The yellow triangle exclamation mark warning light is a general fault indicator. It may illuminate under the following circumstances: 1. Overheating of the dry dual-clutch transmission clutch; 2. Fuel cut-off system intervention or malfunction; 3. Parking sensor failure; 4. Fault in exterior light bulbs; 5. Engine oil pressure sensor malfunction; 6. Traction control system warning or failure. Other dashboard indicators with exclamation marks include: 1. An exclamation mark inside parentheses indicates the tire pressure monitoring light. It illuminates during ignition for system check and should turn off after a few seconds. Continuous illumination or flashing indicates abnormal pressure in one or multiple tires; 2. An exclamation mark inside a light symbol represents the exterior lighting fault indicator, signaling malfunctioning exterior light bulbs when illuminated.

When I see the yellow triangle exclamation mark light up, I know the vehicle is issuing a general warning signal. It's commonly called the master warning light, indicating a problem with a certain system but not specifying exactly where the fault lies. Common causes include low tire pressure, brake system issues such as low brake fluid level, sensor false alarms, or other electronic problems. If this light appears while driving, the best course of action is to slow down, pull over safely, and check the dashboard for other warning lights, such as the engine light or tire pressure warning light. If the tire pressure is low, it might be a puncture requiring repair; if it's a system issue, try restarting the car to see if the light disappears. Safety first—don't ignore this warning as it can lead to more serious risks like a tire blowout or brake failure. It's recommended to seek professional inspection as soon as possible.

Can I customize my own license plate number?

Yes, you can customize your own license plate number. Online license plate selection is divided into two types: 1. Custom number selection: Simply put, you can choose the numbers you want. Each time you can input 5 numbers, with a total of 5 attempts, meaning 25 license plate numbers. However, if the desired number is slightly better, it's basically useless as you won't get your preferred license plate, making it somewhat of a gimmick. 2. Online random selection: This involves clicking the random button online, which will generate 10 random license plate numbers. You have 5 random attempts, totaling 50 chances to select a random license plate. It's important to note that each random page will have one pre-selected license plate, with 5 pre-selection opportunities across five pages. After completing the five random pages, you can then confirm your license plate number from the 5 pre-selected options.

What transmission does the Volkswagen Bora use?

The transmission brand used in the Volkswagen Bora is Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions, holding the top global market share in the automotive automatic transmission sector. The Bora is equipped with a 7-speed wet dual-clutch transmission, a 5-speed manual transmission, or a 6-speed automatic manual transmission (Tiptronic). The automatic manual transmission is essentially a traditional AT or CVT transmission with added manual shifting functionality. When using the Bora's transmission in daily driving, pay attention to the following points: Do not delay transmission fluid changes for extended periods. Prolonged intervals between fluid changes can damage internal components such as bearings and the transmission housing. Avoid prolonged coasting in neutral. While many experienced drivers coast in neutral when driving manual transmission vehicles, doing so in automatic transmission models can cause overheating and create a noticeable jolt when shifting back to Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle has come to a complete stop. Some drivers attempt to demonstrate smooth operation by shifting into reverse while still moving forward, which causes significant gear wear and can lead to gear grinding failures over time. Avoid frequently climbing steep slopes in Drive (D). Automatic transmission vehicles may overheat under high loads or upshift prematurely when tackling steep inclines. In such situations, use manual mode to maintain lower gears or engage sport mode to protect the transmission. Do not tow over long distances. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck with the transmission in Neutral (N). Never use tow ropes or attempt to tow the vehicle directly with another vehicle.
