Don’t know if this will help anyone else but…
I have had problems with smart charging ever since the 3.2.1 update. Essentially my ZAppi charger couldn’t initiate a charge, the car would go to sleep and not wake up.
I had multiple emails with CUPRA and they brought the car in for another update a few weeks ago. This seemed to make no difference to anything.
In desperation I posted on the Myenergi forum although it was obvious it wasn’t the charger’s fault. This link was suggested to a German ID3 forum. Seems ridiculous but it worked immediately!!
Posting here in case it helps anyone else (but not taking responsibility if it causes problems!).
