What causes epc light to come on?
All drive-by-wire cars (starting from 1995-2013) has an EPC light. EPC stands for Electronic Power Control which is controlled by the ECU (Engine Control Unit). This is a computerized hardware device with software to control all sub modules in the car that is connected by either an OBD II (on-board Diagnostics II) or Can Bus (Controller Area Network). Any input from these sub modules on the drive-train can activate the EPC circuit especially if the reason for sending its signals to the ECU, could cause damage to the engine. For example, if the car runs out of oil, or if the emissions exceed the prescribed level ect.... the sensor will send a signal to the ECU which will activate EPC circuit, cut power to the engine (limp mode). Limp mode signifies there is a problem and should be investigated. If not fixed, the EPC can ause the engine not to start unless corrective action is taken.

2000 vw jetta vr6 EPC light goes on and off while driving what are possible causes or solutions to this problem?
What causes the EPC warning light to come on occasionally on your 2001 Volkswagen Jetta 4 cylinder gas?
The EPC light came on today on a 2001 Seat Ibiza, along with the car's lock suddenly locking. After 3 or 4 efforts, we figured that the problem was solved unlocking the car using the key while the engine was on (the electronics on the car always blocked when the EPC came on). After that the EPC light switched off. I hope you can solve the problem this way.
If the EPC light came on in a Polo and there is smoke coming out of the engine, there is a problem with an electrical circuit somewhere. EPC stands for Electronic Power Control. Perhaps an electronic sensor on the motor shorted out. It is also possible that the entire fuse panel inside the engine compartment has shorted out.
The epc alarm on a VW Jetta is the electronic power control. When this light comes on it is to warn you of some sort of problem with the accelerator pedal control. This can come on because there is a serious problem or just because of a bad sensor, the best thing to do is to have a diagnostic test done to make sure there is nothing seriously wrong.
