Cold start whine?

Could anyone please give a listen to this clip and tell me what they think? It only happens on a cold start, the noise will go away after about 10 seconds from starting and won't occur again while the car is warmed up.

Thanks in advance.

I replaced the idler pulley after seeing some threads that mentioned that being an issue. Also kept and eye on the power steering levels, but I haven't flushed the fluids yet.

That sounds awful. I wouldn't be driving it until you find the cause.

Thanks in advance.
WTF is this my friend ? WOW ! My ears are bleeding !
I never heard this before on a S65 !
Personal I think (not sure) it comes from the Vanos-Gears , because you say it happens only on a cold start ..

Advice :
Call your nearest BMW/Dealer ASAP , and don't push your start button anymore!
This sounds absolutely not healty !
Let us further know how it goes..

had my steering pump + idle pulley replaced and can tell you it does not sound like this at all and also should not go away after car is warm. This sounds much worse but i don't think it's anything directly in the engine.

Check your power steering fluid to make sure it's not low. I had something similar and was low on power steering fluid so just top it off.
