View Full Version : Possible DSG Mechatronic Issues

I have completely got the hang of the dsg now. Very comfortable with it. I am also driving a lot more in manual mode, which is quite fun.
I have been reading some horror stories on mkv.com from dubbers with dsg issues. As I have about 18months of warranty left I need to make sure that mine is fine. It seems that one of the symptoms of a failing mechatronics unit is a surge forward on shift down. Now in manual mode when I shift down, the car does tend to surge a little but it’s really subtle and to me it just seems like the gear box is expecting you to floor it when you shift down. To give an example: when coming down a hill if I shift down expecting the lower gears to slow me down the instant action is that it tends to speed up as though it’s expecting me to floor it. Not sure if this makes sense. I really need to hook up with someone who also has dsg. Maybe I should just waltz into vw and ask to test drive a new dsg equipped golf. I feel that if take the car to vw service for diagnosis that I wont be getting an unbiased opinion.

Be careful of what you read. People who write to complain about their DSG are only ever in the minority. There are a million of these gearboxes running around the world and you never hear the good stories.
If you're concerned about your DSG's behaviour, take it to VW service to have it diagnosed. It costs nothing and they may very well reset it for you.
If you bought your car second hand, chances are good the fuzzy logic has kept its previous owner's driving style which (as the service advisor so eloquently put last week to me) "[It] tries to remember the way it thinks it is meant to drive."
I had my DSG reset and now seems be better, but it won't last long, because my wife also drives the car, and the DSG tries to accomodate her driving style too.
It's a clever gearbox.
Agreed, out of the loads of Dsg coupled cars ive looked at ive had 2 with dramas and one of them was cooler related. To have the gearbox fully reset, it takes a procedure about a page long to do so. Step by step must be right or you have to start over, so yeah very clever trans, Porsche now use it called PDK which is Porsche Doppelkupplung which means Double clutch in German.

The car blips the throttle when you downshift the DSG in manual mode.
The surge you are feeling is not the mechatronics failing, it's the throttle blip.
90% of the time I find it best to slow down with the brake and let the DSG shift itself down when in manual mode.

. . . let the DSG shift itself down when in manual mode.
And this is not a bad tip. In manual mode, the DSG doesn't have to think about shifting up, so it can concentrate on shifting down smoothly.

Thanks guys. Sounds like mine is fine then. Not sure about the shift down yet. I need to get used to it. Especially when slowing to a sharp corner and you need second gear it seems to take too long to decide on 2nd whereas I find I can shift there myself quickly. Maybe I should trust it more. I will need more practice.:rolleyes:

That's the 1% occasion...:)
And where the blip/surge is most evident.
Best way I've found for this situation is to anticipate, and get into the correct gear early - it means using lots of revs but revs never hurt a VW mill.

I second that... if you are getting it on, even S mode can't adequately pre-empt what gear you want in many instances. Whack it in manual mode, and set yourself up with the right gear BEFORE the corner, not wait for the DSG to pick it when you get power on coming OUT of the corner.

Does the DSG downshift automatically in manual mode? That's amazing!

Yes it does, but it waits until the revs get pretty low.

The only way to do a fair comparison is to find a DSG equipped R32 which the dealer won't have. Testing driving a Mark VI TDI with DSG is no comparison.

Why would VW service lie to you like you're insinuating? If you take that attitude with the dealer don't expect them to offer you much in the way of help. I wouldn't be taking the car in complaining about problems unless I was sure that it was a problem first.
You only just purchased the car last week, why don't you get used it before imagining problems and making modifications :confused:

That is good advice. Timing is the issue here, if you drop down too early it revs its guts out which doesn't make for a smooth ride, the other issue is knowing hat gear you are in as you approach. May just take time but I find that i lose count after a while and need to look at the display which is a bit small and not as obvious as I would like. If I'm driving in a spirited fashion in manual mode theres a good chance I'm coming into the corner at speed and I have to take my eyes off the road to find the display and check which gear I'm in so I don't accidentally change down into 1st (done this only once!):mad:
The gearbox is a great idea I just need more practice with it. Its a pity you cant display which gear you are in in the MFD in large font! That would be awsome!

