Necessary Specials Tools
The BMW secondary voltage test adapter kit (12 7 040)
BMW special tool 12 7 043 (adapter cable)
Special tool 12 7 041 (single adapter) for fitting to the ignition coil.
NOTE: When checking the compact ignition coils (e.g. M43 Eng.) use additional special tool 12 7 045.
Special tool 12 7 042 for connecting special tool 12 7 041 to the BMW Service Tester. This adapter replaces the high tension pickup which is normally used when checking non Direct Ignition System (DIS) ignition systems.
