  2. Can these problems be sorted out under warranty?
    If yes, does the service centre consider and replace the parts without any objection?

  3. If it is troubling owning the DSG, shall I go for the manual?
1. The latest software update to the DSG has solved most of the jerking issues. The gearbox now holds gear a little longer and also shifts to 1st gear in very slow crawling traffic to avoid clutch slip as well. This is definitely a good improvement. I have personally experienced this in my Polo GT TSi. However, as this was a very recent update, we have to wait and see how this improves gearbox life in the long term.

2. Even with software updates, occasionally there are some mild jerks (feels like engine braking when you shift to a lower gear). These should be considered as normal operation for the gearbox. However, in extreme cases where there is severe jerk or shudder due to gearbox or mechatronics, I believe VW covers this under warranty without any problem. I have even heard about one or two cases where they replace the mechatronics under goodwill even after warranty. The only inconvenience would be the wait for the components to arrive. My suggestion would be to go for extended warranty. That will give you 4 years of peace of mind.

3. This is something you will have to decide based on your priority. If driving pleasure is the top priority, then nothing can beat the swiftness and smoothness of the DSG gearshifts. In this case you should go ahead with the DSG. If there is an issue with the gearbox, just consider the inconvenience as a price you pay for the fun factor. However, if you want absolute peace of mind and not prepared for any trouble with the DSG, then a manual would be the way to go.

Tough decision indeed Good luck

Hello everyone!!

I have been following the threads on DSG failures closely and noticed that this still continues till date even after VW claim to have sorted out the issue with a software update or change from synthetic to mineral oil. So it is clear that there is an issue with the DQ200 gearbox which cannot be solved by VW. We all are also aware that this gearbox was recalled in China (due to pressure from customers and the Government) but the same continues to be sold here (due to lack of consumer laws) which is unfair.

Now I am a huge fan of VW & Skoda and our family owns cars only from these two brands (as seen in my signature) but I still believe VW/Skoda are getting away with providing us with an unreliable component in their cars which should not be the case. So if the DSG fails and you are inside the warranty period, you are safe; else you are doomed! It is as if VW has budgeted an amount for DSG replacements under warranty which can possibly be recovered in case there are DSG failures once the car is out of warranty or with the fact that customers opt for extended warranty.

As per the reports (on Quora - https://www.quora.com/Have-the-issue...been-fixed-now) I have read on the internet, they claim is that the DQ200 gearbox had a tendency to fail in hot and humid climates. The reason for this being; sulphur present in the synthetic oil gets deposited as conductive particles which the computer detects as a short circuit and cuts of the clutch and hence the car does not move in 'D' mode. There is also another claim that the oil should be changed every 20k kms as opposed to the 60k kms mentioned in the owner's manual. Do not know if these two points hold true.

We have 03 DSG cars in our family - the Skoda Rapid TDI, the VW Jetta TDI & the Skoda Superb TDI. Yes they are all diesels with the DQ250 gearbox which are less likely to fail but not impossible. However, there are customers and even our own team members who have cars from VW/Skoda which run on the DQ200 gearbox. Some have not had any issues at all, while others have had failures with in months of ownership. As a matter of fact, one our team members have just informed me this morning that the DSG in his VW Polo GT TSI has packed up and his car is under a year old. So if VW claims that the problem has been solved with the change of the oil or software, this DSG failure should not have happened.

So since we know that our Government is not going to do anything about VW giving the proven unreliable DQ200 gearbox to its customers in India, is it not possible that we Team-BHP members get together stand up for this cause to ensure that just like in China, VW also recalls this gearbox and/or gives it customers a permanent solution to this issue?

The Rapid DSG uses the infamous DQ200 and not the DQ250 like the other premium VW/Skoda Diesels.

Would be good to get more details on this. In general, we have not heard of too many complete failures on the Polo/Vento TSI. There have been issues related to jerks and shudders. Hence would be good to know the details on the failure mentioned above.

Oh my bad. You are right, the Rapid uses the DQ200 gearbox. All the more reason for me to be concerned in this regard.

He will be putting up a post on this soon.

Dear All,

My GT TSI is 20 months old. And in the last 1 month or so, when I am driving aggressively in S2, or S3, suddenly there is no power, there is no acceleration (nor deceleration). Its is sometimes frightening because you may be committed to an overtaking maneuver.

I am yet to discuss this with my Service Center. Btw I had gone today there for an emergency replacement of brakes. During checkup, he mentioned that there is a leak near the gearbox. So will be taking the cara again next week. Could the leak be related to the jerk?

Hi Ganesh, that is glad to know. Does it solve the kind of problem I talked in the above paragraph? or just the D3->D2 jerk? I had done 1st service in Oct 2016. Has there been a DSG update after that? Do they provide this patch only if you request?

I think this could be some other issue with the gear box. This is not the regular D3-D2 jerk. I would suggest you take the car to the service center and have them check the gear box thoroughly.

On my VW Vento 1.2 TSI Highline, I had last updated the DSG software at the VW Sevice Center had the version number: 6502. This update had served well till now. About 2-3 weeks when I had gone to the workshop for a handbrake switch issue, the Service advisor scanned my vehicle and stated that a new firmware update has come for the DSG. I told him to go about with the upgrade. The new version number was: 6551. Post the upgrade I felt the gearbox to be much smoother in gear transitions during upshifts. Even downshifts were more smoother without any jerkiness. I would recommend to go for the firmware upgrade.

It appears that VW has tweaked the gear selection logic as part of the recent DSG software update. Could this be to improve the response of the cars that were updated with the emission related fix, apart from the claimed fix for jerks felt during downshifts!

I did a 600Km highway drive today in my Vento TDI which was NOT updated with the emissions fix. The response has become even better and I love the gears holding on until higher rpms. There is power available at higher speeds and the power delivery has become more linear.

Also feel that there is slight confusion about upshifting from gears 5 to 6 and 6 to 7 at 3 digit speeds.

Overall BIG thumbs up to this update

How does a software update tweak gear ratios? The gear ratios are a given, unless you open the box and put new gears in?

Thanks Jeroen. Have updated with what I meant - removed the "ratio" which I had incorrectly used.

Since I have developed interest in understanding the DSG and its issues, (because I booked a GT TSI) stumbled upon this Quora page which I found very useful.

I am bit worried as this post quotes about oil change every 20k kms
Quote:
The manufacturers claim that a gearbox oil change is recommended around 60,000 kms or so. But in the manual it also states that if you're driving conditions are humid and also have stop start traffic one must get it done earlier. I suggest get it done every 20,000 kms. I do the same.
Last time, when I asked for the gearbox oil change for the my Polo, dealer(Mysore VW) called some expert and said Polo does not need gearbox oil change. My car is around 76K Kms, and I have not changed the gearbox oil till date.

Anybody changed the gearbox oil recently?

So what you heard from VW is correct. The DQ200 is a dry clutch gearbox. The only oil in the DQ200 is the coolant oil inside the mechatronics. The mechatronics is a sealed unit and does not require any oil change. The only time there was any need for oil change in a DQ200 was when VW recalled the gearboxes to replace synthetic oil inside the mechatronics with mineral oil.

In a wet clutch gearbox, the clutch is submerged in oil, and this is the oil that needs change every 60,000km. The DQ250 wet clutch gear box that is present in the Jetta, Octavia, Superb etc needs this oil change.

There goes down atleast 10 bookings for the VW/Skoda stable.
