Take it to the dealer, the EPC warning light - and even more the failsafe run which doesn't allow you drive faster than 20mph) is an indication of serious motor troubles. They can read the ECU faultcodes, which should be a good startingpoint for troubleshooting the cause ...
You could do some basic troubleshooting like checking the air filter, the oil level, the spark plugs, etc. You didn't fill it up with bad gas, did you ? And does the engine make strange noises/vibration when running idle ? In case you fixed some obvious cause, you can dis- and reconnect the battery to erase the engine's faultcode. If it's not fixed, the EPC (and failsafe run) will simply come on again.
My advice would be not to drive it untill it's fixed to prevent more potential damage.
SOURCE: epc light just came on 2003 jetta, what is epc?
Electronic Power Control. It controls the power to the wheels to keep them from skidding by keeping them at the same speed. It works best in the snow/ice/and mud. It gives the driver more control of the car in extreme situations. ABS keep you from skidding in a stop, and EPC keeps you from skidding under acceleration.
The car will drive like a normal car with out it. The problem can be found by using a VAG scan tool. It could be a wheel sensor, or the module.
Good Luck!
