The update just fixes an issue with the Service schedule indicating you need service sooner than you should. It doesn't provide any actual powertrain changes.

Where did you get that info JLR? I checked with the service tech and he mentioned something about driveability issues.

I was told the same thing when they did mine 2 weeks ago.

The "recall" regarding a real powertrain issue is only for 2019 vehicles and is under a different campaign than what the OP was asking about. I got this information directly from my Service Advisor.

Yes, the more dangerous/real of the two (engine could stall) only affecting 2019 models.

Mine was updated while in the shop for rattles. Mine had three recalls/campaigns, but I don’t have the paperwork in front of me to detail what they were.
