1985 BMW 3 SERIES Anti lock

0•4Introduction
The E30 3-Series range first became
available in the UK in March 1983, and
continued in production until April 1991, when
the revised E36 3-Series range (not covered
by this manual) was introduced. Convertible
and Touring (Estate) models were introduced
for 1988, and these models have continued in
E30 form to date.
The E28 5-Series models were introduced
in October 1981, and were superseded in
June 1988 by the revised E34 5-Series range,
Touring versions of which became available
from March 1992. Throughout this manual,
E28 models are also referred to as “old-
shape”, while E34 models are designated
“new-shape”.
The models covered by this manual are
equipped with single overhead cam in-line
four- and six-cylinder engines. Early 316 and
518 models are fitted with carburettors, but all
other models are fitted with fuel injection
systems. Transmissions are a five-speed
manual, or three- or four-speed automatic.
The transmission is mounted to the back of
the engine, and power is transmitted to the
fully-independent rear axle through a two-
piece propeller shaft. The final drive unit is
bolted solidly to a frame crossmember, and
drives the rear wheels through driveshaftsequipped with inner and outer constant
velocity joints.
The front suspension is of MacPherson
strut type, with the coil spring/shock absorber
unit making up the upper suspension link. The
rear suspension is made up of coil spring-
over-shock absorber struts, or coil springs
and conventional shock absorbers,
depending on model.
The brakes are disc type at the front, with
either drums or discs at the rear, depending
on model. Servo assistance is standard on all
models. Some later models are equipped with
an Anti-lock Braking System (ABS).
All models are manufactured to fine limits,
and live up to the BMW reputation of quality
workmanship. Although many of the models
covered by this manual appear complex at
first sight, they should present no problems to
the home mechanic.

BMW 320i Saloon (E30)

0•7Anti-theft audio system
Anti-theft audio system
General information
Some models are equipped with an audio
system having an anti-theft feature that will
render the stereo inoperative if stolen. If the
power source to the stereo is cut, the stereo
won’t work even if the power source is
immediately re-connected. If your vehicle is
equipped with this anti-theft system, do not
disconnect the battery or remove the stereo
unless you have the individual code number
for the stereo.
Refer to the owner’s handbook suppliedwith the vehicle for more complete
information on this audio system and its anti-
theft feature.
Unlocking procedure
1Turn on the radio. The word “CODE” should
appear on the display.
2Using the station preset selector buttons,
enter the five-digit code. If you make a
mistake when entering the code, continue
the five-digit sequence anyway. If you hear
a “beep,” however, stop immediately andstart the sequence over again. Note: Yo u
have three attempts to enter the correct
code. If the correct code isn’t entered in
three tries, you’ll have to wait one hour, with
the radio on, before you enter the codes
again.
5Once the code has been entered correctly,
the word “CODE” should disappear from the
display, and the radio should play (you’ll have
to tune-in and enter your preset stations,
however).
6If you have lost your code number, contact
a BMW dealer service department.
Instrument panel language display
On some later models, disconnecting the
battery may cause the instrument panel
display to default to the German language
(this does not usually apply to UK models). If
it is necessary to reset the correct language
after the battery is reconnected, proceed as
follows. With all the doors shut and theignition on (engine not running), press the trip
reset button until the panel displays the
desired language. There are eight languages
available. If you wish to bypass a particular
selection, release the reset button and press
again - this will cause the display to advance
to the next language. Once the correctlanguage has been selected, continue holding
the reset button until the display reads “I.O.
Version 2.0”. Continue holding the button until
it reads “H.P. Version 3.4”, then release the
button.

0•8Roadside Repairs
Jacking and wheel
changing
The jack supplied with the vehicle should
be used only for raising the vehicle when
changing a tyre or placing axle stands under
the frame.
Warning:Never crawl under the
vehicle or start the engine when
this jack is being used as the
only means of support.
When changing a wheel, the vehicle should
be on level ground, with the handbrake firmly
applied, and the wheels chocked. Select
reverse gear (manual transmission) or Park
(automatic transmission). Prise off the hub
cap (if equipped) using the tapered end of the
wheel brace. Loosen the wheel bolts half a
turn, leaving them in place until the wheel is
raised off the ground.
