engine noise when cold

[mri_ice]

Hi all,

My T6, 67 plate, with about 70K miles makes this noise when cold. It does pretty much go away when the engine is warm. It's the 102PS engine.

I had never noticed this, but when taken to a bodyshop place, it raised eyebrows as "not normal".

It will go in for investigation on Monday but I'm very curious what everybody else is thinking (hearing). Should I be concerned?

Many thanks

Martin

Can't really tell from my phone's sound quality.

But common noise causes can be, belt tensioner pulley?. High pitch squeal.

Or DMF?, it rattles.

Or Leaking EGR pipe? can cause air leak hiss... But is constant and comes with a exhaust smell.

Keep us posted....
