When opening drivers door a buzzing noise sounds from under bonnet for a few seconds , this occur's if the car is left standing for varying period's of time, quite a few people have asked is this normal??. The panda is a 04 1.2 active duallogic .Got this car last year alway's done this so no concern until other fiat owners none panda have alway's commented

Welcome to the forum Kevin,

Does it sound mechanical or electrical?

Whereabouts under the bonnet does the noise come from? (Maybe try it again with someone listening and the bonnet up?)

Does it always happen when you open the door or does it happen if you just leave it ticking over?

If so, could it be the electric fan kicking in?

On the dualogic, doesn't the pump for the gearbox run itself up to ready for starting?

My mum's did this, it perfectly normal. Sounds like a fuel pump, i know it's not, but that's what it sounds like. Could be the clutch reseting itself or the gearbox fluid being warmed etc. Nothing to worry about.

I think its the fuel pump priming there was a topic on this yonks ago, could be wrong though...

Yup, fuel pump priming. Even my diesel does this.

Have you got a bee in your bonnet?

Just when you open the door?

On the Alfa 156 Selespeed the pump for the Selespeed Gearbox starts then the door is opened , I think the Pada does the same

Yep, when opening the door or switching on the ignition- it's the pump priming the gearbox hydraulics upto 60bar (if needed) so it's ready to pull the clutch in, and if necessary, select neutral on start-up.

I'm pretty sure the Ibiza courtesy car I had did this too

As Danny says its the gearbox hydraulic pump, fuel pumps dont activate unless the ignition is switched on.

How come these posts get a 'thanks' and my warm welcoming one doesn't?

Also when a member joins the forum and posts a question (which is presumably why they joined?) which then gets answered....Is it too difficult to come back and post a little message to confirm that the answers helped solve the problem?

Just a thought!?

there you go, a pat on the back from me, lol

Aww thanks...Have one yourself!
