Hard to start and EPC (Eng management) light. But start again and the EPC light disappears!

    General engine management system (EPC) warning light popped up (Audi A4, 1.8T, 2007). Goes like this:


    • Car reluctant to start. Give it a turn for a few seconds. Stop, give it a second turn, she starts
    • EPC light on
    • Car idles at around 1100rpm (normal about 800rpm)
    • Lumpy sounding engine at idle


    If you stop the car and restart (even say immediately after the initial start)

    • EPC light stays off
    • Idles as normal
    • Idles smoothly, as normal


    Any idea what that might be?

    EPC light is not an engine management light. Engine management light is a yellow engine symbol. EPC light says EPC in yellow writing

    EPC light usually points to something electrical, and turning the car on/off almost always solves the issue.

    Engine management light could be anything, and usually won’t go away by jumping restarting the car.

    Just bring the car to a mechanic.
