What does the epc light mean?
The EPC light system warns drivers by sending codes to the dashboard. The codes indicate the system of the car facing a problem, but not a specific problem in the system. It indicates any faults with the traction control, throttle pedal, cruise control-, and throttle body. It can also show malfunctions and defects of the EPC. An additional sensor can be installed to find what specific problem a Volkswagen is facing when the EPC codes are displayed.It can mean a few things so it may not be good to drive. It can indicate a problem with the mass airflow sensor, throttle body or crank position sensor. The only way to tell is with a scan tool. If it is the maf or throttle body having issues, it is OK to drive. If it is sensing the crank sensor is failing and it goes bad completely, the car won't run.
Had the same problem with the EPC lights on, engine warning light, traction control and no power. Drivable at 15 kph to 20 kph. Had my Jetta towed to the dealership. They reset all the warning lights but they came back right away after I left. They finally replaced the throttle body and it seems to be running great.
