Great! Is it a secret, or could you offer further details?

It's not possible to code start-stop Off, and SFD2 cannot be unlocked to set Lane Assist to "last setting". The only thing that worked for me on SFD2 was to switch off the overspeed warning chime.

Yes, problem is still there after PV4RC updates on the car (including SW 2768 on MiB); phone is also an S25 Ultra. It works flawlessly for several days/weeks, but sometimes it just fails several times a day...

If most of your trips are motorway, I would suggest you go for the TDI; if I'm not mistaking the vRS TDI is also AWD... However, since you mentioned it's on a 19 plate - wouldn't that make it an Octavia 3 facelift? AFAIK Octavia 4 started with '20. The mileage on the 1.4 TSI iV is quite high for a PHEV, you should pay special attention to the service history - those are prone to quite a few gearbox-related issues. The DQ400e is not the smartest/most reliable thing VAG has built. indeed, if you tend to drive it like you stole it (alternating a lot between "pedal-to-the-metal" and "hard-braking") - yes, the gearbox will be jerky, noisy and sometimes seem to hesitate more than you would like... I found the flappy paddles on the VAG phev are only useful in two scenarios: you drive in EV and you want to force/increase regenerative braking, OR when you're in hybrid sport mode and want/need to have control over the gear change while driving spirited; when you really want to know what gear it’s in, simply put the DSG in S instead of D; to see the engine revs you have a few dashboard view options - at least one with a rev-meter; true, you get a lot of wheel spin with this PHEV configuration (on all VAG models that use it), since they poorly manage the electric motor torque when starting from a standstill, even on dry surfaces. The key is NOT to floor it when the wheel is completely stationary; first let the car move a bit and then you can "launch" it - you'll find this changes the car response dramatically. Also, having a grippy tire helps a lot! Mine was delivered with LRR tires and those were loosing grip quite often; I replaced them as soon as I could.

Indeed, it'a a SW package called PV4RC that includes (potential) updates for all control units as you mentioned - only for the facelift versions of various cars in VAG group: Golf, Octavia, Leon, Formentor etc. The newer the car, the less updates to be performed; e.g. mine was manufactured mid-2025 and still they found a few updates to install.

The "disabling" message you received is referring to some functionalities that were removed from the App - independent of what your privacy settings were. Those who used older versions of VAG Apps (VW, Skoda, Seat/Cupra) will know that sometime last year during one of the updates we were notified that the honk and flash functions were removed. For ICE vehicles the App might not seem to be a big deal and probably not worth to pay for. However, for those with PHEV it is really a big deal: not only you can remotely start/stop the HV battery charging, but it's really convenient to precondition the cabin before departure (cooling in hot summer days, heating in cold weather).

I can only help you with this problem: switch the gearbox from D to S and the car will go into hybrid mode even when your infotainment has gone crazy.

The air conditioning should not impact this process, since it uses an electric compressor, not a "mechanical" one, and electric heating before the engine water heats up. Did you check the temperatures (water/oil/gearbox) during your trip? If you drive 30/day I'm assuming it's 15 km each way, and it's possible that temperatures are still not optimal at the end of your trip, given the cold weather outside... (just an assumption)

Well, on a fast road section (90-100 km/h and above) you know the ICE will run to maintain speed (unless the road is downhill). Furthermore, if you put the gearbox in S you will have complete manual control of the gear, therefore control over the rpms. However, getting the GPF warning on a PHEV is quite rare, I'm assuming it must be triggered by a very clear pattern: a large number of very short trips in hybrid mode (not EV), without any long trip to break that sequence.

Well, that's not actually 100% true, because going downhill with the present technologies the car will either do a lot of coasting, or if it will not coast but it will use engine-braking - there will be no gasoline in the "mixture". The user manual quoted above does indicate/suggest a normal procedure to clean the GPF.

First thing first: DPF - diesel particulate filter GPF - gasoline particulate filter most recent gasoline engines also have a particulate filter, in order to comply with Euro 6(d) standard. You probably need to drive for a longer distance using your internal combustion engine and NOT using the lowest revs possible.

Post a picture of the headlights and we'll let you know... E.G..: pre-facelift (with Matrix): post-facelift (with matrix):

...User Manual? Let's not forget that leaving the key inside the car while washing the car, is a (widely used) way to avoid the car locking and unlocking + folding/unfolding mirrors.

