VW Polo VIVO EPC problem

Post by netsiandarich »

I have a 2010 Polo vivo 1.6 77kw, I have started experiencing an issue when the vehicle has come to a stop with engine idling (usually at a traffic light or stop street) the EPC fault light comes on. The engine idle becomes rough & increases to about 1200rpm, there is also no response to the accelerator pedal at this time. I have to switch the car off & restart to pull off from the stop. There is no sign of the problem after this action.

The problem is sporadic & doesn't occur at every stop of the vehicle. Prior to this problem I noticed unusual engine response to the accelerator pedal on low revs(in neutral while idling,stationery position) , slow response to react to the pedal & slow return to idle rev mark, sounds like the accelerator is being let of progressively when in fact it has been released completely.

Hi there, i have experienced the same with my 2011 POLO Comfortline, The EPC light came on after driving 11km, first time since I have had the car. I took it to the workshop and after many many tests they still couldn't find the fault. I told them when I stopped the light was off and while they had it, the light never went back on. I then collected my car after they advised that it may be cylinder #2 as it this only had 800kpa of pressure but they could not say for definite that this could be the problem. I drove the car and had no issues. Then two weeks ago i drive the car all week incl the weekend and Monday morning my car would not start at all! Engin was cranking, enough fuel was coming through, battery was fine, then i came to realise it could be one of the sensors. I then had my guy out the computer on the car and found it was the crankshaft sensor. replaced this and she started again with no problem. i did however notice before i started having issues with my car that there is a miss on the idling. There is a a slight miss, now I am thinking it may be the fuel filter inside the tank that may need to be cleaned? As my fuel consumption is also not the same. I used to get 750km out of a full tank (50Lt) now i get 426km per tank. it went from 6.5lt to 11.2lt. I am now testing again what could be the problem as my KM indicator oscillates. At start of trip it will show eg: 100km to go then at end of trip it will show 150km till next fill.
Maybe check the crankshaft sensor, and also your injectors.
Hope this info helps.

Get is scanned.
But 1 of three possible things.
1) throttle pedal error
2) throttle body error
3) air flow meter error.
