How often does the Magotan throttle have to be cleaned?

How often does the Magotan throttle have to be cleaned? The following is my personal opinion:

Magotan throttle is cleaned every 20,000 kilometers. Throttle is a controllable valve that controls air to enter the engine. There are two kinds: traditional cable throttle and electronic throttle. After the gas enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, which will be burned to do work. It connects the air filter at the top and the engine cylinder at the bottom, and is called the throat of the automobile engine. Take Magotan 2020 330TSIDSG luxury car as an example: it is a medium-sized 4-door 5-seat car with 7-speed wet dual-clutch gearbox, with the length, width and height of 4865mm, 1832mm, 147 1mm, the wheelbase of 287 1mm and the top speed of 2650.
