Gurgling expansion tank

[M400DPC]

After a spirited run and the car has been switched off the tank started gurgling and didn't stop for about 5 minutes. Is this normal? Never heard it before...

mine does that. I guess it's some localised boiling from heatsoak when the engine isn't running that causes steam pockets to form.

its because the turbos are still hot and they are water cooled, so water in them boils and the steam/air goes quickly to the expansion tank.

Perfectly normal on a stock or modified noble
