Buzz after shutdown

Hi to all, in my 124 I hear a kind of 'zzzzzzz' buzz coming from under the bonnet after shutting down the engine. It's lite, lasts for around 30secs and looks like an electric motor running.
What's that?

It is the pump that moves fluid through the turbo after shutdown....provides longevity for the bearings
ok, good to know that they added this feature.
This means it's not needed to stay with the engine at idle for a while after a tough ride...nice
