SOURCE: I have a VW mk4 2002 1.6 Estate . The EPC light

You will need to have a suitable diagnostic tester plugged in to read the fault that has been logged. Air mass (or air flow) meters are a fairly common thing that can go wrong.

SOURCE: a sleeved covering 4 wires has been cut under the

Generic OBD Test Code P1545 (VW- V.A.G 1551 scan tool scanner code: 17953) "Throttle Position Control Malfunction"

Yes, it is possible that the cut wires could be the problem with your "epc" light and lack of power. If the cut wires are the wires going to your throttle body position sensors, I would say that it is DEFINITELY the problem, as well as the cause of the code you are receiving. If they are not the wires leading to the throttle body, then I don't know what to tell you about the wires unless you can tell me what they go to.

At any rate, you have a problem with your throttle body control circuits that will most likely have to be verified (diagnosed AND verified for proper operation after repair.) with a VolksWagen V.A.G. 1551 scanner.
Please note that generic OBD scan tools cannot perform the functions necessary to verify the repair or to reprogram the throttle body with the Powertrain Control Module for proper operation.
The manufacturer states that it is "absolutely necessary to adapt the [Throttle valve control module] to the PCM ".

SOURCE: car bogs down epc light

epc is short for electronic pedal control, the throttle is controlled by an electric motor and has two angle sensors in the throttle body. the pedal it self has two sensors as well, sometimes after a battery replacement or replacement of certain parts (ecm throttle body pedal controls) the control modules need to be reset or "relearned" to one another. the dealer or independent shop with correct softwear can do this, if problem persists possible bad throttle body pedal sensors or ecm (engine control module)

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.

Vw golf lost all power and EPC LIGHT came on,started again after 10mins,but car feels like it pulling????

The EPC light normally comes on for electrical throttle issues. Either the gas pedal inside the car that fails or the motor actuator that fails on the throttle body causing the butterfly valve not to operate.

EPC = Engine Power Control it's the engine control module yellow warning light.
You need access and erase the EPC memory by DTC (Diagnostic Trouble Codes) using diagnostic equipment connected to the data link connector of the car, in order to reset the EPC, and turn off the EPC yellow light.

My EPC light goes on and then it is on it is very hard to get my car to start. when i am able to start the car my check engine light is on continuously. My car also seems to be accelerating by it self...

Multiple causes for EPC light (Electronic Power Control).
Vehicle needs to be scaned with appropriate diagnostic tool , without it nobody can tell what's wrong.
You'll have to take it to work shop for diagnostics.

The ingnition won`t start, how dow I by pass the EPC and start, the car was running fine but started not switching, when turning the key nothing happens, what is the EPC for? and how do I fix it with out...

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.
