1.2 tsi fr epc light

[CornishSJR]

Hi all, my seat Ibiza 1.2 fr tsi 2013 is causing a slight head scratch. Car throws up the epc light when I started the car so I switched it off and back on again and the light didn’t reappear, had it scanned nothing showing up and now the mpg is around the 20mpg mark where it normal sits around the mid 40’s. It has had the throttle body changed a few months ago, anyone have any ideas? Or is it a case of waiting for the light to reappear and get it scanned. Would it be the turbo actuator? Cheers
