EPC light 2009 VW Jetta 2.5 automatic sedan

2009 VW Jetta

We are considering purchasing this 2009 VW Jetta 2.5 with 76000 miles on it. First of all it had the EPC light on the instrument cluster when we got to the dealer. So they said they replaced 1 spark plug & coil pack & the light went out. Does this repair sound appropriate or should we be concerned there could be something more serious wrong with the car?
Thanks Phil

Seems like you should be concerned that there is something more serious going on! I would move on to a different vehicle for sure. Most of all the EPC light has nothing to do with the spark plugs or coil packs. Therefore I would suggest looking at something else unless you are completely in love with it. And the dealer is willing to WARRANTY the vehicle.

EPC Light – Electronic Power Control Warning Light

If a malfunction is recognized in the EPC system, the ECM switches on the the EPC warning light.

For EPC, the throttle valve is not operated by a cable from the accelerator pedal. There is no mechanical connection between the accelerator pedal and the throttle valve. The EPC is a system containing all components that contribute to recognizing, controlling and monitoring the position of the control valve.
