1.
A powerful flashlight will help to locate motor mounts in difficult-to-see areas.
Block the wheels with the wheel chocks to prevent movement of the vehicle either forward or backward. Raise the hood of the vehicle and use the flashlight to locate the motor mounts. Motor mounts will be located in various locations above and below the engine and transmission depending on the specific model.
2. Examine the motor mounts for signs of damage. The rubber blocks in the motor mounts can crack, split, or show other damage that will require replacement. Examine hydraulic mounts for signs of fluid leakage, corrosion or other damage. The mounting plates that secure the mounts to the vehicles frame may also corrode or break.
3. Have the assistant start the vehicle. While you stand off to the side of the vehicle to observe the engine, have the assistant depress and hold the brake pedal and shift the car into drive. Watch the engine for rapid or excessive movement. The engine should move less than ½ an inch when placed into gear. A banging noise may also be a sign of a faulty motor mount.
4.
Shifting the car between drive and reverse will cause the engine to move.
Have the assistant place the vehicle in reverse and again watch for movement or noise. Have the assistant place the car back into park and turn off the vehicle.
5. Use pry bar to flex motor mounts. Any looseness in the mount will require replacement of the motor mount.
6. Use the pry par to check for play between the motor mount and the mounting surface of the engine or transmission. Play between the motor mount and mounting surface may be a result of bolts that come loose.

1. Create a grounding apparatus for the diagnostic connector. Attach the copper clip to the large end of the insulator. Connect the copper wire to the skinny part of the insulator. Connect the other end of the wire to a banana plug. Connect the wire on the BMW pin to the other side of the banana plug.
2. Turn the key in the ignition half way so that the lights come on but the engine is not running.
3. Open the hood and locate the ground plug in the electrical system near the engine. It is usually a small octagon shaped screw or nut close to the data link connector. Attach the open side of the copper clip to the ground plug.
4. Locate the data link connector and unscrew the cap exposing the pins underneath. Press the end of the male pin into the number 7 plug inside the data link connector. This is usually the middle right hole on a 15-point connector and the very bottom hole on a 20-point connector. Hold the pin in place for three seconds to reset the oil light, and nine seconds to reset the inspection light.
5. Remove the pin once the light resets. Screw the cap back on. Turn the engine off, then turn it back on. If the lights are still there, try resetting the lights again. Once the lights remain off, turn off the engine and close the hood.
