Which wheel is the problem when a Mercedes-Benz pulls to the right?

Mercedes-Benz pulling to the right is an issue with the right front wheel. Tire issues: Uneven tire pressure on both sides can cause the car to pull towards the side with lower tire pressure. If the tread depth differs between the front wheels, the car will also pull towards the side with shallower tread. Alignment data issues: Incorrect alignment data can also lead to pulling. The vehicle will pull towards the side with a larger camber angle and towards the side with a smaller caster angle. Impact of vehicle pulling: This is a serious and complex issue, mainly caused by imbalance between the left and right sides. When such a problem occurs, it is necessary to adjust the vehicle properly. Otherwise, prolonged driving in this condition will only result in uneven wear of important components like tires, leading to more safety hazards.

How to handle the P0118 fault code?

Here are the methods to handle the P0118 fault code: 1. Move or shake the related wiring harness or connectors, and observe the sensor signal on the diagnostic tool or oscilloscope. 2. If the fault appears, there will be corresponding changes on the diagnostic tool, which can help determine the location of the intermittent fault. 3. If the sensor circuit is short-circuited to the battery positive voltage, both the ECM and the sensor may be damaged. Additional information: 1. Fault code P0118 applies to all car manufacturers. Chinese meaning: Engine Coolant Temperature (ECT) Sensor 1 Circuit High. English meaning: Engine-Coolant-Temperature-Sensor-1-Circuit-High. 2. Possible causes include: the sensor signal line is short-circuited to ground; the resistance is too small; the sensor is damaged. If the engine runs for 60 seconds, the coolant temperature is below -42.75°C, and the fault duration exceeds 2 seconds, it can be concluded that the coolant temperature sensor signal voltage is too high.

What should I pay attention to when picking up the car?

When picking up the car, it is necessary to check the engine, exterior scratches, and other aspects. The following are the specific precautions for picking up and inspecting the car: 1. Observe the body: Visually inspect the paint surface of the car body to check for scratches and wear. Observe the paint under sufficient sunlight to see if there is any color difference. Open the car door and push and pull it from several angles to let light shine from different angles to check if the sheet metal is even. 2. Inspect the doors: Open the doors and pay attention to whether they open and close smoothly, and whether the gaps between the doors and the front and rear bumpers are consistent. 3. Check the engine: Open the engine hood and check if the engine compartment is clean. If the car has been stored for a long time or used, some areas may have obvious dust or stains. 4. Check the glass: Check if the windshield is original. 5. Check the vehicle nameplate: The car nameplate is located on the side of the driver's door or in the engine compartment. Pay attention to whether the manufacturing date is too far from the current date. If the time exceeds six months, the car is likely to be a stock car or a test drive car.

Can a newly purchased car without temporary license plates be driven on the road?

A newly purchased car without temporary license plates cannot be driven on the road. Before the official license plates are issued, temporary plates are the only legal document for driving. According to the "Road Traffic Safety Law," if a motor vehicle driven on the road does not display license plates, the traffic management department of the public security organ shall detain the vehicle, notify the party to provide the corresponding plates, and impose a fine of 200 yuan and deduct 12 points in accordance with Article 90. When applying for temporary license plates, the following documents must be submitted as required, along with the completed "Temporary Vehicle Registration Form": 1. Identification documents of the vehicle owner and the agent; 2. Proof of the vehicle's origin; 4. For domestically produced vehicles, the whole vehicle factory qualification certificate; for imported vehicles, the import certificate; 5. The vehicle identification number (VIN) and engine number imprint. After reviewing the above documents and ensuring they comply with regulations, and after passing the safety and technical performance inspection of the vehicle, the vehicle management office will issue temporary license plates, specifying the validity period and the start and end locations.

How to Choose the Right Engine Oil Viscosity Grade?

Choosing the right engine oil viscosity grade: Temperature and operating conditions are two key criteria for selecting engine oil. In regions with low winter temperatures, opt for a grade with a smaller number before the "W." For those who enjoy driving fast or have older vehicles, choose a grade with a higher viscosity coefficient after the "W," preferably from higher-end brands. When selecting engine oil, focus on two main aspects: the oil's performance level and its viscosity. Additional Information: 1. The performance level of engine oil can be found on the outer packaging of the oil container, with different levels suited for different engines. Generally, engines with higher RPMs or vehicles with higher cylinder pressures require higher-quality oil. Refer to the vehicle's manual; if the same performance level is unavailable, choose one grade higher than recommended, never lower. 2. For viscosity selection, consider the vehicle's usage and engine condition. In cold northern winters, choose oil with strong low-temperature fluidity. For older engines with poor cylinder wall sealing, thicker oil is recommended, as overly thin oil may lead to oil consumption issues. In southern regions with stable temperatures, 10W-20 oil is sufficient, and there's no need to opt for expensive options.

What is the appropriate pressure for car air conditioning pressure testing?

For car air conditioning pressure testing, a pressure of around 20-30 bar is suitable, which should be higher than the working pressure of the car air conditioning system. Nitrogen is generally used for pressurization and leak detection in car air conditioning systems. More details are as follows: 1. During the pressurization and leak detection of the car air conditioning system, use soapy water to check for leaks at the pipe connections. Whether pressurizing from the high-pressure or low-pressure side, the pressure will eventually balance within the system. Nitrogen is typically introduced from the high-pressure side, but Freon can also be added to the system for leak detection using a halogen leak detector, though this method is less effective than soapy water. Since Freon operates at lower pressures within the system, minor leaks may be harder to detect. 2. Once the refrigeration system's vacuum meets requirements and no leaks are found, refrigerant can be added. Before charging, determine the correct amount of refrigerant, as too much or too little will affect cooling performance. The compressor's nameplate usually specifies the type and required amount of refrigerant. 3. When using the car air conditioning, proper maintenance is essential. Avoid randomly adjusting the air vents, as improper direction can reduce efficiency. Based on the principle that cold air sinks and warm air rises, set the vents upward when cooling and downward when heating for optimal performance.
