13 Volkswagen sagitar has oil in the throttle.

The wastegate valve or turbocharger is damaged.

1. The wastegate valve is damaged. A wastegate valve is connected to the valve cover of many cars, and the wastegate valve is connected to the throttle inlet hose. If the wastegate valve is broken, there will be oil in the throttle of 13 Volkswagen sagitar, which indirectly causes the engine to burn oil slightly.

2. The turbocharger burns engine oil. Many turbochargers burn oil. This is easy to judge. As long as the intercooler is disassembled and engine oil is found in the pipeline of the intercooler, it means that the supercharger is burning engine oil. If the situation is light, you can use it first. If the supercharger burns too much oil, it should be replaced.
