DSG: Problems, Questions, Likes and Dislikes

[BrisGTI]

Has anyone had the following with their GTI DSG

The following is happening more and more.

The story beings....
Over the last 2-3 months I have found that when I change gears under load (4k-5.5k rpms) I would get the fart noise some times. The other times it is like a full auto were the revs drop slowly and there is no fart noise.
I found that this mostly happens when the engine has warmed up or have gone for a highway drive or if I do a left hand turn and I am in 2nd gear and then when coming out of the corner and giving it some it does the full auto sound no fart noise change even though I am in manual and I change gears via the paddle\gear shift.

I first thought it is time to service the forge DV I have installed, I received a service kit from Forge and went ahead and change springs and cap and re-greased and put it back together.
Found that it was still showing the same symptoms. (DV Services was done 5 weeks ago)

E.g. Last night driving home along the high way I was able to get fart noise when I was over taking people and changing gears. But then suddenly with no warning when I went over take again there was no fart noise but just the auto sounds when changing, even though I was up in the 4k rpms and in 4th gear.

The following mods
Apr Stage 1+
Apr exhaust
Forge DV.
Carbonio CAI

Any thoughts on this issue would be great or if people have had the similar issue and they found a solution would be good as well.

I'm still yet to figure out how to consistantly get the 'fart' noises during gear changes. Manual mode seems to be the more consistant but D & S is more random.

It comes down to engine load and revs. If you are driving sedatively, you will not get DSG farts. If you're driving spiritedly, you will get DSG farts. If you're driving flat-out and shifting just before or within the redline, you will not get DSG farts.

The DSG 'fart' occurs as a result of the ECU momentarily cutting the ignition (spark), to prevent engine torque from being transferred through the partially open clutches during a gearchange (which is in fact a clutch/gearbox change). I guess the cut always happens on a shift, but you probably only notice it under heavy throttle at specific revs due to the nature of the exhaust and the frequencies required for it to resonate.

As Corey says, engine speed and load make a difference, as would the selected gear, and your mods (particularly exhaust mods, but also anything that affects engine torque to some extent).

I find it's much more noticeable in my car at 2500-3000rpm under heavy load, 1st to 2nd and 2nd to 3rd, in manual mode (so I control the shift point, and the shift speed is rapid).

[TDI DSG]

I'm currently onto my second DSG box in a MK6 TDI wagon. I still have a MK5 TDI also.

Have had the new one for a few months now and would have to say I prefer the way the MK5 DSG shifts and "thinks".
The new one seems to almost flare on changes and feels more like a torque converter auto. It felt the same in Tig's I test drove also. Then there is the downshifting everytime you touch the brakes - good idea but it seems to go down one gear too many on most ocassions leaving you needing to then accelerate on a down hill to get it to change up again.

The MK5 just seems to be a firmer more positive shift. I can understand for some this would be a negative.
All in all still far better than a conventional auto or CVT !

yOU'RE LUCKY! mINE HAS BEEN BACK 3X FOR THE SHUDDER AND EACH TIME THEY SAY THE SIFTWARE UPDATE HAS (oops.. caps) fixed the problem.

I think the "we updated software" comment is a fob off half the time. I mentioned my DSG quirk which has happened 5-6 times since December and asked about an update. They said there is no "update" for the DSG in the R anyway.

Golf R DSG Is this normal?

I figure it probably is but there's a 'grabbing sensation' and hesitation when I take off,especially on a hill start.
Just asking if anyone experiences it without sounding like a dill.

[Lucas_R]

That would be the "normal" clutch engaging sensation that the DSG's have. Although i have a manual, i have driven plenty of DSG's over the past few years - and the smoothest way i have found to take off is to quickly/lightly tap the acellerator to engage the clutch and then back off, then apply your normal amount of throttle you would use to take off from the standstill.

Thanks Lucas.I'll try that.It feels like the handbrake is dragging bit it's fine.
Thanks for your help.
Everything else is just wonderful about it!

So you mean it feels like it hesitates on hill starts? It's hard to say without test driving a car to see whether something is wrong or is working normally. Many people who buy there first VW freak out and think something is wrong with there gearbox(DSG) when it's just the way they perform. Just when you release your foot off the brake the car should hold for 3sec until it engages gear, that is if you haven't already put your foot on the accelerator.

[LWR]

That's exactly what it's doing. I'm certainly not complaining,just curious.
Thanks for your help guys.

[Corey_R]

The DSG is not an automatic gearbox. People referring to it that way causes much of these "worries" in customers. It's an "automated manual gearbox" - and therefore has a clutch and stuff and can explain what you're feeling.

However, since you say you notice this especially on hills, what you're probably noticing more than anything is the "Hill Start Assist". When you take your foot off the brake whilst on a hill, the car leaves the brake applied for ~3 seconds to give you time to accelerate without rolling backwards. It'll release the brake once it knows there's enough acceleration to not roll back, but it can certainly leave a "grabby sensation" on some hills.

[LWR]

Thanks Corey_R.I think you nailed it for me.It's just what I would have imagined an HSA to be like.
I'm not worried at all but curious about my 'clutchless manual'.
Thanks again for going easy on me!

I got that just now driving now. I'm also noticing that the DSG is staying in 4th a lot longer than it should. I find myself hitting the up paddle to kick it into 5th.

I just drive mine manually most of the time now.A mate has an R35 GTR and he does the same too.It's really quite unimpressive in Drive around town.
