TSI squeal noise problem on acceleration

[coastie]

I have the 118 TSI and upon acceleration there is a squeal noise coming from the front end. I took it to the dealer and the tech was honest and said he had just read about this problem in the GT TSI that the water pump solenoid which is associated with the supercharger clutch assembly make a squeal for a brief time when accelerating.

The tech bulletin stated there was no known fix from VW but that my warranty would not be affected if there was a problem later on?

Has anyone else had this occur. It is a June 17th Tech bulletin so just a recent problem. Mine is 5000km and 2 months old.

The squeal is driving me nuts as I now consciously listen for it. I first thought it was a brake pad not clearing but it is definitely upon acceleration and the supercharger clutch sounds more like the area,

Sure you don't have a boost leak? If one of the turbo / supercharger hoses is damaged or not sealing it can give a squealing noise.

No that would last longer this is a brief 1-2 second squeal, I've had a turbo hose leak and it's not the same. This has a metallic squeal so the clutch solenoid idea seems to point in the right direction.

This is exactly what I have going on with the acceleration squeak, the utube vision seems a bit higher in the rev range than mine and possibly associated witha gear change. Mine is a little lower in the rev range but consistent on the beginning of acceleration. As stated in original post there is a Tech Bulletin issued by VW that says they know of the problem but have no fix. I would like to see how Burwin got the replacement waterpump through as my VW dealer won't attempt anything until it is authorised as they won't be reimbursed by VW for the replacement part.

Thanks for the help.

Is this a widespread problem? Is there anyone with a 118TSI that does NOT have this problem?

I don't want to believe, but it seems a common problem on MKVI 118TSI now. Although I am still waiting for my new golf, I am so worried about this problem.

What I'm surprised with is that I haven't noticed any reports of this problem on Mk Vs even though this engine originated on the Mk V as the GT.

Its seems to afflict the Scirocco and the Mk VI. Perhaps there's a batch or change in spec in the magnetic clutch.

I have written to VW to seek a response about addressing this annoying problem but I am still waiting. My dealer won't go any further referring constantly to the Tech bulletin from VW stating it won't harm the vehicle or affect my warranty claims. this is not good enough IMO. The noise comes from something that is not correct but they won't look for the problem.

Its totally understandable......Its not only the point that it won't harm the vehicle or affect warranty claims, you paid premium coin for a car that was stated/advertised as having superior refinement and noise suppression. Really... what is the point of suppressing wind noise, tire noise and engine noise when its just been replaced with a noise "screech" even more so unbearable instead.

The dealer knows this and so does VW. Good on you for making noise, keep at them, they have to be held accountable.

VW Australia have responded very quickly and have requested I return vehicle for full inspection to address my problems. Have to wait 2 weeks for the loan car to be available so the saga continues. Thanks Dermot for the suggestion, it may just be that simple, I just don't like the initial response that there is nothing we can do at the moment.

[chylld]

I think Dermot's reply will prove to be very helpful in fixing this issue. I know when I get my 118TSI, if it has the problem I'll be going straight to the dealer and say "the guy at Wangara Volkswagen fixed this same problem before, and it was just a pully that needed lubricating."

Dermot: are you able to say which pully exactly?
