What causes intermittent idling vibration in the Audi Q5?

[SanVivian]

Audi Q5 intermittent idling vibration may be caused by the following reasons: 1. Dirty air filter: The air filter protects the engine from wear and is usually replaced every 10,000 kilometers. If not replaced in time, insufficient air intake may cause low idle speed, resulting in engine vibration. 2. Clogged fuel injectors: Fuel injectors are key components for fuel injection and have a long service life, reaching hundreds of thousands of kilometers. However, gum deposits in gasoline can clog the injector nozzles, causing inconsistent fuel injection among injectors, uneven cylinder operation, and engine vibration. 3. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor ignition system performance or weak spark plug firing can also lead to such faults. 4. Unstable fuel pressure: If you have already cleaned the engine carbon deposits, throttle body, replaced gaskets and spark plugs, but still experience body shaking at idle.
