Agree with Blue. The plastic impellers on any car are known to break/wear down. BWM & Jeeps use these and they all fail. AOS is the most likely issue and the car sitting for so long.

Best thing to do is to just replace the AOS, clean out everything, drain the oil, replace the filter and fill to the correct amount. Would really replace that new WP with one with a metal impeller, then drain & fill the coolant.

All in all should be under $300 in parts plus a day in the garage to do everything.
