I think the ones in the D4s have a larger hole which doesn't block so easily.
Certainly took mine out a while back and that's how it looks and I've never changed it Morris Dancers: Drinkers with A Dance Problem

Mine’s not been looked at for the 50k miles the car’s done. From end of next week she’ll be doing ~7k miles in 3 weeks so was wondering if it was worth cleaning, or whether it’s something I could screw up and lead to issues when I least wanted them.

I had mine out a few months back and it was black similar to the D3’s. Cleaned both the MAP’s and MAF’s with MAF sensor cleaner and has run smooth/well since. MY2012 with 60k.RLD CB Bracket

Just don’t stick anything down the hole which might touch the sensor, this seems to be the biggest problem. I used copious amounts of the MAF sensor cleaner and it worked well with no issues.RLD CB Bracket

Same routine for getting at the MAP sensor as with the D3?

I believe so, remove top engine cover and it’s straight in front of you, ¾ up the engine. Remove, clean, replace and cover back on again. Don’t remember it being anymore difficult than that.RLD CB Bracket

This is the cleaner I used, although there are plenty others.
