GM6 BCU

The GM6 BCU is, like the earlier GM3 BCU taken directly from the BMW stable and converted to suit a different model. In this case all Rover 75. A very sophisticated and integrated unit, it controls a large variety of different sub systems throughout the vehicle such as Alarms & Locking, Doors & windows, Wipers and washers.

There are two different versions of the GM6 ECU, a high line and a Low Line and visually they are identical except for the colour, the low line (pictured ) is near white and the high line is near black. Functionally they are identical with the exception that the high line one has the capability to operate electric windows in the rear of the vehicle.
