| re: VW Polo / Vento DSG: Gearbox Jerking Issue! EDIT: now resolved! A bit of technical info as follows: The clutches and gearbox units in the DSG are operated hydraulically. This function is performed by the gearbox mechatronics module, housed in the DSG. Obviously you need lubrication for smooth functioning of these units, there is fluids in Mechantronics and in Gearbox. The issue here is VW have been using synthetic oil in their DSG. The synthetic oil has sulphur constituents and can separate off during hot and humid conditions. Remember Chemistry and then "electrolysis". What happens after separation is that this sulphur settles between the conductor path of electronics in the form of conductive particles. Well the SMART computer/software in the DSG then thinks that there is a short circuit in the system and releases the clutch to open mode. This false open means that your gears are not engaged and therefore you get no drive. This is known to be the cause of the problem. The occurrence of this is increased in particular if the vehicle is subject to hot and humid climate, coupled with a high proportion of stop and go driving (perfect conditions in India, right). It is complete nonsense for the dealers to say they are unaware of this problem. Every model in VW line from Skoda, Jetta, Golf, Polo, Amarok have all been recalled due to this issue. One of the many things they have done is (a) to use mineral oil or change oils in DSG or (b) replace the whole DSG followed by a software update. I am no expert in this, but see from your manual whether the fluid used is G-052-512-A2 (this is mineral oil) or G-052-171-A2 (synthetic oil). This video is what you guys are worried about: |

| re: VW Polo / Vento DSG: Gearbox Jerking Issue! EDIT: now resolved! Sorry if this is a newbie question but wouldn't such issues be covered by the VW warranty? I was happily dreaming of owning a GT TSI and this thread happens :( |

| re: VW Polo / Vento DSG: Gearbox Jerking Issue! EDIT: now resolved! Just spoke to my friend who picked up a Black Vento TDI DSG on the 4th of this month from Chinchwad for a whopping 13.8 Lacs on road! After going through this thread i asked my friend so what instructions did the showroom guys give you? His(SE) reply was "Nothing sir , just drive any how you want, our engine doesn't even need the running in period , oil changes only after every 20,000k kms or just once a year,Congratulations sir". No mention of DSG care anywhere. On hearing his my friend too happily drove to Kolhapur the same day and back next day at high speeds! ![]() I was shocked to know this! ![]() Is it true that VW engines do not need the running in thing ? Mod Note : Team-BHP strongly discourages unsafe driving practices that put yourself and other road users at risk. Please do NOT post about illegally high speeds on public roads.

When I took delivery of my gt tdi , those were the exact words my SE told me. " Sir, you can drive however you want, our Vento customers rocket themselves out of the dealership after taking delivery". I nodded. Then after a few seconds he said, "no need to worry sir, if anything happens at all your warranty will cover it". After he said that we smiled at each other while I said to myself, no thanks Mr wise guy, I'm taking this one slow and steady. ![]() Last edited by Gannu_1 : 10th May 2015 at 16:27.

| Apologies for the lengthy posts. I'm a writer actually and only mildly active on forums and therefore I often go into "story writing mode", so apologies for that again. Quote:

The way the DSG gearbox works is simple. When in "D" mode, and there is a sharp jab on the accelerator pedal, the ECU detects the urgent need of power and downshifts, sometimes skipping as many as 3 gears. This will result in a "single" jerk, and that is normal and to be expected from most automatics. The issue I am referring to is a bit different from the hard acceleration one. My car stays within the same gear, and yet jerks a few times without downshifting. If what you are referring to is the same, then I guess you have the same problem as me. If it is the former issue, then don't worry, thats normal. Quote:

They do have a manual TSI in the Jetta if you can push your segment higher. Quote:
The second point was a thing that has plagued all the DSG 7-Speed boxes, and I knew about it before I purchased the car - so didn't mind that too much. But now I'm kind of apprehensive since my brothers been driving a friend's Polo GT TSI, and he says the 3 to 2 jerk doesn't occur in that at all. Also, there's almost no way VW is going to take responsibility for this issue, since admitting the gearbox is faulty since manufacturing will have to result in them recalling the cars they've already sold - and recalls on that scale are a slim possibility in India.

Like I've mentioned above in my reply to rahulsharma - what you are describing is normal and not the same issue I'm referring to here. Don't worry about it too much. Quote:
Put the key in the car, turn it to neutral - Do Not Start the engine. Turn your bluetooth on, try connecting and playing something. If it starts playing, your good to start the ignition. IF it does not, turn the car off, remove the key, wait for 10 seconds, and try the whole process again. Once it connects, it does not disconnect until you remove the key. So keep the key inside when taking a short break or refuelling. I gave them all the points related to safety etc. since I was temporarily using an AUX input for connections, but without call receiving and track changes, the multi-function steering was not multi function anymore. I made at least 4 videos to show them also. And even got an official reply from a technical guy telling me that "VW only supports Nokia phones, since the bluetooth Nokia uses is different." Can you imagine that?! I mean I can understand a service advisor giving me crap like that, but TECHNICAL guy, who's supposed to have specialised in this stuff? Quote:
I've already posted the link to your thread when I last forwarded my complaint to the plant technical guy last week. And yes, it is certainly scary and terribly dangerous. Quote:

