TSI squeal noise problem on acceleration

[saveferris]

Hiya

This was through VW Australia and also the dealership who has chosen to ignore me.

They even said that they would involve my employer because I've sent emails during work hours.... Real 100% bullying behaviour there....

God forbid VW should be inconvenienced in any way... its not like I have?? sheesh.

I like the lemon idea. Where can I get hold of a heap of lemons?

Wow, they really are trying to walk allover you, I really despise this ( walking all over the little man) because i'm quite spitefull when it comes to things like this, i would do the lemon thing, especially on a Saturday, there busiest day. When they see potential customers looking at your car reading the list of problems then driving away......... bottom line pain for the dealer principal.

I'm actually getting angry reading this. Ha!

[QUOTE=Tommy;364623]Hi Folks


My car had a loud ticking noise from the B pillars which VW didn't know how to explain or fix until this week. They removed the doors and windows on my car to see if they could track down the noise. They couldn't. They re-attached the doors and have now put felt and other materials under the black glossy B pillar facade and they think this has fixed the noise.

I noticed that the Italian Golf Forumer reported some fix on the creaking B pilar though google translation left the details a bit vague

I think I'll stick to my hyundai after all. Appears that my reliability concerns with VW weren't unfounded.

I had a similar disaster experience with my brand new Honda civic. 35 warranty problems in total, including a failed engine mount, loose airbag and broken brakes. Kicked up a huge s&$t getting things fixed (got someone at Honda fired in the process) but in the end realised that the best warranty in the world won't help you if the actual car you have is a lemon.

I am really wondering if anyone got the 118TSI DSG but does not have this noise problem????????????????????

My 118TSI has done 2500 kms without any noise or concerns re the DSG, nor any other engine/gearbox related sounds.

Occassionally hear a faint ticking noise from the B Pillar on the drivers side though.......... thought I was going crazy......

However, I haven't heard it for a couple of weeks.

Problem????

If you want to hear the correct issue!!!!! it is when the super charger is kicking in it causes a vibration which you hear as a squeak it is caused by the metal plate gripping the clutch plate on the water pump it is obviously going to cause a noise!!! Volkswagen know this and are in the process of a solution they have not forgot about you!!!! so replacement parts and lubricating are just short term fixes you just have to be patient for the long term fix dealers are being instructed not to do anything eg; replacing water pump or lubricating due tho the fact if you lubricate it who knows what happens the the friction lining of the clutch plate????? Or replacement parts are just being redebited back the the business. They did not build the car so why should they pay for it???? My Sunshine Coast VW dealer has explained the issue to me and i was very happy with what the Foreman explained. I would rather wait for a long term fix than a quick one ie; lube or replacment. I say be patient and a long term solution will come P.s it also happens with DSG's and Manual's also with Golf V 1.4 T.S.I Golf VI's are quieter so thats why the noise is more prominent

Test drive to see what all the fuss is about

I am looking at buying a TSI 90 however with the Comfort package you still get the Trendline seat trim so I have had to take another look at the TSI 118. Had a good test drive today, the demo had about done 3500K, windows down I did hear the so-called squeal once but I have to say I didn't find it to be loud or even annoying. I would describe it a bit like a whip sound probably less than a second. I am sure a fix couldn't be to far away. Compared to myriad turbos I hear waste gates popping, cracking and farting generating all manner of strange sounds this was tame.

Hiya

I've been told that the screech comes from the supercharger clutch. VW at this stage states that this is normal and a known "characteristic" of the car. If this is so, why is this not advised at the time of purchase? They know if they did that they'd lose more than a few sales... This is an issue for sure... a very annoying one.

I was told that whilst testing my car at the workshop the other day, the DSG completely failed. I was at first told that this too was "normal". I now wonder what damage may have been done to my car while I've been driving it around with a faulty DSG? I believe that the DSG is around $14 000 to replace, don't know if this includes labour. My calculations put repairs to my car in the region of $30 000. This is incredible considering that my car is only 3 months old and VW kept saying that nothing was wrong with it.

VW why won't you admit defeat and give me a new car? Its been in your damned workshop for 15 days now with no end in sight. This car is a lemon, purely and simply....

Noise is!!!

The super charger and water pump are the same clutch!!!

[Guest]

Coastie i dont really understand your problem? Would you rather wait for a long term fix? So noise is than gone for good? or just a short term lube or replacement? So the noise then comes back. My bet is they will have a replacement part with a different material for friction lining so noise is forever gone.

How far away is the longerm fix?

Hi There

I just had my DSG replaced under warranty and it seems to have made the supercharger screech disappear so I'm wondering if this is just a coincidence or if the noise is related to the transmisison in some way?

Should not be...as mine is manual and exhibits the squeak..

Back to the MkV, I just returned from a 3200km driving holiday and upon return nary a squeak to be found. I can't make it happen no matter what I do, strange and eerily quiet!

TSI film

Here is a good overview of the technology, I suggest the electromagnetic supercharger clutch may have been changed slightly since the original GT 125KW where it doesn't seem to be as problematic. Or a slight change of design or possibly a batch of clutches causing noise problems in Golf VI TSI 118. I suspect it is in the dynamic supercharger range from approximately 2000-3500 RPM that this noise would be annoying as it can cut in and out depended on load variation at a steady speed

click TSI twincharger link

next click More efficiency link and [1] The interplay of turbocharger and compressor [2] Dynamic compressor control

then click More Power link and [1] The individual components [2] Processes when pulling away

I have read some posts where the compressor can be heard at idle, this may be the case after hard driving where the motor management system is anticipating the need for charge at idle speed, normally at idle the supercharger is off

this will give a good overview of the technology

hope this helps

That's a really cool link!

And yes... even on the website, when I press the accelerator hard in the Flash presentation I get the squeak, so it must be a feature!!