Position the head of the jack under the side
of the vehicle, making sure it engages with thepocket made for this purpose (just behind the
front wheel, or forward of the rear wheel).
Engage the wheel brace handle and turn it
clockwise until the wheel is raised off the
ground. Unscrew the bolts, remove the wheel
and fit the spare.
Refit the wheel bolts and tighten them
finger-tight. Lower the vehicle by turning the
wheel brace anti-clockwise. Remove the jack
and tighten the bolts in a diagonal pattern to
the torque listed in the Chapter 1
Specifications. If a torque wrench is not
available, have the torque checked by a BMW
dealer or tyre fitting specialist as soon as
possible. Refit the hubcap.
Towing
Vehicles with manual transmission can be
towed with all four wheels on the ground, if
necessary. Automatic transmission-equipped
vehicles can only be towed with all fourwheels on the ground providing that the
speed does not exceed 35 mph and the
distance is not over 50 miles, otherwise
transmission damage can result. For
preference, regardless of transmission type,
the vehicle should be towed with the driven
(rear) wheels off the ground.
Proper towing equipment, specifically
designed for the purpose, should be used,
and should be attached to the main structural
members of the vehicle, not to the bumpers or
bumper brackets. Sling-type towing
equipment must notbe used on these
vehicles.
Safety is a major consideration while
towing. The handbrake should be released,
and the transmission should be in neutral. The
steering must be unlocked (ignition switch
turned to position “1”). Remember that
power-assisted steering (where fitted) and the
brake servo will not work with the engine
switched off.
Jacking, towing and wheel changing

engine damage. Conversely, overfilling the
engine (adding oil above the upper mark) may
cause oil-fouled spark plugs, oil leaks, or oil
seal failures.
6To add oil, remove the filler cap located on
the valve cover (see illustrations). After
adding oil, wait a few minutes to allow the
level to stabilise, then pull the dipstick out and
check the level again. Add more oil if required.
Refit the filler cap, tightening it by hand only.
7Checking the oil level is an important
preventive maintenance step. A consistently
low oil level indicates oil leakage through
damaged seals or defective gaskets, or oil
burning (internal leakage past worn rings or
valve guides). The condition of the oil should
also be noted. If the oil looks milky in colour or
has water droplets in it, the cylinder head
gasket may be blown, or the head or block
may be cracked. The engine should be
repaired immediately. Whenever you check
the oil level, slide your thumb and index finger
up the dipstick before wiping off the oil. If you
see small dirt or metal particles clinging to the
dipstick, the oil should be changed (see
Section 6).
Engine coolant
Warning: Do not allow antifreeze
to come in contact with your
skin, or with the vehiclepaintwork. Rinse off spills immediately
with plenty of water. Antifreeze is highly
toxic if ingested. Never leave antifreeze
lying around in an open container, or in
puddles on the floor; children and pets are
attracted by its sweet smell, and may drink
it. Check with local authorities about
disposing of used antifreeze. Local
collection centres may exist, to see that
antifreeze is disposed of safely.
8All vehicles covered by this manual are
equipped with a pressurised coolant recovery
system. On most models, a white plastic
expansion tank (or coolant reservoir) located
in the engine compartment is connected by a
hose to the radiator. As the engine heats up
during operation, the expanding coolant fills
the tank. As the engine cools, the coolant is
automatically drawn back into the cooling
system, to maintain the correct level.
9The coolant level in the reservoir (see
illustrations)should be checked regularly.
Add a 40%/60% mixture of ethylene glycol-
based antifreeze to water (see illustration).
Warning: Do not remove the
expansion tank cap or radiator
cap to check the coolant level,
unless the engine is completely
cold! The level in the reservoir varies with
the temperature of the engine. When the
engine is cold, the coolant level should beabove the LOW mark on the reservoir.
Once the engine has warmed up, the level
should be at or near the FULL mark. If it
isn’t, allow the engine to cool, then remove
the cap from the reservoir.
