Just started to notice a whistle like noice at idle on the T6. Dissapears on acceleration but is there as soon as you take foot of accelerator. No obvious signs of air / vaccum leaks, performance is ok. I did think maybe PCV firetrap/ pipework but removing filler cap makes no diffrence. Also its intermitent so is confusing if it is a leak. Any ideas anyone, its driving me mad.

At idle....sounds like its more of a sqeal than a whistle. You sure its not you AUX belt slipping? Spray a little bit of WD on the belt at idle just to eliminate the belt. Could save you a lot of stress. Other than that, can't help you. Impossible to say without seeing the car in the flesh.
