If you do this, please post details (experience, where you got it done, cost, results). I'm curious because it is generally accepted that this is more necessary (or needed more frequently) on N54 than N55, so I am curious to see how bad it looks in there compared to the pics I've seen of N54's before.

I saw a 2014 335 last week (n55 with just over 50k miles)...the valves were spotless.
I think the recommendation is 100k miles on the n55...vs every 40k on the n54.
