Ready to race!
You understand the rationale behind not starting the engine during the update perfectly. Start the engine before the update, disable start-stop, then run the update. If you have a good quality battery maintainer you could hook that up instead of running the engine.I see it says do not start engine during update. Presumably that means it’s ok to start the update while the engine is already running? (And disabling start/stop?)
An additional tip: Turn off the lights (which usually come on automatically), set the parking brake because in some markets that turns off the DRLs, and turn off the heating system. Check that heated seats & heated steering wheel (if fitted) are off.
