2007 3.0 TDI done 113k. with an intermittent start up rattle/clatter. Its a 2 parter, about a second after it fires up I get this noise which lasts for less than a second noise falls off but just before its completely gone then comes back again for less than a second. Obviously this all happens quickly. I have had it at my local indy's and sods law it didn't do it, It does it warm or cold. I have read about the tensioners on the earlier models but its no so much of an issue on the later ones. Its also really hard to pin point exactly where this noise is coming from. Idea's on a Postcard
