My Ride: -04 530D
You can find more information of that flap with search.
But shortly: It's underpressure operated "silencing aid". Low rpm it's closed to minimise out coming sound. Higher rpm's it opens to minimise back pressure to the engine.

I don't believe that we can get rid off that tact completey ever. Pressure rise in cylinder is that quick and pressures over all are higher than in petrol engine.
Exhaust voise is different than mine (530d) because I don't have particle filter and that way little different system.

When my car was on the rolling road and it was beated to the max, voice was like small gas turbine. That's of course back of the car. That 535d video sound more like soft v8 sound. From the front I think 530d and 535d are same.
Cars should be next to each other to make any real comparison.