10Drive the vehicle and recheck the coolant
level. If only a small amount of coolant is
required to bring the system up to the proper
level, plain water can be used. However,
repeated additions of water will dilute the
antifreeze. In order to maintain the proper
ratio of antifreeze and water, always top-up
the coolant level with the correct mixture.
11If the coolant level drops consistently,
there must be a leak in the system. Inspect
the radiator, hoses, filler cap, drain plugs and
water pump (see Section 29). If no leaks are
noted, have the expansion tank cap or
radiator cap pressure-tested by a BMW
dealer.
12If you have to remove the cap, wait until
the engine has cooled completely, then wrap
a thick cloth around the cap and turn it to the
first stop. If coolant or steam escapes, let the
engine cool down longer, then remove the
cap.
13Check the condition of the coolant as
well. It should be relatively clear. If it’s brown
or rust-coloured, the system should be
drained, flushed and refilled. Even if the
coolant appears to be normal, the corrosion

6 Engine oil and filter change
1
Warning: Prolonged skin contact
with used engine oil is
hazardous. Use a barrier cream
and wear gloves during this procedure.
Change out of oil-soaked clothing
immediately.
1Make sure that you have all the necessary
tools before you begin this procedure (see
illustration). You should also have plenty of rags
or newspapers handy for mopping up oil spills2Start the engine and allow it to reach
normal operating temperature - oil and sludge
will flow more easily when warm. If new oil, a
filter or tools are needed, use the vehicle to go
and get them, thus warming up the engine oil
at the same time.
3Park on a level surface, and switch off the
engine when it’s warmed up. Remove the oil
filler cap from the valve cover.
4Access to the oil drain plug and filter will be
improved if the vehicle can be lifted on a hoist,
driven onto ramps, or supported by axle
stands.
Warning: DO NOT work under a
vehicle supported only by a
hydraulic or scissors-type jack -
always use axle stands!
5If you haven’t changed the oil on this
vehicle before, get under it, and locate the
drain plug and the oil filter. Note that on some
engines, the oil filter is located on the top left-
hand side of the engine. The exhaust
components will be hot as you work, so note
how they are routed to avoid touching them.
6Being careful not to touch the hot exhaust
components, position a drain pan under the
plug in the bottom of the engine.
7Clean the area around the plug, then
remove the plug (see illustration). It’s a good
idea to wear a rubber glove while unscrewing
the plug the final few turns, to avoid being
scalded by hot oil. Hold the drain plug againstthe threads as you unscrew it, then pull it
away from the drain hole suddenly. This will
place your arm out of the way of the hot oil, as
well as reducing the chances of dropping the
drain plug into the drain pan.
8It may be necessary to move the drain pan
slightly as oil flow slows to a trickle. Inspect
the old oil for the presence of metal particles,
which could give early warning of engine
wear.
9After all the oil has drained, wipe off the
drain plug with a clean rag. Any small metal
particles clinging to the plug would
immediately contaminate the new oil.
10Refit the plug and tighten it securely. Use
a new washer if necessary.
11Move the drain pan into position under the
oil filter.
Canister-type oil filter
12Loosen the spin-off type oil filter by
turning it anti-clockwise with a filter spanner.
Any standard filter spanner will work.
13Sometimes the spin-off type oil filter is
screwed on so tightly that it can’t be easily
loosened. If it is, punch a metal bar or long
screwdriver directly through it, and use it as a
T-bar to turn the filter. Be prepared for oil to
spurt out of the canister as it’s punctured.
14Once the filter is loose, use your hands to
unscrew it from the block. Just as the filter is
detached from the block, immediately tilt the
open end up to prevent oil inside the filter
from spilling out.
15Using a clean rag, wipe off the mounting
surface on the block. Also, make sure that
none of the old sealing ring remains stuck to
the mounting surface. It can be removed with
a scraper if necessary.
