Does the new Passat need to be initialized after cleaning the throttle?

The new Passat does not need to be initialized after cleaning the throttle.

The main function of the throttle valve is to control the air intake according to the load of the engine, and how often it is cleaned is determined by many aspects. Such as the driving environment of the vehicle and the control mode of the EFI engine.

If the vehicle works in a polluted environment (mainly inhalable particles), impurities will accumulate on the throttle valve soon, which will affect the intake of the engine for a long time, so it needs to be cleaned. This phenomenon is most obvious when starting the vehicle.
