Where is the Bora throttle controller?

Bora throttle controller is equipped with a throttle controller at the joint between the engine and the intake hose. The reasons are: 1, improving power by accelerating or decelerating; 2, through its self-regulation, correct the air intake function; 3. The function of controlling the operation of the engine assembly; 4, control the flap, through the work of the sensor, control the size of the air intake, in order to facilitate the promotion of power.

Fault phenomenon of Volkswagen Bora throttle: dirty throttle: vehicle idling jitter; Cold cars don't strike easily; The tachometer pointer is unstable at idle speed (unstable at idle speed).

Cause: Oil vapor is the main cause. When the engine is running normally, there will inevitably be crankcase exhaust gas, especially when using low-grade engine oil, so there will be more. In a particular design, one of the crankcase exhaust systems is connected to the front of the throttle. Congratulations, it is very likely that some hot crankcase exhaust gas may return to the front of the throttle through the small hole. When idling, this hot crankcase exhaust gas gradually cools with the air inlet, and finally the temperature is so low that an oil film is deposited near the throttle. Hehe, this oil film is helpful for further dust absorption and plays a decisive role. On the other hand, another part of the crankcase exhaust system is connected with the throttle valve, which will directly pollute all vacuum tubes, including the fuel regulator. There is another important reason: during driving, high-grade and low-speed are indispensable, and neutral taxiing is essential. At this time, the mixture that may contain hydrocarbons sometimes flows backwards. Carbon deposition is inevitable when high-temperature hydrocarbons come into contact with low-temperature intake system components. This is also a common black mud on the throttle.
