Is my X5 4.4 a N62 or M62?

[cgy_X5]

Hi everyone, usually I have been able to find all of my answers through the search function but have been unable to find the necessary information for this post. Long story short, my indy mechanic believes I have a M62 engine and I thought I had a N62. I need the PCV (CCV) replaced due to cold weather issues and as it has been noted in other threads the difference in work between the two is substantial.

I have entered the VIN into a few decoders and have only come up with: 4.4L V8 FI DOHC 32V.

Any help is greatly appreciated and I apologize if this thread already exists and I was just unable to locate it.
