This used BMW ECU DME / CAS4 theft locking module with lock cylinder and key, OEM part number 8631689, also replaces several other 86-series modules including 8664660 and 8639594. Pulled from a donor vehicle, it pairs the engine computer with the CAS4 immobilizer system and a keyed lock cylinder—all in one unit. Designed for BMW’s 2.0L turbocharged four-cylinder, it controls engine management and vehicle theft protection. Programming to the vehicle/VIN is required upon installation by a qualified shop or dealer.
