Throttle assembly, removing
and installing
Some throttle assembly faults will reset
the engine control module (ECM)
adaptation values. BMW's diagnostic
tool (DIS or MoDiC) or aftermarket
equivalent tool is necessary to reset
ECM adaptations after throttle
assembly replacement.
CAUTION!
After replacement of the throttle
valve assembly, and/or on MS 43.0
systems the pedal position sensor,
an adaption procedure must be
performed using the factory scan
tool or equivalent. The vehicle will
not start unless this adaption
procedure is carried out.
Disconnect battery negative (-) cable in
luggage compartment.
CAUTION!
Prior to disconnecting the battery,
read the battery disconnection
cautions given at the front of this
manual on page viii.
