How to Check the Production Date of a Car from the Windows?

Here are the methods to check the production date of a car from its windows: 1. There is usually a code at the bottom left or right corner of the car window. The last row of the code consists of a number and several black dots, which represent the production date of the glass. 2. The number in the code indicates the production year, while the black dots represent the production month of the glass. 3. The production year of the glass should be interpreted in conjunction with the car's manufacturing date: For example, if the number in the last row is 8, and the car was manufactured in 2007 or 2008, then the glass production year can be deduced as 2008. 4. The production month of the glass is determined by the position of the black dots: If the dots are in front of the number, subtract the number of dots from 7; if the dots are behind the number, subtract the number of dots from 13. The result is the production month of the glass.

Which car is the PHIDEON?

PHIDEON is a mid-to-large-sized sedan released under the Volkswagen brand, with the Chinese name "Hui Ang". Below is the relevant introduction to the Hui Ang: 1. The overall body design follows the design concept of the previous CCoupe concept car, featuring Volkswagen's family-style front design where the front grille integrates with the LED headlights and extends to the sides of the body. The side waistline runs through the entire body and extends to the top of the taillights. The Hui Ang's taillights adopt a double-layer design, with the lower layer taillights contracting inward to create a staggered effect. 2. The name PHIDEON originates from the Roman goddess "Fides", symbolizing vows and faith. PHIDEON will be Volkswagen's first mid-to-large-sized car, bridging the market gap between the Phaeton and the Magotan. 3. PHIDEON is built on the MLB platform, a luxury car platform from the Audi brand. After the discontinuation of the Phaeton, this car will become the flagship sedan of the Volkswagen brand. The SAIC Volkswagen PHIDEON is built on the same platform as the Audi A6, with dimensions of 5050mm/1870mm/1480mm (length/width/height) and a wheelbase exceeding 3000mm, making its body size very close to that of the domestically produced A6L.

How Often Should the Spark Plugs of SAIC Volkswagen Lavida Hatchback Be Replaced?

Under normal maintenance conditions, the spark plugs of SAIC Volkswagen Lavida Hatchback should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. You can refer to the following standards for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and clean them thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage wires in the firing order and secure the cover.
