What Causes Uneven Steering Wheel Resistance?

Where are the positions of BMW's front oxygen sensors 1 and 2?

The first sensor always refers to the upstream oxygen sensor (before the catalytic converter), and the second sensor always refers to the downstream oxygen sensor (after the catalytic converter). A four-cylinder engine generally has only one bank, so the first sensor in bank 1 refers to the upstream sensor, and the second sensor in bank 1 refers to the downstream sensor. For six-cylinder or eight-cylinder engines: in the case of rear-wheel drive (with the pulley at the front of the car), the passenger side is bank 1, and the driver side is bank 2. The effects of a damaged oxygen sensor are as follows: Abnormal vehicle signals: An oxygen sensor malfunction usually triggers a warning light, causing abnormal signal output. The engine may shake, produce a sputtering exhaust sound, emit a pungent odor, and even disrupt the air-fuel ratio, leading to black smoke emission. If the front oxygen sensor is damaged, it must be replaced immediately and should no longer be used. Abnormal vehicle operation: If the oxygen sensor or its connecting circuit fails, it not only increases emissions beyond the standard but also worsens the engine's operating conditions. This can lead to symptoms such as stalling at idle, inaccurate engine operation, reduced power, and an imbalanced engine air-fuel mixture, resulting in increased fuel consumption.

What to Do When the Tiguan's Fan Keeps Running?

Tiguan fan continuous operation solutions are as follows: 1. Insufficient coolant causing engine overheating, leading to continuous operation of the electric fan. The solution is to add antifreeze. 2. Radiator leakage causing engine overheating, leading to continuous operation of the electric fan. The solution is to replace or repair the radiator. 3. Thermostat failure, preventing water from being sent to the radiator even when the temperature reaches the baseline, causing engine overheating and continuous operation of the electric fan. The solution is to replace the thermostat. Methods to determine the condition of the electric fan are as follows: 1. Visual Inspection: Observe the fan motor's ventilation port for any signs of burnt coils. If there are burnt marks, it indicates the fan motor coils are burnt and cannot be used. 2. Smell Test: Use your nose to detect any burnt smell from the fan motor, such as burnt coil smell, burnt plastic smell (capacitor), or burnt wire smell (wiring). If any burnt smell is detected, replace the fan motor, wiring, and capacitor. 3. Touch Test: Manually check the fan's operation by turning the shaft. If it feels stiff or not smooth, it indicates lack of lubrication in the internal bearings or rotor scraping. If scraping is found, lubricate and clean, and replace the bearings on both sides to eliminate the scraping. Check the surface temperature; if it rises too quickly or too high, it indicates a short circuit in the fan motor, and the fan motor needs to be replaced.

What type of engine oil is used for the BMW X6?

The standard oil for the BMW X6 is BMW-Quality-Longlife-04-0W-40-Oil-D. The gray shell is 5W-40, which is of a slightly lower grade and should be replaced every 5,000 kilometers. Mobil 1 Full Synthetic Oil: For higher quality, Mobil 1 Full Synthetic Oil can be used. Mobil 1 oil can also be mixed with any other oil. The Mobil 1 0W-40 Gold is the most advanced synthetic engine lubricant, specifically formulated to meet the ultimate requirements for engine cleanliness, wear protection, and overall performance. Its technology, validated by racing, is also the chosen lubricant for NASCAR. BMW X6: The BMW X6 can be equipped with a 3.0-liter twin-turbo diesel engine, a 3.0-liter twin-turbo gasoline engine, a new 4.4-liter V8 gasoline direct-injection twin-turbo engine, and a 4.8-liter gasoline engine. However, the BMW X6 models introduced in China are only equipped with the 3.0-liter and 4.4-liter V8 gasoline direct-injection twin-turbo engines. Additionally, the BMW X6 is equipped with a Dynamic Performance Control system to enhance driving stability and handling precision, working in conjunction with the xDrive AWD system to optimally distribute driving force between the front and rear axles.

Does the Corolla Meet China 6 Emission Standards?

Starting from the 2019 model, the Toyota Corolla has been compliant with the China 6 emission standards. Differences in Limit Values Between China 6 and China 5 Standards: The China 6 standards impose approximately 40% to 50% stricter limit values compared to China 5. China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. In contrast, during the China 5 phase, diesel and gasoline vehicles had different emission standards. Differences Between China 6 and China 5 Emission Standards: Compared to China 5, China 6 reduces nitrogen oxides (NOx) by 77% and particulate matter (PM) by 67%. It introduces a limit requirement for particle number (PN) and imposes stricter regulations on emission control device durability and onboard diagnostic (OBD) system requirements. Purpose of Establishing China 6 Emission Standards: The China 6 emission standards specify the requirements for the sixth-stage type inspection of light-duty vehicle pollutant emissions, as well as the methods for checking and determining production conformity and in-use compliance. Manufacturers are obligated to ensure that the vehicles they produce and sell meet the in-use compliance requirements stipulated by the China 6 emission standards.

