Whistling noise when cold starting 97 E420

My '97 E420 with 90K miles on it has started to make a low volume whistling sound right after cold starts which lasts about 10-20 seconds. The noise seems to come from behind the center of the dash, and is not related to the climate control system. The car otherwise starts and runs well. Any ideas?
