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?

[balkanac]

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.

Yeah i had that problem also, more like a grinding sound, only for a second. but it seems to have gone again. Might be worth while jsut getting a new 1? apparntly they can be a pain to fix as in your case fixing it doesnt always work. but thats just what iv been told..

yeah its a similar grinding sound, like was just wondering if it was gonna cause any damage to the car in the future, so i'd get it fixed but if its nothing its cool then, thanks guys.

If it is the starter motor it should be ok on hte rest of you car (as far as i know anyways) I was told it could make that sound everytime you start forever, and keep working, then one day just stop. So be prepared for the day it does incase its tomorrow haha good luck!

Being in the motor trade (even if for only a few months), the only thing I could think of that would damage your engine itself is the gear on the end of the starter-motor shaft ripping up your flywheel and its own teeth, but that's pretty extreme.

I am not 100% sure, but as I said with my minimal knowledge it shouldn't harm the car whatsoever if the starter motor is dying or making weird noises. Unless of course, the grinding is the teeth slipping and ripping away at both gears.
