Why is the Audi car shaking?

[OBriella]

Audi car shaking may be caused by the following reasons: 1. Unstable oil pressure: Abnormal fuel pump supply pressure or incorrect readings and malfunction of the intake pressure sensor can cause body shaking. Check the oil pressure and replace components if necessary. 2. Aging engine components: Car shaking is also related to the aging of engine mounts. Engine mounts are essentially the shock absorption system of the engine, responsible for absorbing minor vibrations during operation. If the engine mounts fail, these vibrations will be transmitted to the steering wheel and the cabin, causing shaking during idle. 3. Severe engine carbon buildup: Dirty throttle body or excessive carbon deposits on the fuel injectors. 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 overly lean air-fuel mixture during cold starts and making it difficult to start.