16Compare the old filter with the new one,
to make sure they are the same type. Smear
some engine oil on the rubber sealing ring of
the new filter, and screw it into place (see
illustration). Overtightening the filter will
damage the sealing ring, so don’t use a filter
spanner. Most filter manufacturers
recommend tightening the filter by hand only.
Normally, they should be tightened three-
quarters of a turn after the sealing ring
contacts the block, but be sure to follow the
directions on the filter or container.
6.1 These tools are required when
changing the engine oil and filter
1 Drain pan- It should be fairly shallow in
depth, but wide enough to prevent spills
2 Rubber gloves- When removing the drain
plug and filter, you will get oil on your
hands (the gloves will prevent burns)
3 Socket bar - Sometimes the oil drain plug
is tight, and a long bar is needed to loosen
it. The correct-size ring spanner may work
just as well
4 Socket- To be used with the bar or a
ratchet (must be the correct size to fit the
drain plug - six-point preferred)
5 Filter spanner - This is a metal band-type
spanner, which requires clearance around
the filter to be effective. This tool is not
required on all engines.
6 Filter spanner- This type fits on the bottom
of the filter and can be turned with a ratchet
or breaker bar (different-size spanners are
available for different types of filters) This
tool is not required on all engines.
6.7 Using a ring spanner to remove the oil
drain plug
6.16 Lubricate the oil filter sealing ring
with clean engine oil before refitting the
filter on the engine
Frequent oil changes are the
most important preventive
maintenance procedures that
can be done by the home
mechanic. As engine oil ages, it
becomes diluted and contaminated,
which leads to premature engine wear.

Cartridge-type oil filter
17Some models are equipped with a
cartridge-type oil filter. Unscrew the bolt,
remove the cover, and lift the filter out (see
illustrations).
18Compare the new cartridge with the old
one, to make sure they are the same type,
then lower it into the housing.
19Using a clean rag, wipe off the mounting
surface of the housing and cover. If necessary,
renew the rubber O-ring (see illustration).
Smear some clean oil on the O-ring and refit
the cover and bolt. Tighten the bolt securely.
All models
20Remove all tools and materials from under
the vehicle, being careful not to spill the oil
from the drain pan, then lower the vehicle.
21Add new oil to the engine through the oil
filler cap in the valve cover. Use a funnel to
prevent oil from spilling onto the top of the
engine. Pour the specified quantity of fresh oil
into the engine. Wait a few minutes to allow the
oil to drain into the sump, then check the level
on the dipstick (see Section 4 if necessary). If
the oil level is correct, refit the filler cap.
22Start the engine and run it for about a
minute. The oil pressure warning light may
take a few seconds to go out while the new
filter fills with oil; don’t rev the engine while
the light is on. While the engine is running,
look under the vehicle, and check for leaks at
the sump drain plug and around the oil filter. Ifeither one is leaking, stop the engine and
tighten the plug or filter slightly.
23Wait a few minutes, then recheck the level
on the dipstick. Add oil as necessary.
24During the first few days after an oil
change, make it a point to check frequently
for leaks and proper oil level.
25The old oil drained from the engine cannot
be re-used in its present state, and should be
discarded. Oil reclamation centres and some
service stations will accept the oil, which can
be recycled. After the oil has cooled, it can be
transferred into a container for transport to a
disposal site.
7 Power steering fluid level
check
1
1Check the power steering fluid level
periodically to avoid steering system
problems, such as damage to the pump.
Proceed as follows.Caution: Do not hold the steering
wheel against either stop (full-left
or full-right lock) for more than
five seconds. If you do, the power
steering pump could be damaged.
2On some models, the power steering fluid
reservoir is located on the left side of the
engine compartment, and has a twist-off cap
with an integral fluid level dipstick (see
illustration). Other models use a hydraulic
power steering and brake servo system which
combines the fluid in one reservoir, located at
the right rear corner of the engine
compartment.
3Park the vehicle on level ground, and apply
the handbrake.
4On models with a fluid dipstick, run the
engine until it has reached normal operating
temperature. With the engine at idle, turn the
steering wheel back and forth several times to
get any air out of the steering system. Switch
off the engine, remove the cap by turning it
anti-clockwise, wipe the dipstick clean, and
refit the cap. Remove the cap again, and note
the fluid level. It must be between the two
lines (see illustration).
