Whistle sound from GTI engine... Water Pump Failures

[team_v]

I'm not doubting that euro r a better car to drive, that's why I chose this over another jap car, I wanted something "nice". But what he is referring to and me as well is outright reliability. No one can argue that jap cars give less headaches on avg. But again I took a chance on owning a nice car with the chance Of potential dramas later.

I actually didn't like the dsg, that's why I didn't buy the polo gti which was my first choice but I'm happy with my choice of the golf gti. I got the colour I wanted and I'm slowly building it how I want. I'll see how this Pcv thing turns out

Let us know how it goes.
I heard the same noise when i was driving today and our cars share the EA888 engine.

Got same high pitch noise on a brand new gti mk6, had one water pump replaced, which fixed the issue for a few weeks
Now it's back and was told by the dealer that another water pump and expansion tank needs to be replaced now. Part coming from Singapore which is another 3 weeks wait, I guess survey forms a good for something

Hmmm, wonder why they say water pump. The mechanics at European autotech thought it might have been the water pump or some sort of pump but they put the stethoscope on them and no noise came from those parts in my car. That's why Derek told me Togo back to the dealer.
I'll see how this Pcv goes if it ever comes in stock

Eskimo,
I am a little concerned about your double water pump replacement.
I have had the call, parts have arrived, water pump to be fitted Monday, stay tuned.
Interestingly the whistle has gone or is not as detectable as previous. I am about to install a Catch Can so I really do not want to have to take the Gti back again ( for obvious reasons).
I will report the service outcome.
**** Just where is the water pump located, as before the whistle was more prominent front of engine between alternator and throttle body.
Regards John

Hi John,

Yeah i thought that the new water pump would definitely fix it, as this issue is not so common. even on the overseas forums many experienced this problem on low km's. A couple of them mentioned that they also had to go onto a second water pump before the problem was fixed, which was a surprise to me at the time. My car is going back into the dealer in about a week. so we'll see what the results are after that. I'm not quite sure exactly where the water pump is located. On the first replacement pump, when the noise came back, it was not as loud. I'm hoping that they just fix this issue, as its becoming a pain to keep taking it back to the dealer. Takes the fun out of owning a new car. I'll keep you posted with my outcome.

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?

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.
