funny sound on start up.

[GtiLER]

i drive a mk4 gti golf and when i start her up i hear a wired winding/weezing sound coming from the engine straight after then engine starts up. the sound only goes for like a second. just wondering has any one had this problem? and know how to fix it?

i think thats the vacuum pump. I dont think there is anything wrong with it

[Umai Naa!!]

In concurrance, it sounds like the air pump. Nearly all the MK4s I've dealt with make that noise.

[balkanac]

Yes thats it!! an air pump!! thanks mate

[VDUB-BUD]

I've always wonder what that was. Good to know it's a feature.

No body mentioned the starter noise.
I've had trouble with my starter running over on startup. Have had it fixed 3 times now. Can sound like a duck under the hood.
