Vehicle VIN code, commonly known as the chassis number in Chinese, is a unique set of codes assigned by manufacturers to identify individual vehicles. The VIN plate should be affixed to one of the door hinge pillar, door lock pillar, or the pillar where the door latch engages, near the driver's seat. Here is additional information: 1. Meaning of VIN: The Vehicle Identification Number, abbreviated as VIN and sometimes referred to as the chassis number, consists of 17 alphanumeric characters. It identifies the vehicle's manufacturer, engine, chassis serial number, and other specifications. 2. Characteristics of VIN: To avoid confusion with the numbers 1 and 0, the letters 'I', 'O', and 'Q' are not used. Each VIN is unique and non-repetitive.

The Vehicle Identification Number (VIN) is essentially a car's unique ID, consisting of a 17-character alphanumeric code. When helping a friend pick a used car, I relied on it to uncover accident history and avoid pitfalls. The first three digits indicate the country of manufacture and brand—for example, 'LFV' identifies Volkswagen vehicles made in China. The following six characters are particularly useful, revealing engine type, body style, and even safety feature grades. The last eight digits serve as the production sequence number, akin to a birth certificate number. You can find this code on the lower-left corner of the windshield, door frame, and insurance documents. It's indispensable for routine maintenance, as dealerships use the VIN to match specific parts, and insurers reference it to verify policy details. In cases of recalls or theft, law enforcement also tracks vehicles via this number—so never share it casually with strangers.

After a decade in auto repair, I verify VINs over a dozen times daily. Even for models sharing the Corolla name, 2018 and 2022 versions use completely different parts – accurate component orders require checking model codes via VIN. Last time, a customer scratched their VIN while DIY windshield replacement, causing half-day delays due to readability issues. These 17 digits function like a vehicle's genetic code: the 10th digit indicates model year (U=2020, V=2021); the 8th reveals airbag count. During VIN report checks, I pay special attention to prohibited characters I, O, and Q – counterfeit vehicles often substitute numerals 1 and 0. Modern vehicles now embed VINs in ECU chips, enabling original data retrieval even from totaled wrecks via computer diagnostics.

Always check the VIN report when buying used cars! I learned this the hard way and now I use this trick every time. Spending 30 yuan on a professional platform reveals major accident records, which is way more reliable than the seller's claims. Last time I spotted a seemingly pristine SUV, the VIN report showed it was flood-damaged. Note that different platforms may have varying data sources, so it's best to compare reports from two platforms. During ownership transfer, always verify if the VIN on the windshield matches the registration certificate – pay special attention to letters like B and numbers like 8. Used car dealers dread buyers checking VINs; some odometer-tampered vehicles get exposed through maintenance records in the report. Nowadays you can check it on your phone – just enter the VIN and get the report in five minutes.

Are Audi and Volkswagen engines the same?

Audi engines and Volkswagen engines are the same, but there are differences in some functions and details. The specific differences are as follows: Different systems installed: Audi engines are equipped with the AVS system, while Volkswagen engines are not. The AVS system is Audi's variable valve lift technology. Engines equipped with this system can change the valve lift according to different working conditions. Differences in engine cooling, noise reduction, and heat insulation: Audi is Volkswagen's high-end model, and many optimizations have been made in engine cooling, noise reduction, and heat insulation, which Volkswagen does not have. Different combustion methods: The stratified combustion of Audi engines is a type of lean combustion. This combustion method makes power delivery smoother and fuel consumption performance more perfect, while Volkswagen does not use this technology.

What is the recommended cold tire pressure in summer?

Summer cold tire pressure is normal between 2.2 2.5, with relevant information as follows: 1. Cold tire pressure: The generally recommended cold tire pressure is 2.5, which results in lower fuel consumption and keeps the tire pressure within the safe range of 3.0 during high-speed driving. 2. Tire pressure: Actually, the tire pressure requirements vary for different vehicle models, with different maximum and minimum limits for tire pressure. Even the same tire installed on different vehicle models has different pressure requirements, so the optimal tire pressure is not a fixed value but depends on the specific vehicle model. The standard tire pressure value for each vehicle model is indicated in the user manual, on the inside of the fuel tank cap, or below the B-pillar on the passenger side. Although manufacturers provide the optimal tire pressure value, it should be adjusted according to temperature changes. In summer, when temperatures are higher, it is recommended to reduce the tire pressure by 0.1 0.2, while in winter, when temperatures are lower, it is recommended to increase the tire pressure by 0.1~0.2.

Can You Continue Driving When the Warning Light Comes On?

When the car's warning light comes on, you need to stop immediately for inspection and determine whether you can continue driving based on the inspection results. There are generally two situations when the warning light comes on: A yellow symbol light indicates an engine malfunction. A red symbol light indicates a serious engine malfunction that requires immediate maintenance. For the above two situations, the specific solutions are as follows: Check the oil pressure warning light and the water temperature gauge. If there are no issues with the oil pressure gauge and the water temperature gauge, the car can continue to drive, but you should control the speed and immediately head to the nearest repair shop for maintenance. If the oil pressure gauge and the water temperature warning light come on, it indicates that the car has a clear malfunction. You should pull over immediately and call for assistance.

Carpets can be vacuumed directly; if necessary, use specialized cleaning agents, but ensure they are completely dry afterward. Disinfect and Sanitize: For seat covers and seats, it's best to rinse them with bleach to prevent bacterial growth. The evaporator and blower of the air conditioning system should also be removed and disinfected. An air purifier can be used to eliminate odors inside the car.
