Fix It

The E320 is a four-door sedan made by Mercedes Benz. If you cant get your E320 to start, there are several things that you can do to troubleshoot the problem. Your issue could be occurring due to low fuel level, a bad alternator, or a low charge on your battery. Your E320 might have a dead battery, which would need to be replaced. You dont have to be a certified mechanic to get your E320 up and running. You can do it yourself with little knowledge of the subject.

Instructions

1

Insert your key into the E320s ignition and turn it. Listen for a "clicking" noise. If you hear the clicking noise, you will need to have the car towed to a garage to have the alternator replaced.

2

Look at the fuel gauge while the key is in the ignition. Add gas to the car if needed and then try to start the E320.

3

Open the E320s trunk and locate the battery. Make sure that the battery terminals are connected to the battery properly. You can tell this by the "+" and "-" signs on the terminals and the connecting wires.

4

Connect jumper wires to the "+" and "-" terminals on your battery and then connect the other end of the jumper wires to a different car battery. Start the other car with the wires connected and then try to start your car.

5

Leave the E320 running for about 15 minutes to allow the battery to charge. Turn the E320 off and wait for a couple of minutes. Start the E320 again. If the car will not start, you need to replace the battery.

The Mercedes-Benz C class was once known for its reliability, but since the merger with Chrysler in the 90s, Mercedes as a whole has lost much of its engineering reputation. To that end, many of the 2001 C-class cars have endemic electrical and mechanical faults; the SRS fault being one of the leading issues. SRS stands for the supplemental restraint system and is supposed to pre-tighten the seat belts in the event of a crash, but in practice serves only to require periodic trips to the dealership to fix its faulty sensors.There is, however, a way around this.

Instructions

1

Buy a Mercedes-Benz code reader from a website, there are many available. Make sure the code reader has a 16-pin OBDII standard socket port. The 16-pin port is what the diagnostic port on the C320 uses. 32-pin readers can be used, but an adapter and rather complex software is needed. It is simpler and cheaper to just get a 16-pin reader. No batteries are needed, as the code reader draws power from the car itself.

2

Start the car and wait for the reader to flash the name of the code reader, then press the "Read" button. It will be the green button to the bottom left. It will flash the error code three times; after the third time, press the erase button. Depending upon the model of code reader, you may have to press "Erase" after every code or only once for all the codes.

3

Disconnect the code reader and turn off the car. Then turn the car back on and replug the reader to check to see if the erasure took. If it has, you are done; if it has not, you will need to replace the SRS sensors themselves, which only a Mercedes-Benz mechanic can do.

Owning a Mercedes-Benz automobile has its advantages. Mercedes-Benz enjoys a reputation for automotive quality, safety and longevity. But repairing them requires certain specialized tools. Mechanic shops specialize in repair and maintenance of Mercedes-Benz automobiles, but you can find and purchase the specialized tools yourself. Tools for Mercedes-Benz automobiles are varied and divided into function. There are specialized tools for everything from automatic transmissions to wheels and tires.

Automatic Transmission Tools

There are a variety of specialized tools to work on automatic transmissions within Mercedes-Benz automobiles. They include tools as basic as the oil level dipstick for viewing the oil level height to various drive shaft groove nut socket wrenches. Clutch pack compressors help remove the snap ring. A brake band piston loader is a specialized assembly tool for brake pistons. A special axial play parallel rest tool measures axial play--the side-to-side movement--on the gear sets.

General Engine Tools

Specialized tools designed for general engine use are available for Mercedes-Benz vehicles. These include a special slide hammer adapter for removing the precombustion chambers from early- and late-model turbo diesels, and a specialized diesel pin wrench. A special "pencil" type, extra-long glow plug bore reamer removes heavy carbon deposits in glow plugs--a sometimes necessary first step to removing the plugs--for models 1996 to the current year. There is also one for models from 1983 and for nonturbo models from 1967 to 1985.

Electrical Equipment and Tools

Special Mercedes-Benz tools are designed to work on the vehicles electrical systems. These include a wire terminal and connector crimping master kit. The kit includes the basic crimper and five interchangeable magnetic crimping heads, along with a one-handed wire stripper that crimps butt, hex, coaxial, insulated, noninsulated, closed, flag and cord end Mercedes-Benz terminals of varying sizes. A special Mercedes-Benz data scanner reads and resets fault codes and reads live data for road tests. Also available is a bearing and race puller for use on battery terminals, small gears and bearings and relay pliers for easy removal of the Mercedes-Benz Bosch electrical relays, in the smallest, tightest locations.

