Engine Compartment Control Units

Engine compartment Control Units
As usual, there are a number of important control units in the engine compartment. The electronics box on the left at the front contains the DME control unit. Depending on the equipment option chosen, it may also house the EGS (electronic gearbox control) or the SMG (sequential/manual gearbox control) unit. The DSC (Dynamic Stability Control) unit is attached near to the left wheel arch.
A new feature as compared with the Z3 are the suspension strut mounting cross braces bolted between the wheel arches and the engine bulkhead.