5On hydraulic servo models, pump the brake
pedal about ten times or until the pedal is firm.
Remove the nut, lift the cap off, and make
sure the fluid is within 6.0 mm of the top of the
reservoir.
6Add small amounts of fluid until the level is
correct (see illustration).

5With the engine cool, remove the HT lead
from one spark plug. Do this by grabbing the
connector at the end of the wire, not the lead
itself (see illustration). Sometimes it is
necessary to use a twisting motion while the
connector and HT lead are pulled free.
6If compressed air is available, use it to blow
any dirt or foreign material away from the
spark plug area. A common bicycle pump will
also work. The idea here is to eliminate the
possibility of debris falling into the cylinder as
the spark plug is removed.
7Place the spark plug socket over the plug,
and remove it from the engine by turning it
anti-clockwise (see illustration).
8Compare the spark plug with those shown
in the accompanying photos to get an
indication of the overall running condition of
the engine.
9Apply a little copper-based anti-seize
compound to the threads of the new spark
plug. Locate the plug into the head, screwing
it in with your fingers until it no longer turns,
then tighten it with the socket. If available, use
a torque wrench to tighten the plug to ensure
that it is seated correctly. The correct torque
figure is included in this Chapter’s Specifi-
cations.10Before pushing the HT lead onto the end of
the plug, inspect it as outlined in Section 15.
11Attach the HT lead to the new spark plug,
again using a twisting motion on the
connector until it is firmly seated on the spark
plug.
12Follow the above procedure for the
remaining spark plugs, renewing them one at
a time to prevent mixing up the spark plug HT
leads.
15 Spark plug HT leads,
distributor cap and rotor -
check and renewal
1
1The spark plug HT leads should be checked
at the recommended intervals, and whenever
new spark plugs are fitted in the engine.
2Begin this procedure by making a visual
check of the spark plug HT leads while the
engine is running. In a darkened garage (make
sure there is ventilation) start the engine and
observe each HT lead. Be careful not to come
into contact with any moving engine parts. If
there is a break in the wire, you will see arcing
or a small spark at the damaged area. If arcing
is noticed, make a note to obtain new HT
leads, then allow the engine to cool.
3Disconnect the battery negative cable.
Caution: If the radio in your
vehicle is equipped with an anti-
theft system, make sure you have
the correct activation code
before disconnecting the battery. Note: If, after connecting the battery, the
wrong language appears on the instrument
panel display, refer to page 0-7 for the
language resetting procedure.
4The HT leads should be inspected one at a
time to prevent mixing up the firing order,
which is essential for proper engine operation.
5Disconnect the HT lead from the spark
plug. Do not pull on the lead itself, only on the
connector.
6Inspect inside the connector for corrosion,
which will look like a white crusty powder.
Push the HT lead and connector back onto
the end of the spark plug. It should be a tight
fit on the plug end. If it is not, remove the lead
and use pliers to carefully crimp the metal
terminal inside the connector until it fits
securely on the end of the spark plug.
7Using a clean rag, wipe the entire length of
the HT lead to remove any built-up dirt and
grease. Once the lead is clean, check for
burns, cracks and other damage. Do not bend
the lead excessively, since the conductor
might break.
8Disconnect the HT lead from the distributor.
Again, pull only on the connector. Check for
corrosion and a tight fit in the same manner as
the spark plug end. Renew the HT lead in the
distributor if necessary.
9Check the remaining spark plug HT leads,
making sure they are securely fastened at the
distributor and spark plug when the check is
complete.
10If new spark plug HT leads are required,
purchase a set for your specific engine model.
Lead sets are available pre-cut, with the
connectors already fitted. Remove and renew
the HT leads one at a time, to avoid mix-ups
in the firing order.
11Loosen the screws or detach the clips and
remove the distributor cap (see illustration).
