Reasons why the brake light on the car dashboard stays on: 1. Worn or aged brake pads - in this case, the brake pads should be replaced. If you drive without releasing the brake, the light will also stay on; 2. Insufficient brake fluid - brake fluid plays a crucial role in the car's braking system. When the driver presses the brake pedal, the piston in the master cylinder transmits energy through the brake fluid to the wheel cylinders at each wheel, achieving the purpose of stopping the vehicle. The functions of car brake lights are: 1. The rear brake lights and high-mounted brake lights are designed to make it easier for vehicles behind to notice when the front vehicle is braking, thereby preventing rear-end collisions; 2. The dashboard brake indicator light serves to inform the driver when the rear brake lights are activated.

How many months does it usually take to pick up a Rolls-Royce after ordering?

It usually takes 6-8 months to pick up a Rolls-Royce after ordering. The reasons for the waiting period are as follows: The vehicle hasn't been produced yet: For some newly launched or highly popular models, the demand exceeds supply, and the manufacturer's production capacity can't keep up. As orders pile up nationwide, customers must wait until the manufacturer completes production before they can pick up their vehicles. The vehicle hasn't arrived at the dealership: Due to the highly unstable automotive market conditions, dealers cannot predict whether a particular model's price will drop tomorrow. To avoid excessive inventory, 4S stores don't stock too many vehicles, which means customers must wait for delivery. Complicated new vehicle procedures: After purchasing a car, staff need to issue invoices, arrange insurance (including compulsory traffic insurance), pay purchase taxes, and apply for temporary license plates. The entire process involves significant uncertainty in timing. If any step encounters issues, the pickup time can be significantly extended.

What Causes the Rattling Noise at the Rear Right of BMW 3 Series on Bumpy Roads?

Possible causes for the rattling noise at the rear right of BMW 3 Series on bumpy roads are as follows: Body noise: This issue is usually caused by insufficient body rigidity, leading to deformation during driving, resulting in friction or vibration between doors and door frames, or friction between steel plates due to welding failure in certain areas. Applying adhesive strips on windows/doors or placing rubber pads at friction points may reduce or eliminate the noise. Engine compartment noise: Various possibilities exist for noises originating here. A sharp belt squeal typically indicates belt slippage. If metallic dry friction sounds occur while the engine is running, this usually suggests damaged bearings in the generator, water pump, or power steering pump. Engine guard noise: Screws on moving vehicle components often become displaced. If frequent noises resembling those from the grille area are heard, besides checking for loose grille components, inspect whether engine guard screws are loose or if there's movement between the guard and chassis. To eliminate such noises, besides tightening screws, consider inserting cardboard-like materials at noise sources.

How many years can a BMW 5 Series last under normal driving conditions?

Under normal driving conditions, a BMW 5 Series can last at least 15 years. According to regulations, the scrapping period for private and non-commercial vehicles is no longer 15 years. After 15 years, as long as the car can pass the annual inspection, it can continue to be driven. Vehicle scrapping period: This refers to a safety inspection system based on the number of seats and the duration of use for vehicles. The regulations have abolished the driving age limit for non-commercial sedans, while setting the scrapping mileage limit for private cars at 600,000 kilometers. Vehicles are exempt from inspection for the first 6 years, inspected annually from 6 to 15 years, and inspected twice a year after 15 years. Only vehicles that pass the annual inspection can continue to be driven on the road. Taxis and ride-hailing vehicles are subject to mandatory scrapping after 8 years. BMW 5 Series: The model dimensions are 4998mm, 1901mm, 1559mm; it uses an inline 6-cylinder gasoline engine.

What to Do if the Drain Plug Threads Are Stripped?

If the oil pan drain plug threads are stripped, you can re-tap them to fit a larger screw or install a threaded insert. More information about dry sump systems is as follows: 1. Introduction: Dry sump technology first appeared in the 1930s and was used in small motorcycles to improve lubrication performance. Over the decades, with the development of motorsports, this technology has become more widely understood and recognized, especially in racing and automotive modification fields. 2. Enhanced Engine Lubrication: Since the oil entering the engine's main oil gallery comes from an oil tank rather than directly from the oil pan, the lubricating oil is of better quality, with higher pressure and more stable flow, thereby improving engine lubrication. This advantage is particularly evident in endurance races.
