Is this 100% confirmed - that WMA7 involves a hardware update? I just got my MY20 and PMCC back from both WMA5 and WMA7 and the Taycan tech at my dealer said the PMCC update was only software for my unit. Maybe I already had a new communications board in there - but my care and PMCC were delivered about a year ago so I don't know when there was a cut-over if it was before then, nor do I know how to tell which version I might have. This isn't likely a problem at all for me since I have a private garage and no need for any of the features I suspect such a hardware update may enable - like VIN and SOC communication from the vehicle to the charger...The WMA7 update, updates the power and communication board from the mobile charger connect. You can not do this at home! Only Porsche is able to do the necessary update from the Power and communication board of the Mobile Charger Connect.
