Why does the Passat B5 have poor acceleration?

[VonHenry]

The reasons for poor acceleration in the Passat B5 are as follows: 1. Clutch slipping: The most obvious symptom of clutch slipping is that the engine speed rises quickly, but the vehicle speed does not increase, resulting in a noticeable feeling of poor acceleration. If clutch slipping occurs, it is recommended to promptly visit a 4S shop or a professional repair shop for inspection and repair. Depending on the situation, appropriate lubrication or repair should be performed, and in severe cases, the clutch should be replaced immediately to ensure driving safety. 2. Engine oil issue: If low-viscosity engine oil is used or the oil viscosity is too high, the engine's operating resistance increases, leading to throttle lag, poor acceleration, and increased fuel consumption. Solution: Replace with higher-viscosity engine oil.
