Hi all,

I am looking for advice on an ongoing gearbox issue with my 2010 Skoda Octavia Sportline 1.6 TDI with 7-speed DSG.

The car has several symptoms, and I suspect they may be related:

1) Judder / vibration in 3rd gear under load
In 3rd gear, at around 2500 rpm, if I apply light-to-moderate throttle under load, the car starts to judder / vibrate.
This is more noticeable on an incline.
At the same time, the RPM needle fluctuates slightly.

2) Gearbox hesitation on steeper uphill roads
On steeper climbs, the gearbox sometimes seems to hesitate or not respond properly.
There are moments when it does not change gear as expected, and even using the paddle shifter to upshift does not always produce an immediate response.
This seems to happen more often uphill.

3) Very occasional need to press the brake again before drive engages
Very rarely, after starting the engine, the car does not engage drive immediately.
At that moment, the brake light comes on, and I have to press the brake pedal again before the car will finally move off.
This does not happen often, but it has happened enough times to make me think it may be related.

Important background:

• The clutches were replaced

• The dual mass flywheel was replaced

At the moment I am trying to understand whether this could be related to:

• mechatronic unit

• DSG adaptation / basic settings

• brake pedal / brake switch input

• sensor input issue

• hydraulic pressure problem

• clutch control / calibration

• or something else in the transmission system

There are no fault codes at this stage.

Has anyone seen this combination of symptoms before on this DSG gearbox?

Any advice would be greatly appreciated.

Thank You.

My Mk3 with 7 speed dsg does this if I shift into D or R to quickly after starting. As in less than 1 second after start. I suspect it is just me beating the computer's start up sequence.

I dont think its a big problem.

Solution: start, wait say 2 sec, maybe put seatbelt on, then engage gear and drive off.

Id say that's a common thing with DSGs, they can't always anticipate your conditions so yeah, occasionally it gets it wrong. No biggie

It is only common with DQ200,s not operating properly and what is common is that 1.6TDI,s with a DQ200 more often go wrong than with those fitted to a TSI.

Hi, thanks. I will try do see what happen, but I also think it's not a big thing, and it happens really rarely, but I can check if it's I am to fast :)

Hi, Thanks. It seems so, and it make sense not to change gear so it will not lose engine rotations.

Hi, Thanks. I also think that the electronic part is not like 100% tuned and working as expected.

Hi all,

Quick update on this issue after further repairs and testing.

Since my original post, the following additional parts/work have now been completed:

• Engine mounts replaced

• Gearbox mounts replaced

• Silentblocks / bushings replaced

Unfortunately, the vibration/judder symptom remains almost exactly the same as before.

Current situation:

• Still mainly happens under load / stronger acceleration

• Still most noticeable in 3rd and 5th gear

• Still much more noticeable uphill

• Still reduces or disappears almost immediately when lifting off the throttle

• No major vibration at idle

• No major vibration at constant cruising speed

So at this stage:

• clutch pack replaced

• dual mass flywheel replaced

• engine mounts replaced

• gearbox mounts replaced

• silentblocks replaced

...and the core symptom remains.

This is making me increasingly doubt that the original issue was actually caused by the clutch/flywheel/mounts themselves.

The gearbox specialist is now suggesting the mechatronic unit may be responsible, but I am struggling to understand how a mechatronic issue would create a vibration pattern that appears mainly:

• under torque/load

• in specific gears (especially 3rd and 5th)

• and disappears immediately when lifting throttle.

I am now starting to wonder whether this could instead be related to:

• inner CV joints

• driveshafts / half shafts

• differential/output side

• DSG output bearings

• drivetrain resonance/load issue

• or another known DQ200 issue.

Has anyone here experienced something VERY similar where:

• expensive DSG/mount/clutch repairs changed almost nothing,

• but the final cause ended up being somewhere else in the drivetrain/transmission system?

Any further ideas or experiences would be greatly appreciated.

Thank you again for all the help so far.

I'm interested to read this as my 08 Octavia (190k miles) has just shown similar problems. On a recent long run, reluctant to change up, slight juddering, though I think it's because the gears are going up and down as the rev counter is variable. I don't have any other symptoms though

I'm trying to get advice but am told it's probably the mechatronic unit and not worth repairing. I've searched various forums, not changing up gears seems to be quite common, more so on longer trips when the car is fully warmed up, and seems to signal the end for older high mileage autos.

I've owned my car for over 16 years, luckily I've spent absolutely nothing on it other than routine servicing so scrapping isn't a big financial hit. Nonetheless, I'm reluctant to let my rust free and otherwise reliable car go to the breakers.

Hi,

Interesting. My case seems slightly different because the vibration is actually much easier to reproduce when the engine is cold. Once fully warmed up it becomes significantly harder to provoke. Also, my vibration existed before clutch/flywheel replacement and remained almost unchanged afterwards. That is one of the reasons I am now looking beyond the usual DSG suspects and investigating possible combustion/injector related causes as well.
