WHOOPS!! I think this is in the wrong section... The car is a MKVI - 51 reg
Ok, I think there's a problem with my friends 51 reg Polo.. After having an alarm fitted, she's noticed a 1 second buzzing noise coming from the engine bay each time the drivers door is opened after its been left for a length of time. Its the same sound that the engine makes when you put the ignition on.. Is this normal, or would it be something to do with the alarm being fitted? She can't remember if it did it before the alarm was put on.

Many thanks!!!

i get that with mine
i goto my car unlock it open the door and you hear a 'zzzz' like a cd player sound, mine is a base model, no electrics so its not the alarm mate
anyone know what it is? lol

So its probably not a problem then? Does it do it everytime?
She said it doesn't do it everytime.. only when the car's been left locked for a few hours, or overnight.
The sound only happens for about a second or so...
She's not been able to replicate it whilst i've been there, so I'm starting to think she's gone mad, but she swears it happens! LOL

and has yours done it from new, or is it something that developed after some time?

well i live up a really s**t road you see and it gets quite muddy at times and it seems as if it does it after i've driven it through the mud, i was thinking more along the lines of perhaps the rear drums letting in dirt, because the morning after it would really squeak when applying the break, its just a theory but mine hasn't done it since i cleaned the left rear.
and no it didn't do it from new
OOPS THIS WAS MEANT TO BE FOR ANOTHER TOPIC!
DAMN DRINK

No, this noise only comes from the engine compartment... any is only when the drivers door is opened. Its as if something is triggered by the door switch ???

This is normal, happens to me now and then too, only when opening the drivers door I think

Hope helps

yer this happens in my 9n too, everytime i unlock and open the driver's door, after it's been stood still a while

Excellent! thanks very much guys! A great releif to hear that!

Anyone know what it actually is, just out of interest?

havn't got a clue lol

mine does it as well, i always thought it was the fuel pumps opening or something of the like in the engine

it opens when u unlock then open the drivers door and u can hear it close if you leave it to sit for about 10 mins

nothing to worry about

I get this aswell bud, strange thing it is must be someone on hear that knows what it is

Yes, it is indeed the fuel pump priming / starting - so that when you turn the key, you can set off quicker (hence no need to let the engine 'warm' up being stated in the car user manual)

haha! what a guess from me

nice little touch!
