Vac operated component
Hi there, can anyone identify the component in this video that is making that chattering noise? Its caused by the valve on the vac pump failing and not pulling enough vac to hold this part open or closed which ever it is. I've had the valve changed and it no longer chatters when idling but still does when throttling off once engine has reached operating temp. I'm wondering if this part needs changing also but I have no idea what it is or what it does.
Its on a XC60 2011 D5 215hp auto awd. Can anyone help?? https://www.youtube.com/watch?v=OHD8WR_Ec8o |

I think you may find that the noise is caused by a lack of vacuum due to front and rear engine mountings being shot. Do you have the pop-pop-pop when you loosen the oil filler cap?
The vac pipes from the engine mountings run to a valve/splitter which I think also controls the wastegate valve on the turbo. Should be close to the airbox I think. non-vacuum mounts are listed in the parts catalogues so perhaps you could terminate the pipes and get your vacuum back. There is a video on youtube under vacuum mounts I think. Hope that may help. |
