terminals and cable clamps after they are
assembled.
9Make sure that the battery carrier is in good
condition, and that the hold-down clamp bolt
is tight. If the battery is removed (see Chap-
ter 5 for the removal and refitting procedure),
make sure that no parts remain in the bottom
of the carrier when it’s refitted. When refitting
the hold-down clamp, don’t overtighten the
bolt.
10Corrosion on the carrier, battery case and
surrounding areas can be removed with a
solution of water and baking soda. Apply the
mixture with a small brush, let it work, then
rinse it off with plenty of clean water.
11Any metal parts of the vehicle damaged
by corrosion should be coated with a zinc-
based primer, then painted.
12Additional information on the battery and
jump starting can be found in Chapter 5 and
the front of this manual.
Charging
Note: The manufacturer recommends the
battery be removed from the vehicle for
charging, because the gas which escapes
during this procedure can damage the paint or
interior, depending on the location of the
battery. Fast charging with the battery cables
connected can result in damage to the
electrical system.
13Remove all of the cell caps (if applicable),
and cover the holes with a clean cloth to
prevent spattering electrolyte. Disconnect thebattery negative cable, and connect the
battery charger leads to the battery posts
(positive to positive, negative to negative),
then plug in the charger. Make sure it is set at
12 volts if it has a selector switch.
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.
14If you’re using a charger with a rate higher
than two amps, check the battery regularly
during charging to make sure it doesn’t
overheat. If you’re using a trickle charger, you
can safely let the battery charge overnight
after you’ve checked it regularly for the first
couple of hours. Where a maintenance-free
battery is fitted, special precautions may be
necessary when charging it (for example, the
charge rate is normally very low). There may
be a warning label on the battery, but if not,
consult a BMW dealer or auto-electrician.
15If the battery has removable cell caps,
measure the specific gravity with a
hydrometer every hour during the last few
hours of the charging cycle. Hydrometers are
available inexpensively from car accessory
shops - follow the instructions that come with
the hydrometer. Consider the battery charged
when there’s no change in the specific gravity
reading for two hours, and the electrolyte in
the cells is gassing (bubbling) freely. The
specific gravity reading from each cell should
be very close to the others. If not, the battery
probably has a bad cell(s), and a new one
should be fitted.
16Some maintenance-free (sealed) batteries
have built-in hydrometers on the top,
indicating the state of charge by the colour
displayed in the hydrometer window.
Normally, a bright-coloured hydrometer
indicates a full charge, and a dark hydrometer
indicates the battery still needs charging.
Check the battery manufacturer’s instructions
to be sure you know what the colours mean.17If the battery is sealed and has no built-in
hydrometer, you can connect a digital
voltmeter across the battery terminals to
check the charge. A fully-charged battery
should read 12.6 volts or higher.
18Further information on the battery and
jump starting can be found in Chapter 5 and
at the front of this manual.
14 Spark plug check and
renewal
1
1Before beginning, obtain the necessary
tools, which will include a spark plug socket
and a set of feeler blades. Special spark plug
gap gauges can be obtained from certain
spark plug manufacturers (see illustration).
2The best procedure to follow when
renewing the spark plugs is to purchase the
new spark plugs beforehand, adjust them to
the proper gap, and then renew each plug one
at a time. When buying the new spark plugs, it
is important to obtain the correct plugs for
your specific engine. This information can be
found in the Specifications section in the front
of this Chapter.
3With the new spark plugs at hand, allow the
engine to cool completely before attempting
plug removal. During this time, each of the
new spark plugs can be inspected for defects
and the gaps can be checked.
4The gap is checked by inserting the proper
thickness gauge between the electrodes at the
tip of the plug (see illustration). The gap
between the electrodes should be the same as
that given in the Specifications. The wire
should just touch each of the electrodes. If the
gap is incorrect, use the notched adjuster to
bend the curved side of the electrode slightly
until the proper gap is achieved (see
illustration). Note: When adjusting the gap of a
new plug, bend only the base of the earth
electrode, do not touch the tip. If the earth
electrode is not exactly over the centre
electrode, use the notched adjuster to align the
two. Check for cracks in the porcelain insulator,
indicating the spark plug should not be used.
