Different vehicle models may interpret the C1201 fault code differently. However, whenever this fault code appears, it indicates an engine malfunction, and it is essential to visit a 4S dealership for professional diagnosis. The specific cause must be analyzed based on the actual situation. Additional explanation of automotive fault codes: 1. An automotive fault code is a code generated by the vehicle's computer ECU after analyzing a malfunction. This means the vehicle currently has a problem, and the malfunction indicator light remains illuminated. To fully resolve the issue, a professional decoder (such as K81 or a laptop) is required to decode the fault, which is commonly referred to as troubleshooting. 2. Fault codes are categorized into genuine codes, historical codes, and intermittent codes, with genuine codes being easier to detect.

Why is the rear seat light always on?

If the rear seat light is always on, first check whether the switch has been triggered, and then consider the possibility of a wiring fault. The car light has three modes: 1. ON: Constant-on mode. When this switch is turned on, the ceiling light will stay on continuously and will not turn off even after the car is locked. 2. DOOR: In this mode, the light only turns on when the door is opened. 3. OFF: When this mode is selected, the ceiling light remains off and will not illuminate. Below is an extended introduction about car headlights: 1. Function: Car headlights are used for illumination during nighttime driving. Also known as car front lights or LED daytime running lights, they serve as the "eyes" of the car, not only affecting the owner's external image but also closely related to safe driving at night or in bad weather conditions. 2. Types: (1) By purpose: Car lights can be divided into two categories: illumination and auxiliary. Among them, only the headlights and some fog lights equipped on certain cars serve an illumination purpose, while the rest are auxiliary lights. (2) By category: Currently, there are four types of car headlights: laser headlights, LED car headlights, xenon headlights, and halogen lights.

What is the H-series of the Tiggo 8 headlights?

The Tiggo 8 headlights are H7. The maintenance methods for the headlights are: 1. Check the sealing of the headlights. If there is moisture inside the headlights, it will reduce the lifespan of the bulbs. If the sealing ring between the lens and the reflector is damaged, replace it promptly. 2. Clean the bulbs. Use alcohol-soaked degreasing cotton to wipe off dust and dirt on the bulbs. After cleaning, let them dry and avoid touching the bulbs with hands or cloth. 3. Clean the reflector. Use clean cotton dipped in hot water to clean the reflector, but do not wipe it to avoid damaging the reflector coating. Taking the 2020 Urban Edition Tiggo 8 as an example, its front suspension is a MacPherson independent suspension, and the rear suspension is a multi-link independent suspension. It is equipped with a 1.5L turbocharged engine, with a maximum horsepower of 156 PS, a maximum power of 115 kW, and a maximum torque of 230 Nm. It is paired with a 6-speed manual transmission.

What is the difference between Audi A4 35 and 40?

Audi A4 35 and 40 represent differences in gravitational acceleration ratio. Numbers are used to replace displacement, with larger values indicating better acceleration from 0 to 100 km/h. The main difference between A4 30TFSI and 40TFSI models lies in their completely different engines and transmissions. More details are as follows: 1. Increased power: For the current A4 models, the new versions no longer have 35TFSI, starting from 40TFSI as the minimum. Even with the same 2.0 displacement, the new 40TFSI has greater engine power and torque compared to the old 35TFSI, meaning improved overall power. 2. 35TFSI meaning: This indicates the vehicle's acceleration is approximately 0.35 times the free-fall acceleration (gravitational acceleration g). Free-fall acceleration to 100km/h takes about 2.83 seconds, so this vehicle requires roughly 8.1 seconds to reach 100km/h (35TFSI, 40TFSI, 45TFSI, 50TFSI etc. use 5 as quantization unit, with certain quantization errors).

What kind of lubricating oil is used for the brake caliper guide pins?

Ecco-Grease-EM71-2 special grease for plastic and rubber. Below are the relevant details: 1. Introduction to brake caliper and guide pin lubricant: Ecco-Grease-EM71-2 special grease for plastic and rubber is a lubricating grease made from polyether synthetic oil as the base oil, special lithium soap as the thickener, and refined with various additives such as antioxidants, anti-corrosion agents, and anti-aging agents. This plastic and rubber compatible grease is designed for the assembly lubrication of rubber, plastic, and metal components that are sensitive to most greases, such as ethylene propylene diene monomer rubber, styrene-butadiene rubber, and natural rubber. It features excellent adhesion, wear resistance, and corrosion resistance. 2. Brake caliper: An essential component of the chassis braking system, its main function is to push the brake pads, which then rub against the brake drum to reduce speed and bring the vehicle to a stop. When the brake pedal is pressed, the master cylinder generates thrust to push hydraulic oil to the caliper, and the piston inside the caliper moves under hydraulic pressure to push the brake pads.

What is the method for escaping from a submerged vehicle?

When a vehicle is submerged in water, the method for escaping is to unfasten the seatbelt and open the car door immediately, as exiting through the side door is the safest and quickest way. After the car enters the water, it will not sink to the bottom instantly. At this moment, you should quickly unlock the electronic central locking system to prevent the door locks from failing. These few seconds can make a life-or-death difference. Below are some driving precautions: 1. Check the rearview mirrors: When turning or changing lanes, you must use the turn signals, slow down, and always check the rearview mirrors before turning. For left turns, primarily check the left rearview mirror; for right turns, primarily check the right rearview mirror. For both left and right turns, you must also check the interior rearview mirror. 2. Do not focus solely on the area directly in front of the car: When driving on a clear road, look straight ahead at a distance of about 100 meters, avoiding fixation on the immediate area in front of the car. 3. Depress the clutch: Generally, when decelerating at speeds above 40 km/h, there is no need to depress the clutch immediately. Wait until the speed drops to around 20 km/h before depressing the clutch. 4. Steering: When making high-speed turns, steer slowly; when making low-speed turns, steer quickly.