I took delivery of my Skoda Rapid elegance plus DSG on 2nd April from Tafe Access Bangalore. Even my SA told exactly the samething about engine run-in. The next day i drove to NILGIRIS as it was a long weekend. But i drove below 105kmph. Seeing this thread now gives me jitters. The odo is at 1800kms now. I will be closely following this thread now and will also get the gearbox oil checked at 5000kms. Is there anyway to check the gearbox oil level without going to the service center?? | |

| re: VW Polo / Vento DSG: Gearbox Jerking Issue! EDIT: now resolved! With due respect to ahmadnaik for what is a genuine problem, let's please not jump the gun here. There are a lot of Polo/Vento TSI owners on this forum who haven't experienced such issues -other than the downshifting thing, which in my case has gone away to be replaced by an occasional clunking/thumping mechanical sound. As others have pointed out, the fault may lie with an entirely different component. Let's please wait before pronouncing this a return of the dreaded DSG issue. If I remember correctly, the DSG issue left many stranded with an unresponsive gearbox - that hasn't happened here. Also, the Australia case mentioned here was not DSG-related. That was a manual Golf. |

I feel bad for what you are going through. A car losing power at a critical juncture is every driver's worst nightmare. I own a 2013 Polo TSI GT, which has done 12500kms and been a dream to own. I have no major issues with the Car and none at all with respect to DSG. Yes, the D3 to D2 jerk was very prominent before, but since 2014 oil swap and some software fix, the jerk is much less. So much is the faith in the car that I have made the move to throw away the money I paid for extended warranty and get certain mods done on the car. ![]() However, I would advise you to proof read your posts before publishing, especially when you start a thread where opinions could be polarised against a good product or make people question OP's credibility. I am raising this point, because nowhere in your OP, you have mentioned which VW product you own. Since you have mentioned MidnightBlue and first car in Mumbai in October 2013, I had to assume it is the Vento Tsi DSG you are talking about. To other members, Please don't jump the gun and kill the DSG already. This is the first DSG case amongst the 1.2TSI engine, yes definitely one can't ignore it but there are thousands of other cars out there running without any issue. There are members thrashing the same machines on track days, doing the bumper to bumper office runs and have done similar mileage to OP. So have faith. I sincerely hope that @ahmadnaik's issue is resolved to his best satisfaction by Volkswagen India. Cheers, D. | |

Like I mentioned above- I'm a little new to being an active member of Team BHP, so hopefully after a few more posts I should get familiar with the rules and nuances of posting and starting threads without errors. So, I apologise for not mentioning the Vento TSI - it is most certainly a gross oversight on my part. Now about the opinionated post - I've mentioned quite clearly on multiple occasions in my posts that "I still love the car". I've also mentioned that despite this issue, I have acknowledged in my post that for the first 30,000 kms it was smooth as heaven. Unbeatable in fact, and most definitely the best in the segment. My only qualm with VW is not with their cars, but rather with their lackadaisical attitude towards their customers. The quality of the vehicle is unmatched and despite my recent negative experience- I will probably continue to buy German cars (as long as I can afford them) as a personal preference. I have been co-operating with all their requests for the past 3 months- despite them never offering to pick up or drop the car when the issue continued to persist in the beginning. My brother has been spending loads of money on taxi trips to work when the car was not available, and yet I was willing to cooperate as long as I felt that VW was moving in a solution based direction. It is only after numerous failed attempts to explain my issue adequately and VW continuing to brush it off as though it's not serious have I resorted to Team BHP for this post. Perhaps it was a little strongly worded - but it was also an honest complain by a genuine VW customer. P.S. - Thanks for the corrections though, really appreciate it.

| re: VW Polo / Vento DSG: Gearbox Jerking Issue! EDIT: now resolved! I don't quite see why VW should be spared from blame on such issues? From the start they've had problems with the "DSG" boxes, be it complete failure or jerking/poor performance. We don't even know how many owners are there who haven't taken the DSG issues public so we can't assume the ratio of vehicles affected yet. This is far from so called "quality". Worse yet as usual the service centre is playing its old tricks of keeping the vehicle in the garage promising results but coming up with zero explanations & repair. People pay the company specific, specialized mech personnel the additional premium for what? They might as well put their tongue out & say "Duhhh I dunno". I've also seen some real dunces in Hyundai service who wouldn't know a nut from a bolt but atleast the issues were small & I troubleshoot them myself. From the start VW has been playing hide & seek with warranty terms, do they think the extended warranty rate/standard warranty included in ex-showroom price is additional profits? How about replacing the whole DSG free of cost if they don't "understand" what's wrong? This is purely a factory defect. To me there is no excuse for quality, if DSG doesn't have it then scrap it altogether. Perfection is internal components working seamlessly with external body shell, not just the shell. |

The EGR is located behind the engine in the Polo. I am not very sure if its the same with the Jetta. Please ask the service centre guys to check this. You'll have to speak to them again about the warranty (assuming the EGR valve needs to be replaced-Since I had the EGR valve cleaned, I am assuming it can be cleaned in your car as well) |

BTW, sorry if its mentioned in the thread and I missed it, but is the car still under warranty? There simply isn't an excuse for VW to treat you in this manner if it still is. | |
