How often does Audi a6 throttle have to be cleaned?

A6 Audi's throttle cleaning is generally recommended to clean the throttle every 65,438+0 to 20,000 kilometers. But from the use point of view, when to clean the throttle is determined by many aspects, such as the driving environment of the vehicle and the control mode of the EFI engine. If the engine is idling normally and there is no jitter, there is no need to clean it.

If Audi A6 works in a relatively polluted environment (mainly refers to inhalable particulate matter), impurities will soon accumulate on the throttle valve, which will affect the intake of the engine for a long time and need to be cleaned. Audi A6 has strict requirements on the measurement accuracy of air flow. A slight blockage can also cause the engine to work abnormally. But for some American engines, there is no such great response without air flow as the calculation basis.

The main cause of throttle scaling is oil vapor, followed by particles and moisture in the air, that is to say, using qualified air filter and removing crankcase ventilation pipe, throttle scaling will be much slower The crankshaft is built in the crankcase, and the lower side is connected with the oil bottom. The working temperature of this part is about 100~ 180.

In addition, the driving quality of the vehicle can also be used to judge whether the throttle needs cleaning. If the vehicle has idling jitter, high idling for a long time, difficult ignition, slow acceleration response, vehicle jitter when the throttle is released, etc. , is need to pay attention to. This is a direct manifestation of dirty throttle and needs to be cleaned in time.
