Have you checked the Idrive for faults?

Is it a Beep or a Squeak? Does it increase in speed with revs ? Could be Water Pump, Alternator, AC pump or a belt tensioner

Hi Dave  Yeah no faults have come up it’s kind of like a beep With a suction it sounds like air  but like a beep I have been checking on the Forum and a few peoples got the same  problems but No one’s got any answers

It’s coming from the left hand side of the engine

Turbo or Vacuum air leak would be top of my check list

The car is running fine How will I  know if it’s the turbo there is no white smoke coming from the car Call drives fine just keeps bleeping

[Macer]

The car drives fine

Clearly if there is a noise that wasn't there before then something is not OK 

But if you are happy that "The car Drives Fine" is all you need then what was your query?

Personally I investigate any strange noises and lubricate/fix them as it is normally cheaper than waiting until whatever it is breaks
