BMW Z3 NOISE PROBLEM

1998 BMW Z3 • 4 cylinder 2WD Automatic • 125,000 miles

For the past week the first start of the day brings a loud howling noise. The noise ceases after approximately 3 minutes of driving. If I park (to shop etc.) And return within 30 minutes or so, there is no howling on restart. Any ideas? Thanks!

There is an electric air pump that operates when cold. It may be the source of the noise.
