What does the yellow P light mean?

The yellow P on the car dashboard indicates that the parking brake is engaged, meaning the handbrake is in the braking position. Below are the specific reasons why the P light remains illuminated in yellow: 1. Handbrake not fully released: Some drivers forget to release the handbrake or do not release it completely, causing the handbrake light to turn on. 2. Brake fluid leakage: It is necessary to check the brake fluid, as leakage or insufficient brake fluid may cause the handbrake light to illuminate. The braking system mainly consists of energy supply devices, control devices, transmission devices, and brakes. The primary function of the braking system is to slow down or stop a moving car, maintain a stable speed for a car going downhill, and keep a parked car stationary. Using a fault detection device for inspection can quickly and accurately locate the fault and identify the cause step by step. 3. Worn brake discs: Accompanied by body vibration or abnormal noises when braking, it is likely due to thinning brake discs or foreign objects entering the brake pads. Uneven surfaces on the brake discs can cause sharp metal friction sounds when braking, as well as insufficient braking force, longer braking distances, and softer braking.

Reasons for Car Shaking and Abnormal Noises

Car shaking and abnormal noises are caused by friction between the car door and the frame, or shaking, or friction between steel plates due to welding failure. Additionally, loose fastening between car body components can also lead to abnormal noises. Below is a detailed introduction to car shaking and abnormal noises: 1. The cause of abnormal noises in the car engine should be determined based on the sound: a. A sharp belt squealing noise is caused by belt slippage; b. A sharp metal-on-metal friction sound during engine operation indicates damage to the generator, water pump, or power steering pump bearings; c. A hissing sound during engine operation may be due to a blocked exhaust system, vacuum tube leakage, or breakage. 2. Tire noises: When car tires come into contact with the ground, various noises of different intensities are produced depending on the type of road, surface irregularities, car speed, tire type, and tire air pressure. If the tire noise is rhythmic and increases in frequency with speed, the cause can be determined by the sound. A dull "thud" sound often indicates tire tread deformation, bulging, severe wear, or insufficient air pressure. A "clicking" sound may be caused by small stones stuck in the tread. 3. Suspension noises: Suspension components are not only related to ride comfort but also to driving safety. When passing over speed bumps or uneven roads, suspension noises can be very severe. A "thumping" or "clunking" noise on flat roads is usually caused by shock absorber issues or loose suspension components. 4. Engine guard noises: Screws on frequently moving parts of the car often shift. If you frequently hear a "rattling" noise near the grille area, aside from the grille being loose, the owner should also check if the engine guard screws are loose or if the engine guard is loose against the underbody. Besides tightening the screws, placing cardboard-like materials in the noisy area can help eliminate the noise.

What engine does the Volkswagen Passat have?

The Passat engine is produced by FAW-Volkswagen Engine (Dalian) Co., Ltd., manufactured at the Dalian Powertrain Plant. The Passat 2.0T engine model is EA888, with a maximum power of 162kW and maximum torque of 350Nm. The 1.4T engine model is EA211, with a maximum power of 137kW and maximum torque of 320Nm. For daily maintenance of the Passat engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements; Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, causing various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, bypassing through the relief valve and carrying contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures normal engine operation but also extends the overall lifespan of the radiator and engine.

Can 4S shops do free four-wheel alignment?

4S shops do not offer free four-wheel alignment. Generally speaking, the charges for repair and maintenance services at 4S shops are higher than those outside, and the same goes for four-wheel alignment. Not only is four-wheel alignment not free at 4S shops, but the price is also higher than at some repair shops outside. The following are situations where four-wheel alignment is needed: 1. Tire pressure and tire tread wear: Uneven tire wear indicates a problem with the tires, steering system, or suspension, among other things. There are many reasons for irregular tire wear and excessive wear. The most common reasons include improper inflation pressure, failure to rotate tires regularly, improper driving habits, or incorrect original four-wheel alignment. 2. Wheel wobble: Wobble is a condition where the tire rotates unstably due to various reasons. The wobble of the wheel and tire refers to irregular up-and-down or left-and-right movements. Left-and-right movement refers to the lateral wobble of the wheel or tire, while up-and-down movement refers to the radial wobble of the wheel or tire. Vibration issues related to wobble can only be resolved by identifying the source of the wobble. 3. Wheel deviation: Deviation refers to the situation where the vehicle drifts from its intended direction while driving straight on a road, with the steering wheel not subjected to any external force.

Does BAIC Senova Use Aisin Transmission?

BAIC Senova uses Aisin transmission. Founded in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest global market share. The BAIC Senova transmission employs a single-speed fixed gear ratio transmission. A transmission that changes vehicle speed through different gear ratios is called a fixed gear ratio transmission, which is also a type of electric vehicle transmission. With this design, power is directly transmitted from the motor to the transmission, which then delivers the power directly to the two wheels, reducing power loss. It also offers advantages such as simple structure, ease of manufacturing, and low production costs. When using the BAIC Senova transmission in daily driving, pay attention to the following points: Do not delay changing the transmission oil for extended periods. Prolonged failure to change the transmission oil can lead to damage to internal components such as bearings and the housing. Avoid prolonged coasting in neutral. While driving manual transmission vehicles, many experienced drivers may coast in neutral, but for automatic transmission vehicles, this can cause the transmission to overheat and may result in a noticeable jolt when shifting back into Drive (D) mode. Never shift into Drive (D) or Reverse (R) before the vehicle has come to a complete stop. Some drivers, aiming for smooth operation, may shift into reverse while the vehicle is still moving, which can cause significant damage to the transmission gears and, over time, lead to gear grinding and other failures. Avoid frequently climbing steep slopes in Drive (D) mode. When facing steep inclines, automatic transmission vehicles may overheat due to high load or shift prematurely, resulting in insufficient climbing power. In such cases, use manual mode to limit the gear to a lower speed or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, use a flatbed tow truck to move the vehicle onto the tow platform while it is in Neutral (N) mode. Do not use a tow rope or similar method to directly tow the vehicle.
