What is the purpose and process of the throttle body on BMW Z3?

The throttle body of most BMW versions consist of the throttle plates that regulates the amount of air going towards the engine and typically connected to the accelerator pedal by cable, except for 5 Series models with traction control that use Electronic Motor Load regulation (EML) system. EML simply employs an electric servo motor to drive the throttle while a sensor on the accelerator pedal sends information about position of such a throttle to the EML controller from which it is relayed further down to a particular servo motor that will enable opening or shutting down of an approximate 90 degrees valve plate. In other words, EML does not need separate cruise control actuators, transmission control cables and throttle cables as all these functions are accomplished using only one multi-pin electrical connector into which the ECU connects with its counterpart on the TB. Nevertheless, it's important to note that any repairs related to the EML system require special BMW tool and should not be undertaken without access to this tool. The steps taken when removing and installing a throttle body depend on type of engine being worked on including draining coolant systems, disconnection of cables at different points such as hoses (which also serve as vacuum lines), removal of throttle bodies which involves cleaning mating surfaces, torquing mounting nuts among others. However, extra caution have to be taken when dealing with S14 engines in order adjust certain components and make sure gasket integrity is maintained appropriately. Basically speaking these procedures ensure correct operation of TBs as well as related parts in BMW vehicles.
