Whistle sound from GTI engine... Water Pump Failures

[walbjj]

im actually concerned that ur service guys r saying its a water pump, yet my guys said it was the pcv valve.
guess ill find out on monday when i pick up the car

[eskimo]

Let us know walbjj once you have picked up your car if it was the pcv valve or water pump

[walbjj]

Ok Pcv installed and it didn't do bugger all. They say it's the water pump. Bloody idiots. It's like they r guessing what it is and hope it works. Anyway booked next week.
What's the bet it goes away and comes back?

[Corey_R]

Well you know... they probably ARE guessing at what it is. Though, you'd have it's a well educated guess based on experience.

It's no diff to a lot of industries. Like with computers. You have a fault, it could be a few components, and if the "diagnostics" don't come straight out and say it's the 1 part which is faulty, you just have to change the most likely to see if it resolves it. Then change the next. And if necessary, the next...

No different to visiting a doctor for a lot of illnesses.....

[walbjj]

Fair enough, but it's always annoying when u take ur car in once to get it diagnosed, then again toget the "part" fixed, then again to fix the "actual" problem part. And inthe cases above, it may not resolve it. And then what are the chances that 3 years down the line, it happens again.

[Corey_R]

Yeah - I guess the problem is it's just not possible for every dealer to stop every part, so they need to get the parts in (though it'd be nice if more were stocked in Australia rather than singapore etc). So even if they were stocked in Australia, you'd need to elave your car for 3 days etc to have the best chance of it being resolved.

Hello all,
Gti is back from Service Dept.
+ + + AAA to walbjj, let me recap.
Gti went in for 1500klm 'service', notified service of whistling noise. Noise confirmed, service want my car possibly for a whole day, appointment made. Car left at 8.30, received call at 2.00, pick up car, fault is water pump, nothing in stock.
Received call, parts in, appointment required. Rang service, Monday 18th will be o/k ( a little surprised that I could be seen so early ), checked that techs will be available ( again cautious ), asked how long is allocated for pump replacement, 4 hrs, o/k I will wait ( now I do not have to take two cars over, 1.25 hrs each way).
Turned up today 8.30 and settled in the 'waiting room'. I could see my car standing lonely by the fence, have I been forgotten ??
10.00 service informed me they want my car overnight.....F/O.
Now what happened ??, did they over book ? ( remember I was cautious), are they not quite sure and want to 'play', is 4 hours not long enough for the replacement. Needless to say I left very pooey.
I have not heard the noise for a little while now, it may return. I VCDS the car, no DTC found, no pending DTC, took some advanced readings of water temperature and other areas. I will contact my mechanic for verification of results and get his advice about the noise, if it returns.
As far the Service Dept is concerned, I will not be back. I may have to choose another Service Dept as I do not think my Vw/ Audi tech may be allowed to perform warranty work.
Very disappointed with this lousy service
Regards
John

[walbjj]

Yeah, they said it will take a day, so altho it's booked for 4 hours, it might take 6 actual hours. My mate that's the Audi service manager says warranty work affects his budget as it's at a cheaper rate plus some jobs take longer than the bookable hours
John, I see ur in bankstown, so I'm not sure which dealer that is.
Bill buckle service have been good so far, plus it's only a 10min walk from work

[eskimo]

Sorry to hear that from both of you. I should of mentioned that when I got my first water pump replaced they had the car for 3 days. They said it's a big job as it normally takes half a day to pull it apart.
Mines going in for the second water pump replacement on monday with the expansion tank replacement this time
So well see how it goes after monday.

[johnvw]

Dear eskimo,
I just knew 5.00pm was too early, but anxiety just got the best of me.
Regards John

[walbjj]

ok, car was dropped off at 8am, drove past at 230pm and the car was outside, so i assumed it was done.
went back at about 3ish and the car had been worked on.
havent had a chance to give it a good drive yet, but so far i cant hear anything. ill let u know later, otherwise ill be calling them up tomorow for this expansion tank deal

ok, went for a longer drive. the whistle noise is not as evident, its not noticeable at all when im idling in the garage when before it was like a alarm.
however, when i turn off the ignition, i can hear the feint sound of it whirring to a stop, obviously the water pump slowing down. will this get progressively worse and louder as time goes by, well, as shown before with another member, most probably, but ill come to that bridge if and when it does, but right now, i can check that off the list

[eskimo]

Ok here's my update. Took the car in this morning for the second water pump part no vw06h121026ba and they also replaced the expansion tank cap vw3b0121321, it was just the cap not the whole tank, drove it around today and it appears the whistling is gone. Hopefully this is the last of it. Will see how it goes for the rest of the week, but I have a feeling that I can cross this one off as well now

Thanks Bug_racer. Hehe - a nice heads up from APR there.

So Arin said that the water pump has been superseeded by 06H 121 026 AF, by that was back on 3rd April 2010. On page 3 of the thread, skully states that his dealer told him 06H 121 026 BA is the latest version as of 18th April 2010. eskimo had part 06H 121 026 BA installed too, so we'll presume that this is the latest version and is the solution to this problem.

Hi All, It is all very interesting. My noise is more of a high pitch whistle than that heard on You Tube. I do remember removing the coolant tank lid and topping up ( I wonder........).
Could a very unskilled VCDS owner scan and identify the water pump part No.????
