thats usually the 2nd -1st downchange which ive found noticable in nearly every DSG ive driven

I thought that might be the case. Thanks. It could also be that the dsg oil is gettng old 3yrs old car. Or that it needs an adaptation. Cheers.

Could be both of these things contributing actually. I've heard a case recently of a car repeatedly jolting and lurching when it drops from 2nd to 1st gear in traffic, which has been (understandably) causing the owner some grief. I'd say that in the majority of cases a DSG reset + adaption will do the job, and that it's simply down to the DSG getting the clutch pressures wrong on that change, but many 2010 cars are coming due for their 60,000/4yr DSG service and oil change soon too, and old oil may be contributing in its own way.

Ok guys I am a newbie (I've only owned my 2012 Golf 103TDI for a year now) so admittedly I don't know a great deal about the DSG but one thing has been bugging me: Sometimes when I drive my car on a flat road (usually first thing in the morning) and steadily accelerate from 4th to 5th gears at about 50km/h, the car momentarily hesitates to change into 5th gear and briefly shudders/jolts a few times before switching into 5th. For some reason it only happens when going from 4th to 5th or when cruising on 4th. Do you guys think there is a problem with my DSG/mechatronics unit?

Forgot to add that I've told VW about this prob and they keep 'assuring' me that's its normal for the DSG and end up resetting it. I kicked up a stink at my last service because it kept happening so the techs took it out for a test drive. Of course they didn't find anything wrong with it and told me they couldn't do anything if they couldn't see the problem first hand. They even said it'd be better to let it get worse before bringing it in again. My only concern is that I'm halfway through my warranty already so if the DSG dies after it expires, I'll be up for a ****load of cash. Any advice?

I'd say it doesn't matter - the problem has begun in the warranty period... Just because it's intermittent and they can't reproduce it, doesn't mean they don't have to fix it if they can finally reproduce it out of the warranty period..

Correct. rossv, just make sure your dealer has made a note of the issue (if not already; get them to check it and have them note the fault on the paperwork for your next service), and then you should be fine.

My gti is Nov10 built and a few weeks ago at 28,000km I had the dsg fluid replaced at Mike Webber Prestige n Performance.

Before the change I had minimal issues, like rather loud clunk when selecting dsg mode at stationary, fluid leak over time tru the pressure valve cap and clutch slip once. Also launch ctrl used 8 times max since new on the 1/4m strip.

I remember watching Best Motoring show on youtube, the owner of Spoon (Honda famous tuner) said that gearbox oil actually gets worked out as harsh as engine oil. Yet engine oil is changed frequently but gearbox is often neglected.

After the fluid change, OMG car has been running smoothly like new!!

......any 2010 cars are coming due for their 60,000/4yr DSG service and oil change soon too, and old oil may be contributing in its own way.

This car had had its mechatronics replaced in February however, would that have involved a reset etc? Either way VW showed no interest in dealing with this issue.

(I know the car that was test driven.. I'd owned it for three years )

Aaaah. So if the mechatronic has been replaced within a few months, maybe it's just had many drivers and an inconsistent learning regime, in which case it's got itself a bit out of whack.

I believe that a mechatronic replacement necessitates an oil change (can someone confirm this)? I know that oil flows near or through it (the thing's full of solenoids and actuators and so on), so you would think so.

Except that the car displayed the problem described before the mechatronic replacement, and after.. and as you know the car was treated with care.

The only thing I can't vouch for is the gap in the mileage between when I traded the car and when thezoneR32 went for his drive (around 300-400km).

However the issue described sounded similar to the one that was driving me nuts as well. On the plus side the problem didn't appear to worsen and I never got any false neutrals or any other odd behaviour. I now completely understand the love/hate thing with the gearbox and the car itself that others have reported over the years.

I don't believe in this mechatronic unit learning from different drivers thing. Is this really true? Is this stated in any VW document anywhere? Really curious.

I have seen differences depending on if accelerating up a hill the car will hold a gear longer as it knows it is on an incline but that's about it in terms of "awareness".

When I scanned your car and checked for the software updates, there was one for the DSG. So, the dealer should update it for free, when it was still under the warranty, otherwise I charge just for the time taken for those software updates.

Correct - they showed as much interest in updating that as they did with my other DSG issues (ie. none). I had to speak to four different people to explain that the cars even had software updates from time to time.

Which is why I was surprised they didn't even flinch at doing the mechatronics.. perhaps easy money for them on charge-back to HQ.

Be interested to see if whoever bought the car pops up on the forum here at some point.

I had my 60, 000km service done on Monday, with the DSG service and oil change. It has made a vast improvement to the smoothness and refinement of the gearbox operation, particularly at low speeds. I didn't even notice there was anything really wrong with it prior to the service but can definitely notice a substantial improvement now.
