Ok so looking into this fault a bit more now trying to work it all out as have been told by a couple of different garages it will be the aircon pump. Don’t want to throw bits at it for no reason as I have read people saying pump does not fix the issue.
To confirm, my car is a 2015 xc60 D5 AWD. Current mileage 110,000.
This noise started to become evident around 2020 and 80,000 miles (it may have been there from slightly earlier just not noticeable)
Noise is exactly as everyone else says. Changes with engine rpm and stops completely when air con turned off. So we know where it’s coming from.
My next question is, if the problem relates to the above (air con pipe)
Why would the noise start appearing after approx 5 years old and 70,000 - 80,000 miles.
Would this not be evident from much earlier if it was just a pipe that was wrong from build?
