What Causes Severe Engine Vibration in Audi Cars?

[Trenton]

Severe engine vibration may be related to excessive carbon deposits, ignition system malfunctions, and other reasons. Below is an analysis of the causes of engine vibration: Severe engine carbon deposits: When there is excessive 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. Ignition system issues: Check the working condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or improper spark plug firing can also lead to such fault symptoms. Aging engine components: Engine vibration in cars is also related to the aging of engine mounts (also known as rubber mounts).
