04 VW Polo EPC issue

Kealyboy · 20-07-2017 10:07pm #1

Hi today when driving my 04 VW polo the EPC light and engine management light came on the dash. The car started revving up and down by itself and there was also a loss in power when trying to accelerate. This issue lasted awhile but then all of a sudden when I turned the engine off and back on the warning lights went off and car was completely back to normal.

Any ideas what the issue is? And why now is everything ok all of a sudden?

Thanks

Could be something like a coil pack. The fault will come back, so try and get the ECU read for fault codes.

Would that be an expensive fix?

Recently put a lot of money into it for a new catalytic converter and sensor

No, a coil pack is cheap enough, and is often the root cause of catalytic converter failure.

That said. The fault you have could be anything.
