What happened to the epc light on Jetta dashboard?

If the EPC fault light appears, it indicates that there is something wrong with the engine power control management system. The main reasons for this problem are as follows:

The first one is that the brake lights don't work. When the brake light of our vehicle is not on, the EPC fault light will appear.

Second, the throttle fails. If there is something wrong with the throttle or wiring of the engine, EPC will also light up.

Third, the brake switch is damaged. If the brake switch is damaged and fails due to excessive wear, EPC will also appear.

The fourth is that the clutch switch is broken. Like the brake switch, EPC will appear when the clutch switch is broken.

What's the problem? I suggest you use the maintenance computer to check and find the problem according to the fault code.
