Hi,
Does anybody recognise this noise?
https://youtu.be/h4Zwtg9ZB_o
The dealer has no idea whats causing the noise.
The system is vacumed and filled with 770gr gas.
The noise disapears when te AC is switched off.
What is done/new:
-new idler pulley
-new alternator bearings
-new serpentine belt and pulleys
-new distribution belt, and pump (twice)
-new powersteering pump + fluid
-new engine mounts
-new ac compressor
-new condensor
-new pressure sensor (AC circuit)
-new expansion valve
Everything looks right, hp pressure seems ok, no errors in vida.
Just that noise that is going up/down with the revs.
It seems that the noise enter the cars interior through te presurelines and the evaporator.
The car is a my2009 v70III, 2.4d
Anybody an other idea?
