Watching with interest.
This sounds very similar to the absolute nightmare I had with the dealers when my iDrive controller was replaced. I don’t know the full car history, so perhaps previous owner had other things done, but I had SLI enabled and when they went to code the iDrive controller they ended up with issues resetting the head unit. Car ended up off road for 5 weeks before having all modules recoded through an IRAP session with BMW Germany.
To be honest, much as I want my SLI back, I’m too worried of the same rubbish happening again, so very curious what the ‘way out’ is when this happens, as evidently dealers don’t have a solution.
