TSI squeal noise problem on acceleration

[Guest]

There is a new water pump/magnetic clutch with a different friction lining that does not make the noise they have been testing it now it has gone out to be fitted to the cars with the noise

I actually had an update last Friday when I picked up my car from service. I thought not to post and raise excitement unnecessarily because it seems like we keep hearing about updates for fix release only to find nothing tangible is happening to aussie 118TSI owners.

Since you’ve made the post, I thought may as well share what I have.

Last week VW five dock service centre received written notice from VW that they will be sending parts out and be engaging in a recall campaign for affected VINs. As usual, no timeframe was given on when the parts would be delivered nor when the mailout will be done. They know that it’s a fair number of vehicles that will be affected.

It is probably just the friction material that they USED to use on the Golf GT and GT sport.

No mk5's suffer from the squeel as far as I am aware. Anyone know of any mk5's with the issue?

i rather enjoy hearing a squirrel yelp every so often when i accelerate!!!



but seriously.. does it affect performance? and aside from the noise being annoying to some people - is it damaging any other parts in any way?

Polar--> didn't you mean MK6's are not affected?

i thought it was a common trait/idiosyncrasy of both mk5 GT/GT Sport and 118tsi?

My wife's GT Sport doesn't do it. You just hear the supercharger click in (getting ready for action ??) when you put your foot on the clutch.

From reading the Erwin SSP for the 1.4TSI, the supercharger is engaged a fair bit of the time. Perhaps in the Mk6 VW have changed the engagement strategy in a bid for better economy which has resulted in the cuurent woes.

That's interesting. I've always wanted to know what the real differences were between the two generations of engine. This has given a bit of insight.

From observing the cars telemetry I can tell you that it isn't. The supercharger engages very briefly but quite frequently. Without looking back at my notes I recall it typically engages for between 2 to 3 seconds which to my way of thinking is not at all a fair bit of the time. Be interesting to know what the minimum torque requirement to engage the S/Charger below 2400rev is, because it certainly does not run anywhere near all the time in that rev range.
Perhaps VW changed the friction material in the mag clutch simply to increase its life which would be kind of ironic for them.

Yes, and the dealer knows a few others.

I'm having the above work done next Monday.

I think he was making the comment in relation to the MkV TSI

hey hey... this is new. Which dealer? Did you specifically receive the recall letter?

It's not a recall. I had the issue intermittently and then it comes back for about 5 weeks and goes away. Dealer lubricated the clutch and the noise went away for 6 or so months, then again came back on.

Dealer then basically said (this was before Christmas) that they'll replace it with the new design.
