I have exactly the same issue, when its in slow moving traffic, the switch between regen and drive seems to be very harsh and jerky, however, my other half has a 2021 Passat GTE and that doesn't have the same jerky issue that I have in my Octavia, even in slow moving traffic it is pretty much smooth as silk when transitioning between regen and drive.

There was a link posted in page 1 of this thread to another thread where it is suggested that these car's don't have an alternator. I have just checked the user manual for my car and that states the 12V battery is charged along with the HV battery. My HV battery gets charged regularly, so I can only assume that makes it either a fault with the battery or the charging system for the battery.

That's exactly what happened with me the first time I noticed it. Driving in e-mode to a destination, then with close to 50% HV battery remaining as soon as I pressed the button to start the car the ICE fired up. It wasn't anything to do with the car being in sport mode, or to do with the external temperature, or draw on the battery as nothing was switched on. Out of question, when it does that have you ever looked at whether the hybrid system is trying to reserve charge/charge the battery in the drive mode selection? And re the 12V battery - are they using really bad 12V batteries for them to not have sufficient charge in a 2 year old car?

I know this is resurrecting an old thread but I am having a similar issue, but it seems to be tied to the Battery Hold level, and I don't know if I'm just being a bit thick. I bought my iV a week ago, and my driving is broadly split into a commute which is 100 miles each direction where I would use hybrid, and on one direction set the HV battery to use around 50%, and use the remaining 50% on the return journey. The remainder of my driving is relatively short and well within the reach of the e-mode. A few days ago, the battery was showing around 45% charge, and as soon as I started the car, the ICE started and the car would not go into e-mode. I unchecked the Auto box in the e-mode manager, and the white line was above the current level of charge. I then manually moved the line until it was as low as it would go, and after a few minutes the ICE engine switched off and the the e-mode came back on. This morning I was driving on hybrid (in auto mode), and the ICE was running from dual carriageway use, and had been running for about 10 minutes or so, and even when I was stopped at traffic lights the ICE would not switch off, despite having over 70% battery charge of the HV battery. So again, I unchecked the Auto box in the e-manager, and the battery was set to battery hold at 75%, and I was getting the same "unable to use e-drive" message. There was nothing that was causing high energy drain as the climate control was set at 20 degrees with no A/C, and the car was fully warm. So I moved the battery hold level to the bottom, re-checked the auto box in the e-manager and still it was saying the e-mode was unavailable. After another few minutes at set of lights I turned the ignition off, and restarted the car, and miraculously the e-mode became available. Is this a potential software issue, that using the reserve charge level function in the e-manager, is somehow overriding everything else even when you are in e-mode or automatic. And once the software gets itself into a knot it doesn't know how to sort itself out?
