Hey all, I'm driving an i30 Style 2012 1.4 Petrol and I've been investigating a strange issue with my engine light turning on and off by itself (error P0011) and started investigating timing-related things. I pulled these Timing Advancement graphs from the scanner while the car was idle and the engine light was off.



It jumps between ~12 - ~22 degrees with some randomness in between here and there. I was shocked to see how erratic and inconsistent it was. Nothing seems to feel wrong, but is this what timing advancement is supposed to look like? Or is it possible that this is either a faulty sensor or even a faulty scanner?

Any insight on what "good" timing advancement is supposed to look like would be greatly appreciated
