I had the same problem but with the Turbo to the manifold and it ended up been the dog bone bush had gone thus making the engine move more putting stress on the manifold

Have a look at the mount, it could be that?

Does it cause blowing? or are you just wrenching periodicaly to check them

Never heard of it. Maybe an older model problem?

I was also wondering about this!

My manifold is loose and makes a rather embarrassing blowing noise. When I went to inspect it I found one of the bolts to be missing so I bought a new one (£6.80 from Audi

) thinking it would sort out the problem.

It didn't.

Lock tight?

Lock tight?

Wouldn't the heat from the manifold/Turbo burn it off?

Thanks for the info Chap's

The bolts just seem to work there way loose

then i need to take of the charge pipe and access the bolts
and re-tighten.

the dog bone bush is it visable from the top side of the engine?
