The yellow key light displayed on the Teana dashboard indicates that the car cannot detect the key. This situation mostly occurs in vehicles with one-button start systems, as starting the vehicle usually doesn't require turning a key. Therefore, placing the key on your person or somewhere in the car might cause the engine to fail to properly receive and detect the key data, triggering this alert. It could also be due to a dead battery inside the key, or damage to the car's receiving module or the key's transmitting module. If this happens, you should take the vehicle to a professional institution or a 4S shop for inspection. If the issue is a dead key battery, simply replacing the battery should resolve it.

BMW 5 Series Air Conditioning Vibration Solution?

When a BMW 5 Series experiences vibration after turning on the air conditioning, it is necessary to consider fuel system issues. The idle speed with air conditioning on requires stable combustion, and the computer adjusts the fuel injection and air intake to maintain stable air-fuel mixture. This indicates a dirty fuel system or low fuel atomization efficiency. The specific solutions are as follows: 1. Air Conditioning Idle Speed Booster: Most vehicles are equipped with an engine air conditioning idle speed booster. When the air conditioning compressor is operating, the air conditioning system simultaneously sends a command to increase the engine speed to the required range, solving the issue of engine vibration when the air conditioning is on. 2. Check the Circuit and Adjust the Idle Speed Device: If the vehicle is not equipped with an idle speed booster, installing one is recommended, as it is not expensive. If the vehicle comes with this device from the factory, simply check the circuit and adjust the idle speed device.

What to Do When There's a Clunk Sound When Shifting Gears in an Automatic Transmission?

The solution to a clunk sound when shifting gears in an automatic transmission is to have it inspected and repaired at a car repair shop as soon as possible. The specific reasons for the clunk sound when shifting gears in an automatic transmission are as follows: 1. Shifting gears without stopping the car completely: If the car is not completely stopped before shifting to P gear, the P gear lock hook inside the transmission will hit the gear, producing a clunk sound. This operation can cause the lock hook to wear or even break, and in severe cases, it may lead to the transmission being scrapped. 2. Incorrect operation sequence when parking on a slope: For automatic transmission models, the P gear relies on the lock hook to engage the gear to keep the car stationary. When parking on a slope, the handbrake should be engaged first before shifting to P gear, allowing the handbrake to bear the vehicle's sliding force. 3. Malfunction in the gear shift mechanism: Many automatic transmission models with gear levers actually use mechanical structures to shift gears. Over time or due to corrosion, the connecting parts of the gear shift mechanism can become loose or stuck, resulting in noise when shifting gears. 4. Wear and tear of transmission gears: The gears in the transmission mesh very tightly, but because of this tight meshing, wear and tear are inevitable. Over time, larger gaps will form between the gear teeth, causing noise when shifting gears.

What are the reasons for the failure to start the parking generator?

The reasons for the failure to start the parking generator are as follows: 1. Ignition plug damage: Use a multimeter to check the resistance value between the two leads of the ignition plug. The resistance value should be between 0.6-1.2 ohms. If it is not within this range, the ignition plug needs to be replaced. 2. Heater overheating: If the heater is overheating while the radiator and defroster are not heating, possible causes include blockages in the circulation pipeline; bent rubber hoses; water pump failure; gas in the circulation water circuit; inlet and outlet valves not being opened; the engine thermostat opening too early, etc. Identify the cause and carry out the corresponding repairs.
