UK-POLOS.NET - THE VW Polo Forum

Hi folks,

Hope everyone is well.

Was heading to the gym earlier and about 5 mins into the drive (just about to merge onto the motorway) and the EPC warning light was on the dashboard. Noticed straight away I could hardly put my foot down to accelerate. Car didn't feel right, maybe limp mode?

Turned around and went home as didn't want to be stuck at the gym.

Engine off and on when back home and the warning has gone. Worried there is an issue somewhere, is it worth me picking up my own diagnostic kit or book it in with VW? Anyone else had the same issue with 2019 GTI+ (approx 45,000 miles).

Cheers.

Hi mate,

Sorry to read of your problems. If you try an internet search on ‘epc warning light’, the AI response lists the common causes. I’d expect fault codes to be stored so if you were to get a diagnostic kit, you could at least read the fault codes and do an internet search on the codes to establish what the fault is.

In your position, I’d probably go to an independent VW specialist to get the issue fixed if there’s a good one near you, rather than go to a VW dealer.

Good luck in getting it sorted. Please provide an update once you know what problem is and it’s been fixed.

Thanks mate, hope all is well on your end!

Very lucky to have a family member who can take the car in for me and run a diagnostic test. Hopefully over the weekend can get some answers and fingers crossed for nothing serious, no other signs of the car acting up.

Will post an update.

It could be due to carbon build up on the ports - happens to me every 50 000KM's or so and also brings up the EPC light and puts the car in limp mode. I can generally feel it coming on because the car "misfires" and acceleration is non existent. Hope you get it resolved without much fuss all the same.

Thanks for the reply OomStu_ZA. Is that much hassle in terms of fixing?

I take my vehicle to the VW dealership because I have a very long extended motor plan. Here is a YT clip that may help (at 4min he explains how to clean the valves):

Thanks mate

Evening all,

Quick update, plugged the diagnostic kit and had the following error codes:

B200FF0
U112100
P24530
P26F800
P16D400
P030000
P030400
P060C00

Been advised to change the Ignition Coil Pack and/or Spark Plugs. Hopefully that will do the trick.

Cleared the codes so once the work has been done will have to test and fingers crossed no more error codes.

I had similar symptoms and epc light in the new year. The garage said carbon contamination and needed a walnut blasting and new plugs. The misfire was still there after they did that, replacing the coil packs fixed it.
My error codes were P030000 (random misfire), P030400 (cyl 4 misfire), P036300 (misfire detected fuelling disabled).

Good to know you guys also suffer carbon build up, I thought it maybe due to the RON95 unleaded fuel we have here in South Africa since you guys use 98 there right? I recall SRGTD said a while back carbon buildup wasn't a problem in the UK anymore.

You may have been thinking of my post in the discussion topic at the link below (the 6th post from the top) ;

Hi all,

Just a quick update. 4 new coil packs and 4 new spark plugs later and all seems to be okay. Car definitely feels a bit more responsive as well.

Good to hear it’s been sorted .
