Suspension: Top middle engine mount aluminium box on the side of bracket

[Rex7]

Hi All can any one help with my above request when you take the middle top bar off the engine mount, the bar runs from left near the suspension strut bolts to the same on the right hand side it has a small aluminium box on the left hand side as you look at the back of the engine not sure what its for.the Volvo mounting that the bracket fits on to is 30776354 and the brackets fit either side,

Have run x2 V70 with engine mount 30776354 and have replaced these mounts on both cars. I have no memory of the aluminium box you show. Can you take a wider angle image showing more engine? At the moment I'm baffled by your current image.
Cheers
Bob.

Are there any wires going to it

What model / year is the car

Possibly some sort of vibration sensor / crash detection sensor or something would be my initial gut reaction but having never seen it before that's a total shot in the dark

Looks like engine vibration damper part number 30741762 (I think)

i to think its a vibration damper there is also one in the tail gate and one under the car behind the engine its possible there are more but iv not found them

Hi Bob it is fastened to the middle mounting on the bar that goes across the engine will try and do a better picture tomorrow cheers

Stuart it is S80 D5 diesel engine 2004

well that's a new one on me, I thought the whole point of the rubber bush was to dampen vibrations so how does that thing work? just pure curiosity really

[V70roma]

From the parts listing it seems to indicate it's a damper but I'm also curious how. Possible theory so far it's purely an harmonic mass damper with the aluminium casting housing a denser material beneath the four bolts may be lead? depleted uranium? Be interesting to know what's beneath the four bolts.
