What are the symptoms of a faulty coolant temperature sensor in the Excelle?

Here are the symptoms of a faulty coolant temperature sensor in the Excelle: 1. The temperature gauge needle does not move or points to the highest position. 2. Difficulty starting the engine when cold, because the faulty coolant temperature sensor still shows a hot engine temperature signal during cold starts, and the ECU cannot receive the signal for a richer air-fuel mixture, only providing the engine with a leaner mixture. 3. Increased fuel consumption, unstable idle; difficulty accelerating, even when the throttle is fully pressed, the engine speed does not increase. Below is additional information: 1. When the coolant temperature sensor fails, it often still displays the hot engine temperature signal during cold starts. The ECU does not receive the signal to provide a richer air-fuel mixture and can only supply the engine with a leaner mixture (the signal for a hot engine), making it difficult to start the engine when cold. 2. Most automotive coolant temperature sensors are made using NTC thermistors. The vehicle's computer receives the resistance value transmitted by the NTC. Therefore, whether the sensor 'fails' due to a short circuit or an open circuit, the vehicle's computer will receive either a resistance of 0 or an infinite resistance. In both cases, the vehicle's computer will determine that the temperature sensor has malfunctioned. The malfunction indicator light will stay on or be accompanied by an alarm sound, and the vehicle will forcibly reduce the intake air volume and fuel injection quantity, lowering the engine's operating speed to avoid unnecessary damage and wear caused by engine overheating.

Where to Find Tire Size Information

Vehicle's original tire size can be found in the owner's manual, on the edge of the left front door, on the storage compartment door or fuel filler cap. You can also locate tire specification information on the sidewall of existing tires. Here's partial introduction about tire specifications: 1. There are multiple representation methods for tire specifications, with four most common types in the market: British, German, metric and American standards. 2. Tire types follow international standard tire codes, expressed in millimeters for section width and aspect ratio percentage, followed by tire type code, rim diameter, load index and speed rating symbol.

How Often Should Vehicles Be Inspected After the 6-Year Exemption?

After the six-year exemption from inspection for motor vehicles, those over 6 years old must be inspected once a year. According to the relevant provisions of the "Regulations for the Implementation of the Road Traffic Safety Law": Article 16. Motor vehicles should undergo safety technical inspections within the following periods from the date of registration. The documents required for vehicle annual inspection include the vehicle's driving license, valid compulsory insurance policy, the owner's ID card, and all traffic violation records must be cleared in advance. Safety technical inspections should be conducted within the following periods: Operational passenger vehicles must be inspected once a year within 5 years; those over 5 years old must be inspected every 6 months. Trucks and large or medium-sized non-operational passenger vehicles must be inspected once a year within 10 years; those over 10 years old must be inspected every 6 months. Small and mini non-operational passenger vehicles must be inspected once every 2 years within 6 years; those over 6 years old must be inspected once a year; those over 15 years old must be inspected every 6 months. Motorcycles must be inspected once every 2 years within 4 years; those over 4 years old must be inspected once a year. Tractors and other motor vehicles must be inspected once a year. Operational motor vehicles that pass safety inspections within the specified period. Therefore, non-operational motor vehicles are exempt from inspection for the first six years, then inspected once every two years from 6 to 10 years, and vehicles over 10 years old must be inspected once a year, while those over 15 years old must be inspected every 6 months. Vehicle annual inspection mainly includes the following items: Appearance inspection: Mainly checks vehicle lights, body appearance, suspension, sunroof, and tires. It verifies if the lights are functioning normally, if there are any non-working lights, if the body color has been changed, or if the suspension has been modified. Emission inspection: Checks whether the tailpipe emissions meet national standards during high-speed operation. On-road inspection: Primarily examines the vehicle's braking system, headlights, horn, and chassis. Violation check: All traffic violation records must be cleared before the annual inspection to pass. Vehicle annual inspections can be conducted up to 90 days in advance but must not be overdue. According to Article 47, Paragraph 4 of the "Motor Vehicle Registration Management Measures," vehicles that fail to undergo safety technical inspections within the specified period will be warned or fined by the public traffic management department. Only after paying the fine can the annual inspection be conducted. Consequences of failing to inspect on time include: Vehicles that do not undergo annual inspection on time are not allowed on the road. Driving a vehicle without timely annual inspection results in 3 penalty points and a fine. If an uninspected vehicle is involved in a traffic accident, the owner bears full or primary responsibility, and the insurance company will not compensate. Driving without timely annual inspection is considered illegal and may result in vehicle impoundment.

What are the symptoms of a faulty diesel injector?

Diesel injector damage mainly manifests in the following aspects: 1. Engine vibration: When the car's injector is damaged and fuel injection is not smooth, the engine will exhibit symptoms such as operational vibration during operation. 2. Decreased power and increased fuel consumption: As the injector is damaged, the fuel injection volume and pressure cannot be guaranteed, leading to symptoms like reduced vehicle power and increased fuel consumption. 3. Increased exhaust emissions pollution: Faults in the engine injector will inevitably affect the mixing and combustion of the combustible gas mixture, thereby increasing the pollutants in the vehicle's exhaust emissions.

What is the fuel consumption of the Volkswagen Sharan?

The average fuel consumption of the Volkswagen Sharan is 12.3 liters per 100 kilometers. Vehicle condition: In addition to regular cleaning, it is important to pay attention to the vehicle's condition, perform regular maintenance, and carry out timely repairs. Driving habits: Poor driving habits can lead to unnecessary fuel wastage, such as carrying excessive unnecessary weight, driving with windows open at high speeds, sudden acceleration, and hard braking, all of which can increase fuel consumption. Road conditions: Driving in urban conditions can increase fuel consumption by 20% compared to test track conditions, mainly due to frequent starts and stops, waiting at traffic lights, and gear changes for acceleration and deceleration, all contributing to higher fuel consumption.