I'm not imagining problems. I'm merely making sure they are not problems. The vwvortex forum people with dsg issues say that vw technicians will not diagnose the problem unless you bring it to their attention and force the issue. I would hate to get out of warranty and then find out that this little issue is a big one. Turns out it probably no issue at all. So thanks for your help people.
On the issue of vw service. I have had one interesting encounter with them which does not give me much confidence.
When I transferred the rego I bought a pair of Euro style number plates, which I was told had to be fitted within 24 hours. Being so ridiculously busy at work I decide to drop in to Solitaire vw and ask if they could fit me in. They did at short notice which is great and said that it would only take 10-15 mins but it took almost an hour. When the car came out the plates were fitted but were skewed quite heavily to one side! I pointed out to the service manager that they should be in the middle, something I thought would have been pretty obvious. He agreed and now they are ordering a new pair (at their expense) and will have to ref-it them! Not inspiring service imo.
I’d rather go to the small specialist mechanics for my servicing needs. Where you can actually talk to the person who will be working on your car and who actually cares about attention to detail!
Sorry about the rant!

Why do you need to look to see what gear you're in? The sound of the engine should tell you this and the car will only let you change into 1st if the revs are low enough so I don't see a problem with this given the fast gear changes allowing you to change gear in the corner. Plus the car will change up or down a gear if required before any damage occurs.

Spend more time driving the car rather than self diagnosing problems. Pretty much every post you've made so far has been about problems with the DSG, the headunit, flashing the car, suspension, tyres.... most of which could have been answered at least partially by using the search function.
If you're worried about the DSG buy the extended warranty for around $1400, gives you 3 years additional parts and labour.

As for the servicing you can take it where-ever you like but don't expect the small mechanic to have access to the equipment nor the information nor the support that the dealers have. From a warranty perspective getting the car serviced at the same place where you get warranty work is less hassle, you won't have any finger-pointing and they'll be more inclined to honor warranty claims that are borderline.

It can happen even with a manual in the really twisty fast slow stuff so I could see how it could happen with dsg. And our cars arnt the noisiest out there and quite easily drowned out if driving in a pack.

If I never took my car to the dealer I would have had 1 warranty claim instead of many.. Also had damage caused by a dealer when doing a warranty claim then later to be refused warranty on the damage that they had caused..
Piece of mind knowing that someone skilled and experienced is actually working on my car far outweighs any issues you may have with warranty claims IMO. I remember when I was 14 on work experience and I stripped out 5 of 6 spark plugs on a new xr6 at a ford dealership. The guy just shrugged his shoulders and said **** happens.

I can see why it would be important in a manual although you would know if you're changing into 2nd or 1st as they're in different locations but on the DSG it won't change down in manual mode unless it's safe to change and if you plant it midway through the corner in 1st it'll change at the redline so no risk of any damage and because the change is so quick it won't upset the car.

Some dealers are shocking, I've had good experience with Highway so far and with two other dealers on the northside now hopefully Austral will lift their act (although after seeing some of the problems from the last few weeks they doesn't seem likely).

ok yeah gotcha.. would very very rarely change down to first anyway as the GTI has plenty of torque to pull through the slowest of corners, only really do it if actually stopped..Normally just fry up in 1st aswell anyway..
Dunno how much truth is in it but have been told that forcing a downchange to first in dsg at anything above 20ks or so is a bit of a no no.. same goes for manuals I guess anyway..

No, it's not a private forum, but there is a happy medium to be found in searching first, then asking questions. Most forums suggest STF - "search the forums" first. Whilst the questions may be new to you, forum regulars (who do this for love, not for personal benefit) often end up answering the same questions over and over again. Saying that you don't have time to sift through endless possible answers, perhaps you should consider that others may not then take the time to answer your questions. :D
Whilst that may not be the case in this specific instance, it is still considered good forum etiquette to search before posting...

