Check Engine light
Hey guys, have a quick question. Had some work done to my 2013 grand sport A6 about a month ago and had a check engine light come on. Initially it went away when I restarted the car, but it came back a few days later after I romped down on it pretty good and now wont go away. It has a cam kit,1 7/8 long tubes with high flow cats, corsa cai and a tune. The code that was read was P0300 "random misfire detected". Any ideas what it could be?
