			=== Oil ===
			The MG Drive Unit calls for Shell SP2808 E-Fluid, which is generally hard to obtain. Suitable replacements are (but not limited to):

			* ROWE HIGHTEC TOPGEAR SYNTH E SAE 75W
			* Fuchs TITAN SINTOFLUID FE SAE 75W (this one is GL-4, unknown if that's suitable for the MG Drive unit)
			* Fuchs TITAN SINTOPOID 4218 SAE 70W-80

			The capacity is 0.9 liters.

=== Parking Lock Actuator ===

The original parking lock actuator (Electronic Parking Brake) EPB uses a three phase brushless motor with three hall sensors as feedback and is controlled by the Electronic Parking Motor Control Unit (EPMCU), which is controlled via CAN. There is an additional sensor on the side with two hall sensors that gives feedback to the car's VCU.
As of now, the EPMCU is not reverse engineered.
[[File:MG MG5 Drive Unit Parking Lock Actuator.jpg|thumb|alt=|When the arrows point towards each other, the parking lock is engaged. The pictures shows it disengaged.]]

==== Connectors ====

The connector for the original actuator is currently unknown.

The connector for the feedback sensor fits the VAG part number 4F0973704, which can be easily found as repair pigtails or crimp sets.
