My vehicle listed above is a Diesel. It has had this intermittent issue for a few years but is getting more common and I can almost predict when it will happen.
The fault sensation and sound from the engine is a fup, fup, fup, and it seems to happen after coasting up to a corner and when accelerating out at medium load probably in 2nd gear. I’ve seen on my OBD app that the MAP, MAF and fuel rail pressure all fluctuate, more so the MAF reading though during hesitation.
Any ideas?

Are there any trouble codes? Also, when this happens do you see white smoke coming from the exhaust pipe? I kind of sounds like the turbo waste gate is getting hung up. But to be sure can you take a short video of the noise and upload it here so I can see what's going on?
