General
Torque wrench
A torque wrench is used to precisely tighten threaded fasten-
ers to a predetermined value. Many of the repair procedures
in this manual include BMW-specified torque values
in New-
ton-meters (Nm) and the equivalent values in foot-pounds
(ft-
Ib).
4 Several types of torque wrenches are available. An inexpen-
sive beam-type (top) is adequate but must be read visually. A
ratchet-type (bottom) can be preset to indicate (click) when
the torque value has been reached. They all do the same job,
but offer different convenience features at different prices.
The most convenient ones have a built-in ratchet, and can be
preset to indicate when a specific torque value has been
reached. Follow the wrench manufacturer's directions
for use
to achieve the greatest accuracy.
A torque wrench with a range up to about 150 Nm (1 10 ft-lb) BOIBFNG has adequate capacity for most of the repairs covered in this
manual. For recommended torque values of
10 Nm orbelow,
the English system equivalent is given in inch-pounds (in-lb).
These small values may be most easily reached using a
torque wrench calibrated in inch-pounds. To convert
inch-
pounds to foot-pounds, divide by 12.
Digital multimeter
4 Many of the electrical tests in this manual call for the mea-
surement of resistance (ohms) or voltage values. For safe
and accurate tests of sensitive electronic component and
systems, a multimeter or digital
volt/ohm meter (DVOM) with
high input impedance (at least
10,000Sr) should be used.
Some meters have automotive functions such as dwell and
pulse width that are useful for troubleshooting ignition and
fuel injection problems.
CAUTIOI\C
Vehicle electronic systems may be damaged by the high cur-
rent draw of a test light with a normal incandescent bulb. As
a general rule, use a high impedance digital multimeter or an
LED test light for all electrical testing.

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
1997 to 2000 models
1997 to 2000 models are equipped with a data link connector
(DLC) plug in the right side engine compartment:
Reset
SII using BMW service and scan tool (DISplus or MoD-
iC, GTI) or a specialty tool from another manufacturer. Plug
tool (arrow) into DLC.
CAUTION-
Follow the manufacturer's directions when resetting the Sll. If
the reset procedures are done
incorrect& the tool or the elec-
tronic Service Interval Indicator
may be damaged.
Aftermarket reset tools that can reset all models with the DLC
can be purchased from one of the following suppliers:

2001 and later models
On vehicles without the data link connector (DLC) in the en-
gine compartment (2001 and latercars), the reset tool can not
be used. Instead, the
Sll can be reset with the trip odometer
reset button in the instrument cluster.
Make sure ignition key is in OFF position.
* Press and hold trip odometer button in instrument cluster,
and turn ignition key to ACCESSORY position.
Keep
button pressed for approximately 5 seconds until
either of following appear in display: OIL SERVICE or
INSPECTION, with RESET.
Press button again and
hold for approximately 5 seconds
until RESET flashes.

Maintenance
0 Service due is shown with RESET if the measured con-
sumption limit has been reached and resetting is possible.
If RESET is not shown, the minimum limit has not been
reached and resetting is not possible.
While display is flashing, press button briefly to reset
Sll.
After display has shown new interval, the following will
appear in display for approximately
2 seconds: END SIA.
NOTE-
The system can only be reset again after the vehicle has
been driven approximately 50 to
75 miles (consumes at
least2.5gallons of fuel). If the display shows RESETwhen
resetting, the minimum driving distance has been fulfilled
and the system can be reset again.
0 It is possible to interrupt and end the reset procedure by
changing the position of the ignition
ley.
lnspection I, lnspection II
The Service Interval Indicator (SII) signals the need for main-
tenance and inspection. There are two sets
of inspection re-
quirements, alternating throughout a car's maintenance
history. If the last inspection interval was lnspection I, the next
inspection interval (following an oil service) will be lnspection
11, the next after that will be lnspection I, and so on.
lnspection
I tasks are listed in Table b. lnspection I Service.
lnspection
II includes most of the tasks from lnspection I with
additional lnspection
II tasks. A complete listing of lnspection
II tasks is in Table c. lnspection I1 Service.
NOTE-
For reference, the BMW lnspection I and lnspection I1 re-
quirements are approximately equivalent to the maintenance
requirements that other European manufacturers specify.
ln-
spection I is normally due at intervals with a maximum of
30,000 miles or
24 months. lnspection I1 is normally due at
intervals with a maximum of 60,000 miles or
48 months.

Maintenance
The intervals for most tasks listed in the maintenance tables
below are determined by the Sll.
NOTE-
BMW is constantly upgrading recommended maintenance
procedures and requirements.
The information contained
here is as accurate as possible at the time of publication. if
there is any doubt about what procedures apply to a specific
model or year, or what intervals should be followed, remem-
ber that an authorized
BMW dealer has the latest information
on factory-recommended maintenance.
Except where noted, the maintenance items listed apply to all
models and model years covered by this manual. The num-
ber in the "additional repair information" column refers to the

- Remove crankshaft locking tool from transmission bell hous-
ing so that crankshaft is no longer secured in
TDC position.
- Remove camshaft locking tools from cylinder head.
4 Turn engine over twice in direction of rotation until cylinder 1
intake and exhaust camshaft lobes (arrows) face each other.
- Secure crankshaft in TDC position with BMW special tool 11
2 300.
4 Place BMW special tool set 11 3 240 over camshafts and
measure clearances.
CAUTION-
- If the exhaust side of the tool (A) is not flush with tlie head,
camshaft timing is incorrect Reset camshaft timing as de-
scribed in
117 Camshaft Timing Chain.
* Due to flexible sprocket design, VANOS unit tolerances
and play in the VANOS splines, when the camshaft tim-
ing is set correctly, the intake side of special tool
11 3
240 (6) may be up to 1 mm (0.04 in.) above the surface
of the cylinder head. This is normal. Reassemble en-
gine.
Othe~lise, reset camshaft timing as described in
11 7 Camshaft Timing Chain.
- Remove BMW special tool 11 6 150 from front of cylinder
head.
