    Issues Clearing MCU v1 Error

    A tool/device that has connections to allow me to send messages on the CAN bus (one of the TSLA Pro devices from AliExpress). Unfortunately, Tesla Toolbox v3 doesn't work with my Terga-based MCU so that set me back several bucks and about a month. Tesla Toolbox v2 isn't available to end users in...

    Issues Clearing MCU v1 Error

    Similar issue here with my out of warranty Model S! Of course Tesla wants to swap out the drive unit ($6k just for the unit plus labor and misc parts) rather than rebuilding it in the shop. If @stang_shane or @andyjmfrank or others might be up for helping me troubleshoot I'd appreciate it!
