General
0 GENERAL, MAINTENANCE covers general vehicle infor-
mation
(010 General) as well as the recommended mainte-
nance schedules and service procedures to perform BMW
scheduled maintenance
work (020 Maintenance).
The next seven sections
(1 through 7) are repair based and
organized by three digit repair groups. Most major sections
begin with a GENERAL repair group,
e.g. 100 Engine-Gen-
eral. These "00 (double zero) groups contain descriptive the-
ory of operation and system troubleshooting information. The
remainder of the repair groups within a section contain the
service and repair information. The last two sections contain
detailed electrical wiring schematics and OBD
II scan tool and
diagnostic information.
Warnings, cautions and notes
Throughout this manual are many passages with the head-
ings WARNING, CAUTION, or NOTE. These very important
headings have different meanings.
WARNING-
The text under this heading warns of unsafe practices that
are very
likely to cause injury, either by direct threat to the per-
son(~) performing the work
orby increasedrisl( of accident or
mechanical failure while
drivinq.
CAUTION-
A CAUTION calls attention to importantprecautions to be ob-
senfed during the repair work that will help prevent acciden-
tally damaging the car or its parts.
NOTE-
A NOTE contains helpful information, tips that will help in do-
ing a betterjob and completing it more easily.
Please read every WARNING, CAUTION, AND NOTE in
001
General Warnings and Cautions and as they appear in re-
pair procedures. They are very important. Read them before
you begin any maintenance or repair job.

Maintenance
Service Interval lndicator (Sll)
The BMW Service Interval lndicator (SII) notifies the driver
when oil change and other service is required. The
Sll dis-
plays the phrase "OIL SERVICE"
or"INSPECTI0N" and 7
light emitting diodes (LEDs) in the Instrumentcluster: 5green,
one yellow and one red.
For the
1997 and later 5 Series, BMW introduced an oil
change interval based on fuel consumption. The advantages
of this system are:
Fuel consumption is an accurate method of determining
engine load and the need for service.
The processing electronics are simple.
Resetting of indicator before the scheduled time will not
affect the time to the next service.
4 The Sll is programmed to measure a set volume of con-
sumed fuel. This volume varies between models, dependent
on vehicle and engine size. The
Sil control unit receives a
signal from the engine control module (ECM) when the vehi-
cle is in use. As
20% of the programmed fuel volume is con-
sumed, one of the green LEDs will go out. Each successive
20% of fuel consumption will cause the next LED to go out
until
100% of the measured volume has been consumed. At
this point the yellow LED will come on, indicating that service
is due. When
108% of the measured volume has been con-
sumed, the red LED will illuminate, indicating that service is
overdue.
Service Interval Indicator (SII), resetting
After the specified maintenance has been carried out, the Sll
memory should be reset.
NOTE-
For reference, the BMW oil service requirements are approx-
imately equivalent to the maintenance tliat other European
manufacturers specify at intervals with a maximum of every
15.000 miles or I2 months.

Maintenance
Drive axle joint
(CV joint) boots, inspecting
CVjoint protective boots must be closely inspected forcracks
and any other damage that will allow contaminants to get into
the joint.
If the rubber boots fail, the water and dirt that enter
the joint will quickly damage it.
NOTE-
Replacement of the CVjoint boots and inspection of the
joints are described
in 331 Final Drive.
Exhaust system, inspecting
Exhaust system life varies widely according to driving habits
and environmental conditions. If short-distance driving pre-
dominates, the moisture and condensation in the system will
not fully dry out. This will lead to early corrosion damage and
more frequent replacement.
Scheduled maintenance of the exhaust system is limited to
inspection:
* Check to see that all the hangers (arrow) are in place and
properly supporting the system and that the system does
not strike the body.
Check for restrictions due to dents or
kinlts,
Check for weakness or perforation due to rust.
NOTE-
Alignment of the system and the location of the hangers are
described in
180 Exhaust System.
Fuel filter, replacing
The fuel filter is located beneath the center of the car, approx-
imately under the driver's seat.
A protective cover must be
removed to access the filter.
4 Fuel filter for M62 engine (arrow)
- Disconnect battery negative (-) cable
CAUTIOI\C
Disconnecting the battery cables may erase fault codes
stored
in engine control module memory.
WARNING -
Fuel will be expelled forcibly when the filter is removed. Do
notsmoke or work near heaters orother fire hazards. Keep a
fire extinguisher handy

OBD-6
On-Board Diagnostics
Fuel system monitoring. This monitor looks at the fuel
delivery needed (long
/short term fuel trim) for proper engine
operation based on programmed data. If too much or not
enough fuel is delivered over a predetermined time, a DTC is
set and the MIL illuminates.
Fuel trim refers to adiustments to base fuel schedule.
Lono- ., term fuel trim refers to gradual adjustments to the fuel
calibration adjustment as compared to short term fuel trim.
Long term fuel trim adjustments compensate for gradual
changes that occur over time.
Fuel system monitoring monitors the calculated injection time
(ti) in relation to enginespeed, load and precatalyticconverter
oxygen
sensor(s) signals.
Using this data, the system optimizes fuel delivery for all
engine operating conditions.
Evaporative system monitoring. This monitor checks the
the fuel storage system and related fuel lines for leaks. It can
detect very small leaks anywhere in the system.
A leak detection unit (LDP or DMTL) is used to pressurize the
evaporative control system on a continuous basis (as the
drive cycle allows) and to
check system integrity.
Drive cycle
The OED II drive cycle is an important concept in
understanding OBD
II requirements. The purpose of the drive
cycle is to run ail of the emission-related on-board diagnostics
over a broad range of driving conditions.
A drive cycle is considered complete when all of the
diagnostic monitors have run their tests without interruption.
~ora drive cycle to be initiated, the vehicle must be started
cold and brought up to
1 60°F and at least 40°F above its
original starting temperature.
Readiness codes
Inspection/maintenance (I/M) readiness codes are mandated
as part of OBD
II. The readiness code is stored aftercomplete
diagnostic monitoring of specified components and systems
is carried out. The readiness code function was designed to
prevent manipulating an
I/M emission test procedure by
clearing faults codes or disconnecting the ECM or battery.
