What Causes an Audi Car to Shake?

Audi car shaking can be caused by unstable oil pressure, aging engine components, or severe engine carbon buildup. The specific related introductions are as follows: Unstable Oil Pressure: Abnormal fuel pump supply pressure or incorrect readings and poor performance of the intake pressure sensor can cause body shaking. Check the oil pressure and replace components if necessary. Aging Engine Components: Car shaking can also be related to aging 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 can be transmitted to the steering wheel and the interior of the car, causing shaking during idle. Severe Engine Carbon Buildup: Dirty throttle body or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector can be largely absorbed by the carbon deposits, resulting in a lean mixture during cold starts and making it difficult to start.

Is Washing the Catalytic Converter Effective?

Washing the catalytic converter is effective. Here are the relevant details: Advantages: Washing the catalytic converter is the most effective and thorough cleaning method. Disadvantages: Since it requires complete removal of the catalytic converter, which is time-consuming and labor-intensive, many 4S shops and repair shops do not offer washing (removal cleaning) services. Additive Cleaning: Additive cleaning is similar to using fuel additives; it can be directly added to the fuel tank. Drip Cleaning: This method involves connecting a hose to the engine's vacuum tube and using the negative pressure in the tube to draw the cleaning agent from the drip bottle into the engine. The cleaning agent then cleans the catalytic converter as it passes through the exhaust pipe.

Will the Car Stall When Driving Below 10 km/h in Second Gear?

Driving below 10 km/h in second gear will not cause the car to stall. The methods to determine the correct gear shifting timing are as follows: Upshifting Timing: When the engine has sufficient power, it will emit a dull sound. After upshifting, if there is no lack of power or shaking of the transmission mechanism, and the vehicle speed increases quickly with smooth and natural driving, it indicates the upshifting timing is accurate. Downshifting Timing: When the vehicle speed and engine RPM continue to drop, and you feel the car is losing power with the engine compartment starting to shake, it's time to downshift one gear. If downshifting is done too early, it will cause noticeable jerking, which wastes engine power, increases fuel consumption, and negatively impacts the lifespan of both the engine and transmission.
