Mercedes Benz C200L stops to keep the engine running, and how to solve the failure of the auxiliary

Possible Causes of Failure:

1. The fuse of the auxiliary battery is damaged;

2. The auxiliary battery is damaged;

3. Generator or charging system failure;

4. Related wiring harness failure, etc.

If the capacitor (C8) fails, the instrument panel displays "Auxiliary Battery Fault". Check the circuit of the parking brake jaw capacitor (C8), and no abnormality is found; The generator and charging system were inspected and no abnormalities were found.

Since the power supply, circuit, and charging system of the parking brake jaw capacitor (C8) are normal, it is inferred that the parking brake jaw capacitor (C8) is damaged.

If the Mercedes-Benz C200L stops to keep the engine running and the auxiliary battery fails, then the auxiliary battery must be replaced.

This situation is affected by the battery being dead, and the engine should be kept running after such a situation, so that the battery can be charged.

Mercedes Benz stops to keep the engine running, which means to stop the car and let the engine idle. There are two situations where you need to stop and keep the engine running.

One is that the engine temperature is too high, and you need to stop the car to keep the engine running, because in this way, the coolant can be continuously circulated to dissipate heat.

The second is that the battery is insufficient, and it needs to idle for a period of time to charge the mountain hollow. Mercedes-Benz is a German automobile brand known for its luxury and high performance, headquartered in Stuttgart, Germany, is a member of Daimler AG, its products include all kinds of passenger cars, medium and large commercial vehicles, etc.

The above battery alarm information appears.

Here's why:

1. The use of vehicles is often short-distance driving, or often turning off the engine to listen to songs and listen to the radio, such as driving 2 times a day, each trip is not more than 5 kilometers, the distance is too short to fully charge the battery, so the battery power has been consumed, and the supply is not enough.

2. Energy system failure, specifically:

a. Battery sensor failure.

b. Generator and its wiring problems.

c. SAM control unit failure.

d. The aging and storage capacity of the battery is not good and needs to be replaced.

e. The vehicle sleep current is too large or cannot enter the sleep state.

f. Terminals and lines between batteries, battery sensors, and SAM control units.

Summary: The above information needs to be charged (or run long distances) for shorter vehicles (less than 2 years), and the above prompts for older vehicles need to be replaced.

Mercedes-Benz C200 shows a battery sign to stop to keep the engine running, this is the vehicle's excessive power consumption indicator, that is, the electrical appliances in the car consume too much, resulting in the battery starvation of the world, at this time it will prompt the driver to stop in place and transport the ** motor to charge the battery, in this situation, you can turn off part of the electrical appliances in the car, and then restart the vehicle will eliminate the prompt, the specific operation steps are as follows:

1. Open the driver's door of the Mercedes-Benz C200.

2. Place the smart key of Mercedes-Benz C200 in the front of the induction slot, that is, the storage slot.

3. Step on the brake pedal of the Mercedes-Benz C200.

4. Press the one-button start button of Mercedes-Benz C200.

5. The instrument of Mercedes-Benz C200 lights up and the vehicle starts.

Summary. Hello dear, Mercedes stops to keep the engine running, which means that the battery cannot be charged. In this case, you should stop immediately, pay attention to the road and traffic conditions, shift the gear to P parking and keep the engine in working condition, at this time the engine speed is often a little high, which is normal.

However, after more than 30 minutes, it still prompts "stop to keep the engine running", which is most likely caused by the battery being unable to charge normally.

Hello dear, envy Liang La Mercedes-Benz stops to keep the engine running, which means that the battery cannot be charged. In this case, you should stop immediately, pay attention to the road and traffic conditions, shift the gear to the P parking brother slip gear and keep the engine in working condition, at this time the engine speed is often a little high, which is normal. However, more than 30 minutes still prompt "stop to keep the engine running", this slag number is most likely caused by the battery has not been able to charge normally.

Mercedes-Benz cars appear "stop to keep the engine running" prompt will be accompanied by a warning sound, there are three possible causes of this kind of problem in car skating: 1. Generator failure, generator brush is a vulnerable substance. However, generator failures can only be replaced and not repaired, which is an unspoken rule of the industry.

2. The fault point of the electronic system is often the short circuit, open circuit or loose tie in the electrical circuit. The repair cost of electronic faults is relatively low, and finding the fault point can solve the problem. 3. The generator belt is torn, and in this case, do not continue to drive, otherwise the brigade orange engine is easy to overheat.

The solution is to replace the generator belt with a new one.

