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.

I've been driving an Audi A4 for several years and have encountered shaking issues multiple times, mainly noticeable during low-speed driving or idling when the body shakes severely. Common causes include engine misfire: aging spark plugs, damaged ignition coils, or high-voltage line issues leading to a cylinder not working properly; also, tire imbalance: slight wheel rim deformation or improper dynamic balancing, which causes more bumpiness at high speeds; aging suspension components like leaking shock absorbers or worn control arms can also cause this. When dealing with it, I check the tire appearance and engine sound myself, but a real diagnosis requires professional tools. Audi cars are precise, and carbon buildup can lead to restricted airflow, increasing shaking—long-term city driving makes this more likely. It's recommended to clean carbon deposits and replace spark plugs during regular maintenance to extend the vehicle's lifespan. Don’t delay; if the problem worsens, it could affect safety. Find a reliable 4S shop or specialized repair shop to scan for fault codes—it costs some money but ensures peace of mind.

Every time my car shakes, it gives me a headache, and I usually head to the repair shop. Start with simple checks: Are the spark plugs burnt out? Audi's ignition plugs have a short lifespan. Check the tires for bulges, missing balancing weights, or incorrect tire pressure. A clogged air filter restricting airflow can also cause shaking. Worn engine mounts amplify engine vibrations, especially since Audi parts are expensive—minor repairs can be painful. From my experience: unstable idling is often due to fuel system or injector issues, while shaking while driving usually points to wheels or suspension. For safety, if the car shakes at high speed, slow down and pull over immediately to check the wheel temperature. Find a trusted mechanic to plug in an OBD scanner and read the codes—it saves money on guesswork. During regular car washes, pay attention to the chassis condition and replace filters promptly to avoid carbon buildup.

I understand car shaking from too many modifications. An Audi shakes badly if the wheels aren't balanced properly after changing rims, or if the suspension mods have incompatible shocks causing noticeable vibrations. Factory issues like carbon buildup can cause idle shaking, while warped brake discs wobble when braking. Driveshaft looseness or differential faults get worse at high speeds. Recommend checking compatibility of all modified parts, especially chassis and wheel offset. Unadjusted ECU leads to unstable engine output - try higher octane fuel to reduce knocking. High-performance builds lose driving fun if shaking affects handling - careful tuning is crucial.
