As the title states.
Post up your issues.
My RS came with the exhaust rattle issue that a few other have had- It has been fixed by way of replacement of the muffler. It was bad on cold startups but also loose sounding while driving around in anything other than sport mode at times.
I also had a CEL- This lead to a PCV valve replacement.
Car has 5500k on it and there's another CEL....... who knows what it is this time. No loss of power or rough idle so I'm not overly worried. Update when I get one.
Edit: The CEL went away... I did a few good launches and opened it up harder than I had in a while and it simply went away. I expect when I go for service they will let me know what the light was for but it was on for about 4 days and has been off for about 4 now as well.
