Yes, I had it done under CPO. The N63 is notorious for bad valve stem seals...among other things. The stealership will probably charge you $8,000+ to do the job. Find an independent shop that either already has or is willing to rent the N63 Valve Stem Seal Tool Kit. The kit enables replacement of the valve stem seals with the expensive labor of removing the engine. You'll probably still have to pay a few thousand.
