What Throttle Body Fits on 1999 Audi 2.8 Automatic Car?
Introduction
The throttle body is an essential part of a car’s engine. It controls the amount of air that enters the engine, which in turn affects the engine’s speed and power. If the throttle body is not working properly, it can cause a variety of problems, including poor performance, stalling, and difficulty starting the engine.
If you are experiencing any of these problems, it is important to have your throttle body checked by a qualified mechanic. If the throttle body needs to be replaced, it is important to use the correct part for your car. The wrong throttle body can cause even more problems, so it is important to do your research before you buy.
What Throttle Body Fits on 1999 Audi 2.8 Automatic Car?
The 1999 Audi 2.8 automatic car uses a 70mm throttle body. This is the same size throttle body that is used on the 2.8 liter V6 engine in the Audi A4, A6, and A8. The throttle body is located on the intake manifold, and it is connected to the throttle pedal by a throttle cable.
When you press the gas pedal, the throttle cable opens the throttle body, which allows more air to enter the engine. This causes the engine to speed up and produce more power. When you release the gas pedal, the throttle body closes, which reduces the amount of air that enters the engine. This causes the engine to slow down and produce less power.
Symptoms of a Bad Throttle Body
There are a number of symptoms that can indicate a bad throttle body. These symptoms include:
- Poor performance
- Stalling
- Difficulty starting the engine
- Rough idle
- Increased fuel consumption

If you are experiencing any of these symptoms, it is important to have your throttle body checked by a qualified mechanic.
