BMW Color Codes are usually found on the Color ID Tag in the driver-side door jamb or B-pillar area. The Color ID Tag is typically a sticker or plate; on some models and years it may be under the hood, sometimes at the back of the engine compartment near the firewall. BMW Color Codes are usually 3 digits, but can also appear as A52 or an older format like 354/7; common examples include 300, 475, A52, or 354/7.
