More details please?

Is it a mechanical buzz, electrical buzz, any vibrations, like a bee, like a fly, like a missed gearchange, how long does it last, high pitched, low pitched, etc?

hard to explain as its only done it once tonight was like buzzing type sound will have to listen out to see if it reoccurs im wondering if it was my imagination now or if ive got a srew loose!!!!! seperately its always had a low pitched hum whenever the ignition was switched on but its always done that

Hehehehe....

My car makes *loads* of weird electrical buzzes. When I turn the ignition on the area near the drivers door mirror starts an electrical shreeking high pitch, the accelerator pedal makes an electrical high pitch pulsing sound, the Climate does a *buzz-buzz-buzz* near the windscreen when it is adjusting the temperature setting.

When I say high pitch noises they are at low-volume but I can here them.

The most obvious one is the fuel pump which is quite high when cold (when the fuel is being sent through the pre-heater via the filter through a diverter valve)

I call it ''exciting'' you know- where your not sure if the car will make it through the day.

Would it happen to be from the passenger side?

You say it did it on a night. It may be like mine. When the lights are switched on there is a electrical buzzing sound, it sounds as tho it comes from the speakers. Goes away when i switch the lights off.

Any idea where the earth could be? Im guessing it could be one of many?

if you take the headlights out there will be a wire that comes from the plug that would go on the bulb, it will bolt on to the body near the headlight, and will either be black or green and yellow

happened again last night i was hoping it was my imagination!! its like an odd low pitched buzzing noise seems to be coming from behind the instrument cluster?

Cabin temperature/airflow adjuster I recon - Mine does it sometimes too! Bl00dy hard to tell where it comes from but it always seems to relate to when you start the car (i.e if the temp was set on cold and the climate control is set to Auto it self adjusts etc..)

Just a guess

seem to have developed a different sort of farting noise from the centre of the dash now?

Seems like the same topic here: viewtopic.php?t=1734&start=15

Air re-circulation adjuster was what I meant in my last post

Yep i get that and a hum/whir which i have managed to track down to the sunroof motor - just sits there making a faint noise and only stops when i press the open/close button
