2004 BMW 330Ci engine noise

Hi,
On my 2004 330Ci with 220,000 miles.
When cold the engine makes a loud whine noise especially when accelerating, goes away when at operating temperature. Also there is a lot of mechanical noise inside the engine, goes away after engine is warm.
Big problem, or little problem?
Thanks

Depends on the noise but I'm guessing it's not good, either way.
