I have a 2001 vw passat gls and I am currently paying out all types of money to get this car fixed. I drove my car home from the dealership from just putting in a new throttle body,gaskets, and valves. When I go outside to crank my car, I check my headlights, then the epc light came on and the car started to idle up and down. Then the anti-slip regulation light came on. So when I started to drive the car it start to lose power,then the check engine light came on. So the only thing I could do was put the car in reverse and park it. Later I went back outside to start the car, it didn't do any of the things it did before, the only light that was on was the check engine light. So, I had someone to follow me to the dealership where I left it. And they tell me that can't see why the epc light and anti-slip regulation light came on, because it is not showing now. Please help what is wrong with my car?

run the fault codes
indications are injector problems either wiring , or blockage
check fuel pressure as it could also be from low fuel pressure , problem pressure regulator , blocked filter or EVAP venting problem
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 .
You have an engine code for something. Take it into a local parts store and most of them will scan for free... otherwise look online or on ebay and you can find scanners for cheap. VW's get a lot of lights it seems because everything is really regulated.
First of all you need to access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the ECM. Then the EPC (Electronic Pedal Control) yellow light will turn OFF.
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 note that you posted your question 14 Feb 09, so happy belated Valentine's Day! Anyway, I own a 2004 VW Passat 1.8 and am currently facing the same problem (EPC light and check engine light on) and subsequently, I coded it out, which was P0322. I took my other vehicle (more reliable) into the VW dealership in Olympia Washington. I was going to replace the EPC sensor, which typically handles what is sent to the car's brain, telling it how much gas it needs to run. However, the technicians at the dealership told me to code it out before investing any money without knowing exactly what should be replaced.
I took the code and determined the "crank sensor" was defective. If you call around, you should be quoted anywhere between $48 and $90 respectfully. If your VW was lurching like it was missing for a split second at a usual speed, or died at stops, then I would say you were experiencing the same problem I was having. Hopefully, this will fix your problem? The part is pretty inexpensive, but I think what VW charges to replace the sensor, is highway robbery. Anyone in your family mechanically inclined? Good luck!