The heating (PTC element) or the cooling (electric compressor) are both powered from the HV battery. The "brains" of the process, control and coms with the servers (if you send the command from the App), power relays and (I assume) the cabin ventilator (that blows the heat or cold inside) are fed from the 12V - the flimsy as you call it. If you have the car connected to a charger (HV) before you leave, ideally you should charge the last 10-20% of the HV battery before you leave - this also acts as some sort of pre-conditioning of the battery, since it raises a bit the temperature while charging (you mentioned very cold weather). In this scenario, starting the cabin heating several minutes before you leave should have no impact on the 12V battery, since the VAG logic is to also charge the 12V battery (if needed) while charging the HV one. p.s. looking at the screenshot you sent, I realized I miss the exterior temperature showing in the Skoda App. The idiotic Cupra App doesn't have that displayed, and I bet the information is available on the server (sent by the vehicle when requested)

Let's not forget better looking both on the inside and outside! 😁 However, Octavia has a lot more space to offer...

The facelift Octavia has SFD2 implemented, which means that you will not be able to code anything related to the Lane Assist - since the corresponding module is locked. However, I was was able to set Speed Warning to Off (or Last Setting) using the OBD11 one-click-app. Just follow the procedure indicated in the description of the App (open bonnet, ignition on...). Concerning the EPB auto-engage, AFAIK if you have the Auto-Hold activated when you stop the car, the EPB will be automatically applied. (this is actually one of the reasons I do not use the auto-hold 😁)

Well, in fact there's a catch here... the Seat/Cupra never released a 1985 version for MiB3 as Skoda did. Instead, they released version 1988 with several months delay compared to the 1985 version of Skoda. This is making some users think that the "delayed" 1988 version of Seat/Cupra, is actually a combo of fixes/improvements included in 1985 and 1989 by Skoda. Whether we like it or not, all brands of VAG will run a (very) similar software on their cars (using the same hardware) - it's just the release dates and the UI that are different. That's why bugs and errors are the same over the entire group for cars sharing the same systems.

Do you have something newer than version 15.2.653614 (Sept. 16th on my phone)?

You can try at: [email protected] and / or [email protected] (I can't see where you're from)

You should be thankful that it threw out an Error, and you didn't brick your system. The software on the facelift models (Octavia, Golf, Leon/Formentor) has nothing to do with the pre-facelift, since the hardware is different. Check you software information - you should have a version close to 2650. Do NOT try to install an inferior number version! If you have annoying bugs on your system, try to discuss with the dealership. I've heard rumors about a major update for MiB4, but it's not yet released OTA.

I also think the problem is most likely to be AA. Those encountering the above mentioned issue - did you try to Clear Cache and Data in AA on your phone? (I'm not saying it will definitely help, but it's worth a try)

The PHEV models have the 12V battery in the trunk. Look under the boot floor, on the left hand side you'll see a plastic cover held in place by several screws. The 12V battery is under there.

I have the same "problem" on my Formentor facelift (same HW and basically the same software behind the UI). On average it "offers" the new settings about once a week; and yes, if you ignore it, it will keep popping up at each new start of the car. In my case it only changes the color of the ambient lights and the setting of the headlights sensitivity to "Medium" (I prefer to keep it on "Late"). It seems it imports the set of settings from the server; what I can't understand is why the car doesn't update the modified settings on the server. Once I change whatever I want to change, I go to User, select mine and tap "sync settings" - that should upload the new set to the server... I had a trip to the dealership (for a different issue) and also told them about this problem. They said they never heard anything similar (sure - we've all heard this argument before), they have no idea how to tackle it and they also concluded: "But it doesn't seem to be such an important problem - just ignore it and keep driving!" 🙄

Have a look at the attached Workshop Manual pages (I had to cut the original file, since it has ~70MB size and the limit here is 10MB). Seeing the procedure in the Manual, it seems to me there's no need to disconnect the HV system, but I'm no specialist. I'm guessing that when the 12V is disconnected, all the HV and high-power relays are off - so there's no actual risk. AFAIK, there's no need to code anything after - since the battery is the same. When it is replaced - that's a different story. The Manual is warning that errors are normal after 12V disconnect/reconnect, but most users mentioned those errors are gone after a couple of complete steering-wheel turns left-right and after several driven kilometers (or miles if you prefer 😁 ). 34_Electrical_system - Car Service Repair Manuals and Wiring Diagram_reduced.pdf

While playing with the 2 keys in & out - did you also check on the infotainment to see what User does the car "Welcome" when you open it? Is it the correct identification key-user? It might sound quite obvious, but while doing the above test with the 2 keys - did you make sure that there's only one key in the "detection area" of the car?
