The reasons for the P light being on: 1. ABS function failure; 2. Severe brake pad wear leading to failure; 3. Brake oil not meeting requirements. Abnormalities in the braking system manifest as poor or failed braking, unilateral braking deviation, braking noise, brake drum overheating due to brake drag, parking brake failure, etc. The braking system mainly consists of four parts: the energy supply device, control device, transmission device, and brake. Its main functions are: 1. To decelerate or even stop a moving vehicle; 2. To maintain a stable speed for a vehicle going downhill; 3. To keep a parked vehicle stationary.

How to Apply a Roof Wrap?

Here are the steps to apply a roof wrap: 1. Clean the car body: First, clean the car body and ensure it is dry. Remove the decorative strips on the roof. 2. Positioning: Determine the exact position where the wrap will be applied. Generally, apply it slowly while using a tool to smooth it out and peel off the backing paper simultaneously. 3. Applying the wrap: If the design is relatively small, you can peel off both the transparent transfer film and the wrap entirely before applying. However, be careful to avoid accidental adhesion. 4. Smoothing: After application, repeatedly smooth it out several times. Remove the transparent transfer film. Use a utility knife to make a cut at the door and seam areas, then fold it inward for a snug fit. Ensure there are no separations or bulges between the wrap and the car body.

Does a BMW need maintenance after running 20,000 kilometers?

After running 20,000 kilometers, a BMW requires appropriate maintenance. Below is relevant information about vehicle maintenance. 1. Types of maintenance: cleaning the throttle body and fuel injectors, four-wheel rotation and balancing, replacing the cabin air filter, and cleaning the catalytic converter. 2. Cleaning the throttle body and fuel injectors: This depends on the vehicle's usage. Vehicles that frequently drive on highways are less likely to be dirty and may not need cleaning. If the vehicle often drives in congested areas or for short distances, it is more likely to accumulate dirt and should be cleaned. 3. Cleaning the catalytic converter: The catalytic converter generally does not need cleaning unless there is a fault code or the vehicle fails an emissions test. 4. Four-wheel rotation and balancing and replacing the cabin air filter: It is recommended to perform both. Four-wheel rotation helps ensure even tire wear and extends tire life, while the cabin air filter, like the engine air filter, tends to get dirty quickly and should be replaced more frequently.

How to Deal with a Tire Blowout While Driving at High Speed?

Hold the steering wheel firmly with both hands and repeatedly apply the brakes in a pumping motion. Below is relevant information about tire blowouts on highways: 1. Causes: Underinflation - as tire pressure decreases, friction between the tire and road surface multiplies, leading to increased tire temperature, softening of the tire, and reduced strength. 2. Maintenance recommendations: Always prioritize tire protection by regularly checking tire pressure and maintaining standard levels. If a tire gets punctured by a nail or has a slow leak, prompt repair is advised. Before highway driving, conduct a thorough vehicle inspection. Additionally, severely damaged tires, even after repair, should preferably not be used for long-distance or high-speed driving as a precautionary measure.
