DSG judder

[JACUPRA280]

Thought I'd start a thread to see if anybody else's DSG behaves like mine.

Behaviour 1

When coming to a complete stop slowly (approaching a set of traffic lights, for example) or doing an emergency stop, the DSG holds onto second gear for as long as possible. This is normal behaviour - I get that. But what I don't think is normal behaviour is the 'judder' the transmission gives right before the gearbox goes into second. It's the same sensation you get with a manual gearbox, if you hold onto second for too long before dropping the clutch at low speeds.

Does everybody else's DSG judder when going from second to first? Sometimes I think mine is going to stall!

Behaviour 2

Second of all, I had an odd one today. On the motorway I floored the car from 60mph. The gearbox dropped down into third, however it hesitated for two seconds before selecting 4th. It's the first time the DSG has missed a beat. Anybody else experienced that?

I've noticed my dsg stutter a a couple of times today when coming to a full stop. Not sure what the box was doing as I was busy watching traffic. Ill be sure to check gear selected if it happens again. I wondered if it was down to the colder temps and the engine cold.

 

[MyLeon]

No judder at all on mine, and no hesitation. How many miles and how old is yours? It doesn't sound quite right...

On my third DSG (2 Biza's before the Leon) and none have ever missed a beat or juddered.

B1 - Mine has never held on to second gear when slowing slowly or quickly, however, I have felt it a couple of times jerk into first, but only very slightly and doubt if I had of had anyone else in the car they would have even noticed.

B2 - I presume you used the kick down button, so yes there would be a slight delay in getting from gear 6/7 to 3rd. Without using the kickdown button I would have expected 4/5 to have been selected, but slightly quicker than getting into 3rd..

I have had similar experiences when start/stop is activated. When coming to a stop, just before I have actually completely stopped the car the engine attempts to shut off and creates a stalling sensation.

Everytime I get in the car now I turn it off, surely it can't be good for your turbo either, constantly shutting off the engine.

I think I've only noticed this when I've pushed the stick to the left to put it semi-auto/manual mode.

If I manually shift down to second while coming to a stop in traffic, as I get to about ~5 mph: it changes to 1st in the upper corner of the center display but will judder about a second later. I'm assuming that's either the clutch going in, or it's actually changing to 1st and it is a bit slower than the display. I think sport mode does the same, but I don't tend to use it in slow moving traffic.

 

[MyLeon]

The box will change down automatically at low revs in manual mode anyway, if you also manually change down at about the same time the dox will shift twice, (which will take a long time) and give you the effect you are getting....?

Yeah, it's probably because it's changing from 2nd to 1st as a reaction, maybe if I change to 1st myself instead of leaving the software to decide it would be smoother.

It just seems weird changing into 1st while still moving, and coming to a stop like you would in a manual.

 

[MyLeon]

Try leaving it along altogether when slowing down, the box will down shift happily for you.
It maybe that you are trying to change from 3rd to 2nd just after the box decides to do the same, but it hasn't actually done it (the numbers change some time before the box reacts) so you double chance from 3rd to 1st hence the sudden jerk.
These boxes aren't all that quick between deciding to change and getting around to it. The actual time to physically change gear is quick, it just sends the 'go' signal by post instead of email!

The majority of the feedback here has been given I feel without understanding what the problem is, and that's my fault so let me clarify:

Behaviour 1

When the gearbox is in second and I'm coming to a stop, it'll hold second for too long which makes the clutch/gearbox judder before changing into first gear.

Behaviour 2

I floored the car from 60mph and the gearbox went into third as it should. However when it was finished in third it redlined for a few seconds before actually going into 4th - it missed a beat.

I want to know:

Does anybody else's gearbox judder when going from second to first?
Has anybody else's gearbox redlined and not selected a gear as quick as it should have?

 

[MyLeon]

Ok, I see what you mean.
B1. No, mine doesn't do that and nor should yours.
I'll have a play on my way home and see if I can make it do it.
B2. Mine has only done this when I've been in auto, and dropped a couple of gears with the paddles to get ready for a quick overtake (box now in temporary manual mode) and then forgotten to change up before the box reverts to auto.
I'm not sure if I have ever used the kick down whilst in manual to see if it drops a couple of gears on its own.
Again, I'll play on my way home...

I'm pretty sure I've had both of those behaviours when the gearbox is in semi-auto, but never when in D/S.

 

[FRTSIman]

The only time I have any problem at all with the operation of the DSG gearbox on my October 2013 1.8TSI 5-Door FR is when slowing down towards a stop in slowish traffic with the gear selector in S (Sport Mode), when the transition from 2nd to 1st and then to a stop is somewhat jerky and hesitant. This happens irrespective of whether or not Start/Stop is activated. This never happens with the gear selector in D (Drive Mode), when the car always come to a stop smoothly.

I don't seem to have any of the other problems either with a delay in pulling away from stationary as some others have experienced on this forum. In fact, I find that with the 1.8 petrol engine, the 7-speed DSG gearbox seems to be an almost perfect match!

Sorry for being a bit dim... Are you in manual when you do this?
If so then it's normal as you need to change gear before you hit the rev limiter! The box will hang there for a couple of moments before changing automatically if you don't.
If you are in D or S then it shouldn't do that.
I did try putting mine in manual and then hitting the kick down....6th to 3rd and I was off! (I'm running a TDI Tuning box so approximately 240bhp). Bloody good fun!

B1 - Mine has never done that.

B2 - Mine has never done that, regardless of if in D, S or manual on paddles..

 

[JACUPRA280]

Okay so it sounds like B1 and B2 are not normal.

The funny thing is, I have a feeling that the DSG in this thing will fail at some point. I reckon these behaviours are a sign of things to come. It feels like the clutch is weak when B1 happens.

 

[kiddo]

How many miles has the car done?

 

[tom81]

I have both behaviours happen in my cupra.
A while ago I had the gargae do a software update on the dsg box, but has happened again since then.
I think I have had behaviour 1 maybe twice and behaviour 2 maybe three times, its my first dsg box and have kind of assumed that it may just happen sometimes!
Might have to have another outing to to the garage but they just annoy me.

 

[zondaff]

I've experienced behaviour 2, infant I've seen videos of S3's and R's doing the same, it selects a too low a gear, then shoots to the next gear to protect the engine from hitting the rev limiter which is nie on impossible (unless the 4K revs was removed at idle).

Edit: I'd be worried about he first behaviour though, definitely a stealer visit
