What is the reason for the Volkswagen Passat's first gear not engaging?

[JuniperDella]

Reasons why the Volkswagen Passat's first gear does not engage: The car temperature is low, and the transmission oil is not fully lubricated. It is difficult to shift into first gear while moving, as the vehicle speed and gear do not match. First gear and reverse gear do not have synchronizers. Gear shifting operation: Depress the clutch pedal—quickly release the throttle—shift to the corresponding gear—match the throttle according to the gear, or do not press the throttle, quickly lift the clutch pedal to the semi-engaged state—gently release the clutch pedal after the clutch is engaged. Gear shifting gesture: When shifting gears, keep your five fingers together, lightly but firmly grasp the gear knob, and use your forearm to guide your hand to shift. Pay attention to shifting with gentle and slow force, not too hard, to avoid shifting into other gears. Always pause in neutral when shifting. If you shift into the wrong gear, don’t panic; you can return to the original gear and shift again.
