Alternator Voltage Regulator 12V Valeo 2 Pin L DFM B Circuit IR IF BMW 318D 320D 330D X3 X5 Freelander TD4 REG0059
Alternator Voltage Regulator 12V Valeo 2 Pin L DFM B Circuit IR IF BMW 318D 320D 330D X3 X5 Freelander TD4 REG0059
Vehicle Compatibility
Alternator voltage regulator for select Valeo alternator applications on BMW and Land Rover vehicles where the alternator uses a matching 2 pin L DFM connection (plug type IDF-L) and the same control strategy. Specified as a B-circuit regulator with IR/IF (internal regulator / internal fan) configuration, active lamp function, and short circuit protection. Listed for BMW diesel applications and Land Rover Freelander TD4 where the alternator reference matches ALT0047A. Confirm by alternator label and plug style before ordering.
