Throttle actuator of the KE-III-Jetronic injection system (Audi 100 C4)

Basically, the throttle actuator is quite sensitive. When working in the engine compartment, you need to make sure that the "gas" rod does not break. Although the passage of the "gas" rod in engines is different, their operating principle is the same. In some engines, the rod passes under the fuel line, while in others it is connected directly next to the expansion tank of the cooling system.

It rarely happens that the "gas" rod needs to be replaced, but it needs to be disconnected for some work. To do this, you need to:

Disconnect the support and unhook the end of the "gas" rod from the segment on the throttle body (reinforced with a mounting bracket). The gas rod is attached to the support using a mounting bracket, which should not be removed.

After installing the support and connecting the end of the rod, the assistant should press the gas pedal and check that the throttle segment cannot move more than 1 mm.
