Hi. I have a skoda octavia 2003, 1.4 16 V. yesterday I was cheching some fuses.next time when I've started the car the TESTING ENGINE ELECTRONICS light came on. I took out some fuses and put them back and since then, the yellow warning light (oil) is flashing 3 times and goes off when I start the car and the EPC light stays on while driving.
Do you have any suggestions?

. Check all under hood and under dash fuses with a test light or multimeter.

. Check for codes.
