Volkswagen Golf - Video tutorial

Model: Volkswagen Golf MK 4, Golf IV, Golf 4 - Years 1997-2003
Part: Checks and maintenance
Operation: Diagnosis and repair of the failure in the secondary air injection system

The secondary air injection system serves to reduce harmful emissions, allowing further combustion of the engine exhaust gases, precisely by injecting the comburent, which is useful for breaking down these gases. Having a diagnostic software available, you connect to the car socket and check the data of the house with those found in the measurement: once anomalies are found, a physical analysis is carried out on the system. A vacuum condition is created by a valve in the circuit and its tightness is checked. If the vacuum is not maintained, it means that there is a leak in the circuit and at this point look for leaks in the pipes. Once the damaged and replaced pipes have been found, a new check is carried out with the aid of the software: if the data found conforms to those declared, the problem is solved.
