4 Support subframe from below using BMW special tool 31 2
220 and appropriate shop lift. Remove
subframe mounting
bolts and lower
subframe as far as possible.
Remove oil pan screws (arrows) at cylinder block and trans-
mission bellhousing. Lower and remove oil pan.
NOTE-
If oil pan will not slide backwards, disconnect stabilizer bar
links and lower front axle support further.
If the oil pan does not separate easily from the engine cylin-
der
block, a few taps with a rubber malletshould breakit free.
Do not
pry the oil pan loose.
When installing oil pan: Thoroughly clean all old gasket material from mating sur-
faces and use a new gasket.
Apply a small amount of non-hardening sealer
(3 Bond
12098 or equivalent) to oil pan gasket directly below joints
(arrows) for end cover and front timing case cover. Apply
a bead
3 mm wide by 2 mm high.
Install all oil pan bolts finger tight. Tighten oil pan bolts to-
ward front of engine first, then pan bolts at transmission
end.

Fuel Injection
- Disconnect intake air boot from throttle housing. Unbolt throt-
tle housing and lay aside. It is not necessary to disconnect
throttle cable or electrical harness connectors from throttle housing.
- Remove electrical harness connector from IAT sensor.
- Unclip temperature sensor and remove from intake manifold.
- Installation is reverse of removal. Use a new gasket at throttle
housing.
Throttle position sensor (TPS),
testing and replacing
4 The throttle position sensor (arrow) is located on top of the
throttle valve housing and provides the ECM with a voltage
value that represents throttle position (angle) and rate of
movement.
TheTPS is non-adjustable. If the throttle position sensor is re-
placed, the previous 'learned' TPS settings must be cleared
from the ECM using a BMW-compatible scan tool.
If the throttle position sensor signal is defective, afault code is
stored and the
MILis illuminated when OBD II fault criteria are
exceeded. The ECM still operates the engine using the mass
air flow
(MAF) sensor and engine rpm inputs.
- Check throttle position sensor function by disconnecting har-
ness connector and checking continuity across terminals. If
test results are incorrect,
replace throttle position sensor. The
sensor is non-adjustable.

removing the air filter housing and the throttle housing.
< Disconnect intake air boot from throttle housing. Unbolt throt-
tle body and lay aside. Do not disconnect throttle cable or
electrical harness connectors to throttle body.

Fuel Tank and Fuel Pump
4 Working underneath car, pinch off supply and return fuel hos-
es (arrows), then disconnect hoses from rigid metal lines.
- Remove right rear wheel and wheel housing splash shield.
4 Worlting at right rear wheel housing, loosen hose clamp
(arrow) and disconnect filler pipe from tank.
- Support tank from below. Remove tank strap mounting bolts.
Lower and remove tank, disconnecting right side vent and
other
hoses/electrical connectors as necessary.
Always use new seals, gaskets, O-rings, and hose clamps.
lnspect hoses and replace any that are chafed,
dr~ed out or
cracked.
lnspect heat shield and replace if corroded.
Inspect rubber buffers and
hers on fuel tank, support
straps and on underside of body. Replace rubber parts that
are hardened or damaged.
- After finishing repairs but before starting engine, fill fuel tank
with at least
5 liters (1.5 gallons) of fuel.
CAUTlOI+
The fuelpump will be damaged if run without fuel.
* If the filler neck has been removed from the body, be
sure to reattach the
neck grounding screw (where ap-
plicable). Check electrical resistance between the
ground tab and wheel
hub. The resistance should be
no
hiaher than 0.6f2

Automatic Transmission
- Raise and safely support vehicle.
CA U JIOG
Male sure the car is stable and well supported at all times.
Use a professional automotive lift
orjack stands designed for
the purpose. A floorjack is not adequate support
4 With engine running and selector lever in PARK, remove filler
plug (arrow)
(A5S 360R transmission shown, refer to other
illustrations for location of filler and drain plugs on other
transmissions).
If a small stream of fluid runs out of the filler hole the level
is correct.
If no fluid
leaks out when plug is removed, fluid level is to
low. Add ATF fluid until it starts to overflow.
Install filler plug using a new sealing ring.
Hot ATF can scald. Wear eye protection and protective cloth-
ing andgloves during
the check. If the tmnsmission was over-
filled, hot ATF will spill from the filler hole when the
fill plug is
removed.
ATF, draining and filling
The procedure given here includes removal and installation of
the fluid strainer (filter). Refer to illustrations in Automatic
transmission fluid
pan and strainer.
Remove ATF drain plug
(1) and drain fluid into container.
WARNING-
ATFshould be warm when draining. Hot ATFcan scald. Wear
eye protection, protective clothing and gloves.
Remove transmission pan mounting bolts and remove pan.
Remove pan gasket and clean
gasket sealing surface.
- Pull ATF strainer from transmission pump housing. If strainer
sealing ring remains in pump housing remove using a seal
puller.
- Installation is reverse of removal.
Always replace seal for drain plug and all
gasket(s)
and O-rings.
Clean sump and sump
magnet(s) using a lint-free cloth.
Tighten transmission pan bolts in sequential order.
Using filler plug
(2), fill transmission with approved ATF.
Check fluid level as described earlier.
