Were there versions of the VW diesel (early 2000's or so) that needed the intake manifold removed for serious cleaning at fairly low miles (50K or so?)
I have heard about this on a TDI forum. Supposedly is caused by EGR plus PCV residue and folks not driving the car hard enough to keep some airflow in there to keep it clean. My throttle-body had some gunk in it when I changed the timing belt at 90k miles, so I wiped it out. I'll be interested to see what the inside of the intake manif looks like at 180k miles when I do the next belt change, and if needed at that time I'll take it off and get it hot-tanked.
The earlier TDIs also had a shorter timing belt interval, something like 30-60k miles, which would suck. Supposedly with newer belt material you get when you replace the belt on them now, the interval can be 90k like the newer models.

Is the diesel odor completely gone?
The odor is not gone unless you switch to biodiesel. If you're running on straight diesel, the odor will always be there on a cold start (I would think with any diesel), especially in the winter - I only notice it if I start the car when backed into my home garage, or if I have the car door open while starting and wind is blowing the exhaust toward the front of the car.
