Short Whirring Noise On Opening Door

[frogeye]

Hi,

 

I hope that someone can shed a little light on what is making a short (2-3 second) whirring noise when I open my drivers door - getting into the car, rather than getting out. I've just popped outside to refresh my failing memory with some detail. The V6 gal has been parked up all weekend, I've opened the door (wasn't locked so no key/remote involved) and this noise starts as the interior lights flick on and stops seconds later - door still ajar. When I try this again a second time, no noise. It seems that the car has to be left for a further period of time (hours) before this happens again.

 

What is it?

 

It sounds like it is coming from the dash area or maybe the back of the engine bay, it's pretty hard to tell. It sounds very much like a pump priming, but surely nothing should be being triggered by the door switch? Any ideas anyone?

 

Thanks,

Fuel pump primes when you open the door to pressurise the system and assist instantaneous start. Standard on all VAG petrol models. If sufficient pressure exists in the fuel system it doesnt do it hence the "does it after its been stood"

Thanks Seatkid - you do know your stuff!

 

I cant think that I've ever heard this on my 2.3, just the 2.8, if the 2.3 ever runs again I'll keep my ears peeled (or whatever it is that ears do).

 

It's good to know that this is normal though.

 

Thanks again,

As the 2.3 is the Ford engine don't get worried if you can't hear the pump prime.
