engine noise

[TeriM]

Hi

guidance would be appreciated for a defender 110 - 2024 MY PHEV

I have an engine noise like a whine for about 90 seconds + from the engine. This is after I turn of the engine. Mostly when I drive 20+ KM in a hybrid mode. I have not seen or heard this in any similar large SUV hybrids like Porsche, Audi.

Is this a fan issue, burning of gasoline...residue, poor gasoline from pumps (put a 98 octane, same issue).

Advise
Thanks

Sounds like the engine cooling fan.
There is a software update to correct this issue.

Electric cooling pump or thermal management system.Hybrid and electric vehicles often have electric coolant pumps that operate after shutdown to cool the battery pack, electric motor, and associated components.
