Noisey rattle on startup

[Ossa]

I have an 2008 A6 2.0 tdi with no problems till now. Startup sounds ok if the engine is Cold, but once it's been warmed up & switched off, the startup then sounds like a very loud rattling noise, I've spoke to a local garage & they said it could be torque converter !  I am no mechanic so i would appreciate any  help or advice.   Cheers

Ok is it auto or manual ? 

Also torque conventer only exists in 3.0tdi quatto zf6hp19a gearbox , so the garage is talking rubbish 🙂

Thanks Piotr , its an automatic. I have been told by two garages that its a torque converter but took it to a specialist the other day & they told me basically the same as you ( it does'nt have TC in a cvt box ).       Suppose i should of went to a specialist in the first place 😞

Hey Ossa - did you work this out? Same issue on the A6 Avant 2007.... auto diesel. Rattling on acceleration. Mechanic suspects torque converter./
