What Causes the Body Shaking of Audi A6?
1 Answers
Tire imbalance, ignition system issues, fuel system problems, and clogged fuel injectors can all cause the body of an Audi A6 to shake. Below are solutions for these four situations: 1. Tire Imbalance: The first possible cause is poor tire balance. It's necessary to perform a four-wheel alignment and dynamic balance as soon as possible. If the vehicle doesn't pull to one side, a dynamic tire balance may suffice. 2. Ignition System Issues: During a cold start, the engine requires a richer air-fuel mixture, which in turn needs higher ignition energy. If the spark plug gap is too large, or if the ignition coil or high-voltage coil is aging, it can lead to reduced ignition energy, causing the body to shake. 3. Fuel System Problems: Fuel system issues are generally caused by blockages in the fuel lines, leading to poor fuel supply. Symptoms include engine shaking, unstable idling, and stalling while driving. Additionally, a faulty fuel pump can also cause engine shaking. To diagnose a fuel pump issue, disconnect the fuel line and check the flow rate and volume of fuel. 4. Clogged Fuel Injectors: The fuel injectors in an electronic fuel injection vehicle are critical components for fuel delivery and have a long service life, potentially lasting hundreds of thousands of kilometers. However, deposits in gasoline can clog the injector nozzles, causing inconsistent fuel spray among injectors. This leads to uneven cylinder operation and engine shaking. The solution is to remove and clean them.
