How to Replace a Fuel Filter on a 560 SEL

1. Drive the Mercedes Benz 560 to a safe and well-ventilated work area that has a level surface. Make sure to set the emergency brake.
2. Remove the fuel cap from the fill tube of the fuel tank. Removing the cap will remove pressure from the fuel filter without having to remove any fuses.
3. Jack up the passenger-side rear of the Mercedes Benz 560 and set the safety stand under the frame directly in front of the rear, passenger-side wheel. Slowly lower the vehicle onto the safety stand. Leave the jack up as a extra safety precaution.
4. Locate the fuel filter behind the passenger-side rear axle. The fuel filter is a round canister with a fuel line attached to each end. Set the drip pan on the ground under the area of the fuel filter.
5. Remove the fuel lines from the fuel filter by unscrewing the fuel filter nuts with the metric wrenches. One of the fuel lines has a male end and the other fuel line has a female end. Turn both fuel lines counterclockwise to loosen and remove them.
6. Wait for the small amount of fuel to drip out of the fuel filter and fuel lines before you finish unscrewing the fuel lines from the fuel filter. Then, remove the bracket bolts from the fuel filter bracket with a metric wrench.
7. Pull the old fuel filter out and set it in the drip pan. Place the new fuel filter into the bracket. There is an arrow stamped onto the fuel filter that represents the direction of fuel flow. Make sure that the fuel filter is positioned inside the bracket with the arrow pointing towards the fuel line that carries the fuel to the engine and away from the fuel line that comes from the gas tank.
8. Screw both fuel lines onto the ends of the fuel filter. Tighten each fuel line clockwise with the metric wrenches until the lines are tight. Then, reattach the bracket and screw the bracket bolts in place. Tighten the bracket bolts with a metric wrench.
9. Pull the drip pan out and put the fuel cap back on the fill tube of the fuel tank. Turn the fuel cap clockwise until it clicks.
10. Turn the ignition key to the accessory position for five seconds and then back off again. Turn the ignition on and off for five seconds three different times. This will cause the fuel pump to fill the new filter up with fresh fuel and remove the air from the fuel system. Then, crank the engine and let it run while inspecting the new filter for leaks. Turn the engine off.
11. Jack the passenger rear of the Mercedes Benz 560 back up and remove the safety stand out from under the frame. Lower the Benz to the ground and remove the jack.

How to Remove a BMW 3 Series Windshield Reservoir

Instructions
1. Crouch next to the front-passenger wheel well and notice the bolts holding the front inner-fender well to the BMW. Remove these bolts with the socket wrench and tuck the fender well out of the way.

The Wipers Won#039;t Work on a BMW 328I

1. Put your key in the ignition and start your car. Turn on the wipers. If they do not move at all, it could be result of a blown fuse or a relay and wiring problem. Turn the car off and open your fuse box. Locate the appropriate fuse and pull it. If the fuse is blown, then replace it. If the wipers still don't move, then it could be a relay and wiring issue, and you may need to drive the car to a mechanic.
2. Pop open the hood of your car and look at the wiper motor. It should be toward the back of the engine, just below wipers themselves. If the wipers were making nose, the motor may be a cause.
3. Close the hood of the car and look at the wiper arms. If the arms are damaged and bent, that could also be a likely cause for them not functioning.
4. Lift the wiper blades off the glass and examine how they are attached to the wiper arm. If the connecting apparatus is loose, it may cause the wipers to not work properly. One place to look would be the locking mechanism on the blade.
5. Look at the rest of the wiper assembly. If the blades themselves are damaged, you may have to replace the whole wiper blade assembly.
6. Look very closely at the wiper blade insert. If the rubber or silicone blade is worn down, frayed or broken, you may have to replace the insert itself. One option is to just replace the assembly, as wiper blade units are more widely sold than replacement inserts.
7. Consult a mechanic if these steps do not provide an answer to why the BMW's wipers are not working.

How to Become a Test Car Driver

1. Get a valid driver's license and at least a high school diploma. Take and pass a driver's education program and become knowledgeable about car safety and the rules of the road. Although a college degree is not required to become a test car driver, you should have a strong grasp of the English language and have above-average mathematical and technical ability.
2. Enroll in a car mechanic's course at your local college. Start tinkering with your own car and explore all there is to know about the engine, the interior and chassis components and how they work. Get a job as an apprentice with a reputable auto mechanic and work alongside her to get your hands dirty. While you're at it, take a course in go-karting to improve your driving skills and techniques.
3. Earn an associate's degree in mechanical or automotive engineering. Although it's not required to become a test car driver, it can give you an edge by showing car manufacturers that you're highly qualified for the job. A degree that includes manufacturing and automotive design courses will also give you a distinct advantage.
4. Take speech or writing classes to polish up your oral and written communications skills. A test car driver must be able to communicate test data and the results of his observations about a car to company team members in a professional and technically proficient manner.
5. Look into Ford Motor Company's certification program--the Electronic Driver Certification Tracking System (EDCERTS)--which tests drivers at four different tracks, skills and speeds. You can check out certification and job opportunities at Ford by accessing its website at ford.com.
6. Contact major auto manufacturers individually to find out if they're hiring test drivers or to see if you can get your foot in the door in a lower-level job first. Check out employment opportunities at BMW, Chrysler, Ford, General Motors, and Toyota and complete their online applications.
