I've read through some posts regarding a knocking/vibrating noise that seems to point to the DM flywheel, but as far as i can make out this is only on diesel models. Its a 2.0T just done 70k, I had a look and listened for where its coming from and sounds like its coming from the gearbox but im not entirely sure.

Can anyone offer some enlightenment on this as I'm 400miles away from my mechanic(my dad) and cant get it looked at till end of next month.
