My car was updated last week. The garage confirmed that the software update to the gateway module was specifically to address the problem I had been having, where the 12 volt battery is completely discharged. The 12 volt batterywas checked and is apparently ok.

So i anyone is experiencing a total discharge of the 12 volt battery, there is a known issue and a software update available.

Request a written statement that the hotel battery was fully tested and is undamaged. I'm really interested if they will do that. 

@rmills Have you tested the terminal voltage of the hotel battery while the HV battery is being charged since the update?

Absolutely no chance. Customer service here is not exactly outstanding but the dealer knows that if my battery fails in the near future they will have to replace it. That is a fight for another day

Been having 12v issues with my Octavia IV vrs since I got it last year. It was in the garage for 3 months last year attempting to fix it, seemed ok for a couple of months then all of a sudden complete discharges of the battery overnight again. Just picked it up from the fuse flashback fire risk issue recall and they found the December 2022 firmware update to fix the 12v issue, hoping it's fixed now, next couple of days will tell as would almost always be dead if I didn't plug in the hv charging cable over night. Also did loads of firmware updates on Infotainment system as that kept rebooting. Hoping but not holding my breath that this is the end of 2 years of issues with 2 separate Octavia vrs's...

Weirdly after going through the same process in January and having been assured that ny 12 volt battery was fine, I got a low battery warning this morning. Now I have to try and get Skoda to replace the battery, as I think it must have a shortened life from the previous lack of charging and constant discharging

Experienced my forth 12v battery failure, in ten months of ownership, this past weekend. Needless to say I have contacted VWFS to start the rejection process. 

 

 

Hi,

 

I know this was two years ago, but did you ever get to a resolution with Skoda?

 

After the fourth 12v battery fault last December, the Octavia was sold and replaced with a Toyota Corolla self-charging hybrid. The best car I've ever owned: 2 litre engine but with the eCVT we get up to 60mpg on a run and 80+mpg on short trips. Faultless, everything works as it should and a ten-year 100000 mile warranty.

Hired the sedan version about 3 years back holidaying in the Australian Northern Territory and while that had the less powerful 1.8l engine I concur it was amazingly economical. That was with the aircon on permanently to cope with the high temperatures and humidity.

The hatchback is a bit too small and the boot miniscule. Unfortunately the estate version is not available here unless as a grey import from Japan.

 

I have a 73 plate Octavia estate VRS iv PHEV and I have had the flat 12v battery problem twice now since I got the car in November 23.

 

The first time it happened the car was completely lifeless until I jump started it and it sprung back into life. I took it to the local Skoda dealer and they did an investigation but unfortunately couldn't find any problem with it. I then didnt have the problem again for around 7 months until sunday just gone when I cleaned the car, did a couple of short runs on the HV battery and didnt fully charge it since the friday since it seemed needless when there is enough % remaining. I cleaned the car inside and out then went to lock it when I had finished, the 12V battery was completely dead again and the car lifeless.

 

My brother came over the following monday so I could jump and, low and behold it sprung back into life, all of the assist systems displaying errors and then slowly resetting. Strangely the 12v battery didnt seem low at all or have any warnings, its as if it is blocked somehow and then jumping it springs it back into life. Very strange and worrying problem that this car has since its a work car and Im regularly doing long journeys, im even having to park it now strategically so the jump terminals are easily accessible. 

 

I'm going to inform the local Skoda dealer again but they seem clueless, nobody really seems to have much experience with these cars. Im also going to invest in a noco boost jump pack to keep in the car as back up, if it happens again i'm going disconnect the 12v battery terminal and see if this can bring it back to life when its restored.

 

I randomly have had the low 12v battery warning on start up on and off although not recently, the last time was at least a month before the recent dead 12v problem and once restored i'm not getting the warning which is puzzling. I didnt spend any time charging it before using it again once it was jumped which seems strange, I don't understand how it can just suddenly have enough power again?

Having this exact same issue, also 2023 VRS iv. Did you ever get a solution?

