Just wanted to thank everyone who supplied answers here. I've got a '22 Enyaq iV 60 and I was having huge problems with Octopus intelligent Go and an Ohme epod 7kW charger - immediate charging fine, but smart charging failed every time. The car never seemed to wake up for the smart charging times in the middle of the night, although the first smart session which charged for a few minutes on plug-in would work OK. Software version on my car was 3.8, but it was updated before I bought it. I went through the process described here, pulling out fuse 3 for a few minutes - I think I went for 10 minutes - and then replacing. I'm sure I heard an extra 'clunk' at about 6 minutes. Anyway, end result was that it now charges perfectly on smart charging, waking up in the night to charge with no problem. So thank you! that's why forums are great.
