Randomly and intermittently - my 2010 X6M makes a loud, screeching noise at initial startup. It goes away in one second, then the engine fires up. Who had this issue?

134,000 miles. Water pump done, at 109k. The sound is gnarly, kinda like a chalkboard being scratched... but lasts only for split-second.

TIA
