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

Im not happy if this is going to be the case with mine when i get it in a few weeks!! Its sounds like they all have it.. Poor effort VW.

You'll have to add "waste-gate flutter" to your long list of options MK6

I got it too, I get it more when I am in Drive, much less in Sport (in the DSG) prolly cos I am not spending too much time in the hot-zone of revs when I am flogging it.

I don't mind the sound much now that I know what it is. Maybe a new Stage III turbo from Volkspower will get rid of it..

I must be a Camry type driver then, I haven't noticed this rattle.

Is it really that loud, like will you notice it if you dont "look" for it?
Is it that bad that you can't live with it?

It is not really that loud but under specific condition (slightly faster acceleration ... on about 2000rpm) it is, for short period of time, overpowering that GTI normal ( sound generator generated) exhaust noise.

For me it is less annoying than 118 TSI squealing noise BUT STILL ANNOYING.

I hate it and would be willing to pay a 3rd party to fix it if they could. However, my opinion is that VW should fix it under warranty. It is a characteristic of the car, but an unwelcome and unintentional one. It's like Toyota saying their "uncontrolled acceleration" is a characteristic of their cars and doing nothing about it. Well.... not quite....

For me, the sound occurs at a very common level of acceleration where the engine and road noise doesn't disguise the rattle. I was willing to overlook it when I wasn't sure what it was but knew the car was under warranty. Now I know what it is and know it won't be fixed. That gives me the

Why dont we bombard VWA with complaints??

Perhaps start a thread to bring it to everyones attention with a VWA contact email etc..

Maybe an idea? I mean i dont know mine has it, but it probably will by the sound of things..

Thoughts??

I'd probably say you need to wait until you know whether it affects you or not before taking action?!

I've never bought a brand new car before and I'm going to be mighty pissed off if I spend $45k and find out it has some annoying noise out of the box which they refuse to fix...

I took my GTI back to the dealership to assess the rattle after making an appointment with them. I took the workshop foreman with me for a drive and deliberately drove it in the rev range that usually generates the rattle. He admitted hearing the noise and even went so far to say "Yeah, I've heard it before, but not as loud as this". He started telling me that it may be something to do with the exhaust.

After we got back to the dealership, he took it to the workshop to put it up on the hoist to see if there was anything loose under the car etc. I think it was all of about 10 minutes before he came back and said that it was the operation of the turbo when it hit boost, and by his tone, it sounded like he'd encountered this before, or at least, he'd read a pre-prepared script on what to tell customers with this problem - an FAQ almost.

He explained that the rattle is caused by a disc that is responsible for opening the feed pipe to the engine, which is attached to a rod that the vibration/rattle also travels up, making it sound more pronounced. I should have asked if he had a diagram to show me exactly what part he was talking about, but I took the car into them in the morning and was running late for work. He told me that there was no fix for the rattle and that the car was operating as per normal.

I've been in quite a few turbo-powered cars, and none of them have ever rattled as a result of boosting. It seems very odd to me that a car maker with the reputation for quality that VW has would produce an engine that made this noise, and then pass it off as normal operation. I've been trying to get used to the rattle as normal engine noise, but it's ruining my experience with what otherwise is a brilliant car. I haven't completed my customer survey yet, so I might make mention of it and see if it provokes anything.

It's a real shame, as I've only ever owned Commodores before the GTI, and although Holden doesn't have a huge reputation for quality, I never really had any issues with any of them like this. It's disappointing to have made the switch to a different maker based on their reputation for quality and to have now had this experience...

Maybe a Current Affair will solve the problem

That show never solved nuthin but the mystey of where old journalists go to die ...

I have the exact same rattle from the time i picked it up. I waited a week to see if it would quieten up....... but it didnt. I called up the stealersip and they told me to bring it in for a technician to look at it. I took it in on friday, had a technician come for a ride and within the first minute told me he knew what it was. He the proceeded to inform me it was the wastegate vibrating as it is opening.

Just like the post before, he gave me a printout,


Customer statement / workshop findings

Rattling or jarring noise from the engine compartment / exhaust system when accelerating between 2400 and 3000 rpm .

Technical background

Waste gate adjustment rod of the turbo charger rattles when accelerating.

Production change

---

Measure

Do not repair, the noises are construction-related and normal. There is no parts damage.

Warranty accounting instructions

This is no fault in the sense of warranty.


I have had a few turbo cars which I have modified and never come across this issue. I had a MK V GTI as well that never rattled. The tech advised that its a peformance car, and these noises are to be expected. Its a new engine from VW, and thats why my MK V didnt make the rattle. I would understand this if they told me it was a new turbo, a new design or material used, but if its the same as they have used on previous models there should be no noise.

I am still trying to figure out how a small rod can rattle so loudly. Im still convinced its a heatsheild / exhaust rattle. Come on VW, you can do better than this....... I hope.

I feel that if you guys are not happy with this, the only way you're going to go about finding a solution is to go to a VW specialist who is not a VW dealer.

Isn't that a sad statement. I totally understand what you mean but it's so understandable why people are frustrated with dealers. It was the same with MINI dealers where they would deny problems until a collective of owners got their info together and could provide some evidence.

[Corey_R]

And that's what I'm saying. For all we know, what VW are saying is correct. Annoying, yes. but wrong, no.
So if you want some change to be made, someone who feels strongly enough about it needs to do some leg work of their own and determine what the issue is and what the resolution is.
If it turns out to NOT be the Waste gate adjustment rod, then there is grounds to approach VW and question them.