Thanks

I've owned my Octy iv Estate PHEV since October 23. Not only have I experienced the same (or similar) 12v battery problem, but also an absolute shed load of other problems. I've loved Škoda cars since I bought the first vRS in 2001, but this latest version has really knocked my faith in the marque. Initial problem, charging cable wouldn't lock into the charging port, so charging unit wouldn't operate. Called Richmond Škoda who gave me an appointment for 3 weeks later and told me just to drive on ICE in the meantime....... of course, 2 days later, car wouldn't start, 400v and 12v batteries both flat, so called Škoda Assist who attended within the hour. Technician was great, sorted the problem temporarily by jump starting the car which reset the charging unit and allowed me to charge the car again. He was incredulous that Richmond Škoda obviously had no idea that this was a fault that needed to be dealt with immediately and didn't realise that the 12v battery would die quickly. Since then, multiple intermittent faults with the particulate filter blocking, the front assist de-rating (particularly when it's cold or wet) and the latest, a regular fault message that the "climate control system has shut down. Fault with on board charger unit." Dealer insisted that they couldn't find any errors, so I invested in a Vcds diagnostic system which picked up numerous error codes, most but not all of which are "generic can-bus errors". Presented the printout to the dealer who looked again and told me that "all modern cars tend to have lots of errors which aren't important." So, no solution to any of the issues so far, other than don't buy another PHEV or electric Škoda until the dealers are properly trained.

Yes, had a new 12v battery and that seems to have solved it.

It got to a point where it was happening weekly, I even had to think about how I was parking to make sure the bonnet was accessible for jumping so I took it to my local Skoda dealer and told them to hold onto it till its sorted. They had it for about a month and observed the 12v was ok one minute then the voltage suddenly would drop causing all the error codes, not possible to start and ending with the battery going dead. They finally decided to try a new 12v battery. Strangely the old one still passed Skodas performance test so the garage didnt want to do it under warranty, it became an argument between them and the lease company. In the end Skoda fleet services said they would cover it, it was £ 300 so was even tempted to pay it myself while they were messing around!

I had to wait for 2 years to get the car after order so the garage suspected it was most likely parked up waiting for parts and the 12v battery was mismanaged meaning it was defective when I got it, could possibly be the same reason with a lot of them from this time. Skoda had terrible production issues due to covid, wiring harnesses from ukraine and I heard a fire at the Czech production plant!

Anyway 6 months on and I have more confidence in the car again, I have had the low 12v battery warning a couple of times but I think that's fairly normal and it quickly disappears when running.

My issues were solved with a new 12v battery. All the error codes were coming up because of the faulty one including lighting error, charger not locking in, epb error, assist systems not working, climate control etc.

I have it on a lease and actually started the process of exiting the contract, the garage finally tried changing the battery and it’s been pretty reliable for 6 months. They will try and avoid fixing it because they don’t want to do anything that will cost them money. Bizarrely the faulty battery actually passed Skodas test criteria as functioning correctly!!! I did manage to get it done on warranty in the end tho.

I’ve had an error code once or twice since but clears on restart so I do think there are certain things we have to live with, the flat battery isn’t possible tho.

I’m same as you on it really, love the car and Vrs series but wouldn’t go for another after all these issues or recommend to others.

In my opinion 6 months is way to soon to have 12v issues. I wouldn’t trust my car to drive 2000kms this summer if this happens to me. My new 12v battery is 1 month old and I do hope it will last at least 5 years.

I agree, I don’t quite trust it yet. I’m not sure if the low power thing is a battery issue or not, it’s displayed it probably twice since. I’d rather just have a car with an alternator tbh not this bull**** hv trickle charge, don’t think that helps.

2 years! Waited 18 months for mine and thought that was bad but sounds like a similar case. Also got issues with the overhead modules. Sometimes the lights are like a disco and it keep phoning the breakdown line! Really need to book it in

I'm jump starting mine with a battery powered jump starter at least once a week now. It's booked in at the dealer for 8th April. Battery goes flat when I have a door or boot open for any length of time or sit in the car with the ignition off.

It NEVER gives a 12V battery low warning before it happens though. It does give the warning sometimes when I start driving but never when I need to know. Can the warning only show when the ignition is on? If so that's a pretty serious flaw.

Get a new 12v in there, should hopefully solve it. When mine was doing it it never gave a warning, would just die after the cleaning the car or something. When it was going it was like I couldn’t save it and it would always end up going dead then needing jumping.

Mines been good for 6 months now and it’s a company car so done about 12k miles with no issues including weeks away without plugging in.

I hope it had something to do with the 12v battery’s that came with the car. I had to buy a new OEM one. So I hope this one just “runs” beter. Also I’m on the oldest software version. Can’t update myself. In June my car goes to the dealer for an update/check and they said I still need a recall done.

The first owner didn’t do anything about it.

Absolutely sick of this car now and certainly wouldn't buy a Skoda after this. Dealer says because there's no error code getting thrown up Skoda doesn't want to know. ****ing ****e.

@mccririck Is that what the dealer principle says personally to you.

I would ask them to put that in writing.

Which Dealership or Group is that?

I am pretty sure that Mathew Bowden of Skoda UK & Damien O'Sullivan of VW UK will be more than delighted to hear about the After Sales Service from That Dealership.

Well actually, surely they already know exactly how bad things are with the Products they are responsible for the sales of.
