EPC Dashboard Light Meaning
The EPC light may come on your dashboard indicating a fault. ‘EPC’ stands for Electronic Power Control and is a system typically used by Volkswagen and their subsidiaries such as Audi, Skoda, SEAT, Porsche etc. If you are driving a VW or one of their subsidiary brands, you may see the EPC dashboard warning light.
Why is the EPC Light On?
There are many vehicle components that utilise the EPC and as such, diagnostic equipment is often required to trace the fault. An indication of the fault may be represented by the addition of other fault lights illuminating simultaneously. Typical faults related to the EPC light coming on are:
- Throttle / accelerator pedal and body
- Brake pedal switch
- Traction control system, part of the stability program (ESC or ESP)
- Cruise control system
- Engine sensor faults
- Low battery charge
- Selecting neutral with ignition on and engine not running to push or tow the car
Should I Drive with the EPC Light On?
Typically, the EPC light often relates to a faulty sensor or switch, but without any noticeable vehicle faults, it’s very difficult to know the cause of the EPC light illuminating. Issues range from a simple faulty sensor, to an issue that may cause further damage is the vehicle is driven for long periods.
It’s advised that immediate action is taken if the EPC light comes on, particularly if you notice a loss of power. ‘Limp mode’ may be triggered by your vehicle to restrict power output. This form of ‘safe mode’ helps to reduce potential damage.
