EPC Light Issues
Available at all e-CAR Workshops
The EPC light (Electronic Power Control) is a warning indicator found in many modern vehicles, particularly Volkswagen, Audi, SEAT, and Škoda models.
EPC Light
What is the "EPC Light"?
When the EPC Light is illuminated, it signals an issue with the engine, throttle system, or other critical electronic component. Ignoring this light can lead to performance issues or even more severe mechanical damage.
Understanding the EPC Light
The EPC light plays a crucial role in modern cars, acting as a warning system for potential issues in the vehicle’s electronic and power systems. Typically, the light illuminates when sensors detect problems such as:
Faulty throttle body. |
Engine misfires. |
Malfunctioning sensors (e.g., ABS or brake light switches). |
Wiring or software glitches. |
At e-CAR workshops across South Africa, we specialize in diagnosing and repairing EPC light-related issues quickly to get you back on the road.
Scan car error codes
The best way to diagnose the issue is by:
- Connecting an OBD-II scanner to the car’s diagnostic port (usually under the dashboard).
- Reading the error codes — these will give you clues about what part is faulty.
Common codes:
- P2122-P2128 — Accelerator pedal position sensor issues
- P0638 — Throttle actuator control
- P0507 — Idle air control system
Common EPC Light fixes
| Throttle body cleaning — If dirt or carbon build-up is affecting the throttle body, clean it with throttle body cleaner. |
| Brake light switch replacement — If your brake lights aren’t working properly, replace the switch. |
| Sensor checks — Inspect the throttle position sensor and accelerator pedal sensor for damage or loose connections. |
| Wiring inspection — Look for frayed or damaged wires connecting to the ECU. |
EPC Light Benefits
While a warning light might seem negative, the EPC light serves an essential purpose by:
- Alerting You to Issues Early: The light prevents minor problems from escalating into costly repairs.
- Ensuring Optimal Performance: Addressing EPC-related problems helps maintain your vehicle’s performance and fuel efficiency.
- Enhancing Safety: Faulty components can compromise safety; the EPC light acts as a safeguard.

Which Cars have the EPC light
The EPC light (Electronic Power Control) is mainly found in vehicles from the Volkswagen Group (VAG). This includes:
- Volkswagen (VW Polo, Golf, Jetta, Passat, Tiguan, etc.)
- Audi (A3, A4, A6, Q5, Q7, etc.)
- SEAT (Leon, Ibiza, etc.)
- Škoda (Octavia, Fabia, Superb, etc.)
- Porsche (some models like the Cayenne, since Porsche is part of the VW Group)
The EPC light is part of their drive-by-wire system, where electronic sensors and actuators control the throttle instead of a traditional cable.
Other brands outside the VAG group typically use similar lights, but they might be labelled as “Check Engine,” “Throttle Control,” or “Traction Control” warnings instead.
