I seem to have the same issue since a few weeks. Let me try to explain:
Home charging station is wall box 1 phase 230 Volt, 16A.
Since a few weeks it doesn't charge my VW e-Golf 2017. When I plug it, you hear the clicking sounds of the wall box and the car. Indicator goes green intermittent (as if it is charging), but it doesn't give any power (I have a separate meter for the station that shows no consumption) After a minute or so new clicking as if it is trying to charge again. This happens 3 times and then the indicator goes to yellow and red.
My car charges fine with a public 11 or 22 kW charger. Also fine with the 230V Level 1 (10A?) charger (The one you plug into a 'normal' wall socket)
My neighbor can charge his car fine with my home charging station so it looks like the charging station is fine.
What could be the issue here? Could there be a separate charging fault for 1 phase 230 Volt 16A inside the car?
I've read that resistors are used to define the type of charger connected. Could there be a fault there?
I've gone back to the dealer, but they don't seem to have the knowledge to analyze the issue or have never dealt with it.
Any expert that can help here please?
