Lower oil pan, removing and installing (V-8)
- The V-8 engine is equipped with a 2-piece oil pan. The fas-
teners in
V-8 engine oil pump assembly, including the
sprocket retaining nut, are known to loosen and fall off into
the oil pan. Be sure to install these fasteners with Loctite
O
or equivalent thread locking product and torque to specifica-
tions.
CAUTION-
It is recommended that the oil pump retaining bolts and oil
pump drive sprocket retaining nut tightening torque be
checkedany time the
oilpan is removed.
- Raise car and place securely on jack stands.
WARNING-
Make sure the car is stable and well supported at all times.
Use a professional automotive lift
orjack stands designed for
- Remove splash shield from under engine.
- Drain engine oil
- On cars with automatic transmission, remove ATF cooler line

CAUTION-
Be sure ignition is OFF before disconnecting or reconnecting
DME system components.
NOTE-
Do not confuse the throttle position sensor on the main Nirot-
tle body with the throttle position switch on the secondary
throttle body, where applicable.
- Remove two mounting screws holding sensor to throttle
housing.
- Installation is reverse of removal. Clear adaptation settings
from ECM using BMW-compatible scan tool.
NOTE-
Poor idle quality may be noticeable for a period if the adapta-
tion settings are not cleared after installing new TPS.
ldle speed control valve,
checking and replacing
The idle speed control valve regulates idle speed by redirect-
inq airaround the throttlevalve.The idlespeed control valve is
mounted on the underside of the intake manifold adjacent to
the dipstick tube bracket. Accessing the valve is best accom-
plished by first removing the air filter housing and the throttle
body assembly.
The valve issupplied with
batteryvoltagefrom the ECM relay.
The idle speed control valve incorporates a two-coil rotary ac-
tuator. The ground sides of each coil are pulsed
sirnulta-
neously by the ECM. The duty cycle of each circuit is varied to
achieve the required idle speed.
Afaulty ldle speed control valve sets afault 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.

I Automatic Transmission Automatic transmission fluid (ATF)
The E39 automatic transmission is filled with either Dexron Ill
ATF or Texaco 80728, a life time oil.
CA UTIOI\C
Use only the transmission fluid that is approved for use by
BMW All other fluids will cause non warrantable transmis-
I sion damage.
Mixing different types of transmission fluids will lead to
transmission failure.
NOTE-
The type of transmission lubricant used can be found on a
stickeron the transmission pan. Dexron
111ATF (blacksticker)
reads "ATF-Oil': Special life time oil (green sticker) reads
'Life-Time Oil': If in doubt, consult an authorized
BMW dealer
for alternate fluid use and current information regarding
transmission operating fluids.
ATF level, checking
Check ATF level if there is evidence of a leak, a complaint re-
lated to fluid level or afler transmission repairs.
The automatic transmission is not equipped with a dipstick.
Checking the ATF level requires that the transmission be at
operating temperature during the checking procedure.
NOTE-
Vehicle must be level throughout tests
- Drive vehicle to warm up ATF to operating temperature.
- Connect BMW diagnostic scan tool DiSplus, MoDiC, GTI or
equivalent to determine transmission oil temperature.
ATF level checking
Fluid temperature
30' - 50°C (85' - 120" F)
- With engine running, switch on air conditioning to increase
engine idle speed.
- Apply parking brake.
- While applying foot brake firmly move gear shift selector
lever through
all gear positions, pausing in each gear briefly.
