Yep...tippety tappety ticketty..when i heard my first gti up close at idle, I thought there was a loose cover in the engine!!
All normal I think.
ha ha - same here, sounds like a dirty diesel. My neighbour has a diesel X5 and the GTI drowns it out

Couldn't believe it when I heard a MK5 GTi for the first time but seemed to be the case will all the subsequent GTI's I looked at, although I don't remember the 2.0TFSI on an A3 sounding as loud (maybe it has better sound deadening in the engine bay)