The 1993 Mercedes Benz lets you know when you need to have your engine looked at by a mechanic by illuminating the "Check Engine" light on your control panel. The cause of this light can be diagnosed using an OBD II scanner tool that reads trouble codes, telling you exactly what is wrong with your car. After the codes have been read and the problem repaired, you will want to clear the check engine light to turn it off. This can be done at home with no special tools required and just a few minutes of your time.

Instructions

1

Put the key into the ignition and turn the car on but dont start the engine. Notice the display on the instrument panel between the tachometer and the speedometer.

2

Press the button on the lower left side of the steering wheel. The display will tell you why the light is on.

3

Look for the button next to the one you just pushed and press it. This will verify the reason for the check engine light.

4

Find the reset button on the instrument panel. This is located on the left side of the panel. Press and hold it until you see the instructions telling you to hold it for 3 seconds to reset it. Let go of the reset button.

5

Press the reset button one more time and hold it until the display indicates that the check engine light has been reset. Release the button. The check engine light should now be off.

Since the introduction of the 260D car in 1936, the Mercedes Benz company has been focused on diesel-powered automobiles and its cars are still on the cutting edge of todays diesel vehicles. To keep your Mercedes running smoothly, its advisable to own some of the specialized Mercedes diesel tools.

Engine Tools

If you need to remove the pre-combustion chambers on your diesel motor, use a slide hammer with a threaded adapter or get the special slide hammer adapter with two different threads. Other specialized wrenches and sockets include the pre-chamber retainer ring pin wrench, which removes and installs the threaded retainer ring of the pre-chamber, and a multi-spline socket to remove the pre-combustion chamber retainer ring on later injection diesel models. For the glow plugs, you can use a glow plug bore reamer, which is a pencil-type reamer that removes the carbon deposit from the glow plug holes. This reamer comes for turbo or non-turbo diesels. Many other tools, like hex head sockets, used to access the head bolts, can be used for both diesel and gasoline Mercedes Benz cars.

Cylinder Head and Engine Timing Tools

If you need to adjust the valves of your diesel engine, a pair of diesel valve adjusting wrenches and retaining nut holders come in handy. The diesel spring plate holding wrench will hold the retaining nut as you adjust the valves. To check the compression, get a compression gauge and an adapter. The gauge comes with a hose and the adapter of your choice. Make your car run its best with some new glow plugs, or analyze your old plugs with the glow plug analyzer, which tests 12-volt glow plug systems in the newer model diesel engines. To reach the deep port injectors and the glow plugs easily, a diesel compression adapter extension can be used.

Injection Tools

Test your cars opening pressure, the spray pattern and the cleaning injectors with a diesel injection nozzle tester. You can get this tool in a kit, which includes a gauge and the pump and steel adaptor lines. This kit is adaptable for gasoline injectors, too. A specialized diesel fuel pressure tester lets you measure the fuel pressure in high pressure CDI-type engines and a timing tool allows you to calculate the start of the fuel delivery with the RIV method. To maintain your timing while working on the pump, use a diesel pump lock pin, which locks the pump cam. The diesel drip tube helps you adjust the start of the fuel delivery and a vacuum control adjusting roller can measure the vacuum pressures on the control valve. A diesel nozzle socket and an injection socket are helpful tools, too.

The Mercedes C230 is a four-door sedan that requires gasoline and a good battery to start properly. The most common issue with a car not starting is either with the battery being dead or on a low charge, or the car doesnt have enough fuel to start. You dont have to be a certified Mercedes mechanic to get your C230 running again. You can troubleshoot the issues by checking the battery and the fuel levels yourself.

Instructions

1

Add 1 gallon of gas to your C230 and then turn the key in the ignition on and off a couple of times while you are pumping the C230s gas pedal. This will engage the cars fuel pump.

2

Turn the ignition and listen for a clicking noise. Have a mechanic check the starter if you hear a clicking noise

3

Turn the ignition over without starting the car. Check the electrical lights in your cars dashboard. If the lights do not come on or the lights are really dim, the battery needs to be charged or replaced.

4

Jump start the C230 with another car and a pair of jumper cables. Allow the car to run for about 5 minutes and then turn it off. Try to restart the car. If the car will not turn back on, you need to replace the battery.

Its simple to remove the OVP on a 190E Mercedes. The OVP, which stands for over-voltage protection, is manufactured to protect the Mercedes electrical system. The OVP is of vital importance to any owners of Mercedes because it shields against a voltage surge and protects the anti-lock braking system. You can identify the OVP by looking for its plastic cover, which sits atop the relay.

Instructions

1

Move the vehicle onto a flat work surface. Place the car in park. Shut the engine off and apply the parking brake. Open the hood of the vehicle.

2

Find the OVP relay. Its box casing is made of black plastic and is next to the car battery.

3

Take off the OVPs cover. Youll see a 10-amp fuse that leads to the relay. Remove the OVP by taking out the fuse.
