What are the reasons for Passat idling shake?

[LondynLynn]

Passat idling shake may be caused by the following reasons: 1. The most common cause of car shaking is a dirty throttle or excessive carbon deposits in the fuel injector. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector will be largely absorbed by the carbon deposits, resulting in an excessively lean air-fuel mixture during cold starts, making it difficult to start. 2. Aging engine components: Car shaking is also related to the aging of engine mounts (also known as engine mounts). Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during engine operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the interior of the car, causing shaking during idling.
