Throttle cable, adjusting
(MS 42.0)
The throttle assembly on MS 42.0 cars uses a throttle cable.
The cable should be adjusted any time it is disconnected or
replaced. This procedure requires the factory scan tool or an
equivalent to read and adjust throttle angle. It is recommend-
ed the procedure be done by an authorized
BMW dealer ser-
vice department
Basic adjustment:
Ensure that at idle (accelerator pedal in rest position) throt-
tle cable has detectable play at throttle lever attaching
point. Play must not exceed maximum allowable.
Adjust by turning knurled adjuster
(arrow) on end of throt-
tle cable sheath at throttle housing.
NOTE-
Faulty throttle adjustment values must be reset using the
BMW service tester
DISplus, MoDiC, GTI or equivalent.

ldle speed control valve,
checking and replacing
3 mm (0.125 in)
The Idle speed control valve regulates Idle speed by red~rect-
ing air around the throttle valve. The ldle speed control valve
is mounted
d~rectly above the throttle housing. Accessing the
valve is best accomplished by
flrst removing the air fllter
housing and associated ducting.
Thevalve is supplied with batteryvoltage from the ECM relay.
The idle speed control valve incorporates a two-coil rotary ac-
tuator. The ground sides of each coil are pulsed simulta-
neously by the ECM. The duty cycle of each circuit is varied to
achieve the required idle speed.
A faulty idle speed control valve sets a fault code and the MIL
is illuminated when
OED II fault criteria are exceeded.
Before checking the idle speed control valve, confirm that the
throttle position sensor is working correctly.
- With engine running, check that idle speed control valve is
buzzing.
- Turn on AIC system or shift transmission into drive. ldle
should remain steady or increase slightly.
- If idle speed valve is not buzzing, or if idle decreases when
AIC is turned on, stop engine and disconnect harness con-
nector from idle speed valve.

Fuel Injection I
Working inside E-box, disconnect ECM harness connector
(arrow) by releasing fastener and pivoting connector up and
off ECM.
CA UTIOW
Be sure ignition is OFF before disconnecting or reconnecting
DME system components.
Remove ECM from retaining brackets and lift off holder.
Installation is reverse of removal
Before attempting to start engine, use
BMW service tester
DISplus, MoDiC, GTl or equivalent:
* Code replacement ECM with application information (i.e
engine code, transmission type, etc.).
Align ECM to EWS (electronic immobilizer).
Siemens MS 42.0 and MS 43.0
ECM pin assignments
ECM pin assignments are given in Table c. For engine man-
agement system schematics, see
ELE Electrical Wiring Di-
agrams.
/ CAUTIOW I
Al~ays wait at least one mfnule after turning off the ignition
before
remov;ng [he connecror irom rhe ECM. If the con-
nector is removed before this time, residual power
in the
system relay may damage the
ECM.
Always connect or disconnect the control module con-
nector and meter probes with the ignition off.
When making checks at the ECM itself, a
breakout box
should be used to allow tests to be made with the connector
attached to the ECM. This also prevents damage to the small
terminals in the connector. As an alternative, the harness
connector housing can be separated so that electrical checks
can be made from the back of the connector.

The lubricant used varies, depending on transmission and
model year. Fluid application information is clearly marked on
a label on transmission.
On manual transmission, either ATF (orange label reads
ATF-Oil) or a special BMW lubricant (yellow label reads MTF-
LT
I) is used. See 230 Manual Transmission.
Automatic transmission is filled with either Dexron
Ill ATF
(black transmission ID plate reads ATF-Oil), or special life-
time oil (green transmission ID plate reads Life-Time Oil). See
240 Automatic Transmission.
CAUTION--
If in doubt as to the type of fluid installed in a particular trans-
mission, consult an authorized
BMW dealer service depari-
ment for the latest in operating fluids.

of the manual transmission, as well as the removal and instal-
lation of seals at the transmission input, output, and selector
shafts. If these tools are unavailable, equivalent tools may be
substituted.

4 V-8 engine: Remove transmission mounting Tom-head bolts
(arrows). Note length and location of bolts.
Remove transmission by pulling backward until transmis-
sion input shaft clears clutch disc splines, then pull down-
wards. Lower transmission jack to remove transmission.
- Installation is reverse of removal, keeping in mind the
following:
When installing a new transmission, be sure to transfer
parts from old transmission
if applicable.
Thoroughly clean input shafl and clutch disc splines. Light-
ly lubricate transmission input shaft before installing.
* Be sure bellhousing alignment dowel sleeves are located
correctly. Replace damaged sleeves.
Center rear of transmission in driveshaft tunnel before
tightening transmission support bracket.
NOTE-
In order to avoid difficulties in transmission removal at a fu-
ture time, use washers with Torx-head mounting bolts.
- Reinstall driveshaft. Use new nuts when mounting driveshaff
to transmission/flex disc. See 260 Driveshaft.
- Refill transmission with appropriate lubricant before starting
or towing car. See Transmission fluid service earlier in this
repair group.

/ ~utomatic Transmission
This section covers maintenance and replacement of the
automatic transmission for
E39 models.
Automatic transmission internal repairs are not covered.
Such repairs require special service equipment and knowl-
edge. If it is determined that transmission internal
sewice is
required, consult an authorized BMW dealer about a factory
reconditioned unit or a transmission rebuild.
CAUTION-
ATF does not circulate unless the engine is running. When
towing an automatic transmission vehicle, use a flat bed truck
or raise the rear wheels off the ground.
Special tools
Some special tools are required for the removal and installa-
tion of an automatic transmission on the
E39 BMW models.
While these tools are not absolutely necessary, they are es-
pecially helpful when dealing with the removal and replace-
ment of the torque converter.

I Gearshift Linkage
This repair group covers transmission gearshift and linkage service for both manual and automatic transmission
equipped vehicles.
To gain access to the complete gearshift mechanism it is
necessary to remove the exhaust system and the driveshaft
as described in
180 Exhaust System and 260 Driveshaft.
NOTE-
In models with automatic transmission, the electronic immo-
bilizer
(EWS) prevents starter operation unless the gear po-
sition is Park or Neutral.
Special tools
BMW suggests the use of one special tool in the removal
of the gear shift lever for manual transmission equipped
I I vehicles.
