Does Audi clean the throttle or change the oil first?

Audi cleans the throttle first. When the idle speed of our car is unstable, it may mean that the throttle of our car needs cleaning. Some cars will also have external manifestations such as starting difficulties and even power drop, so it is necessary to clean the throttle. Purchased cleaning agents are generally very corrosive, which may easily lead to excessive corrosion of rubber ring or oil seal during cleaning, leading to unstable idle speed, and excessive cleaning of throttle will also lead to premature scrapping of throttle.

Working principle of Audi's first throttle valve

The driver manipulates the accelerator pedal, and the accelerator pedal position sensor generates the corresponding voltage signal and inputs it to the throttle control unit. The control unit firstly filters the input signal and communicates with the vehicle control unit through CAN bus to obtain other working condition information and various sensor signals, such as engine speed, gear position, throttle position, air conditioning energy consumption, etc. So as to calculate all the torque required by the vehicle, and obtain the optimal throttle opening by compensating the expected throttle opening.