1•17
14.4b To change the gap, bend the earth
electrode only, as indicated by the arrows,
and be very careful not to crack or chip the
porcelain insulator surrounding the centre
electrode14.4a Spark plug manufacturers
recommend using a wire-type gauge when
checking the gap - if the wire does not
slide between the electrodes with a slight
drag, adjustment is required
14.1 Tools required for changing spark
plugs
1 Spark plug socket- This will have special
padding inside to protect the spark plug’s
porcelain insulator
2 Torque wrench - Although not mandatory,
using this tool is the best way to ensure the
plugs are tightened properly
3 Ratchet - Standard hand tool to fit the
spark plug socket
4 Extension - Depending on model and
accessories, you may need special
extensions and universal joints to reach one
or more of the plugs
5 Spark plug gap gauge- This gauge for
checking the gap comes in a variety of
styles. Make sure the gap for your engine is
included. Feeler blades may be used
instead
1
Every 12 000 miles
reading should be between 400 and 500 mA.
Adjust the valve if the current reading is not as
specified. Note: The idle air stabiliser current
will fluctuate between 400 and 1100 mA if the
engine is too cold, if the coolant temperature
sensor is faulty, if there is an engine vacuum
leak, or if electrical accessories are on.
25If there is no current reading, have the idle
speed control unit (under the facia) checked
by a BMW dealer or other specialist.
26On three-wire valves, check for voltage at
the electrical connector. With the ignition on,
there should be battery voltage present at the
centre terminal (see illustration). There
should be about 10 volts between the centre
terminal and each of the outer terminals.
27If there is no voltage reading, have the idle
speed control unit (early models) or the ECU
(later models) checked by a dealer service
department or other specialist.
Adjustment (early models only)
28With the ignition switched off, connect a
tachometer in accordance with the equipment
manufacturer’s instructions.
29Make sure the ignition timing is correct
(see Chapter 5).
30Connect an ammeter to the valve as
described in paragraph 13.
31With the engine running, the current draw
should be 450 to 470 mA at 700 to 750 rpm.
32If the control current is not correct, turn
the adjusting screw until it is within the
specified range. Note: Turn the idle air bypass
screw clockwise to increase the current, or
anti-clockwise to decrease the current.
Renewal
33Remove the electrical connector and the
bracket from the idle air stabiliser valve.
Remove the valve, disconnecting the hoses.
34Refitting is the reverse of removal.
22 Exhaust system servicing-
general information
Warning: Inspect or repair
exhaust system components only
when the system is completely
cool. When working under the
vehicle, make sure it is securely
supported.
Silencer and pipes
1The exhaust system consists of the exhaust
manifold, catalytic converter, silencers, and all
connecting pipes, brackets, mountings (see
illustration)and clamps. The exhaust system
is attached to the body with brackets and
rubber mountings. If any of the parts are
improperly fitted, excessive noise and
vibration may be transmitted to the body.
2Inspect the exhaust system regularly. Look
for any damaged or bent parts, open seams,
holes, loose connections, excessive
corrosion, or other defects which could allow
exhaust fumes to enter the vehicle. Generally,
deteriorated exhaust system components
cannot be satisfactorily repaired; they should
be renewed.3If the exhaust system components are
extremely corroded or rusted together, it may
be necessary to cut off the old components
with a hacksaw. Be sure to wear safety
goggles to protect your eyes from metal
chips, and wear work gloves to protect your
hands.
4Here are some simple guidelines to follow
when repairing the exhaust system:
a) Work from the back to the front of the
vehicle when removing exhaust system
components.
b) Apply penetrating oil to the exhaust
system nuts and bolts to make them
easier to remove.
c) Use new gaskets, mountings and clamps
when fitting exhaust system components.
d) Apply anti-seize compound to the threads
of all exhaust system nuts and bolts
during reassembly.
e) Be sure to allow sufficient clearance
between newly-fitted parts and all points
on the underbody, to avoid overheating
the floorpan, and possibly damaging the
interior carpet and insulation. Pay
particularly close attention to the catalytic
converters and heat shields. Also, make
sure that the exhaust will not come into
contact with suspension parts, etc.
Catalytic converter
5Although the catalytic converter is an
emissions-related component, it is discussed
here because, physically, it’s an integral part
of the exhaust system. Always check the
converter whenever you raise the vehicle to
inspect or service the exhaust system.
