Battery management issues VW New California T7

Out van has been back at the dealer for 2 weeks. I just had an update that a software update has been installed (not 27H7) that deals specifically with battery drain. They “say” that this seems to have fixed the problem.

Can you advise the software version showing?
 
I have an appointment next month to update. I'm having the same problem with the battery. I've temporarily solved everything with solar panels xd1755512733211.png
 
I picked up my Ocean just under a month ago and went on holiday for a couple of weeks pretty much straight after.

I have only really been using the Cali as a "car" since picking it up and the only thing I noticed with power was the main vehicle battery was draining quicker than I would expect.

This weekend I purchased a EHU and connected it up on Saturday evening for the first time. After connecting up the cable I could see the display showing both batteries appeared to be charging and there was stated current draw from the EHU.

I've just been out to check something on the Cali and now the leisure battery is showing empty and 5v and when I tried disconnecting and then reconnecting the EHU I get an error saying no campsite power and an orange symbol on the display.

One of the things I wanted to check on the Cali was the pass thru sockets so I used my socket tester and both sockets showed as having live and neutral reversed. I checked all my cables and even used an external camping extension lead to test and the sockets on that showed correct wiring.

So do we think that the battery issues might be affected by something being wired up wrong in the Cali?

BTW it's a Diesel vehicle.

Traded in our T6 for a hybrid Ocean 2 weeks ago, went on a weekend camping trip. Prior to purchase checked with the dealer re battery issues as we were aware of potential problems. Were advised all was good and no updates needed.
Charged high voltage battery on arrival at campsite, no EHU but on Friday night leisure bakery was fully charged. Left the van with fridge on on Saturday morning, leisure battery at 70%, the vehicle was untouched for 7 hours. Returned to find leisure battery at 20% and 12V engine battery out of charge. Switched off fridge, but to no avail, all electrics in van stopped working - lights/doors/water pump. Shortly after when opening driver door vehicle alerted me to stop driving (?) as hybrid system not working, Shortly after this the boot and side doors were deadlocked. I called VW assistance who advised they could attend at 3am - this was 7pm. I advised we would not be leaving overnight and to delay until the morning, I asked if it was safe to sleep in the vehicle, no VW technical assistance available so was given answer that they didn't know. Lovely campsite hosts gave us a bed for the night. Assistance arrived in the morning, took 2h to get the van to move with a power pack attached and mechanic had no idea why this finally worked. 6h wait for low loader, again needed power pack and some chanting to get it to move (at one point we thought we wouldn't get it on the low loader). Vehicle should be back at dealership this morning but currently demanding our old van back and a refund - this van is at best a multivan with a bed and a non functioning water tank, it is definitely not fit for purpose as a camper van.

How did you get on with this - have you been refunded?
 
Update, as others have witnessed my display panel says the leisure batteries are at 5V but a multimeter confirms both are just over 13V.

Ive just called the dealer I purchased the van from, which is 100 miles away so not somewhere I can just pop into, and they said that according to the VW recall my Cali isn't affected/covered by the recall.

I was hoping to pass on my findings so far in the hope of it helping them help others but they pretty much said, either bring it into them or just go speak to my local Van centre.
