After battery change I get random warnings that disappear.
Do modern cars require battery coding/registration? Any modules to reset first?

Some cars need battery registration so the charging strategy matches. Also check voltage stability during install; undervoltage can trip multiple modules.

If you can, scan for undervoltage history. It often reveals which module complained first.
