Default Strange noise..only when starting and in low gears at low rpm, I hear a rattiling. No leaks...

Just a loud rattle sound then it goes away but it has gotten worse lately. Any ideas?

Is yours chain or belt driven ?
if chain I would seriously suspect chain tensioner. Will go when warm as oil has lubricanted sufficiently

low RPM and not related to hot or cold i would suspect a driveline relation. Maybe shaft bearings?

I’m still gonna say Chain tensioner(s) thats of course if your 3.0tdi has chains.
Noise will reduce or go when warm because the oil is thinner and has whipped around the crankcase. Sometime won’t make noise on really cold starts (?)
is it a noise that lasts for about 2-3 seconds (?)
noise will get worse as the guides wear more and more.

big job. Gearbox needs removing for a start. Got mine done for 1500 Euros so wasn’t too bad. Audi quoted 4000€

Just a quick question ?
does this noise sound like a grumpy old diésel clatter noise ?
does the noise stop the moment you take your foot of the gas ?.

I am guessing after 15 years the poster solved this.
