They couldn't get it programmed, so BMW in Germany remotely connected to their dealership and they couldn't get it programmed to the car, either. So, they tried a 2nd module. Still failed. So they told him they needed to replace all the battery wiring. That didn't fix the problem, either. So they tested each battery module and decided maybe the HV battery was the issue. Those modules were replaced under warranty. The cost to him for the other parts and labor was $5,000 USD. The car was at the dealer for 20 weeks. He sold it a couple weeks after he got it back because he doesn't trust that another component on the car will set him back even more money and time.

and on this one as well, same question: how many miles on this i8? and what is the year of the car? Does anyone have a clue as to whether it is miles on the car, or just age that causes this issue?
we should start a sticky thread for this issue, so people can chime in as it escalates--or does not escalate--and figure out if its a lemon problem, or a certainty that all i8s will face, down the road.
for example:
With the HPFP (high pressure fuel pump) issue on the E66 760Li, we at first thought it was miles, only, since the the cars were newer. People with 10 year old cars that started to crest 100-130k miles or more, suddenly popped up with the issue--and they all eventually developed it. Then, as they got older, I bought a 2004 with 59k miles in 2018. It had the issue the moment I got it home. So, it was also age that caused a cheap diaphragm in the $2500 pump (there are two pumps + labor) to go bad and split or get a hole in it and leak gas into your throttle body. The pump is special and only made for the 760Li (V12 motor only) and the Rolls Royce.
why is this important? because it would brick the cars and make people want to sell them. Just like this issue is starting to do.
I'm not saying we can DIY this problem, but on my first HPFP failure, I sent a used pump to a DI fuel pump expert in Canada, who tore it down and figured out it was in perfect shape--except for a diaphragm that Bosch would NOT sell us. So I set about figuring out how to replace the diaphragm with used parts from Audi and VW Bosch Diesel TDI pumps from Europe, since there was nothing like it in the U.S. Now, we have board members making inexpensive replacement diaphragms out of material they can get from Continental. And dozens of copy-cat videos (of my original video) of how to repair the pumps.
by the time I bought the low-miles 760li, I had confidence I could contact my forum pal, buy some diaphragms, and get the car back on the road for $100.
It might be possible to encourage a 3rd party company to help figure this out. Like Gruber.
any pathology information we can gather is very important, please.
