How to Match the Throttle Body of an Audi A4?

[LeTyler]

Audi A4 throttle body matching requires the use of a specialized computer-guided throttle body matching function. Below is more information about the throttle body: 1. Function of the car throttle body: It controls the air intake and automatically regulates the fuel quantity through the throttle position sensor. In other words, it is the device that controls the throttle. 2. Classification of car throttle bodies: One type is controlled by a cable, known as a semi-mechanical semi-electronic throttle body, while the other type operates via sensor signals, known as a fully electronic throttle body, where the throttle opening angle is calculated by the computer based on intake volume and sensor angle. 3. The throttle body is a controllable valve that regulates air entry into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to produce power. It connects to the air filter at the top and the engine block at the bottom, earning the nickname 'the throat of the car engine.'
