Very nice. You're going to love it!

One thought that has crossed my brain as well is that there are only a handful of individuals reporting the issue (its not like the n54's HPFP problem), but it is certainly enough to get my attention. I'd be curious to know how many diesel owners there are on our forums and what percentage has reported the problem. One thing to keep in mind though is that no one is going to post a copy of their non-anonymous work tickets showing 10k in repairs covered under warranty then say in the same thread , "I've been running a tune for x miles". I think most are a bit too paranoid for that (I would be). That said, I haven't seen any evidence of a correlation between tune and carbon either (not to say there isn't one).
