Cold day. Dead battery

[Reedy]

I had mine changed under warranty no problem. They just need the car for 2 hours just to confirm it’s the battery.

Less tech in the car to drain battery

Was more along the lines it has lasted that long despite only having very short runs that may not top it up fully

Same situation with our 2012 rs octavia. Short trips and still on the original battery !! Low tech cars ftw

If you have VW Assist, you’ll most likely get it replaced for free.

Yep. That’s what I’m hoping.

Edit: can confirm. I just spoke with VW Assist and they said the battery is covered under the whole car warranty.

Resolution.

Diagnosis and replacement under warranty as part of VW assist today.

^^^ I bet that VW assist didn't bother to tell the network module in your car that it now has a new battery and to stop charging/discharging it as if it was a battery of the age of the previous battery. I bet that they simply physically swapped new-for-old and just drove away- without plugging a device into the OBD port near the accelerator pedal?
I would be delighted to be advised otherwise

It was done at the dealer so I hope they coded in the new one. I have a VCDS cable. Is there an easy way to check?

[DV52]

^^^^yes - it's relatively easy to check: go to the CAN Gateway module @ address hex19, select adaptation-16, search for "MAS06108" and select IDE03256-MAS06108-Battery adaptation-Battery Serial Number. The factory setting for the original battery would have been 1111111111 (i.e. hexFF) - if the setting is still hexFF, then likely the CAN network is oblivious to the fact that the car now has a new battery!

PS - here's how to do it properly (mk7s have UDS modules - so use the section of the video with this protocol):

Checked. They did update it. Nice when people do their job
