What is the BMW G30?

What are the gears of an automatic transmission?

Automatic transmission gears are introduced as follows: 1. P (Parking gear), the vehicle is braked to prevent movement after stopping and shifting to P gear; 2. R (Reverse gear), which can only be engaged when the vehicle is stopped. For models with a lock button, the button must be pressed to switch; 3. N (Neutral gear), used for temporary parking, such as at traffic lights, while the handbrake should be engaged. This gear is prohibited when going downhill; 4. S (Sport gear), the difference between D gear and S gear is only that the computer switches different shifting programs, so S gear can be switched at any time without causing adverse effects such as damaging the transmission. It is suitable for overtaking but not for high-speed use; 5. D (Drive gear), the commonly used gear, where shifting up or down can be completed by throttle control. D1 (or L gear), D2, and D3 are equivalent to manual transmission's 1st and 2nd gears, 3rd and 4th gears, and 5th and 6th gears, respectively; 6. L (Low gear), when going downhill, shifting to low gear reduces brake braking. When going uphill, shifting to low gear makes climbing more powerful; 7. M (Manual mode), unique to manual-automatic transmission models, allows you to enjoy the fun of manual shifting. The "+" sign indicates upshifting, and the "-" sign indicates downshifting.

What does an exclamation mark on the dashboard mean?

An exclamation mark on the dashboard can be divided into three situations: 1. An exclamation mark inside a circled bracket: Brake pad damage or insufficient brake fluid. The solution is to release the parking brake and check if the brake fluid is insufficient. If it still lights up, go to a repair shop to replace the brake pads. 2. An exclamation mark inside a triangle: External light failure. The solution is to check if the lights are faulty. If there is no fault and it still lights up, it is recommended to go to a repair shop for maintenance. 3. An exclamation mark inside yellow brackets: A problem with the tire pressure of a certain tire. The solution is to observe whether the tire is punctured or leaking. If not, drive at a low speed and look for an auto repair shop, beauty shop, or roadside car wash. These places will have air pumps to inflate the car. Then observe the dashboard again. If the warning light still does not go off, find the settings in the vehicle's central console and perform another tire pressure check. The light will turn off once the check is normal.

Symptoms Indicating the Need for Throttle Body Cleaning?

Symptoms indicating the need for throttle body cleaning include: unstable idle speed with shaking, difficulty controlling throttle at low speeds, hard cold starts, requiring a second ignition attempt, shaking while driving, stalling at idle or low speeds, and increased fuel consumption. In severe cases, it may affect the throttle and air intake sensitivity, causing delayed or incorrect transmission of signals by the ECU, triggering the engine pollution control alarm, or even preventing the vehicle from starting. Methods for cleaning the throttle body: 1. Purchase carbon deposit cleaner from a reliable source. 2. Open the front hood, locate the engine and the air filter tube, loosen the clamp screw on the engine side of the air filter tube—the electronic throttle body is connected to the engine. 3. Spray the cleaner onto the electronic throttle body, wipe with chamois cloth, and repeat the process. Use cotton swabs to clean hard-to-reach areas. 4. Turn the car key to the ON position and continue wiping until the black deposits are completely removed. 5. Let it dry for a while after wiping. 6. Reinstall and tighten the air filter tube clamp to complete the cleaning process.

What Causes Water Vapor Inside Vehicle Headlights?

Vehicle headlights contain water vapor for the following reasons: Temperature changes: When headlights are turned on and during use, they generate significant heat. To ensure normal operation, vehicles release this heat through a vent hose. However, moisture in the air can enter the headlight through this hose and condense on the lens, forming fog. Human factors: Besides weather changes, human factors can also cause fog inside headlights. For example, improper headlight modifications may compromise the seal of the headlight chamber, or when driving through water, the engine and exhaust system—being major heat sources—can cause rainwater to evaporate into steam. Some of this steam may enter the headlight through the vent hose. Improper car washing: Some car owners prefer using high-pressure water jets to clean the engine compartment. If water is not promptly removed after washing and the hood is closed, trapped moisture in the engine compartment may seep into the headlights.
