We had our phase 1 SE LR in at dealer for updates to help solve charging issues last week.
Had generally always behaved across mix of Granny, home ac and rapid dc charging for most of its 10 months since new.
Started getting various problems that became more frequent just after the very cold weather set in at the beginning of Jan e.g.
- car failing to start charging on schedule,
- failed charges overnight (some due to out of range current warnings after 20 mins or so where charger then locked out for safety) these actually lessened the more we reduced the charging amp draw allowed via the charger itself though at the time,
- charging port/lights slow to wake up, (would often fade in with a hesitant flickering) and then also charging port lights failing to illuminate at all (I did manage to reset them via the fuse pull method at the time to get them active again).
Service report shows that they updated various out of date modules to include BMS / BCH / CCU /EVOC / GW / IMCU
Anyway, so far so good as we've had it back on the ac charger a number of times since and all working as expected again....for now.
They didn't update anything else like the infotainment firmware's though so will be back for that come 1st service time in a few weeks.
