The car (UK estate model) has a high pitched whistle that is louder inside than outside. Fuses are ok and there are no error codes. but due to hearing loss I can't narrow down the location. I presume it's a sensor of some kind, but it's not in the handbook or my Haynes manual. Any advice appreciated please.

Hard to really advise without a lot more info but USUALLY whistle you describe would be caused by turbo whistle or air leak , hose / pipe leak but dont think you have a turbo on that version . Could also check the PCV valve / hose , air intake hose
