That being said, the service history on my A6 showed 2 sets of K03s being replaced under warranty and I replaced the 3rd set with K04s when I bought it.
Ironically, my S4 is still on it's original K03s at 90k, so I'm in no rush to put in my K04s. And yes, I'm chipped and I drive her pretty hard. I just take really good care of her and warm up and idle down, too.