6Raise and support the vehicle.
7Inspect the catalytic converter for cracks or
damage.
8Check the converter connections for
tightness.
9Check the insulation covers welded onto the
catalytic converter for damage or a loose fit.
Caution: If an insulation cover is
dented so that it touches the
converter housing inside,
excessive heat may be
transferred to the floor.
10Start the engine and run it at idle speed.
Check all converter connections for exhaust
gas leakage.

1 General information
These models feature an all-steel welded
construction, where the floorpan and body
components are welded together and
attached to separate front and rear subframe
assemblies. Certain components are
particularly vulnerable to accident damage,
and can be unbolted and repaired or renewed.
Among these parts are the body mouldings,
bumpers, bonnet, doors, tailgate, and all
glass.
Only general body maintenance procedures
and body panel repair procedures within the
scope of the do-it-yourselfer are included in
this Chapter.
2 Bodywork and underframe-
maintenance
1
The general condition of a vehicle’s
bodywork is the one thing that significantly
affects its value. Maintenance is easy, but
needs to be regular. Neglect, particularly after
minor damage, can lead quickly to further
deterioration and costly repair bills. It is
important also to keep watch on those parts
of the vehicle not immediately visible, for
instance the underside, inside all the wheelarches, and the lower part of the engine
compartment.
The basic maintenance routine for the
bodywork is washing - preferably with a lot of
water, from a hose. This will remove all the
loose solids which may have stuck to the
vehicle. It is important to flush these off in
such a way as to prevent grit from scratching
the finish. The wheel arches and underframe
need washing in the same way, to remove any
accumulated mud, which will retain moisture
and tend to encourage rust. Paradoxically
enough, the best time to clean the underframe
and wheel arches is in wet weather, when the
mud is thoroughly wet and soft. In very wet
weather, the underframe is usually cleaned of
large accumulations automatically, and this is
a good time for inspection.
Periodically, except on vehicles with a wax-
based underbody protective coating, it is a
good idea to have the whole of the
underframe of the vehicle steam-cleaned,
engine compartment included, so that a
thorough inspection can be carried out to see
what minor repairs and renovations are
necessary. Steam-cleaning is available at
many garages, and is necessary for the
removal of the accumulation of oily grime,
which sometimes is allowed to become thick
in certain areas. If steam-cleaning facilities are
not available, there are some excellent grease
solvents available which can be brush-
applied; the dirt can then be simply hosed off.
Note that these methods should not be usedon vehicles with wax-based underbody
protective coating, or the coating will be
removed. Such vehicles should be inspected
annually, preferably just prior to Winter, when
the underbody should be washed down, and
any damage to the wax coating repaired.
Ideally, a completely fresh coat should be
applied. It would also be worth considering
the use of such wax-based protection for
injection into door panels, sills, box sections,
etc, as an additional safeguard against rust
damage, where such protection is not
provided by the vehicle manufacturer.
After washing paintwork, wipe off with a
chamois leather to give an unspotted clear
finish. A coat of clear protective wax polish will
give added protection against chemical
pollutants in the air. If the paintwork sheen has
dulled or oxidised, use a cleaner/polisher
combination to restore the brilliance of the
shine. This requires a little effort, but such
dulling is usually caused because regular
washing has been neglected. Care needs to be
taken with metallic paintwork, as special non-
abrasive cleaner/polisher is required to avoid
damage to the finish. Always check that the
door and ventilator opening drain holes and
pipes are completely clear, so that water can
be drained out. Brightwork should be treated in
the same way as paintwork. Windscreens and
windows can be kept clear of the smeary film
which often appears, by the use of proprietary
glass cleaner. Never use any form of wax or
other body or chromium polish on glass.

3 Interior trim- maintenance
1
Interior trim panels can be kept clean by
wiping with a damp cloth. If they do become
stained (which can be more apparent on light-
coloured trim), use a little liquid detergent and
a soft nail brush to scour the grime out of the
grain of the material. Do not forget to keep the
headlining clean in the same way. After
cleaning, application of a high-quality rubber
and vinyl protector will help prevent oxidation
and cracks. The protector can also be applied
to weatherstrips, vacuum lines and rubber
hoses, which often fail as a result of chemical
degradation, and to the tyres.
