TSI squeal noise problem on acceleration

[soogs]

The supercharger runs off a belt which is attached to the water pump pully so the clutch cuts in when needed for supercharging hearing the squeak. So the the waterpump pulley is attache to the supercharger clutch being the same item. Has anyone ever heard on older cars the AC compressor cutting in a very similar noise. To the S/charger squeak.

Yeah my old Honda used to do that when you first turn the aircon on. It was only at start up and also only intermittent. I blamed it on a slippery belt at start up, but that wouldn't explain it happening to a new supercharger would it?

damn!! It's back. After a 4000km break with the replacement supercharger clutch, a small squek has reared its ugly head.

Oh well, sigh, wait for VW to present a permanent fix.

Over the past week I have been fortunate enough to first drive a 103 TDI DSG with ACC and today a TSI 118 DSG with ACC. In both cases I covered suburban, freeway and highway driving and I've got to say both cars exhibit a smoothness and quietness to the point where it's hard to choose between the two. The TSI is quieter off the mark but both are super smooth and quiet at speed. In terms of economy I found the TDI approximately 1-1.5 L per 100K better than the TSI but the TSI has a slight performance edge which is a trade off for the TDI economy. In the TDI a run to Wollongong and back including suburban traffic I averaged 4.8L per 100K and short trips around town sometimes with the engine not fully warm averaged 7L per 100K. I specifically wanted to compare the two because of the squeal-chirp reported in some TSIs the TSI I drove has done over 4000K and in 250K I heard it a couple of times but unless you were specifically aware of the squeal-chirp I dare say most people wouldn't even notice it. I noticed in normal driving the engine rarely gets to the rev range where supercharger will cut back in. Most of the time around town the engine is only running around 1100-1500 rpm with seven gears and so much torque from the supercharger which is on permanently up to 2000 rpm obviously there will be no squeal-chirp in this rev range. I found the DSG a tremendous gearbox in both cases TDI 6 and TSI 7 speed, the DSG is intuitive selecting lower gears for engine breaking even in D mode but the speed and smoothness of changes impressed in both. So I'm stuck with the choice of ultimate economy of the TDI or a high tech TSI with the possibility of the occasional squeal-chirp which from what I can see is probably only noticed because the car is so smooth and quiet anyway. I've got to say the TSI is a technological marvel almost turbine like in its power delivery and smoothness. The ACC is also a great option sport on the freeway if only for the sharpness of the steering, I found the ride good in all modes, you would only need comfort mode on the worst of roads and I guess we do have plenty of them. Anyway that's my experience of the two Golf's.

Does anyone have ticking noise from somewhere behind steering wheel? I found this noise these days and it comes all the time unless deadly flat road.

After 2 months 3000 km squealing noise is back,
Next week I am going back to VW dealer.

One dealer replaced w/pump after 4000 km because of noise… noise was back after 2 weeks
Other dealer cleaned and lubricated something and it was OK for 2 months and 3000 km… Next week I am going back to second dealer
I am not sure what was lubricated (I am not technical person and after reading some comments – I am concern) especially when I saw somebody indicated that VW is advising against lubrication - warranty issue.
If anybody is having information what should not be lubricated according to VW, can You please, give me more details...I need them before going back to VW dealership next week

Thank You

Hey ox, I've noticed this as well sometimes. For me it is the badge on the steering wheel, like the adhesive keeping the badge on is settling or something, mostly only here it on hot days. If you push the badge you might here it a bit...

An unofficial update from the VW service center, there will be a new lubricant coming out to resolve the gear change noise issue..don't know when though.

I think mine is from inside behind MFD or Steering Wheel, anyway, I have booked in next Thurs, let you know the results.

That's a really good news~~

I solved all of my issues by buying a new car from a different manufacturer. So glad that my Golf will be out of my life in a matter of days.

Soon to be ex owner of Golf 118TSI DSG Sports pack.
