  • Why is there white, crusty buildup on my M340i’s battery post? The white, flaky stuff that can build up around your M340i’s battery terminals is known as corrosion.

If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • How do I clean a corroded M340i battery terminal? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your M340i owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
