    Ugh. I have been driving my Roadster pretty rarely due to COVID and I discovered the dreaded Battery Service Required error message.
    Going into the VMS, the debug code is apparently Battery Bleed Scan.

    The car charges fine as far as I can tell.
    Below are pictures of the VMS. Anything I should be doing? Is my battery dying? (Please no!)

    Car was only serviced "recently" by ExecMotorwerkz (a couple of months ago but I probably have put less than 100 miles on since).

    It looks fine at the moment. The battery may eventually get out of balance, and if that happens you will need to get it fixed. Sounds like you have the common loose rivet connection on one of the bricks. The bleed test checks the ability to bleed off voltage to balance the pack. It could be OK for years, or start giving you problems next week. Just another one of the many design flaws in the Roadster Tesla refuses to correct at no cost. They will be more than happy to take lots of your money to fix it however.

    Thank you for the responses. I will contact Peter.
    I did charge the car after the error popped up and it charged to full (in standard) and the error went away.

    I spoke too soon. The error is back.

    Looks like my sheets are all pretty well aligned ...

    Yes, everything looks fine right now. You will notice a drop in range if the pack gets out of balance, so I would just ignore the warning until then.

    Thank you ML!
    Greatly appreciate your insights as always.
    Now I wish I still had the other battery ;-)
