Did Audi clean the throttle well?

Audi A6 throttle cleaning steps: Audi A6 should not clean the throttle immediately after parking, because the temperature in the cabin is high, which may burn the skin. It is suggested to stop for a while until the engine room temperature drops. It is necessary to determine the position of the throttle valve before cleaning. The throttle valve is behind the air inlet, so it is not far to find the air filter. Every car will be in a different position. The throttle of some models will be covered by the engine cover plate, so it will be more intuitive to open the cover plate for inspection. Open the cover of Audi A6 engine, and you can clearly see the position of the throttle. To remove the throttle valve, you must first remove the hose connecting the air cleaner and the throttle valve. Both ends of the hose are fixed with circular iron hoops, and the iron hoops are fixed with screws. Loosen the screw to pull out the hose. After the screw is loosened, hold one end of the hose with both hands and pull it back hard, and the hose will be removed. Some automobile hoses may not be easily disassembled or installed firmly, so they are not easy to disassemble. Don't pull them hard, it will easily damage the hose. You can try to twist them left and right at the same time, and then push back hard after the whole is loose. You can see the throttle when the hose is lowered. At this time, the periphery of the throttle is generally not dirty, but it is really dirty inside. If you want to see the situation inside, you need to unscrew the key door and open the vehicle, but it won't stop. After stepping on the accelerator pedal, the accelerator will be opened, and you can clearly see that there will be brown dirt inside the accelerator. @20 19
