991.2 gts whirring noise

[Busa mav]

Just back from an 8 week 5800 mile road trip.
Early on I noticed a whirring noise, particularly on start up , only when it s in gear and starting to pull away or slow.
Finally back home and booked in to main dealer.
Got the video of the health check and there was a quite bad dripping water pump .
All replaced under warranty, £2300 inc 7 hours labour .

Collected my sparkling clean car this morning.
Cold start , the noise is still there, straight back in , the mechanic comes out to listen and there it is again, crystal clear .

Thinks it s probably the vacuum pump , so goes inside , checks with the mannager and he agrees, despite not coming out to listen . “ It s a very cold morning and the pump is working hard , to be honest , as expected “
I ve owned the car over 4 years and never heard it before.
Drive home, car now warm and it s still there .
I email to confirm the problem and that the water pump must have been a distraction and asking what happens next .

Reply confirms they won t investigate acoustics , if the pump throws a dash light then they will look !
Any other thoughts on what it may be or how to proceed?
I think I should just book it in and cover the investigation costs as I first did.

When I had issues with my local OPC s inability to fix my 911, I spoke to Porsche uk. That seemed to help.
They will try to fob you off & ‘they all do that sir’ is a common line.
