

1. Remove the coil pack cover with a ratchet. The cover is held on by six bolts.
2. Unplug the coil that needs to be replaced.
3. Remove the coil with a ratchet. The coil is held on by two 10mm bolts. Once you have the bolts removed, pull firmly and the coil will come out.
4. Install the new coil and tighten it with a ratchet.
5. Reconnect the coil connector.
6. Attach the coil pack cover back onto the valve cover and tighten the bolts with a ratchet.

1. Drive the 325is to your garage or a parking lot. Turn the fan on and feel for any air coming out the vents. If there is no air, then the blower motor needs to be replaced. Put the 325is into Park, then engage the parking brake so there is no danger of gear slippage during the repair. Make sure you have room to maneuver around the front of the BMW for the removal process. Turn the BMW off and open the hood and trunk.
2. Go into the trunk of the BMW and disconnect the negative battery cable from the cars battery. The battery is located in the trunk of the 325is for better weight allocation. Go around to the front of the 325is and prop the hood up with the hood prop stick. The blower motor assembly will be mounted with six screws against the rear firewall. Remove the screws with a Phillips-head screwdriver and pull the blow motor assembly off the firewall.
3. Press the pressure clips on either side of the motor and pull the motor from the blower assembly. If the blower motor has burnt out, then there will be a smell of ozone in the air. If the fan has broken, then some of the blades will be snapped off. In either case the blower needs to be replaced. Disconnect the power wire from the rear of the motor and then connect the power wire to a new blower motor.
4. Slide the blower motor into the blower assembly until you hear the clips click. Then screw the assembly back on the firewall. Tighten all the screws down by hand, as high-torque power drivers could crack the assembly. Close the hood and then go around to the trunk to reconnect the negative battery cable. Close the trunk and then turn the BMW 325is on. Turn the fan up and feel for any air. If there is no air flowing, then the power cord was not plugged in flush. Take the blower motor out and reseat the power cord.
