Visit Preferences to set your user name Summary of change: '''This page is about VAG electronically controlled throttle''' '''Overview''' This is a DBC ('''Drive by Cable''') VAG throttle body used on a large range of VAG models. The newest VAG models have DBW (Drive By Wire) throttle bodies. '''How it works''' The DBC throttle body contains * two position sensors (variable resistors) * one end switch and * a DC electric motor to adjust the angle of the throttle. Spring return to closed position ** Is this 12..14V and what max current? (are the 1.1A stepper driver channels able to drive it or not ?) ** Does it withstand 14V continuous drive even in the end-position ? (for how long?) '''Inside''' See [http://www.home.no/mk1classic/VEMS/TB_Diagram.jpg DBC circuit diagram]. Pictures: http://www.home.no/mk1classic/VEMS/VAG_throttlebody.JPG Can Someone tell me if the connector is micro-power-timer or junior-power-timer (likely) size? (see ConnectorSelection or tycoelectronics.com if unsure about sizes, or just measure the pin dimensions, like "2.68 x 0.8mm"). I saw an apparently matching female 2x4 one-end-rounded connector housing on the front-cover of a tyco catalog (could not find the product inside though, except in 2x4 pin microtimer size - on http://www.tycoelectronics.com ).

Pictured throttle body is not fully motor driven. * Only throttle plate position at idle is controlled with gear motor. * Hence this is cable operated, but idle is controlled with gear motor. * Has two potentiometers, one for idle position feedback and other for measuring cable operated throttle plate opening angle. ---- '''Sources''' * VAG item number ? ** VDO unit.
