Volkswagen engines burning oil is caused by issues with internal engine components, which is a relatively serious problem. Valve Stem Seals: The valves are essentially designed to prevent oil from leaking into the combustion chamber. However, over time, they can become worn or aged. Severe cases can affect the valve's sealing performance, making oil burning very likely to occur. Excessive Piston Clearance: When a car has been in use for an extended period, incomplete combustion can lead to carbon deposits adhering to the piston rings. If not cleaned for a long time, this can cause the gap between the piston rings and the cylinder wall to widen, allowing oil to flow into the combustion chamber and resulting in oil burning. In severe cases, it can even lead to engine seizure.

What Causes Jerking Sensation When Braking in an Automatic Transmission?

Here are the detailed reasons: 1. When experiencing jerking while driving, the first step is to determine whether it is caused by an engine malfunction or transmission gear shifting. 2. Jerking caused by an engine malfunction typically occurs when the vehicle is driven at low speeds with steady throttle input, resulting in a surging sensation. Common fault points may include the throttle body, spark plugs, or the vehicle's ignition system. 3. Jerking caused by an automatic transmission malfunction usually manifests as a noticeable impact during gear shifts. While mild jerking during gear changes is normal, severe jerking is abnormal. Common fault points may involve the transmission's shift solenoid valve or control module.

Which wire is the ground wire for the new Polo's taillight?

New Polo taillight ground wire is: The ground wire for the new Polo's taillight is the black wire. Open the taillight circuit board, and the wire that connects to all the bulbs is the ground wire. The ground wire in a car is the negative terminal of the battery connected to the car body, so the entire car is electrified. Electrical devices are installed on the car body, with one end connected to the positive terminal, and the negative terminal is conducted through the car body. The ground wire (negative) is the part connected to the car body. Here is more information: 1. The ground wire in a car refers to a current return line. The power comes out from the positive terminal of the battery, passes through various switches and electrical actuators, and then returns to the negative terminal of the battery through a return wire, forming a cycle that enables the electrical devices to perform various actions and functions. Cars use a single-wire system, meaning most wires carry their own power. 2. The return wires of various electrical actuators do not go directly to the negative terminal of the battery but indirectly return to the negative terminal through the car's own metal body. Any wire connected to the car's metal body can be collectively referred to as a ground wire.

What to Do If a Small Piece of Paint on the Car Door Chips Off?

Solutions for a small chipped paint on the car door: If the area is very small, you can use a touch-up pen to handle it yourself, which can be purchased at large supermarkets. If the area is relatively large, you need to go to a 4S shop for professional technicians to repair the paint. The car paint consists of four layers, from the inside to the outside: the electrophoretic layer, the intermediate coat, the color coat, and the clear coat. 1. Electrophoretic layer: After the body is assembled, the entire body is immersed in an electrophoretic pool, forming an electrophoretic layer on the surface of the body. The function of the electrophoretic layer is to prevent rust. 2. Intermediate coat: After the electrophoretic layer is formed on the body surface, robots will spray an intermediate coat on the body surface. The function of this layer of paint is also to prevent rust and improve the bonding ability with the next layer of paint. 3. Color coat: This layer of paint is the various body colors you usually see, and it serves an aesthetic purpose. 4.
