The EPC light came on in our vw golf 2001. It now takes three or more tries to start the vehicle. When driving after stopping at a light or stop sign the car dies and the battery light, epc light and check engine light all are lit. We have had problems in the past with it not starting in the rain either. My husband has changed the speed sensor, fuel filter, spark plugs and wires, and has checked that all fuses are operational. Please help!
Tell him to clean the electrical connector at the throttle body with 90% rubbing alcohol. He may want to use a nylon brush on the contact pins while cleaning. I'm pretty sure the car needs a throttle adaptation performed also. Find a shop with a Vag Com scanner, they can do it for you.

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 .
It sounds as if your vehicle may have severe water damage to the engine. The engine sensors on the golf are suseptable to water damage and can result in epc light that you are seeing on your dash, or so i was told by VW. I replaced all the sensors, alternator and the computer on my original engine, but this action didnt fix the problem. So i bit the bullet and replaced the engine, and haven't had a problem since. If you do the labor yourself it can be done as cheap as $4000. I hope this helps mate.
Code points to "Cruise/Brake Switch (A) Circ Malfunction" which means the switch or connections might be bad. Most VW's of this era had a recall on brake switch, check with dealer to see if your car had it replaced. Stop lights might be out, cruise not working. Replace switch if any of these conditions present.
The EPC (Electronic Pedal Control) is the "fly by wire" system that
controls the throttle, it took the place of the cable that went from the
gas pedal to the throttle body on VW. If this light is on and there is
also a P0102, MAF (Mass Air Flow) related code stored in the vehicle's
computer, the EPC may be caused indirectly from a faulty MAF. If the
EPC is on and there is no other codes stored, it could be a faulty
electronic throttle body or need to be re-programmed. The vehicle's
computer must recognoze the throttle body so when replacing it with new
or used it will need to be programmed at the dealer. Recently I replaced
a MAF (a common problem on VW's) on a VW Golf and when I cleared the
code the EPC went off as well.
EPC stands for Electronic Pedal Control. The vehicle may have detected a fault in the drive by wire system and shut the vehicle down. You will need a scantool, not a code reader, capable of communicating with your Volkswagen. Once you know what codes are present you'll have a lot better idea of what is going on.
It is a wiring fault, but they are looking on the wrong end. You will need to have a VW dealer "repin" the electrical connector at the throttle body. What this means is, the dealer will take apart the connector, cut off the old pins and crimp on new ones and reassemble the connector. This is a common problem on drive by wire VW's. The dealer has a bulletin on the problem and I don't know why they missed it. They will probably have to order the connector kit however. Good luck!
the epc light is telling you that you have a feuling problem, get a mechanic to run a diagnostic scan to find the suorce, it should be only something small because the only dangerous light to look for is the oil light
I doubt it's the fuse. A very common problem is the brake switch on your brake pedal goes bad. This causes the EPC light and no brake lights. This switch was recalled by VW in 2007. Here is the story from USA Today http://www.usatoday.com/money/autos/2007-02-26-volkswagen-recall_x.htm Your VW dealer will replace this switch free...
