I wasn't aware that u need to program the ecm once u replace a battery. 2012 S5 V8. All of my warning and dash lights sometimes flicker on and off but it starts everytime and runs almost perfect. I do have some blueish smoke coming from my exaughst so there is the obvious burning oil. No leaking on the ground but the valve covers were pretty caked in oil. Can someone tell me what these connectors are? The passenger side is full of oil. Any other thoughts or suggestions would be greatly appreciated.
