Hello,
I am on process to buy a CPO 2021 BMW x3 xDrive30e from a BMW dealership, I already gave 1K $ as a deposit with the condition to get it checked by an independent mechanic. When the mechanic did the diagnostic scan he got a bunch of code errors, but the one I am more worry about is:

030E77:
Intelligent battery sensor 2 (starter unit): Communication fault (LIN), read the standby current histograms.

Any idea what they need to do to fix this error?

Thanks!
