Whistle sound from GTI engine... Water Pump Failures

[dood]

tyhat's what I'm trying to determine. Is the waterpump issue specific to the dsg model or does it affect manuals too? What are the characteristics of this problem?

Slam - have not had chance to drive much lately but in the last couple of short trips I have not noticed the whistle since I released the pressure at the reservoir cap. I will keep an eye on it to see if it occurs again.

Dood - according to VWtechs it is the water pump and don't believe it is specific to DSG or manual. You will know you have the problem as it is quiet a high pitched, noticeable sound!

Thanks JPanDAX. I've only done one 10km trip since releasing the pressure, and I haven't noticed the whistle either.

Dood, mine is a manual and JPanDAX's is a DSG so yes, it affects both gearboxes.

Hi,

GTI MY12, 850 Km, whistling noise started today

This is quick iphone recording of the high pitch noise on my MY12 GTI.

not sure is it easy noticeable because of engine noise.

That is certainly a high pitch noise....does the volume get louder with engine revs?

Not sure - have not tried

First time noise appeared last night (oil temp was 101 C) and I noticed it when I was parking.
In the morning (engine cold) I released the pressure at the reservoir cap (not much coming out).... and after 4km driving noise was back - oil temperature less than 95C (that is when I recorded it).

I assumed when releasing the pressure first time - engine was cold and pressure was reinstated to "normal"... by driving it small distance (4km) pressure still reached whistling level....
so second time I released pressure while engine was still warm... when cooled down pressure in the reservoir was below "normal" (not coolant level below Min) .... if it make sense

After that I did more than 100km different driving conditions... oil temperature reaching 100C... no whistling ... my thinking - to reach whistling point pressure must start building from below normal... but it is still just thinking

I am still going to contact VW dealer.

Update......whistle is definitely back and is getting worse. Took it in to dealer and they have ordered new pump (again). Install should be late this month as well as the waste gate rattle clip at same time. I asked about the pump and they confirmed that the one they installed last time was the newer version. So not sure what is happening.

Still same deal - release pressure at reservoir and whistle stops for a while. Hoping this second time will fix it once and for all. Any one else had problems after second pump replacement?????

Will update when done.

Hi JPanDAX,

Do you mind telling me which VW dealer you've been dealing with? I will refer my dealer to them if they haven't come across this water pump issue before.

Slam - Southern Classic Cars in Wollongong. They seem pretty good so far. I didn't buy through them, they are just my local dealer (5 minute drive from home) but they seem keen to help!
