TSI squeal noise problem on acceleration

[MorganTSI118]

Gen 5 golf

I am pretty sure the car has done around 110,00km. WHich would also make it out of the 100,000 warranty (if the car wasn't already 4 years old). At the moment my dad is trying to be patient but they have come back and suggested that they can replace something else that controls the DSG (Sorry im not up with the technical names)... it is some computer part. THey said it will cost him around 2500 instead of the 11,000. However my dad has read things online where the DSG has still failed after this part has been fitted. Im pretty sure he wants to just pay for it and get rid of the car! He is pissed!!! I would be fighting it as well. I will show them the link and see how they go Thanks!.

As for the squeal - it has only been noticeable since the new cars are just soo quiet. I just wish they had done something about the cars in europe before sending them to Australia, as I am sure someone would have noticed in that time.

[QUOTE=Tommy;376484]The TSI engine has been around for about 4 years in the form of the GT, you would think that all issues with it would have been ironed out by now? I'm also confused as to what exactly this problem is. Some people have been told its the supercharger clutch, others have been told its the water pump and others have offered completely different explanations/theories. I'm beginning to think that VW doesn't have a clue? Why has it taken VW 4 years to come up with a 'fix', this would support my notion that they are clueless?

The DSG was replaced in my car a few weeks ago at 2500kms and the chirp seems to have largely disappeared, I have only heard it a couple of times since. This kind of suggests to me that the issue may have something to do with the clutch mechanism.

Am fairly keen to get the new 118TSI in the future but all these negative comments are putting me off. Interestingly, there aren't many posts in Uk forums compalining about problems with MkVI. Their posts are mainly comestic ones.

With the squel, is it the twincharger motor, the DSG or a combination of both. The DSG is also available in the diesel. Do they have the same problems? Like you mentioned, even VW has no idea.

It's one in the same thing. The clutch and waterpump are connected together (probably the same pulley). Sorry for the confusion.

I've had the same experience as you Tommy. I had a Mark V Comfortline 2.0 FSI and that had tons of issues.

I also agree that it's strange that we're seeing the issues & we should have expected them to have been ironed out in Europe before the batch of cars delivered to Oz.

The DSG gearbox has nothing to do with it due to the fact it happens on manual gearbox's too!
Also Golf V GT had 6 speed DSG's where as the Golf VI has the 7 speed DSG totally different gearbox's.

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.

TDI and TSI test drives looking for the squeal-chirp

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~~

All Issues Solved

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.
