I'm well out of warranty and my screen has already failed (several months ago and just pre the arrival of the global pox). Being stuck on an island without any realistic likelihood of getting the car off for another 2-3 weeks, I am seriously considering a DIY fix whilst I await MCUv2. I plan to keep the car for a few years, yet, and it makes no sense to me whatsoever to pay UK£1400 now for a replacement MCUv1 when in (hopefully a year or so) I can get v2 for a bit more.
I see the whole eMMC thing becoming a recall is hotting up. Perhaps it'll all become moot before long and I can have my cake and it it too (ie get a temp MCUv1 fitted for free and then upgrade to MCUv2 in due course) but not holding my breath) At least with a DIY fix I'll get my audio etc and full charge back (stuck with what it was when the MCU failed - 110 miles and a max 2A (yes, two amps) charge rate!).
Anyway, thanks for your input, guys.
