Buzzing noise when engine switched off.

[Denistpsc]

I’m hoping someone might be able to advise what a quite loud high frequency buzzing noise when the engine (2009 Peugeot 308, 130,000km) is switched off. Location appears to be at the right front of the engine, somewhere near the oil filter. Lasts for about 5 minutes. Thanks.

Mate that's the turbo coolant pump, always runs for 5 or so minutes after ignition turned off.
Sounds like one of the plastic blades may have broken off.

At least you can hear it, when you can't hear it the unit has failed and turbo will overheat!!

Part no 9806790880

Looking at parts, should I be concerned if the part number on the advertised item is 9806790780 rather than 9806790880 as you indicated?
Thanks.
