engine chirping

[Franklin_12]

There is a chirping sound coming from my 2005 X5 4.4i. This only seems to happen when the engine is cold and there is a lot of moisture in the air. The problem seems to go away when full warmed up and driven. Just curious if this is something of concern or not. Doesn't sound like a belt, perhaps a pulley? Thoughts?

Sounds like the tensioner. Mine does the same thing when the air temps are low. When they are REALLY low mine does more than chirp, it is a loud, pulsing squeal. Belts are all fine, but one day I will give in and get the belts, pullys and tensioner replaced.
