02 jetta 1.8t my epc light came on around a month ago and about 2-3 times a week my car started shifting crazy from 2nd to 3rd and you had to get the rpm high before it would change, then the car would take 5 min to start some days, then a week ago it took me 30 min to get it started and i had to pump the gas to get it to start. then yesterday it wouldnt start again and i still cant get it to start. it acted like it was flooding so i checked the plugs and they smelled of raw gas and were wet. so i let it air out for a few hrs. changed the plugs and turned it over and still nothing. if you pump the gas it tries to start but spits and sputters, but if you dont pump the gas it justs turns over
Need the right software to diagnose the fault ,,,,sorry best advice here is dealer only

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 on, What does this mean?
EPC stands for Electronic Power Control and it means that there is something wrong with your cars electronic systems (in your case most likely the electronic engine controls). This could be a serious problem with one of your cars systems or could be as simple as bad wiring (especially if your car has any added after-market components,I would go to any Kragen auto or a chain parts store like them and they will run a trouble code test of the cars electronics, post the code on this thread so if I or another expert reads it he will have all the original information.
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!
SOURCE: 2005 Jetta has no power. EPC and many opther
Electronic Power Control take readings from a dozen different sensor, and sends out just as many operations. If you invest $50 in a VAG scan tool, you will find all your problems listed for you on a nice display. It plugs into the cars computer under the steering wheel. You will not damage anything, it can only read and clear codes, and do some tests. It will take all the guess work out. Then post the codes here for help on fixing them. It could be you need a new ignition coil, for instance, which you can get for around $100 if you shop smart, and on-line. An auto store would charge $350. So, get the scanner....and then we can get the car running.
Good Luck!
