I have a 2005 VW Passatt and the EPC light came on in the vehicle any idea as to what this is

I would stop using the car

With VW/Audi there may be shops that work
on them, but you need scan tools specific to
that make

Non of my domestic or asian venders even offer that

So your best bet is a VW Dealer, so they can scan the vehicle
for the problem

When the powertrain features effect the transmission, you can
ruin a trans in ten miles of driving So Don't Use It like that

You can Google EPC which I did, but I can not spend a long
time to learn Euro Technology & the fix, when I don't see those
vehicles

We have a friend that has a VW & last Nov 2013 the car spent
5 weeks at a dealer, they had to contact Germany, as they had no
idea how to program an ABS Module,all because a switch that was on the outside for a decade & replaced by the vehicle owners,
was no inside & your done

In the British Isles & other parts of Europe, they take that in stride
& don't get up set or have the issues we have in North America

EPC means Electronic Power Control.

When this light comes on, yopu could have such a sudden power loss.

However, before visiting a workshop for help, do the following basic checks:

No air leak into the intake system.

Ensure that all the electrical socket in the engine management system are well fitted, no loose contacts.

This light can be caused throttle valve malfunction, MAF, brake lights, EVAP , 02 sensor, secondary air pump.

I suggest you visit a competent dealer or independent shop for help. They will scan the EPC and run 'Throttle Body Adaption'. and diagnos the problem. Ask for a garage with a 'Ross Tech VAG-COM' or a ' VW diagnostics scanner.'

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.

Hi,
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 the Electronic pedal control. The mass air meter, brake switch, the throttle body, the gas pedal, wiring, and the computer all are tied to the EPC light. If you had a EPC or the engine light on then there is a fault. This can cause the computer to enter a limp mode or the improper signal is sent from the accelerator which manifests itself as poor performance. There have been some recalls on this so I would visit your local VW dealer.

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.

Check the engine codes, and replace or repair the faulty sensor (most likely the MAF sensor).

Thanks for using FixYa - a FixYa rating is appreciated!!

It sound as it your oil pressure senser or the oil pump needs replacing.

EPC could be Engine Power Control
