The whole time the car was driving fine.. no problems what so ever. i pulled up at a gas station pumped gas and when i started my car again the epc light came on and i noticed higher accelaration then normal :|.. i read the solution at the bottom which seems sensible but it would be great if you could tell me bout to increase in speed ?

I wnet out of gas on my VW Beetle 2001 last saturday. When I added gas to the tank, the car wouldn't start and the EPC light went on and I haven't been able to get it to start ever since. Would the EPC light have anything to do with the gas pump or anything related to running out of gas?
hello : my proplem is began after i drive my passat 5 kilometer the EPC yellow light is appear and i dont know what that mean . thanks foer your help .. my passat 2003 model petrol . 2000 cc . Rami Safran PALESTINE
the belt slips, and the engine goes into limp mode, and the epc light will come on- to protect itslef until its fixed. Once its fixed...you may have to decode her up to 9 times to get it to start...I did. Ive done 5 timing belt changes on these blasted cars and every time it slips a tooth and the engine cuts itself off with epc, i have to decode it at least 8 times. good luck. and to the idiot who said gas cap..get a life .
The EPC light means the car is running in "Limp Mode". I had the same thing happen to my car (2001.5 Passat GLS) and i chased the problem for three months.... I would drive and begin to get on the interstate only to have complete loss of power and inability to accelerate. Id pull over, turn off the car then crank it right back up and it was fine. But it came back again randomly. I would suggest pulling codes with a scanner. If you do not have one most local auto parts stores will scan them for free.
Mine turned out to be a sensor that is right on top of the engine in the front.... If I'm not mistaken it's the engine speed sensor, also called crank sensor or impulse sensor.
You may also want to do a throttle body cleaning.... That would be beneficial no matter what.use extreme care when doing any TB stuff, though, as it's very sensitive. I doubt you want to be forced to get a new one for ~650$.
I'd also suggest getting the Bentley Manual for the car as its VERY handy!

EPC refers to the drive by wire system. This system, generally speaking, encompasses the throttle pedal and its position sensors (it needs to know where your gassin' foot is) and the throttle body.
Most likely, the EPC light and its associated faults for this scenario are a symptom, not the problem. Meaning the actual root cause is causing the no-start/no crank issue AND fault codes related to the EPC system.
And the most likely root cause is an ignition switch, NOT the engine speed sensor.
With a bad engine speed sensor, the car will still crank all damn day (or until the battery dies) but the car won't start.
If you get a no-crank issue, and then it eventually starts either with or without an EPC light, again, the most likely problem is the ignition switch. Not the starter, not the battery (though the battery proper and the cable connections must be perfection itself to rule them out.) You can get these issues with a visually perfect but still faulty battery connection.
Your EPC stands for "Electronic Power Control" and without it (bypassing it, as you stated), you will not be going anywhere in your car. The car MUST have the EPC on/enabled to run, as I have been told. The VW Passat does not have a throttle cable... it is controlled electronically. The EPC light means something is wrong in the drive-by-wire path, the
"gas pedal" potentiometers or the electric motor-controlled throttle
body, etc. You will need to take it to a mechanic/repair shop that is knowledgable in foreign automobiles (especially VW's) and has the appropriate tools and equipment to read any "codes" being kicked out by the computer.
I have a 2001 New Passat with the EPC light coming on randomly and it will idle high but next time I start the car it goes away. I think you will have to take it in to the dealer.
I have a 2002 Passat, 1.8L Turbo. I had a problem where my EPC light kept coming on, and I would have a lot of trouble starting my car in hot weather. The EPC light stands for Electronic Pedal Control. When you press on the gas/brake, the pedal doesn't pull a wire like in the past, it's all done by computers. The sensor is saying that somewhere along the path from the pedal, to the brake that something is acting up.
I took my car into the VW dealer nearby and they said the sensor was going bad, and that's why the light was coming on. They informed me that once the sensor went bad, my car would stall, and likely not start again until replaced. I decided to have it replaced (about $250), and I haven't had a problem since.