**The C-class chassis model of the 205 and C200 does not have a battery attached to it, and only the mild hybrid model has a battery that is located in the front right of the vehicle, in the engine compartment. The additional battery of the ECO start-stop function of the C200 of the previous generation Ben chassis model 204 is next to the spare wheel of the trunk.

Mercedes-Benz new C200 auxiliary battery is under the floor of the trunk of the car, which is used to supply power to the body electrical appliances, not to the starter of the vehicle

1. Open the door on the cab side of the new Mercedes-Benz C200.

2. Pull up the Mercedes-Benz new C200 handbrake to prevent rolling.

3. Pull the trunk switch on the left side of the driver's leg of the new Mercedes-Benz C200.

Fourth, lift the trunk of the new Mercedes-Benz C200 up, and the trunk will be opened.

Fifth, you can find it by lifting the floor.

The engine compartment of the Mercedes-Benz C200 can be unlocked by first pulling the engine lock wrench on the lower left side of the vehicle's cockpit.

The bonnet can then be opened by pulling the wrench on the bonnet. The engine compartment cover can then be propped up using a hydraulic rod. When propped up, you can see the engine compartment layout.

The batteries commonly used in cars are lead-acid battery pools. Maintenance-free batteries are generally equipped with a fuel indicator (also known as a charge indicator) that can indicate the level of charge or charge of the battery. The indicator shows green, black, colorless, or light yellow, among others.

When the ambient temperature rises by 1°C, the capacity of the battery will also increase accordingly; Conversely, when the ambient temperature decreases by 1°C, the capacity of the battery will also decrease.

When the temperature is as low as -10°C, the capacity of the battery is only 72% of the normal value; When the temperature is as low as -20°C, the capacity of the battery is only 64% of the normal value; In addition, car batteries are lead-acid batteries with shallow charge and shallow discharge, and excessive discharge is a great harm to the battery. The vehicle's battery can then be found in the engine compartment diagram.

Some are in the engine compartment, called starter batteries (produced in 05-09). Some are under the meter and are called auxiliary batteries. Some are in the trunk and are called auxiliary batteries (ECO batteries).

The original Mercedes-Benz C200L battery adopts the Varta brand. There are differences in the battery of different versions of models, and whether there is an automatic start-stop function will also affect the battery model, and the owner must consult clearly before purchasing.

Mercedes-Benz C200L battery replacement tutorial

Location: Top left corner of the engine compartment.

1. The battery is in the engine compartment, so open the engine compartment and find the battery first.

2. Disassemble the battery end protection and fixing bracket nut.

3. Disconnect the negative connection of the battery and then disassemble the positive connection. In order to avoid the occurrence of short circuits, the negative electrode is removed first, after all, the negative electrode is connected to the body.

4. Usually there will be fixtures around the battery, and we need to remove all the fixtures before the battery can be replaced. (Note: The electrolyte on the old battery can easily flow out when the tilt angle is greater than 40°).

Note: It is best to operate without power when replacing the battery (it is not recommended for the owner to operate it yourself), otherwise it will cause the data loss of the dashboard, the owner's daily operating habits and driving data are all restored to factory settings, and information such as the date must be re-adjusted.

Mercedes-Benz series models, when replacing the battery, is not like other German cars to match, as long as the battery model, ampere-hours match, is not required to match. It should be noted that when installing the battery, the positive and negative poles should never be reversed.

What do I need to pay attention to when replacing the battery?

1. When replacing the battery, it is necessary to replace the AGM battery with the same specification as the original car, if the general battery is replaced, because the specifications are different, the engine module will judge that the power supply voltage is too low, resulting in the failure of the signal can not be eliminated. (1) If you want to replace it after power failure, you must first take the key out of the car and wait for 5 minutes to let the vehicle enter sleep mode before replacement. (2) If uninterrupted power replacement is adopted, it should be noted that the positive electrode should not be used to catch the iron to the body during the replacement process, which may cause other phenomena of module failure lamp.

3. When connecting the battery wiring, connect the positive electrode first, and then connect the negative electrode. After installation, the battery binding post can be sprayed with anti-rust protector or grease-free for protection.

When the Mercedes-Benz ammeter pointer shows that the storage capacity is insufficient, it should be charged in time. The storage capacity of the Mercedes-Benz E-Class battery can be reflected on the dashboard. Sometimes on the way to find that the power is not enough, and the engine can not be turned off and started, as a temporary measure, you can ask for help from other vehicles, use the battery on their vehicle to start the vehicle, and connect the negative and negative poles of the two batteries, and connect the positive and positive electrodes.
