Could this be the begining of the DSG Issue on my Octy????

[dArK5HaD0w]

that' bad and I certainly wouldn't call it normal.
mine doesn't exhibit any of those "features".....touchwood.
i'm on approx. 65,000 kms sofar.

1) When im at a stop in D mode, 50% of the time the engine idles a touch rougher than the other 50%. If I change to N or P then it idles smooth.

My car also does this

It can be the air con placing a load on the engine causing a rough idle (vibration)
The variable nature of this is because the air con is not operating at the same load all the time
When it gets the cars interior down to the requested level the amount of work and load on the engine both reduce
(I can only presume moving into N reduces gearbox oil/clutch drag on the engine - so it's two things together causing the problem)

Next time this happens simply turn the air con off and see what happens

5) Just before I come to a full stop, there is a slight shudder

That's the car (transmission) changing down into 2nd and letting the clutch out
Same as per a manual it's just that you are not expecting it because you did not change down
It's more noticeable when changing down to lower gears

6) When driving I find that in D mode, unless im flat to floor, changes will happen no higher than 3,000rpm. Sometimes im in 2nd/3rd and i'll push more on the accelerator to speed up faster in hope that will hold the gear a bit longer (till around 4,000rpm) and it will change at 2,500rpm causing not the greatest experience. I find this to mainly happen when under more load (i.e. going up an incline/hill). Down hill it changes a bit better...

Use more throttle - it will rev out higher

Use more throttle - it will rev out higher

Air con does make the idle rougher, but all these symptoms are when the air con is already off...

Thats what im trying to say... if I take off with a heavy foot, it will generally rev out a bit more and perform sort of how i want it. However, lets say I take off slow with minimal throttle and im in 3rd gear and I decide, lets go a bit faster. So I put more throttle but its like the DSG has already made its mind up that its going to change gears according to my original throttle amount of minimal (meaning 2,500 and less RPM). It seems that it cant adapt to the throttle... Then it causes me to push the throttle even more and then it will sometimes go from 5th to 3rd to speed up which everyone knows, aint great...

So from just wanting the DSG to keep the same gear (3rd) and rev out in that gear, instead it will change at like 2-2,500rpm from 3rd to 4th to 5th then possibly back down to 3rd..

Keep in mind that when I drive the car in Manual mode, it performs excellent. It still has the shudder when lifting the brake off and slight clutch slip in 2nd, but obviously changes etc are sooo much better...

Also, I do have a Stage 2 bluefin tune so apparently this might cause a slight issue with the torque rating or something..

Im gonna bring this up with the dealer also to see what they say... (Skoda richmond)...

[dArK5HaD0w]

Can't believe u guys put up with those dsg issues.
Then again, it is vw ur dealing with - they're gonna say that's "normal operation"
......and that Buu-sheet!!!

[bobski]

Have you tried removing the bluefin tune?

[dportaz]

Have you tried removing the bluefin tune?

Im going to do this on the weekend and see if all the issues still happen... The shuddering still definitely happens, just dont know about the changing issues etc....

[dportaz]

So I thought I would give you guys an accurate description of my issues...

1) When im at a stop in D mode, 50% of the time the engine idles a touch rougher than the other 50%. If I change to N or P then it idles smooth.
2) When im at a stop and want to take off, I lift off the brake and if I let the car go forward by itself without pressing the accelerator, it will shudder till the clutch fully engages
3) When I want to take off I feel there is a slight slip of the clutch in 1st gear
4) If I almost come to a stop (i.e. brake down to 5kmh) and the car is still in 2nd gear, when i take off the clutch will slip and the revs will build to 2,000rpm and then grab when the speed matches the revs...
5) Just before I come to a full stop, there is a slight shudder
6) When driving I find that in D mode, unless im flat to floor, changes will happen no higher than 3,000rpm. Sometimes im in 2nd/3rd and i'll push more on the accelerator to speed up faster in hope that will hold the gear a bit longer (till around 4,000rpm) and it will change at 2,500rpm causing not the greatest experience. I find this to mainly happen when under more load (i.e. going up an incline/hill). Down hill it changes a bit better...

Your thoughts...??

Hey guys,

Here is an update after I went back to stock tune for a couple days then re-flashed my stage 2 bluefin tune....

1) Still happens but i find that when it idles rough, its not as rough as before
2) Still shudders
3) Still slipping in 1st slightly as before (I didnt find this to happen when the stock tune was loaded so may just be the clutch pack not coping with the extra power)
4) Still happens... As mentioned in 3), didnt happen anywhere near as bad with stock tune so must be due to the extra power
5) Still happens
6) Changes are happening at much better times now and overall the car feels much better to drive which im happy with... Just gotta get the clutch slip and shudder sorted...

that's a shame........

So I have contacted the Skoda dealer that the car was purchased at and they are going to look at the car and see if Skoda can do a good will job considering the car has only done 40,000kms and just out of warranty. I mentioned to them the car has always exhibited these problems from new (previous owner has this in writing) but when serviced nothing was ever checked or done. Also discovered that their system was showing incorrect history on the servicing. In the books it shows 10,000km service and 25,000 service, but they only show 1 service done at 15,000km so obviously something aint right with their records... This helps my case because they clearly havent recorded things correctly.

When I did purchase the car, it was still under warranty so before it expired I took it to skoda and told them to do a full check on the car to see if anything needed to be fixed/replaced under warranty and as you can imagine, they said that everything is fine (so im guessing that they did a quick scan and nothing came up)...

After speaking with a few specialist's, it could be the mechatronics unit which is causing the abnormal shift patterns and clutch packs causing the shuddering and slipping.

Now im hoping that Skoda comes good for me coz this is something I dont want to have to fork out and fix myself...

I find with the '14 Fabia vRS that if I want yo hold a gear and accel gently then i need to be smooth and deliberate with the pedal. Same as driving my old manual. If I want it to kick down, I can push sudden and hard - will jump 20+km though, or flick the paddle. It then switches back to auto mode after about 8 sec.
If you expect it to hold gear at low revs, you may load up the drivetrain in a way not good for it, or smooth or with mechanical sympathy. I was always taught that smooth, keep it a gear that keeps engine in torque range and you will be fast, smooth and use less fuel. I also sometime like to accel reasonably hard to cruising speed (60 or higher) and then rolling out of the pedal to conserve fuel. (Get to speed quickly and not use munch after that). Ding know if it makes a difference, but I'm getting about 5.7 average now.

So an update.

Taken the car in to Skoda twice now. First time was so they could see what the issue is then report back to skoda... Since then contacted me and told me to bring it in so they could reset and update all the software on the dsg to see if that could be a quick fix... Took it in today and obviously as this is 99% an issue with hardware (clutch pack) it was a long shot and it hasnt worked...

They told me to drive it around for a couple days while it learns etc, and then if the issue still exists to contact them again to arrange for the clutch packs to be changed... Im hoping that once the clutch packs are changed, all my major issues will be gone and then I can look into doing a DSG tune sometime in the near future...

Let's face it, the problem is either software or hardware (or both, I guess). If the new software doesn't fix things (didn't help me at all), the hardware solution should work. All my DSG issues were solved when the clutch plates were replaced under warranty, so I'd expect your situation to be similar.

Update:

Spoke with skoda richmond yesterday and they are going to replace the mechatronics unit. On top of this, they are also going to do a dsg service and all I have to pay for is some of the labour component which is $260... Score...

Still dont think the mechatronics unit will fix the main issue of the car shuddering, but hopefully it might address some issues around shift patterns and smoothness overall...