4 Upholstery and carpets-
maintenance
1
Mats and carpets should be brushed or
vacuum-cleaned regularly, to keep them free
of grit. If they are badly stained, remove them
from the vehicle for scrubbing or sponging,
and make quite sure they are dry before
refitting. Seats and interior trim panels can be
kept clean by wiping with a damp cloth. If they
do become stained (which can be more
apparent on light-coloured upholstery), use a
little liquid detergent and a soft nail brush to
scour the grime out of the grain of the
material. Do not forget to keep the headlining
clean in the same way as the upholstery.
When using liquid cleaners inside the vehicle,
do not over-wet the surfaces being cleaned.
Excessive damp could get into the seams and
padded interior, causing stains, offensive
odours or even rot.
5 Bodywork repair-
minor damage
3
Note:For more detailed information about
bodywork repair, Haynes Publishing produce
a book by Lindsay Porter called “The Car
Bodywork Repair Manual”. This incorporates
information on such aspects as rust treatment,
painting and glass-fibre repairs, as well as
details on more ambitious repairs involving
welding and panel beating.
Repairs of minor scratches in
bodywork
If the scratch is very superficial, and does
not penetrate to the metal of the bodywork,
repair is very simple. Lightly rub the area of
the scratch with a paintwork renovator, or a
very fine cutting paste, to remove loose paint
from the scratch, and to clear the surrounding
bodywork of wax polish. Rinse the area with
clean water.
Apply touch-up paint to the scratch using a
fine paint brush; continue to apply fine layers
of paint until the surface of the paint in the
scratch is level with the surrounding
paintwork. Allow the new paint at least two
weeks to harden, then blend it into the
surrounding paintwork by rubbing the scratch
area with a paintwork renovator or a very fine
cutting paste. Finally, apply wax polish.
Where the scratch has penetrated right
through to the metal of the bodywork, causing
the metal to rust, a different repair technique
is required. Remove any loose rust from the
bottom of the scratch with a penknife, then
apply rust-inhibiting paint to prevent the
formation of rust in the future. Using a rubber
or nylon applicator, fill the scratch with
bodystopper paste. If required, this paste can
be mixed with cellulose thinners to provide a
very thin paste which is ideal for filling narrow
scratches. Before the stopper-paste in the
scratch hardens, wrap a piece of smooth
cotton rag around the top of a finger. Dip the
finger in cellulose thinners, and quickly sweep
it across the surface of the stopper-paste in
the scratch; this will ensure that the surface of
the stopper-paste is slightly hollowed. The
scratch can now be painted over as described
earlier in this Section.
Repairs of dents in bodywork
When deep denting of the vehicle’s
bodywork has taken place, the first task is to
pull the dent out, until the affected bodywork
almost attains its original shape. There is little
point in trying to restore the original shape
completely, as the metal in the damaged area
will have stretched on impact, and cannot be
reshaped fully to its original contour. It is
better to bring the level of the dent up to a
point which is about 3 mm below the level of
the surrounding bodywork. In cases where the
dent is very shallow anyway, it is not worth
trying to pull it out at all. If the underside of the
dent is accessible, it can be hammered out
gently from behind, using a mallet with a
wooden or plastic head. Whilst doing this,
hold a suitable block of wood firmly against
the outside of the panel, to absorb the impact
from the hammer blows and thus prevent a
large area of the bodywork from being
“belled-out”.
Should the dent be in a section of the
bodywork which has a double skin, or some
other factor making it inaccessible from
behind, a different technique is called for. Drill
several small holes through the metal insidethe area - particularly in the deeper section.
Then screw long self-tapping screws into the
holes, just sufficiently for them to gain a good
purchase in the metal. Now the dent can be
pulled out by pulling on the protruding heads
of the screws with a pair of pliers.
The next stage of the repair is the removal
of the paint from the damaged area, and from
an inch or so of the surrounding “sound”
bodywork. This is accomplished most easily
by using a wire brush or abrasive pad on a
power drill, although it can be done just as
effectively by hand, using sheets of abrasive
paper. To complete the preparation for filling,
score the surface of the bare metal with a
screwdriver or the tang of a file, or
alternatively, drill small holes in the affected
area. This will provide a really good “key” for
the filler paste.
