The exhaust is sound, and the noise occurs when stationary, not in gear and without the clutch depressed (though I am).
Any ideas - can it be a misfire with it being a tdi - I don't even know if a tdi has spark plugs . Could it be a turbo fault as the noise disapears at 1800 revs (can the turbo jam open).
any pointers would be useful
cheers
