Golf R Metallic Ringing Noise

[rosslm]

Hi All,

I've posted something similar on VWGolfAU, but figured it's worth posting here as well.

I've been following this thread and others like it for a while, even more so after my Golf R developed the rattle under load between 1500-2500 RPM.

At 2439KM, I put my car through for a warranty service. Going through the invoice, the warranty work was performed in conjunction with TPI 2041451/2. The warranty work took about a day and a half (also had a window switch issue which contributed to the time taken) but I can confirm that since the work, I've had no rattle.

I checked my turbo revision before and after the warranty work to document the issue (pictures available on request):
Old: 06K 145 722H
New: 06K 145 722T (also listed in the parts listing on invoice)

I've done a bit more research and found that since the H revision, there has been 4 further revisions according to APR in this post - N, P. S and finally, T. It's still early days and only driven the car once since pick up, but I do not have any rattle!

I know I'm more likely to be the exception and not the rule so I'll keep you guys posted. If anyone's in Sydney (Hurstville area), I'm also happy meet up, have you look and listen. It's a frustrating issue to say the least with half of us having to go Stage 2 to fix the issue on an otherwise amazing car so I hope this comes as positive news..

Edit: My build date: 04.2016 (not sure if this will come in handy)

I have a 2016 R build week 42 2015, now done 21,000km I checked my turbo it is also 06K 145 722H the R has been a fantastic drive even more so now with the JB4 upgrade. That being said I have heard the 'bell' sound occasionally around 3000 rpm but it has never really annoyed me, perhaps because I'm usually going through 3000rpm briefly while accelerating or because 3000rpm in sixth is well over legal freeway speeds, I am also older so my hearing would not be a sensitive to the higher frequency and with so many other good sounds going on in the R it is not so obvious. But that is good info keep us posted on how the 06K 145 722T version performs.

Hi all,

A quick update - I've since driven the car a little bit and still no rattle..

I'm also think that they changed the orientation of the heat shield as before, it was in between the turbo and the bonnet and now it's between the the turbo and the engine, but I'm not 100% sure on this point.

I'm definitely chuffed that there's not more annoying rattle and tempted to say that the 722T revision may be the fix we've been waiting for.

Hi everyone,

An update from me.

Turbo was replaced with the 'T' revision last Wednesday. Unfortunately, this hasn't fixed my issue. 'Rattle' is still there.

I guess my only option now is an aftermarket down pipe. I'm sick and tired of the back and forth with the dealer and getting told 'Road tested and OK' every time I pick up the car.

Here's a video of the rattle (After ALL the "repairs"). Sorry it took so long to post it up and for the wind noise from the vents. https://youtu.be/DxOM_6hmtH0

Cheers

As an FYI i have read the 17 models have a revised downpipe, ill see if i can find any additional info or part numbers.

Thanks mate. Would be interesting to see if they changed the flex cage.

Any luck with finding more info on the revised DP?

Hello, people of Australia.

Just want to chime in with a data point from the states, because this thread in particular has been so chock full of information on this issue.

I just installed an AWE downpipe. Not sure if you're familiar with this brand, but it's from one of the only companies in the states that guarantees no CEL without a Stage 2 tune. So I'm running with this downpipe, and the rest of the car is basically stock: no tune, stage 1 or otherwise.

Rattle is still there. If there's any doubt, it's much like vw747's report (YouTube) with a faint, high-pitched ting-ting-tinging on load; particularly bad going up hills.

Dealers here don't seem to have the patience to diagnose this issue, and as far as I know no TSB/Recall or any word from VGA on it either.

For reference, here's what the AWE downpipe looks like:

Hi
I have a 110 TSI and get the metallic ringing at low speeds and on acceleration. Been there since day one. Seems this affects all Golfs?

[TFAD]

Anyone have any thoughts on whether the Akrapovic titanium exhaust that you can spec as an option on the 7.5 Golf R might fix the problem..?

[Ceres_mining_co]

Has anyone considered the wastegate actuator rod rattle that affects TSI 2.0 engines? (Covered in the GTI 40th edition thread)

I've got the same issue with my 103TSI. Seems to correlate with the amount of fuel that I'm sending into the engine as far as I can tell and it's more audible in cold weather. I just had the turbo actuator replaced and the issue remains and is almost identical to when I dropped the car off. The noise wasn't there when I picked it up new and it wasn't present on any of the 90TSI engine loan cars I've borrowed. I also didn't notice it at all on several 110TSY MY16s I have been in as an Uber passenger (including one I test drove).

I've got a case with VW customer care but not seeing much traction yet.

I need to add my MK7.5 R to the fuel line annoying buzz list at about 1000km after starting to rev the car more I noticed a buzz from the drivers foot well area, particularly noticeable in S mode slowing for roundabouts corners etc, the buzz was their 25% of the time in these situations from about 2300 rpm it could even be replicated at times in neutral from 2300 rpm. Having had a MK7 R with zero noises this has been annoying. I mentioned it at the 1500km checkup the tech acknowledged the buzz, checked trims etc. but the buzz was still there I had a longer run have now done 3000km buzz still there. Went back to the dealer once but no buzz. But I could still replicate it on any given day. I have gone through a lot of forums and everything points to the fuel lines after leaving the engine room into the under floor channel, nylon ties and packing appear to be the fix.

This is the noise mentioned in another post

YouTube

This is what I did as a temporary fix 2 layers of adhesive felt stuck together about 20cm long 3cm wide with 15cm cut twice so as to dangle and then pushed cut end into the channel from the engine room below the brake booster, stuck a few cm to the plastic fuel line cover, result is zero buzz quite amazing.

See the felt stuck onto the plastic fuel pipe cover as it exits the engine room



I've got the car booked in next week hopefully to get a permanent fix.

It's pretty amazing that such a minor detail can turn into something so annoying, can't see how this is overlooked in production, it obviously doesn't effect all cars but one is too many.

Apart from that the R is fantastic.

Just to add there is no evidence of the turbo ringing noise in the new 7.5 R which I had in the previous R, it never did annoy me in any case as it was not that loud and very brief in duration at 3000 rpm.

I've just come across this thread...

My MY16 7R has just had its 2nd 30,000km service (with 29,000km on the clock), I reported a long list of items for the dealer to investigate, the main ones being:

1. The parking brake (the green handbrake light) sounding like it wasn't adjusted properly (pads rubbing when the car was cold)
2. The gear stick reverse collar sticking after reverse was engaged and 'popping' up.
3. Metallic rattling sound from the engine bay at around 2,000RPM and loud enough to be heard even when in Race Mode.

The first one was (mostly) fixed with a software update (although it's not quite right and has introduced some other gremlins like refusing to engage at all).

The second one resulted in a physical fix of some description which has vastly improved the entire gear-changing process. The gear stick now engages in every gear far more positively and there is less slop and play when traversing neutral.

The third one requires a complete replacement turbo and the rattling is getting louder. Replacement was meant to be today but will now be next week instead. It will be done under warranty.

How long have you had the rattling around 2000 rpm, sounds suspiciously like the fuel line buzz (also sounds a bit metallic like a heat shield) very noticeable negotiating roundabouts and corners in S mode as the gears changed down increasing revs into the 2000-3000 rpm range my previous 7R had no fuel line buzz but I could faintly here the turbo bell ring at 3000 rpm but this never was annoying unlike the fuel line buzz.