I've answered a number of your questions so far and even though I've provided links (directly to the information) you've kept asking questions rather than read through the information. A lot of your questions are very vague and you're not sure what you want (having only had the car 5 minutes) hence my suggestion that you spend some time driving the car.
As swallowtail said everyone is happy to help but many people won't bother responding to your threads (especially after you've shown a number of times that you're too busy to do your own legwork) and you'll miss out on a lot of good information and opinions because you haven't spent some time researching yourself.
Up to you, you can keep creating new threads and learn limited amounts or read and ask a questions on older threads and learn a lot more.

The only quib I have about the dsg is low speed down shift.
Try this:
Cruise in 4th or 5th in M mode
Shift down a gear and then accelerate (do this quickly but in that order)
I find I get a rather long lag where I have no drive until the next gear is engaged.
This is where it gets me, cruising along in traffic in 4th, see a gap in traffic and wish to change lane. Shift down, accelerate, and at the same time pull out into the next lane, and I get no power! Not fun when if you cars coming through on the other lane.
Now try this second test:
Cruise in 4th or 5th in M mode
Accelerate first, and THEN shift down a gear. It's almost instantaneous.
So the lesson learnt is get into the right gear before you do what you want to do, be it lane changes or 2nd gear hairpin corner.

DSG allows you to change in the corner because it changes so quickly. This is often mentioned in the reviews as they have the ability to change gears in the corners without unsettling the car.

This may be so, but my experience in the TDI would indicate that in some circumstances the mid-corner gear change and consequent change in torque does unsettle the car. Having said that, the DSG is extremely competent and smart enough in D or S mode not to pull a stunt like that, anyway.

Why? The reasons for not changing mod corner are no longer valid with a DSG, there is no interruption to power and the car will not become unsettled. If the car can safely change gears mid corner and this gives it an advantage why not use it?

maybe not in a 32 and not so much on a ko3 either but if you're in a higher gear changing down into a peaky powerband would unsettle the car

That would be because you have a tractor, you barely notice any interruption in power delivery on the GTI.

The DSG changes at the same speed no matter what it's connected to. If the TDI feels sluggish between gears (like the one I drove today) than I don't think it's unreasonable to make that assumption :confused:

Except it does. Both engines have different characteristics and this affects the DSG operation, I assume that's it's down to torque, speed of the engines etc.

"Having spent extensive time in both a GTI DSG and my car (TDI DSG), I'd say that the DSG coupled to the 2.0T in the GTI definitely shifts faster. But, it also shifts differently. It's hard to explain, but it just shifts differently compared to my TDI."

I'd rather wear out a set of brake pads than using the transmission for braking, much cheaper and unless you're a competitive racer it's probably not necessary.
Also if the corner is tight you can't really use the paddles and while you are playing with the gear lever its a lot like manual and i'd rather concentrate on the line and power out of the corner.
DSG would be good for down changes though, I tend not to rush manual down changes to look after the clutch/box.

I found the DSG a bit sluggish on the MK6 TSI I got as a loan car, but expect the GTI to be much better.

We're not talking about engine braking but being able to go into a corner in one gear and exit in another to maximise the speed through the corner.

Downchanging at speed right before or during a corner sounds like engine braking to me unless you are talking about changing to a lower gear out of the corner.

I'm with the school of thought that you get into the right gear before the corner. Concentrate on trail braking and steering. If you find you need to change down a gear mid corner, you've gone in too fast and in the wrong gear. (or the "corner" is actually two corners) On some corner, you may short shift mid corner and change up earlier when the corner opens up.
Just because the dsg can shift down smoothly, doesn't mean the driver should be lazy and fumble with gears in the mist of trail braking and steering. F1 is a good example, watch some in car footage and listen to the gear changes, they go flat chat until they hit the brakes and then shift down the gears quickly, all before they even turn the wheel.

