  • Why is there white, crusty buildup on my 340i’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your 340i car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I remove corrosion from my 340i car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals.