To complete the repair, see the Section on
filling and respraying.
Repairs of rust holes or gashes
in bodywork
Remove all paint from the affected area,
and from an inch or so of the surrounding
“sound” bodywork, using an abrasive pad or a
wire brush on a power drill. If these are not
available, a few sheets of abrasive paper will
do the job most effectively. With the paint
removed, you will be able to judge the severity
of the corrosion, and therefore decide
whether to renew the whole panel (if this is
possible) or to repair the affected area. New
body panels are not as expensive as most
people think, and it is often quicker and more
satisfactory to fit a new panel than to attempt
to repair large areas of corrosion.
Remove all fittings from the affected area,
except those which will act as a guide to the
original shape of the damaged bodywork (eg
headlight shells etc). Then, using tin snips or a
hacksaw blade, remove all loose metal and
any other metal badly affected by corrosion.
Hammer the edges of the hole inwards, in
order to create a slight depression for the filler
paste.
Wire-brush the affected area to remove the
powdery rust from the
surface of the remaining metal. Paint the
affected area with rust-inhibiting paint, if the
back of the rusted area is accessible, treat
this also.
Before filling can take place, it will be
necessary to block the hole in some way. This
can be achieved by the use of aluminium or
plastic mesh, or aluminium tape.
Aluminium or plastic mesh, or glass-fibre
matting, is probably the best material to use
for a large hole. Cut a piece to the
approximate size and shape of the hole to be
filled, then position it in the hole so that its
edges are below the level of the surrounding
bodywork. It can be retained in position by
several blobs of filler paste around its
periphery.
Aluminium tape should be used for small or
very narrow holes. Pull a piece off the roll, trim

gets wet accidentally, it is
worthwhile taking some
trouble to dry it out properly,
particularly where carpets are involved.

Buying spare parts & vehicle identification numbers
Buying spare parts
Spare parts are available from many
sources; for example, BMW garages, other
garages and accessory shops, and motor
factors. Our advice regarding spare part
sources is as follows.
Officially-appointed BMW garages- This is
the best source for parts which are peculiar to
your vehicle, and which are not generally
available (eg complete cylinder heads, internal
transmission components, badges, interior
trim etc). It is also the only place at which you
should buy parts if the vehicle is still under
warranty. To be sure of obtaining the correct
parts, it will be necessary to give the storeman
the full Vehicle Identification Number, and if
possible, to take the old parts along for
positive identification. Many parts are
available under a factory exchange scheme -
any parts returned should always be clean. It
obviously makes good sense to go straight to
the specialists on your vehicle for this type of
part, as they are best equipped to supply you.
Other garages and accessory shops- These
are often very good places to buy materials
and components needed for the maintenance
of your vehicle (eg oil filters, spark plugs,
bulbs, drivebelts, oils and greases, touch-up
paint, filler paste, etc). They also sell general
accessories, usually have convenient opening
hours, charge lower prices, and can often be
found not far from home.
Motor factors- Good factors will stock all
the more important components which wearout comparatively quickly (eg exhaust
systems, brake pads, seals and hydraulic
parts, clutch components, bearing shells,
pistons, valves etc). Motor factors will often
provide new or reconditioned components on
a part-exchange basis - this can save a
considerable amount of money.
Vehicle identification
numbers
Modifications are a continuing and
unpublicised process in vehicle manufacture,
quite apart from major model changes. Spare
parts manuals and lists are compiled upon a
numerical basis, the appropriate identification
number or code being essential to correct
identification of the component concerned.When ordering spare parts, always give as
much information as possible. Quote the
vehicle model, year of manufacture, Vehicle
Identification Number and engine numbers, as
appropriate.
The Vehicle Identification Number (VIN)is
located on the right-hand front wheel arch
next to the front suspension strut upper
mounting, on the driver’s door, and on a plate
on top of the facia, just inside the windscreen
(see illustrations).
The engine number is stamped on a
machined face on the left-hand side of the
cylinder block, near the base of the oil level
dipstick tube.
The body numberis located on the seam
between the left-hand front wing and inner
panel.
The VIN (arrowed) is stamped on the
bulkheadThe VIN is also present on the edge of the
driver’s door
