Online Update - HV battery control unit (WTD4)

[Paul Fireblade]

My J1.1 Taycan wanted to do an over the air update today WTD4 for HV battery Control unit, looking on line I can only find details regarding earlier updates.

Any info regarding this one, anyone???

Apologies, typical I now find a relevant thread on this forum already, Tried to delete but couldn't find an option (moderators feel free to delete.) Relevant thread:

I don't know what the update is for, but I noticed my dealer listed that as one of the recall updates to be done when I take it in for the heater to be replaced:

Factory Recall Campaign WTD4 Re-programming high-voltage battery BMCe control unit 1

Mine hasn't offered to install it OTA (yet).
