Argh. I'm still getting the elusive "grounding device error". Any ideas short of just replacing it with a ClipperCreek? Love love love the Taycan but the software and the charger leave a lot to be desired.
I'm using a 14-50 outlet and have had the electrician back to check it and the wiring all seems fine. The car actually charges successfully but then after the charge is completed the "grounding device error" occurs. The problem only occurs when using a timer - if I do Direct Charging from the app or car with the PMCC it works fine and I do not receive the "grounding device error".
I've been able to reliably reproduce the problem with the following steps:
1. Set a charging timer in the app. I generally use 85% and have the end time set for 7am. It doesn't matter whether I have one or multiple timers active. I generally just have one.
2. I use the general profile. Doesn't matter whether I use optimized charging or time.
3. The car charges successfully to the target charge rate. Sometimes it ends 1% below.
4. The charger shows the charging session was successful
5. If I leave the car plugged in, within about 45 min the fault occurs. The charger release button in the car turns red and the fault shows on the charger. If I unplug the charger from the car as soon as the charging is completed, the fault does not occur.
Here are some applicable screenshots. I have a service appointment in 2 weeks...
