Unless you’ve experienced an EPC light yourself, you probably have no idea what it is. In a nutshell — it’s a sign your VW needs repair.
The EPC light stands for Electronic Power Control. It’s a warning indicator that there’s a problem with the throttle system of your BMW. This includes the throttle pedal, throttle body, traction control, or cruise control, but can also indicate a problem with other systems as well.
This is typically how it goes down: You’re driving down the highway, not a care in the world, when suddenly the power drops out in your Volkswagen. It’s still driving, but it seems like you need to practically press the pedal to the metal just to maintain speed. And if you should hit a hill — cross your fingers.
Why Your Car is Losing Power
What’s happening is a built-in mechanism has kicked on to protect the engine. This prevents the engine from powering the car over 30. If you are already above that speed when the light engages, you should be able to maintain speed to a certain extent. But if you hit traffic or steep hills, you will have difficulty.

You’ll need to have the car inspected by a mechanic as soon as possible. Depending on how bad your throttle system is, you might be able to temporarily disengage the system by turning the car on and off again when the vehicle is stopped. If the problem is minor, you may be able to drive a week or so before it kicks back on. But the problem will get worse and your car may lose power altogether.
If your throttle system is dirty, your mechanic may be able to clean it to return it to optimal performance. It is very likely the entire throttle system needs replaced, which can run you several hundred dollars.
You should get the car to a repair shop as soon as possible because you may be doing serious damage to your engine.
