What are the reasons for the failure to start due to brake malfunction in Golf 7?

[VonIsla]

Here are the reasons why Golf 7 may fail to start due to brake malfunction: 1. Excessive carbon deposits: This starting issue may be caused by excessive carbon buildup in the idle speed motor, intake tract, intake valves, and combustion chamber. The accumulation of carbon deposits and dirt in the intake tract alters the cross-sectional area of the air passage, resulting in an overly rich or lean air-fuel mixture. This can lead to abnormal combustion, engine shaking after starting, or even failure to start. 2. Fuel injector leakage: Problems with the fuel injector, such as leakage or excessive carbon deposits, can cause a lean air-fuel mixture during startup, making it difficult to start. 3. Charcoal canister solenoid valve: Malfunctions in the charcoal canister or its solenoid valve can also lead to difficulties in starting.
