2008 V70III Yet another whining noise problem (with videos)

[bobjet]

I've got the same thing - a whine when the compressor is on in my 2008 XC70. At first I thought if was my transmission and my heart sank, but then I discovered it only whined when the AC was engaged. I was hoping it would not involve an entire compressor replacement, and that I could get away with just an AC clutch and bearing.. Wishful thinking?

Had my Timing belt changed 3 days ago. Noise still there. Definitely goes away when switching off the AC.

Will be going back to mechanic next week for a list of other items to be done. Will let you know what came up.

Years ago my 2004 S80 did the same thing and oil was added to the system and Freon replaced which pretty much quieted the noise. That was several years and about 50K. Also the condenser was cleaned with a.c. coil cleaner which was washed off with a pressure washer. The condenser coils were clogged up with dirt and bug causing high Freon pressure. June

If you kept it under 90 mph those poor June bugs would have a chance to get out of the way...

Well you know how all that effortless power the T6 has effects my naturally heavy lead foot! She doesn't start breathing till 140 and at that speed they go right through . June

Hi OP, Is it possible to un-private the videos in the first few posts? My pump is whining when hot and turning steering wheel. It whines during deceleration from 2nd to 1st gear from abt 20mph to 0.
