DSG Question

[Azzamataz]

Hi All

After having the 77tsi for one week with DSG, and changing from a 12 month old manual 77tsi, i have a couple of queries about the DSG.

1) The car seems to roll back when you take your foot off the brake and transfer it to the go pedal. It does it on any small or large hill, once you actually press the go pedal, its not a smooth transition and jerks the car forward a bit. Should the car roll back? Seems very odd when in drive.
2) at low speeds (less than 10km very light throttle) the car seems to shudder a bit like its about to stall.
3) when you plant the foot to overtake, it seems to take longer than expected in an auto to drop a couple of gears.

Are these normal attributes of a DSG. So far I'm not in love with the car, and the manual was a much better drive.

Thanks to all the DSG owners in advance for any assistance.

I had all those issues with my previous TSI but it wasn't that big of a deal, you kinda get used to it after a while. But yeah the DSG is well known to show all those symptoms especially at low speeds.

Mated to the GTI, however, it's seems to suit a whole lot better, much smoother and less jerky even at the low speeds.

If you can get over the minor DSG issues...the 77TSI is a great little car.

1) Never noticed, the car comes with hill assist so holds the brakes for 5 sec to prevent rollback, it does jerk a bit when accellerating from standstill, not sure if this comes from the hill assist not releasing the brakes before I apply throttle
2) My car sudders a tiny bit when releasing brakes and just letting it creep forward, but not even close to stalling?
3) the gearbox is slow on the kickdown indeed takes forever to figure out what gear you need, select it, and engage. S-mode is wayy to agressive. Just takes some getting used to and learning to put your foot down just a little earlier to compensate

My main drawback with the box is the rattle when driving over uneven roads

To activate the automatic Hill Hold, after coming to a stop you need to partially release the brake (or press it further if you only had light pressure) and then press it again. You will feel the brake pedal become rock solid. Now you only need to hold very light pressure on the pedal for the brake pedal to hold.

Now when you "take off", there will be no roll back.

I have never had the shudder issue.

On the response to kick down, this is pretty normal. The system does have to figure out what it is that you are doing. It is not the same as a torque converter type auto where everything is charged up and working on hydraulic pressure. There are a number of controllers and inputs that need to be considered here.

The difference is in fuel consumption. Rather than pay in consumption to keep everything charged up, there is a delay. It has never really been an issue for me. Try and adapt to it and not expect it to change.

The DSG does take some getting used to. I'm finally starting to 'get' mine. At low speeds, you can tell when the clutch is engaging and the car kinda 'bunny hops', but ever so slightly.

In terms on the way that car changes gears etc, the ECU is a learning one, so it will figure out your driving style and match the gears to that. That just means you need to be quick off the mark each time

1) yes its normal for the car to roll back... you will get used to it and learn that the car WILL actually stop you from rolling more than you think you are... its a weird sensation but if you dont hit the accelerator then the car will engage the gear and stop you from rolling.
bunny hops are not normal - but they may occur occasionally - if it occurs ALL the time then take it for repair. it should be a smooth take off from a standstill regardless of whether you are on a flat or a hill.
2) once you are moving you will be in 2nd gear... then if you travel slowly it will use the clutches to engage/disengage to keep the speed you want. this is probably what you are feeling.
3) known "behaviour" of the DSG. I hate it... but have learnt to adapt my driving to suit its little "habits". if i know i have to overtake rather quickly i shift it over to the "manual" mode and manually shift the gears before overtaking. it seems to take an eternity to shift down unless your foot hits the floor.

Personally i prefer a manual... but give the car some time to grow on you... the DSG is not perfect - and there is definitely some engine/DSG combinations that are far better suited than others... you will learn as you go and the DSG will also adapt to suit your driving also.

Dont believe it is. For what I know the box simply operates according to values. It knows what revs you will have in any gear, when switching to any gear. Because it is electronically controlled, not hydraulic.
It acts to simple rules, gear down @ 1100 rpm or load above x%, gear up at set rpm (input by throttle) or rev limiter (pre programmed)

The DSG can be completely reprogrammed to your needs, values can be changed. You can even get full control in manual mode if you want, without kickdown/rev limiter etc while in manual

After dropping off the gti yesterday to have some rattles looked at, I got given a 1.4 trendline with dsg as a courtesy car. My god, that thing was gutless! But, the interesting thing is that it too was afflicted with the same symptoms, more roll-back in D than my gti, slight shudder at yesterday's conjestion speeds and the kick-down aprehensiveness. Got back in the GTI and none of those issues were present. Perhaps it's just down to the better mated combination of the 1.4TSI/7SPD DSG....

[Hail22]

Can't fault my baby, she is smooth, lean, perky and very grippy i cannot stop loving this DSG/TSI combination

[danntsi77]

i find the S mode in my 1.2 tsi awesome, dropping down gears at a moments notice.....it has never shuddered or rolled back on hills.
I normally drive on the freeway/country roads in S mode with cruise control on so if i need to overtake quickly it more responsive...

1.2tsi DSG. No roll back ever. Period. DSG sometime slower to change down a gear at lower rpm, but on the money at middle to upper revs. No judder ever. Period.

Judder, rolling backwards, strange noises .... Take it back. If it doesn't do what it says on the packet, you might have a Friday 4.55pm lemon.

[Hail22]

Roll back was never an issue, also for a weird reason if you depress the brake really hard and release guess what? your car shouldn't roll forward thats what my car does xD

I've had my GTi for about a week now, and I have a query about some experiences I've had with the DSG box. I have mainly been running the box in manual mode only. I also try to avoid activating the hill assist by slowly pulling to a stop and not putting to much pressure on the brake pedal the car seems to operate in a more conventional "auto" mode which is what I am more familiar with. There have been two instances that when I have gone to pull away there has been no drive on a slight incline where the car just continues to roll back. I blip the throttle trying to get the drive engaged but no luck. First time I shifted back to D (drive) and the car again had forward drive. The second time, this did not work, and when blipping the throttle the engine was just dying and no drive even in D. I shifted to R to try and get the transmission to respond and eventually it did, shifting back into D and finally getting moving.
My query is, does this appear to be an "operator error" and I need to get used to the box and should I use the hill assist and get the DSG to do its thing. Or does this appear to be a fault. I've only experienced this in manual mode not D or S mode.

Any ideas?

^ Don't do this.

You need to press brake pedal firm, then DSG knows what to do, whether there is need for hill assist on incline or just 1st gear for normal takeoff.

[RoknRob]

I agree with Markwid. I had a similar experience to you, piston broke. Almost rolled into the car behind me. Has never happened since I've followed the advice above.
