New MCU AND 10.4?

ok, I couldn’t find an answer, so starting fresh.

I picked-up my S75D Saturday (and love it, obviously).

Question: it has software 10.2 and though I have the trunk open feature on my app, the AP doesn’t appear to have the update (the auto-lane changing is abrupt, to say the least). Has anyone with recent deliveries and the new MCU received the update?

The new MCU doesn't get 2018.10.4, that is for the old MCU. As far as we know 2018.10.2 is the most current version of the cars with the new MCU.

The Model 3 appears to have gotten the EAP update in 2018.10.5. We don't know what version will contain the updated EAP for the S&X.

Update: Someone just reported getting 2018.10.6 on a car with the new MCU: New MCU model issues, anyone?

So that is probably the version you should be looking for.
