Troubleshooting a 1997 BMW 528I Fuel Pump


1. Watch for your 528i to exhibit signs that the fuel pump is not working properly. Two key signs are the car refusing to start when you turn the ignition key and the engine stalling when you press the accelerator pedal to increase the BMW's speed.
2. Listen for the fuel pump to begin working when the BMW's battery is energized. Put the ignition key into the ignition and turn it one setting to the right so that the car's battery is on. If the fuel pump is working properly, it will begin sending fuel through the fuel lines as soon as the battery is working. You should be able to hear the pump from the driver's seat of the car. Be sure to perform this test in a quiet place or, if you are unsure whether you hear the pump working, have a second person turn the key on while you stand by the gas tank and listen.
3. Connect a fuel pressure gauge to the Schrader valve of the engine and check the fuel pressure of the car. The Schrader valve is near the top of the engine and looks very similar to an air valve on an automobile tire. Once the fuel pressure gauge is connected to the valve, turn the BMW's engine on and let it idle. Read the gauge to see if the car has the proper fuel pressure level. A 1997 528i should have between 51 and 58 pounds per square inch of fuel pressure in its fuel system.
4. Inspect the fuel pressure regulator to see if it is working properly. When the fuel pressure is too low on your BMW, the regulator may be faulty instead of the fuel pump. Leave the fuel pressure gauge attached to the Schrader valve and turn the engine on so it is idling. Gently squeeze the black fuel line running to the fuel pressure regulator and watch the fuel pressure gauge at the same time. If the fuel pressure increases while you are squeezing the fuel line the fuel pressure regulator needs to be repaired or replaced instead of the fuel pump.

DIY Audi Quattro A4 Brakes


1. Loosen the lug nuts that hold the wheels on using a lug wrench or a socket of the appropriate size and a ratchet. Use the floor jack to raise the car. Slide jack stands under it at the appropriate points and lower the car onto the jack stands. Finish removing the wheels and put them aside.
2. Open the cap on the brake master cylinder to avoid building up pressure in the master cylinder during the brake pad change. Remove about half of the brake fluid in the master cylinder with a baster or syringe.
3. Start at the front of the car. Remove the large spring clip on the brake caliper by prying off both ends (which are hooked into the caliper) with a pair of pliers. Remove the two black plastic caps on the back of the calipers with a flat-head screwdriver.
4. Remove the two 7-mm hex head screws under the plastic caps. Slide the caliper off of the rotor without damaging the ABS sensors and the brake lines.
5. Remove the pad from the inside of the caliper by pulling it straight out. It is held in with a three-pronged clip that fits inside of the caliper piston. Remove the outer caliper, which is not held on with anything once the caliper is removed. Support the caliper with a piece of wire or on a box so that there is no weight on the brake line.
6. Remove the two 17-mm bolts on the back of the rotor that hold the caliper carrier on. Remove the caliper carrier. Pull the rotor straight off of the hub. Spray the rotor-to-hub mounting surface with brake fluid and wipe it down with a clean rag.
7. Spray brake cleaner on the new rotor and slide the rotor onto the hub in the reverse order by which the old one was removed.
8. Install the new pads in the caliper in the reverse order of removal. Test fit the pads by trying to slide the new pads over the rotor. If there is not enough clearance, remove the pads and compress the piston into the caliper with a C-clamp until there is enough room for the new pads to slide over the rotor.
9. Slide the caliper over the rotor. Tighten the caliper screws, replace the plastic caps, the spring clip for the caliper and then the wheel. Repeat the above steps for the other side of the vehicle.
10. Move to the rear of the vehicle. Remove the two bolts that hold the caliper on by placing a 13-mm socket over the bolts and a 15-mm wrench over the other nut.
11. Slide the caliper off of the rotor. The pads may stay on the rotor, since there is nothing holding them on once the caliper is removed.
12. Compress the caliper piston with the special piston tool. The tool has pins that fit in the holes in the piston and allow you to turn the piston and retract it. Completely compress the piston.
13. Remove the 8-mm bolts that hold the caliper carrier on. Remove the caliper carrier. Slide the rotor straight off of the hub. Spray brake cleaner on the hub mounting surface and the new rotor and wipe them down with a rag.
14. Slide the new rotor onto the hub and reinstall the caliper carrier with the two 8-mm hex bolts, tightening them firmly. Place the new brake pads onto the rotor in the same place the old ones were.
15. Slide the caliper over the pads. Ensure that the pad’s spring clips are oriented correctly, without the spring poking out of the hole in the caliper. Install the caliper mounting bolts. Repeat the above steps for the other side of the car.
16. Replace the wheels. Lower the car off of the jack stands and onto the ground. Refill the brake fluid reservoir with brake fluid if the fluid is low. Pump the brakes until they feel firm again and the pads are seated against the rotors. Break in the new pads according to the manufacturer’s recommendations.

How to Remove the Top on a Mercedes 560SI


1. Lay a blanket down in the area where the hardtop will be stored. Put the other blanket nearby.
2. Open both doors on the 560SL. Find the latches in each of the four corners of the hardtop where it meets the body of the car. The latches are set into the top of the sides of the body and are flush to the surface when in the closed position. They look similar to hard, plastic, rounded rectangular plugs.
3. Open all four hardtop latches by fitting the tip of an index finger in the groove molded into the end of each latch and pulling up to release.
4. Pull up the seat back-release lever on the driver's seat, and push the seat back down toward the steering wheel.
5. Reach behind the driver's seat, and turn the crank handle of the rear latch counterclockwise until the latch releases. The rear of the hardtop will pop up away from the car body slightly when the rear latch releases.
6. Stand on one side of the vehicle, and have a helper stand on the other side. Lift the hardtop up off the body of the car. Walk toward the rear of the Mercedes together, carrying the hardtop. Once the hardtop is no longer over the car, carry it together to where the blanket is laid down and place it on the blanket.
7. Place the additional blanket over the hardtop to protect it while in storage.

How to Replace Spark Plugs in a BMW 525


1. Use the flat-head screwdriver to gently pop off the two plastic covers, which are about the size of a quarter, that hide the bolts that secure the plastic cover over the engine head. This large plastic cover runs the length of the engine and has the BMW logo on it.
2. Remove the plastic oil-filler cap and loosen the bolts that connect the engine cover to the engine block.
3. Remove the large plastic engine cover to expose the spark plugs.
4. Remove the hex bolts that secure each 'BREMI' plug to the top of the spark plugs. The BREMI plug is the BMW equivalent to the standard boot that most domestic cars use to attach the spark plug wires to the tops of the spark plug. Remove each BREMI plug from the top of the spark plug by gently pulling it straight off the top of each plug. Leave the spark plug wires attached.
5. Use the spark plug socket wrench to extract the spark plugs from the engine block one at a time.
6. Replace each spark plug by tightening it loosely into the engine block with the socket wrench. Tighten each spark plug fully with the torque wrench to the specific torque setting listed in your owner's manual.
7. Replace each spark plug wire one at a time by removing them from the back of each BREMI plug and unplugging both ends of the wire, replacing it with a new one.
8. Replace the BREMI plugs back to their original location on the top of each spark plug.
9. Replace the large plastic engine cover, oil cap, and re-install the cover back on the engine block with the two mounting bolts.
10. Replace the two small plastic covers that hide the mounting bolts.
