HFM ECU Ignition Circuit Board for Mercedes-Benz 6-Cylinder VDO 019545193203

Product Details

Replacement ignition circuit-board module for compatible Mercedes-Benz VDO HFM engine control units. It is intended for component-level repair of a verified failed ignition-stage circuit while retaining the original ECU. This is an internal electronic repair part, not a complete engine control module.

Fitment and Compatibility

Applicable to select VDO HFM ECUs used in 1980s and 1990s Mercedes-Benz W124, S124, W210, C202/S202, and related models, including certain 220E/E220, 260E, 280E/E280, 300E/CE/TE, 320E/E320, and C230 applications. The source catalog contains engine-count inconsistencies, so vehicle model alone must not be used for fitment. Match an ECU number below and compare the board and pin layout before ordering.
