Whistle sound from GTI engine... Water Pump Failures

[walbjj]

i doubt it, no whistle since i got my water pump replaced, and that was 2 weeks ago and ive driven about 700km

Yep had pump replaced and no whistling since, see how we go.

They also polished the front windscreen for the speckles in the sunlight and it seems a bit better now.

Well today I noticed whistle again!!!!!!!!

I released pressure at reservoir and it stopped. Will monitor and see if it persists. If so will be getting that done AGAIN along with the rattle clip fix.

Has anyone else had their whistle fixed and then it return???

Dear JPanDAX,
Interesting you should mention relieving the reservoir cap. I did not have a problem until I topped up the coolant. That is when I noticed the whistle. You can read my previous post, I have not had the water pump replaced and the whistle has not returned.
I wonder if removing the cap has some temporary reaction in regard to the whistle. Strange I agree, but we will have to wait and see.
I still believe that there is more to this than just swapping a current w/pump for another current w/pump, I mean surely they are not like capacitors with massive tolerances.
Regards John

I started noticing the same whistle a few days ago (my GTi is only 2 weeks old, now with 500km). After reading some of the above entries, I released the pressure in the reservoir and it stopped immediately.

JPanDAX, how soon did the whistle return after you released the pressure?

take it to the dealer to get warranty on it

I've read about the squeal problems on the 118. Does this only happen on the DSG or does it also occur in the manuals? I've noticed a soft whistle/squeal sound on a manual I'm considering. Only happens in 1st and 2nd gears below 3000rpm and you can't hear it if the radio is on. Not sure if this could be the water pump issue or is just the normal sound of the turbo.

Does it stay on if you turn off the aircon?
Some members have confused the recirculation fan sound with a engine bay noise.

air con was off but fan was on low setting.

Since you mention 118's, are you sure this isn't the water pump/supercharger clutch issue?
