Audi A4 instrument displays sD00-00-0. What does that mean?

Audi A4L instrument displays sD00-00-0, indicating that the automobile throttle is faulty.

To solve this problem, you must go to a professional auto repair shop to clean the accelerator and then troubleshoot the fault code.

Throttle classification:

There are two kinds of throttles: traditional cable throttle and electronic throttle. The traditional engine throttle control mechanism works by pulling a cable (soft steel wire) or a pull rod. One end of the cable is connected with the accelerator pedal, and the other end is connected with the accelerator linkage plate. The electronic throttle mainly uses the throttle position sensor to control the throttle opening according to the energy required by the engine, so as to adjust the intake air.

How to clean and prevent should pay attention to:

1, which should be dismantled and cleaned up.

2. Correct some misunderstandings of cleaning the throttle.

3. The fouling of the throttle is mainly engine oil vapor, followed by particles and moisture in the air. That is to say, using a qualified air filter and removing the crankcase ventilation pipe, the fouling speed of the throttle will be much slower.