Remove the screws (if applicable) and pull the
rotor off the shaft (see illustration). Check the
distributor cap and rotor for wear. Look for
cracks, carbon tracks and worn, burned or
loose contacts (see illustrations). Renew the
cap and rotor if defects are found. It is
common practice to fit a new cap and rotor
whenever new spark plug HT leads are fitted.
When fitting a new cap, remove the HT leads
from the old cap one at a time, and attach

Every 12 000 miles
Where there might be difficulty in
inserting the spark plugs into the spark
plug holes, or the possibility of cross-
threading them into the head, a short
piece of rubber or plastic tubing can be
fitted over the end of the spark plug.
The flexible tubing will act as a universal
joint to help align the plug with the plug
hole, and should the plug begin to
cross-thread, the hose will slip on the
spark plug, preventing thread damage.

Flushing
7Once the system is completely drained,
flush the radiator with fresh water from a
garden hose until the water runs clear at the
drain or bottom hose. If the radiator is
severely corroded, damaged or leaking, it
should be removed (see Chapter 3) and taken
to a radiator repair specialist.
8Flushing in this way will remove sediments
from the radiator, but will not remove rust and
scale from the engine and cooling tube
surfaces. These deposits can be removed by
using a chemical cleaner. Follow the
procedure outlined in the cleaner
manufacturer’s instructions. Remove the
cylinder block drain plug before flushing the
engine.
9On models so equipped, remove the
overflow hose from the coolant recovery
reservoir. Drain the reservoir and flush it with
clean water, then reconnect the hose.
Refilling
10Tighten the radiator drain plug, or
reconnect the radiator bottom hose. Refit and
tighten the cylinder block drain plug.
Four-cylinder engines
11Slowly add new coolant (a 40%/60%
mixture of antifreeze to water) to the radiator
until it is full. Add coolant to the reservoir up
to the lower mark.
12Leave the radiator cap off, and run the
engine in a well-ventilated area until the
thermostat opens (coolant will begin flowing
through the radiator, and the upper radiator
hose will become hot).
13Turn the engine off, and let it cool. Add
more coolant mixture to bring the coolant
level back up to the lip on the radiator filler
neck. On the M40 engine, unscrew the bleed
screw from the top of the radiator, and add
coolant until it comes out of the bleed screw
hole. Refit and tighten the bleed screw.
14Squeeze the upper radiator hose to expel
air, then add more coolant mixture if
necessary. Refit the radiator cap.
15Start the engine, allow it to reach normal
operating temperature, and check for leaks.
Six-cylinder engines
16Loosen the bleed screw in the thermostat
housing (see illustration)
17Fill the radiator with a 40%/60% solution
of antifreeze and water until it comes out of
the bleed screw opening. Tighten the bleed
screw.
18Refit the radiator cap, and run the engine
until the thermostat opens (the upper radiator
hose will become hot). Slowly loosen the
bleed screw until no bubbles emerge, then
tighten the screw.
19Repeat the procedure until the air is bled
from the system.
30 Fuel filter renewal
1
Warning: Fuel is extremely
flammable, so take extra
precautions when you work on
any part of the fuel system. Don’t
smoke, or allow open flames or bare light
bulbs, near the work area. Don’t work in a
garage where a natural gas-type appliance
(such as a water heater or clothes dryer)
with a pilot light is present. If you spill any
fuel on your skin, rinse it off immediately
with soap and water. When you perform
any kind of work on the fuel system, wear
safety glasses, and have a fire
extinguisher on hand.
1On fuel injection engines, depressurise the
fuel system (see Chapter 4).
2The fuel filter is located in the engine
compartment on the bulkhead, or under the
vehicle adjacent to the fuel tank.
3Because on some models the filter is
located adjacent to the starter motor, fuel
could leak onto the electrical connections. For
safety reasons, therefore, disconnect the
battery negative cable before beginning work.
Caution: If the radio in your
vehicle is equipped with an anti-
theft system, make sure you have
the correct activation code
before disconnecting the battery.Note: If, after connecting the battery, the
wrong language appears on the instrument
panel display, refer to page 0-7 for the
language resetting procedure.
