MK6 GTI - Rattle upon acceleration - Resolved via TPI: 2021062/7

[G-rig]

I agree Corey they are very similar but not worth slagging the new one as it is very good.

It's like all things that come and go in cycles, models go from round to more squared off and hifi gear goes from black to silver and back to black..

From a distance the harder lines in the MK6 aren't that obvious. The shape as a whole isn't radically different to the MK5 so the MK5 owners should be happy it isn't radically different/better.

not sure what all the MKV vs MK6 has to do with the rattle?

Great photo that! I'll take the red one

Anyway:

The MkV is still in front of the MkVI...sorry couldn't help myself.

Get over it!

SOooo predictable that I almost said in my post that "yeah, now Triode will come in and say that the MKV is better cause it's in front".
But then I thought, nah, triode ain't that lame

Wrong again hehe

Just to get back on topic,

Are all the cars with the rattle DSG equiped, or are there manual's out there with the rattle as well?

[mfl]

I have a manual and it rattles in the 2500 -3000rpm band, - apart from the other rattles

I also have a tinny rattle in the 2000-3000rpm range in my MKVI GTI with DSG.

without reading the last 22 pages of posts, has VW got a fix for this?

[Corey_R]

Basically - turn your stereo up!

The parts are the same as what was used on the MKV GTI. So we know that it is very reliable. The reason you hear the noise in the MK6 but not in the MKV is because of the new exhaust design in the MK6, in combination with the MK6 being much quieter overall than the MKV (plus having a lot less rattles in general than the MKV). Due to this, the operation of the wastegate is what you're hearing.

Yeah seems like it's normal and nothing to worry about.

[GTICam]

I disagree. This is crap. We are swallowing the line that “this is a normal characteristic of the vehicle” and going away with our stereos turned up another notch!
Call me cynical but;
Lets say, for the sake of this discussion, that the noise is emanating from…oh perhaps, a poorly designed muffler with a baffle that resonates at 2400 to 2800rpm .
From what Coreying says, (and I don’t know any different) that the engine/turbo on the MK5 and Mk6 is pretty much identical and only the exhaust system is different, then one would expect Mk5 GTIs to have the same or similar resonant buzzing noise…ie same wastgate control rod. Do they?
Now lets imagine you are VW. You discover your new Mk6 product has an annoying buzz in the muffler, and face replacing all GTI mufflers under warrantee. So you try one on. Because GTI buyers are a pretty passionate bunch and love their cars, you tell them this noise is a normal characteristic of the car. To add credence to your story you tell them the noise is coming from a wastegate adjustment rod. If that’s the real problem, I think it’d be no problem to make the rod from a different material or to clamp a small weight onto the rod to change it’s resonant frequency. I also wondered (now this is really cynical, but hey, I’m an engineer), how they found out it was the wastegate control rod.. Think about it. The only way you find something like that is to FIX it. Because the noise occurs under load, there’s no way to see if it’s the wastegate rod that’s causing the noise. (Unless they found a really small VW engineer to ride under the bonnet while someone drove the car! Before you laugh, I’ve seen pics of Bruce McLaren sitting on the front of a bodiless McLaren M8 Can Am while Denny Hulme drove, so Bruce could watch what the suspension was doing. Somehow, I can’t see VW doing that!)
When I took my GTI back to the VW dealer today with a description of the noise and demonstrated it to one of the service blokes, he said there had been at least 4 other customers with the same complaint, but there was no solution from VW yet… when I picked up my car I received my very own copy of the "this is normal" letter.
Anyone tried an aftermarket muffler?

What about poll:

"Are You irritated by rattling noise"

and only for people that are actually experiencing it (on their GTI).

Opinion based on: test drive, friends' GTI, discussions, forums, experience with other cars ... all of this not valid.

Well Guys - here is the thing.

I've already said that if YOU guys disagree with Volkswagen then YOU guys need to prove them wrong!
There is no point all sitting on here and having a cry to each other. SOMEONE who has the issue needs to take it to a knowledgable mechanic who ISN'T affiliated with VW and get them to help!

Now Guy_H has already said that he'd love to hear from someone in the Brisbane area that can demonstrate this issue to him - even if at the moment it's simply because he's interested in what the sound IS, since he's never heard it on the many MK6's he's had through the shop.

If no one here is in Brisbane, then you'll have to find someone else.

But until someone does something, all you can do is take VW's word for it that the noise comes from the wastegate rod, that it's the same build as the MKV, and that there is no issue with it.

I am talking about myself.

"... disagree with Volkswagen then YOU guys need to prove them wrong" ?
VW already agree with me - there is so called rattling noise ... We disagree on character of that noise: for them it is normal ... for me it is slightly irritating (love my car anyway) ... how can I prove them that is irritating????

Stupid question but "Does it mean if You don't have that noise than Your GTI is not OK" or at least does not have character.

Is it mechanically OK not only today but in 3+ years time ... I hope so.

Just as parallel look again in my old story:
First: I was told by VW that squealing noise on my 118TSI was not OK - result w/pump replaced,
Second: when noise come back (after 2 months) I was by told it is normal and it is characteristic of the car (not every 118TSI was blessed with that noise) ,
Third: from Mar 2010 they have new pump for 118TSI (because previous one was OK - according to VWA) and they are replacing some on old one.


Once again with or without that noise ... love my car (would be happier and less worried without it)
