There is a software update/fix for Superb iVs suffering from a variety of charging issues. The charging issues are:
P33DF00: Rated current request too low
P33E100: Charge socket A electrical error
P31D500: Charging socket A recognition connector lock electrical error
P33E800: Charge socket A, charge connector lock mechanical malfunction
P33E000: Target/actual current deviation too large
Mine had P33E000 from new. I took it back in within a couple of weeks of getting it because of the poor battery performance. They told me there was nothing wrong, so I downloaded the DTCs myself and found this one occurring over a hundred times per charging cycle. They submitted it to Skoda for a fix. They never told me that a fix had been issued - which is annoying. I found out by coincidence when chatting with a service manager at a different branch. He looked it up while we were talking and found it. It is not a standard update that will be applied to your car, it is only done as a fix for identified issues. If they don't download the DTCs, they won't find the issues or fixes. There is no indication of these issues in the dash/infotainment system.
After the conversation with the service manager, he emailed me the list of faults the update addresses to double check it was applicable for my car and I downloaded the DTCs again and found that several of the listed fault codes had appeared multiple times since I last downloaded the DTCs. My car is going in for the update next week. I don't know what the fix does. For all I know, it could just suppress the error codes. The service manager did seem to think it would improve battery performance though, so I'm guessing that there is some info about the update that suggests it might.
On what I though was a totally separate issue I had to contact Skoda customer services because my car lost all connectivity (the dealer told me outright they could not fix it), including the spanner button on the overhead panel. The error message it gave me was that the license had expired. It seems that Skoda then forced an update to restore connectivity. Since then it has been downloading software updates like crazy. Either Skoda have just released lots of updates in a short period, or these are overdue. Suddenly, my electric range jumped up to 30 and with a bit more driving has crept up to 36. There has been no change in driving style or distances. I was getting mid 20s previously. I considered myself lucky if it got up to 28. I bought the car a year ago so I have had it through all seasons and never had it perform as well as it is now. Battery performance did plummet on the coldest days though. There are lots of good tips out there to combat this such as setting the charging cycle to finish just before you want to drive so that the battery is pre warmed. The only other change of note is that my Skoda Connect subscriptions have expired. I would be surprised if those services were power hungry enough to affect the range of the car. They hardly ever worked anyway though, so I won't be renewing them.
