I have had the EPC light come on, on my 1.6 Ambiente (101bhp) a couple of times, with a complete loss of power. I turn the engine off, and back on again, and its fine. Can anyone advise me on what it means? :confused: Many thanks in advance

Electronic Power Control, no throttle cable, all done by electronics and stepper motors.

Could be a pedal or throttle body fault, even a brake light switch.

Fault code check would tell you.

Check the brake lights are working correctly first (and the cruise control if fitted).

Thanks for all of the advice. I have taken the car back to the garage as its under warranty. The first time it happened I had no throttle at all. The second time, the car reduced in power for a few miles, when I stopped the idle was all over the place and it then stalled.

Apprarently there is an electrical fault with the main loom. The garage is sortng it out at the moment. Fingers crossed.

What was the outcome of this mate?

My grans '02 Audi A3 1.6 Auto has had the EPC light come on a few times now while driving. Somedays it's there. others it's not. She reports no symptoms, but I'm a little concerned as she's getting on a bit and is completely clueless!

I won't be able to get down to her to run an error code scan for a week or two, since she lives 240 miles away. And I know the local Audi dealer will rip her off, as they always do.

Should I tell her to keep driving it, due to the lack of symptoms, or make her wait till I can have a look?

Is the problem progressive, i.e. does it start with the light then move on to engine cutting out eventually?

List of suspects (if I'm right in thinking) are: throttle pedal, throttle body, brake light switch, loom connection to ECU......

Cheers.

I have been to the garage many times since posting this! This car (bought back in June) has been a real pain - the worst car I have ever had.

As far as I know the EPC light is to do with the emissions - and yes I still have it coming on, despite having the car in the garage for about a month and a half out of the three months I have owned it! :thumbdwn:

They have just changed the throttle for me - as it the light was still coming on, and it also decided to have a lumpy idle at times, also difficult to start when hot.

I have just done a substaintal trip - Swansea, Cardiff, London, and back here to mid wales, and the light hasn't been on. The car has decided to mis fire at slight throttle, stall twice, fail to start straight away on a number of hot starts, so its far from right. I have asked my garage to get me something else as I have had enough of mine!! :mad:

Hello

I have tried the excact same in my 1.6 2002 Octavia two times now. It seem to happen while driving 85 km/t down a hilltop with the speed pilot on. Have you solved the problem on your car? If yes - I would very much like to know what caused the problem.

Best regards - A hopefull Skoda Owner :-)

Hi I have a 55reg octavia 2.0 fsi my epc light has come on there is no problem with idle or loss of power it's starting to do my head in now it's an intermittent fault it's been to the garage and had a sensor replaced but it still continues to do it any ideas would be much appreciated 

Has it been plugged into a proper vcds? If its only been checked with a generic scanner they dont always show up intermittent faults. A fault scan will point to the correct issue. Honestly theres a dozen + reasons it could be coming on..

This seems to me a common problem with Mk1s. I'm still in two minds whether to spend the £2k having what amounts to a rewire on mine or scrapping an otherwise perfectly good car.

@Gmanibiza18 - Er, isn't a 2.0 fsi an Octavia 2?

 

@Tonyb395 - What makes you think that? The electronics are usually wonderful things, but one faulty component can show up as a dozen or more fault codes, and it needs a competent VAG diagnostician to be able to say "all the other codes are caused by 12345ABC, which is a failed gasgit clump doofer".

You means i scrapped my old cordoba when all it needed was a new Clump Doofer???!! 

Hi all i have the same problem with my mk1 octavia vrs, for example drive down a road have loss of power and the epc light will come on without it cutting out, so ill pull over and re-start it and it goes off, now im having trouble starting it, she would sometimes cut out at a set of lights aswell, i popped to a friends earlier and she really struggled to start with the epc light staying on but the engine management light has came on with so now im really concerned a little help would be very much appriciated, many thanks guys.

Get it plugged in and fault scanned, post up the results and someone might spot the likely culprit.

cheers mate, ill have it plugged in tonight.

Had the car plugged in, found out its both, Camshaft sensor and Crankshaft sensor. 

She's fixed, absoloutly chuffed.

Having only just seen this post I can say the same as Ginge!

Just had the exact same problem on my other vag car (A4 B6 Q) and that the cam sensor needed replacing on that as well, all sorted once replaced.
