My Milltek back-box is mounted a little on the high side. (Reallty couldn't be a75ed to take it off again)
It rattles sometimes at low revs, over occasional bumps and sometimes when I close the boot.

It will more than likely be the exhaust rattling against it. Remember the exhaust will move with the engine as it varies revs.

I had a fault in the valve on the wastegate. I don't think it's the same as the symptons sound slightly different These are the symptons I had and so should eliminate the fault I had:

It was easiest to test while coasting downhill, at fairly low revs so no on boost I guess, in gear but foot off all pedals, so engine braking and a rattle. VW replaced the turbo under warranty.

I have a vibration/grinding noise that is most noticeable in similar circumstances as you mention above. I have noticed no difference in the cars performance what so ever but the noise is driving me mad. Someone mentioned that is could be types (Pirelli p zero's) as they are close ish to the tread bars and apparently this is a known issue but I have heard nothing about this. I'm hoping this is not a turbo problem- how long do Vw cover these items as I have an 07 ed 30 with 51k.

Can anyone offer any suggestions?

Thanks.

I have vw warranty that I pay for monthly otherwise the turbo would not be covered.

I had the same on mines, it was the mount holding the downpipe was loose. Get a look underneath and see if theres any play in that area.

I have this noise but it sounds like it's coming from behind the fabric in the bulkhead.

Not coming from exhaust/downpipe.

Probably the metallic heatsheidling tbh.
The car boosts to 12-13psi and pulls back to 7-8 at the redline.
Idles at -20inHg.

Don't think it's actuator related.
