EPC - Electronic Power Control (i.e. Engine Management system) fault. Means there is most probably something wrong with a sensor signal. Could be the brake light switch as mentioned above. When fault is fixed the light will go out.
When I had the beetle i had the exact same problem, the EPC isn't mentioned in any great detail in the manual either.
Its the brake light switch, I made them collect the car and tow it away under warrenty as I wasn't prepared to drive with no brake lights.
Fault codes read is the best way forward to point you in the right direction, but have you looked at the battery voltage with the engine running. It may be that voltage is too high / low, or maybe the battery is on the way out and the alternator can't cope with the steering load.
I have the same problem.
after running the engine for some minutes the light is on and remains on if i stop and restart the engine.
the light is off only if i stop the engine for enough time but it lights again some minutes after i start the engine. Sometimes it lights off if i run the car to a motorway but i dont know if this is related to the problem.
What thepink fluffy dice is going on?
yeah mate...my polo 9n has tons of warning light flashing...just like a damn x'mas tree..
powr steering lights, air bag lights...who know wat light will come on next..
long story short....dodgy wire loom connection causes no elec goin to the dash gauages..eventually couldn't start the car....which happened on new years eve of last year...having friends trying to jump start and nothing happened...after some desperate attemp..i tapped the dash with my finger tip...and damn...lights back on and engine start...
..one day i sniff under the steering wheels where the wire looms are...and its the alarm guy who did a dodgy wiring job that cause everything...
been to the main dealer all they telling me is ..no fault showing on the computer and car running good while in here...only suggestion is to replace the whole instrument cluster...400 euro..
hope this time the EPC light is just cause by bad wiring again...any good tips as how to solve this mystery would be great
hiya i have an x reg polo, have had THREE new gear boxes, new clutch, new suspension, new pretty much everything now the ABS warning light randomly flashes n most recently the EPS warning light, is it jinxed?!
I have read several items that indicate that the brake pedal s/w can be the cause of the epc light to display.
I have a 2000 x-reg 16v 1.4 Polo estate and there are indeed TWO switches on the pedal.
One is white with two electrical connections and this operates the brake lights - It is sometimes called Switch E.
The other is blue - sometimes called switch F - it looks like a switch, but it is technically called a valve! It also has two wire connections. This switch, or valve is connected to the Engine Control Unit (ecu) and acts as a fuel cut-off device when the car is braking - obviously, the ecu does not want to needlessly pump fuel into the engine when the car is under brake - so if it operates properly slightly improves MPG, particularly if one is doing a lot of stops and starts. From my experience, even with the switch/valve removed,the car will drive normally (although the epc remains on) and some fuel may be lost at the points of braking.
Either, or both switches can be removed, although a little ackward, by kneeling outside the driver's and looking up the pedal stems (after removing any easily removed covering). You will obviously need a torch. Remeber, the white s/w for the brake lights - the blue s/w (valve) for the braking fuel cut-off device.
If you need to replace, try a parts specialist, often much cheaper than a Vw dealership.

Hi there guys. This has just started recently on my wife's 2000 Polo as well and hte brake lights are not working. I know there are 3 fuses on top of the battery. Would one of these be the offending fuse or is the main fuse box located elsewhere, like under the steering wheel?
Hi, On my 2001 Polo 1.4 16v auto, I have had over a year of the Engine Fault and EPC light intermittently coming on (either one or both) and the garage unable to cure the problem - until - they noticed a small split in the brake vacuum hose from the brake servo. (cost £24.50) We think this was leaking with slight engine movement. We now have had one whole glorious week of no fault lights showing!
Hi, I have an 04 plate 1.2 polo and epc light comes on when I stop at traffic lights and goes into safety mode where I can only go 15mph max with the car revving without me pressing the accelerator unless I keep low revs on. I have taken it to a garage which told me it was throttle body, so then we had a second hand one to replace it. The light still comes on and the garage are unable to fix it? Can anyone help with this problem?
