Hey everyone!
Just got my 2001 A6 2.7T Quattro, has about 61k miles on it. The Check Engine light came on and I went to my friend who has the OBD reading equipment and he said that the reason the light came on was Random Cylinder Misfire. I am not losing any sleep yet because the car doesn't shake or do anything out of the ordinary, but if anyone knows that there's something I should tune up or replace, please let me know!

I greatly appreciate any help and any info I have, I'll gladly share with anyone here!