Is it allowed to touch the line when reversing into the garage?

Touching the line with the car body means the car body crosses the line, which results in a deduction of 100 points, making the test unsuccessful. Crossing the line with the car body, failing to enter the garage, stopping midway, not following the prescribed route or sequence, or exceeding the time limit will also result in a deduction of 100 points. The full score for both subjects is 100 points, with evaluation criteria set for failure, deduction of 20 points, deduction of 10 points, and deduction of 5 points. The rules for the Subject 2 test of the motor vehicle driver's license application state that stopping or rolling back midway during the test, or not following the voice prompts, will result in failure. If the wheels or car body touch the line, the test will be considered unsuccessful. Many learners encounter the issue of touching the line during Subject 2 training, and "touching the line" is the most common mistake leading to failure. The main reason for touching the line is that learners fail to grasp the correct timing for steering. Besides missing the right moment to steer, another reason could be that the steering speed does not match the car's speed. Subject 2 Deduction Standards: Not wearing a seatbelt: Deduct 100 points. Starting the engine without the gear in neutral: Deduct 100 points. Not using the turn signal (including starting, changing lanes, overtaking, turning, or parking); using the turn signal for less than three seconds (note that this is easily overlooked!); forgetting to turn off the turn signal or using it incorrectly: Deduct 10 points. Stalling once: Deduct 10 points. Reversing into the Garage: Not following the prescribed route or sequence: Deduct 100 points. Car body crossing the line: Deduct 100 points. Failing to reverse into the garage: Deduct 100 points. Before reversing, if both front wheels do not pass the control line: Deduct 100 points. Exceeding the 210-second time limit: Deduct 100 points. Stopping for more than 2 seconds midway: Deduct 5 points each time. Slope Parking and Starting: After stopping, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: Deduct 100 points. After stopping, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: Deduct 10 points. After stopping, if the starting time exceeds 30 seconds: Deduct 100 points. Driving with wheels touching the road edge line: Deduct 100 points. Starting with the car rolling back more than 30 cm: Deduct 100 points. After stopping, if the car body is more than 50 cm away from the road edge line: Deduct 100 points. After parking, not tightening the parking brake: Deduct 10 points per occurrence. After stopping, if the car body is more than 30 cm but less than 50 cm away from the road edge line: Deduct 10 points per occurrence. Starting with the car rolling back more than 10 cm but less than 30 cm: Deduct 5 points per occurrence. Parallel Parking: After parking, if the car body crosses the line: Deduct 100 points. Not using or incorrectly using the turn signal when entering the garage: Deduct 10 points. Exceeding the 90-second time limit: Deduct 100 points. Driving with the car body touching the garage edge line: Deduct 10 points per occurrence. Driving with wheels touching the lane edge line: Deduct 10 points per occurrence. Stopping for more than 2 seconds midway: Deduct 5 points per occurrence. 90-Degree Turn: Wheels touching the road edge line: Deduct 100 points. Not using or incorrectly using the turn signal during the turn, or not turning it off after the turn: Deduct 10 points. Stopping for more than 2 seconds midway: Deduct 5 points per occurrence. Curve Driving: Wheels touching the road edge line: Deduct 100 points. Stopping for more than 2 seconds midway: Deduct 100 points. Driving without the gear in second or higher: Deduct 5 points.

How many ETCs can one vehicle apply for at most?

A vehicle can only apply for one ETC. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Expressways" issued by the Ministry of Transport, the application for ETC is related to the vehicle's driving license. If you own multiple vehicles, you can use different driving licenses to apply for ETCs. Documents required for ETC application: The original valid ID card of the vehicle owner, the original and a copy of the vehicle's driving license (the page with the most recent annual inspection stamp should be provided). If applying on behalf of someone else, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a debit or credit card from the corresponding bank is needed. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding with debit cards. The current year's vehicle insurance policy is also required. For corporate applications, the agent's ID card (or driver's license), the organization's code certificate (or business license), and the official seal are needed. ETC deduction principle: There will be one or more ETC lanes on the expressway. Through the dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for background settlement with the bank, the purpose of paying tolls without stopping at the toll station is achieved. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and environmentally friendly: Low-carbon, vehicles pass the toll station without stopping, reducing noise and exhaust emissions, and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, lowering wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased," and explicitly proposed in the main indicators of the "13th Five-Year" comprehensive transportation development that "by 2020, the ETC usage rate of road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the usage rate of ETC passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front stopping, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, leading to deduction failure. Unauthorized disassembly or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was applied for or the expressway service office for testing. Non-human loosening or detachment only requires reactivation. When using a debit card bound to ETC, insufficient balance will also cause deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Poor sensing due to overly thick car windshields. Especially for vehicles that have had accidents and replaced windshields, or those who have modified front windshields, need to pay attention.
