What would cause this noise when unlocking the car?

Hi

I've noticed that when I unlock the R230 first time in the day, there is a distinct whirring noise coming from the engine bay. Don't recall it happening before, but I've noticed it a few times recently - nothing on the display etc. Seems to only happen when I first unlock it.

Its not very loud, but definitely there, like a pump is running.

Any ideas?

Sbc pump priming. They all do it.

Thanks, at least I know its normal now. Can't believe I didn't notice it before.

If you own an R230 you're always listening to noises and praying they aren't the harbinger of doom. My car brings me nothing but joy, but I'm always listening.

Ain't that the truth! Like the way you put it, really sums it up well.
