Car abnormal noises mainly include engine abnormal noises, brake abnormal noises, and abnormal noises from other parts of the vehicle body. Engine abnormal noises: If there is abnormal noise from the belt, it is generally caused by belt slippage. If a hissing sound is heard, it is most likely due to blockage or breakage in the intake system or vacuum tube. Additionally, abnormal noises caused by friction of external metal accessories during engine operation may be due to damage to components such as the generator or water pump. Brake abnormal noises: The most common source is abnormal noises from the brake pads. A sharp friction sound during braking is mostly caused by foreign objects like sand in the brake disc or rust on the brake disc. Try pressing the brakes a few more times to eliminate the noise. Also, check if the brake pads are worn or have exceeded their service limit.

Can someone else apply for ETC on behalf of the vehicle owner?

It is possible to apply for ETC even if you are not the vehicle owner. According to the "Implementation Plan for Accelerating the Application of Electronic Toll Collection (ETC) on Highways" issued by the Ministry of Transport, the following documents are required: the original valid ID card of the vehicle owner, the original and a copy of the vehicle registration certificate (showing the most recent annual inspection stamp), and if applying on behalf of someone else, the original valid ID card of the proxy applicant. If applying through major bank branches, a debit or credit card from the corresponding bank is also needed. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding with a debit card. ETC Deduction Principle: Highways have one or more ETC lanes. Using dedicated short-range microwave communication between the vehicle's on-board unit (OBU) installed on the windshield and the microwave antenna in the ETC lane, the system connects with the bank's backend for settlement, allowing vehicles to pass toll stations without stopping. This operates on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the need to queue and wait. Green and eco-friendly: Reduces noise and exhaust emissions by avoiding idling at toll booths. Cost-saving: Reduces wear and tear, fuel consumption, and offers a 5% discount on toll fees. Improved efficiency: ETC lanes can theoretically process vehicles 2-3 times faster than traditional methods, making them faster and more technologically advanced. Compared to license plate payment, ETC is more mature and advantageous. Policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transportation System" aims for widespread ETC adoption by 2020, targeting 50% usage among passenger vehicles. Future possibilities: Beyond increasing ETC convenience and adoption rates, future plans include promoting ETC for trucks and integrating ETC with vehicle-to-vehicle and vehicle-to-infrastructure communication for smart transportation. ETC Usage Notes: The ETC sensing range is 8 meters. If the vehicle ahead stops, maintain a distance of over 10 meters to avoid accidental deductions for the wrong vehicle. The ETC lane recognizes vehicles at speeds up to 20 km/h. Excessive speed may cause reading failures. Tampering with or moving the OBU device, or if the ETC tag becomes loose or detached, may deactivate it. Non-intentional issues can be resolved by reactivation at the issuing bank or highway service center. Insufficient balance on a debit card linked to ETC may cause payment failure. Follow staff instructions to use cash or card in manual MTC lanes. Thick or modified windshields may interfere with ETC signal reception, especially after repairs or replacements.

What type of engine oil does the Nissan Teana use?

Nissan Teana typically uses 0W-30 full synthetic engine oil. Engine oils are categorized into three types, with differences as follows: 1. Mineral oil: A commonly used lubricant in the market. Essentially, it utilizes the inferior components of crude oil. Mineral oil is inexpensive, but its service life and lubrication performance are inferior to synthetic oils, and it also causes significant environmental pollution. Additionally, mineral oil cannot completely remove impurities during the refining process, resulting in a higher pour point, making it unsuitable for use in extreme low-temperature conditions. 2. Semi-synthetic oil: A product purified from mineral oil through hydrocracking technology. It is a mixture of mineral oil and full synthetic oil in a 4:6 ratio. The purity of semi-synthetic oil is very close to that of full synthetic oil, but its cost is slightly higher than mineral oil, making it an ideal transitional product from mineral oil to synthetic oil. 3. Full synthetic oil: Full synthetic oil is a high-grade product among engine oils. It is derived from ethylene and propylene dispersed from natural gas or gas in crude oil, which are then subjected to complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules. In essence, it uses the superior components of crude oil, undergoes chemical reactions, and achieves the desired molecular structure under human control. Full synthetic oil molecules are neatly arranged, with strong resistance to external variables, excellent thermal stability, oxidation resistance, and viscosity change resistance compared to mineral and semi-synthetic oils, but it is also the most expensive.

How many cylinders does the Tiguan L use?

The Tiguan L is equipped with the EA888 engine, a four-cylinder engine. Below is additional information about the EA888 engine: 1. The EA888 engine is a newly designed engine by Volkswagen, belonging to the third generation. It integrates advanced technologies such as direct injection, turbocharging, and variable valve timing, achieving a balance between power and fuel efficiency. 2. The EA888 series includes two displacements: 1.8L and 2.0L. The mechanical structures of these two engines are fundamentally the same, with differences in the length of the connecting rods and the crankshaft radius. The 2.0TSI has shorter connecting rods and a larger crankshaft radius compared to the 1.8TSI to increase displacement. 3. The piston top structures of the two engines differ, primarily to adjust the working volume of the combustion chamber, ensuring a consistent compression ratio and achieving the same combustion effect.

Where is the oil filter located on the Tiggo 8?

The oil filter of the Tiggo 8 is located under the engine, in front of the oil pump. Here is some extended information about oil filters: 1. The oil filter ensures the cleanliness of the oil in addition to filtration. 2. If the oil bypasses the oil filter, it can reduce the engine's service life. 3. The function of the oil filter is to remove impurities, gums, and moisture from the oil, delivering clean oil to all lubrication points. The replacement frequency for the oil filter is as follows: 1. For frequent car use, the oil filter should be replaced every 8,000 km. 2. Under harsh conditions, such as frequent driving on dusty roads, it should be replaced every 5,000 km.

What is the issue when the EPC light is on in a Volkswagen?

EPC indicator light staying on indicates a fault in the engine or electronic system. If the light remains on or flashes after ignition or during driving, it means the management system has detected a fault in the engine or electronic system. Please contact a service station immediately. Below are the solutions for a continuously lit EPC indicator light: 1. Troubleshoot the intake system, use fuel that meets standards, and clean the throttle body; 2. Remove carbon deposits and clean related parts; 3. Rewrite the ECU-related data. Below are the causes of EPC electronic throttle system faults: 1. Intake system faults, such as leaks or blockages; 2. Dirty throttle body with excessive carbon deposits; 3. Use of substandard fuel; 4. Abnormal cylinder pressure, poor operating conditions; 5. Valve faults, sticking or carbon deposits, etc.; 6. ECU faults; 7. Sporadic faults, false alarms.
