What is the reason for the jerking in Volkswagen Sagitar?

[Colton]

Volkswagen Sagitar jerking is caused by engine oil passage blockage. Engine oil passage blockage: First, focus on the engine. If the car experiences jerking while driving, the engine is definitely involved. The engine's ignition, intake, and fuel injectors collectively determine fuel combustion, which is also the power source of the engine. If the intake volume decreases, ignition weakens, or the fuel injection reduces, the power will be insufficient, resulting in a jerking sensation. Other situations that cause jerking: Jerking during the start of an automatic transmission car is normal. If you want to accelerate quickly while driving, you need to press the accelerator pedal deeply. At this time, the automatic transmission will automatically downshift to increase the engine speed. When the speed reaches a certain level, it will upshift. After upshifting, the speed will drop significantly, resulting in a relatively obvious jerking sensation. This situation often occurs in automatic transmission models with fewer gears, such as 4-speed automatic models. After starting an automatic transmission vehicle, if you want to drive smoothly, you can lightly press the accelerator pedal at the appropriate time, and the transmission will upshift automatically, with a weaker shifting jerking sensation. If you want to maintain good acceleration performance, you need to press the accelerator pedal deeply, and the automatic transmission will upshift to a higher gear at a higher speed, resulting in a more noticeable shifting jerking sensation.
