Battery management issues VW New California T7

[kaifetzer]

Well we were beginning to think we were one of the Lucky Few.
NAH
Went out to the van this morning both batteries flats as pancakes.
Going by Vin no: our vehicle 'shouldn't' be affected

I think that if you drive the van regularly, you don’t really notice the issue because the batteries keep recharging.

But once you pay closer attention — or if you actually go camping without shore power — you will inevitably notice the problem.

I believe that many people are not even aware of this issue yet.

Our camper first had a software update, but then was the subject of another recall. They are apparently replacing 3 components, and it seems to focus on the “gateway” that manages the batteries.

Maybe ask your service partner about this gateway, there was another poster somewhere in this thread they seem to suggest his issue was solved by this too

Hi, thanks for your tip. I couldn’t find any detailed information about the gateway.

Could you please provide a bit more information, so I can explain the technical background to my service partner and know what exactly needs to be done?

That’s all I know I’m afraid. A google suggests as follows:

An automotive gateway is a central electronic module that acts as a router and security firewall for all data communication within a vehicle, connecting different electronic control unit (ECU) networks that use varying communication protocols like CAN, LIN, and Ethernet. It translates data between these diverse systems, filters and processes information in real-time, and securely manages communication between the vehicle's internal networks and external networks for features like over-the-air (OTA) updates and diagnostics

We had the same issue, but since it discharged leisure and 12V batteries in its maiden trip it has not restarted even with a replacement 12v engine battery. We were lucky (?) only had the van for 12 days so rejected the vehicle and have our old T6 back and a full refund.

I spoke with the service department again, and they told me that my vehicle was apparently not affected by the Scaleways recall. It seems that only a few specific models were impacted.
