My 2024 Octavia has now been back to the dealer multiple times for this exact issue, most recently for a three-week period of diagnosis and road testing with Skoda technical involved after we rejected the vehicle. Skoda have emailed the dealer to say the issue is caused by the engine ECU shutting down the engine in order to protect the dual mass flywheel when it detects a potential stall condition at low RPM. So it's working as designed and there is no fault. Their official guidance is to modify your driving style to avoid low RPM in higher gears. I have searched through the user manual and on Skoda's website but can find no mention of this. Learner drivers have been taught the "brakes to slow, gears to go" mantra and to use block gear changes for decades (as per DVSA guidance), so for VW Group to tell us otherwise is astonishing. I have kept a detailed log of incidents and I will now be submitting a report to DVSA.
