I'm probably going to look a right lemon when/if it gets found its probably nowhere near vacuum pump, ha, Ha.

Know how you feel... I have had an issue for 4 years after an oil change (what I presume, coincidental). Once the car gets to normal temperature, if feels slightly sluggish. Change a few sensors, cleaned EGR, replaced MAF, changed turbo vacuum control, turbo checked out 100% all on advice of a few good people and of course no codes are being thrown. A few BMW mechanics have stated they do notice the change in the performance, that there is definitely an issue but since no codes are thrown it would be a long process (and expensive) to locate the issue and to just wait until it gets worse. 4 years down the track, its not getting worse, but the issue is still there
Anyway, I hope you get yours sorted soon.. At least you have a noise to track down
