2010 Skoda Octavia DSG7 - judder in 3rd at ~2500 rpm, uphill shift hesitation, delayed engagement from standstill
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.

2010 Skoda Octavia DSG7 - judder in 3rd at ~2500 rpm, uphill shift hesitation, delayed engagement from standstill
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.

2010 Skoda Octavia DSG7 - judder in 3rd at ~2500 rpm, uphill shift hesitation, delayed engagement from standstill
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.
