DSG: Problems, Questions, Likes and Dislikes

[Corey_R]

I'm told the Mecatronics is now an upgraded unit.

Yeah - there have been several revisions of the mechatronics for the DSG 6sp wet-clutch gearbox, but current MK6 cars will already have the most recent revision. So the topic of conversation for the last page at least is simply just a case of the car needs time to adapt and also run-in.

I have a shudder problem too on my 103TDI Jetta, but its not when slowing down, it happens in between lifting my foot off the brake from a complete stop and going to accelerate. If I lift my foot off the brake VERY slowly, I don't get a shudder, but if I just lift the foot straight off, there is a shudder everytime.

I just took it in for my 2000km oil topup, and got one of the guys to test drive it with me, and it happened every time. So now I have booked it in for a service proper to see what the problem is.

Amazes me how many types of shuddering there is with the DSG, Declanny, your shudder issue sounds similar to mine except under opposite circumstances. Mine happens when I have my foot slightly on the brake pedal, either when (most often) i am towards the end of the braking zone - slightly and slowly lifting my foot or (just recently) slightly pressing (10mm) on the brake pedal at very (very) low speeds.
Changed my braking style to adapt/overcome, by not lifting my foot till it comes to a complete standstill, you'll see my passenger's head nudging forward everytime.
Having it checked out once again at the end of this week.

Yes, if you put your foot down, the S mode will redline every time...

Realized two nights ago that when you floor the accelerator pedal to the max, well I thought it was the max before this...until...you give it a little bit more and you'll feel this 'click' then it allows you another >10mm past the threshold. Not sure if its just my pedal or if this is in every GTI...?

[rs73]

sounds like you've found the hidden "loose your license" button underneath the accelerator pedal! LOL

Gotta keep it under wraps then, thought VW tricked mine up as a freebie

Lol.... I'm not sure if you literally mean it's already on the floor, and then the click is it literally forcing its way past the "bump stop" (or whatever is there), or whether you are talking about the regular "light resistence" point where it then presses a switch called "the kickdown switch" (as discussed in the owners manual from memory).

The 1st option would be pointless. It's electronic so once you're at 100%, there is nothing more. The 2nd option means that the car will kick down a gear or two once the switch is pressed rather than hold the gear its in (even in "manual mode").

Just a quick update from my servicing for those interested.
1. DSG shuddering under braking while downshifting from 2nd to 1st gear and lifting foot off brake pedal within the last 1-3m of stopping, apparently this is 'expected' of these types of gearbox and is 'normal'. Dealership 'computer' checked the gearbox and found no faults, so I guess it's the driver being overly sensitive
2. Bonnet not releasing. Is in fact, as some you have suggested, (for some reason) the cable detached itself/came undone. Fixed.
3. Also got them to realign my steering wheel, it was a bit off to the right by about 2-3 degrees.

2 mins into my drive home from the service centre, noticed another commonly discussed issue, the ticking sound coming from the door pillar (near the seat belt). Overly sensitive again? Just turned the music volume up to help ignore the ticking.

DSG and Engine braking when on steep hills

MK6 TSI 118KW - I have noticed that the new DSG software appears to insist on engaging lower gears (engine braking) as you go down steep hills, which I find quite annoying, I am unsure whether this a setting one can change, anyone know?

My MK5 GT never seemed to do this or least I never noticed

[AdamD]

My GTI (6sp wet clutch DSG) does the same. If you leave it in D and apply the brakes on a decline, the engine will downshift one or more times until you're travelling at a relatively constant speed and can roll down the hill without riding the brakes. A slight touch of the accelerator and it'll cancel that mode and drop you into higher gears.

Personally, I think it's a great feature. But if you want to avoid it, just flick the car to manual and drive with the shifter down steeper hills.

Why do you find this annoying?
This is how you are supposed to drive when you are in a manual car.
1) It doesn't use any more fuel. In fact, it's using 0 fuel as the motion of the car is pushing it along (you can confirm this via your trip meter's instantaneous fuel usage).
2) It means you don't have to use your brakes as much
3) In the old days, it'd mean that when coming down mountain roads, you wouldn't crash and die from brake failure after your brakes over heated because you didn't change down gears and utilise engine braking

So yeah, why would a feature that makes an "auto" act more like a properly driven manual car, saving you fuel and brakes and thus money, be annoying?

[logger]

Like you say Corey_R, you cannot have the zero fuel flow without a gear engaged or the engine will stall. Dunno about the 6 but with the DSG7 if you were to drive along at say 100kph in 7th and take foot off accelerator pedal & lightly brake, it will work its way down thru all the gears keeping revs just above idle, while to the driver you are just mindlessly coasting to a stop. All the while fuel flow will be zero. Eventually when speed drops to a point where there is insufficient energy to windmill the engine just above idle, it will re introduce fuel and presumably ign. Very clever I reckon.

It can be quite noisy. It would be good if you could stop it from happening easily by tapping the accelerator or similar when you don't want the benefits of engine braking.

Thats all you have to do.... press the go peddle and the engine braking will go away.
Myself - I love it! Especially in sport mode when the engine does the "blip" before changing down a gear. Wonderful sounds from the supercharger and turbocharger. We twincharger owners can experience some beautiful sounds that the "turbo only" crowd cant hear. Boy do I love it. Stick your twincharger DSG into sport mode for a day and revel in the beautiful sounds. Wind the window down!!!
Doesn't get any better than this.