If I'm not mistaken the whole reason for not changing gear in a corner (and this only applies when you're driving on or close to the limit) was so you didn't unsettle the car and fly off into the bushes/trees/spectators and this can occur in a number of ways.
Changing down gears in a manual car and letting the clutch out too soon which results in both lack of drive for a short period and rapid weight transfer to the front wheels or changing up and interrupting power to the wheels.
Weight transfer through agressive steering, braking, acceleration or gear changes.
The DSG addresses all of these issues (except the steering and braking), gear changes up or down don't upset the balance of the car and the changes are so quick the engine speed changes only by a small amount.
Just because something wasn't recommended in the past doesn't mean that it can't be performed now when there is a solution to the problem.

I got the impression you were talking about downshifting mid corner. Although you can with dsg, it's not the way you should drive but maybe ask a performance driving school.
Actually back when I did my driving licence you'd get a fail if you are fumbling around with gears or touching the clutch pedal after you've entered the corner. Not sure how they teach now but seem to be a lot of bad drivers around (in general).

You are correct, dsg helps ordinary drivers achieve smooth gear changes. Which means less chance of locking up a wheel, unsettling a car etc. However, a good manual driver can also do the same without unsettling the car by matching revs and car speed. It really has more to do with simplifying your driving than unsettling the car. You get in the right gear early, you have one less thing to worry about.
It depends on the type of driving and surface condition. If you ask a circuit racer and then a rally driver, they will tell you different things, because they have to deal with different driving conditions. Circuit driving tends to follow a recipe. Road rallies have more thinking on your feet, but still, if you know what a corner is coming up, I doubt many good driver would brake, turn, and then down shift to the gear before exit. You need to be on the power as soon as you hit the apex so when do you have time to down shift?
Then again what I'm talking about is optimal spirited driving where things happen real quick. Real world pedestrian driving? Do what ever you like.

DSG allows you to change in the corner because it changes so quickly. This is often mentioned in the reviews as they have the ability to change gears in the corners without unsettling the car.
After my drive yesterday in the new GTI, I'd have to say that the DSG would have had to have been changing down in mid-corner after my run down the straight. Braking hard into the corner, I was getting the impression, it was changing down. At the apex, you would floor it and that was followed by a kick-down. All very smooth and manageable. Pretty impressive, so yes Mav, I would have to agree with the reviews.
What was clear was that the old school of driving (brake-gear-corner) is irrelevant with the DSG/ESP technology.

so you were driving in D or S mode (most probably D by your description).... and the gear box automatically shift down when you start to accelerate away from the corner.

irrelevant.. yes, fast... no

S mode. And no I do not advocate doing what I did yesterday on public roads.

Just out of interest. A work colleague of mine has an 08 TDi golf with dsg. Does this have launch control like the R32 and gti?

No, the diesels don't support launch control.

Cheers thanks for that.

Freaking wish they did. More torque than an R32/GTI yet still NO launch control :duh:

Yes, I think that's why the diesels don't have it. More torque. Can you imagine releasing 350Nm of torque in one go?

Would be a nice feature but not sure if it's more than my modded 32, 380Nm..

I get wheelspin now without Launch :D

We're equal ;) But I still think you need to take me for a spin...

Lauch doesnt seem to just "Dump" in one go, it takes up drive over a few hundred miilliseconds. This can make a BIG diff to mechanical loads.

I find it interesting that my manual makes no mention of the launch control function?:confused: Perhaps they didn't want us to know about it!

Sounds like you got a torque monster there yourself! should be able to arrange it sometime.
How many kW you got? Need a bit of both ;).

I'm guessing you mean instruction manual? I've heard they have a section in there all about it.

Haha ok perhaps that's where you get me.. I've only got 125..

Ah yes but torque always equals horsepower at at 5252 rpm so youve got at least 125hp too :horsepoop:
