Hey yes we sorta got it fixed, but no smoking gun as to the cause/fixed. I’m in the clinic today. I’m a grad medical school student. I’ll do a longer answer tonight.

Thanks for the reply and yes, I appreciate that you have far more pressing concerns at the moment given your profession; I am sure we are all in awe and eternally grateful to all who are members of the health care system.

I managed to find him on FB, and he was very helpful , but unfortunately was not able to offer a simple fix. My car also now appears to be "fixed"

As he said to me "there is no smoking gun"

His car was in the shop for months with the garage chasing and checking wiring and connectors. In the end they just found that the faults disappeared, but they did not know the fix.

I had similar luck , but a little less vague. Ultimately, specialists boiled it down to being a wiring/connector issue , somewhere in the car and suggested that all I could do would be to check as much wiring as possible.

I checked a few areas and then went to the centre console and removed that. It was apparent from some residue that a liquid ha been spilled in the gear selector area and that had gone through to the wiring and connectors below. I also found that part of the loom was potentially rubbing against a sharp trim screw. I carefully cleaned all the connectors and pins and slightly rerouted and reinforced some of the wiring. I then had no issues, until about three days later. I couldn't do anything at the time and would have to wait until I could find time to check other areas. But I never needed to. The issues never came back , and haven't done so in about a year.

So take your pick on what fixed mine:
1. New alternator, which was badly needed anyway
2. New BMS, which was also reset a few times
3. Refurbished instruments, but they had other issues anyway
4. New battery, the new battery I previously fitted was not holding charge properly, but that could have been caused by the electrical issues as I was getting some strange charging behaviour
The problems still persisted and became more frequent until:
5. I played with the wiring in the centre console ( lots of large connectors carrying the HS and MS can bus there and most of my faults related to the MS canbus)
One more instance of the faults, then nothing since.

Personally I suspect a dirty connector. It would work intermittently when there was enough charge to jump the connection, but would fail when the charge dropped ( which the BMS dictates when the battery is fully charged, or under acceleration) ?

Hope that is some help

Did anyone ever come up with a solution? Countless threads addressing it with no solution 😞
