2008 BMW 3 SERIES service indicator

speeds during acceleration requires more fre-
quent maintenance intervals than a vehicle
driven for 50,000 miles for long distances at low
engine speeds primarily at operating
temperature.
The advanced technologies at BMW have led to
the development of the unique BMW Condition
Based Service (CBS) system which computes
the actual optimum maintenance requirements
based not only upon the accumulated mileage,
but taking into account important factors such
as high or low engine speeds, short or long trip
driving, and condition of the engine oil and
brake pads.
Condition Based Service (CBS)
CBS is a further development of the Service
Interval Indicator System. Sensors and sophisti-
cated algorithms take even more detailed
account of the various conditions of vehicle use.
The remaining times for selected maintenance
tasks as well as any legally prescribed dates are
displayed to you individually:
 Engine oil
 Brakes - front and rear separately
 Brake fluid
 Vehicle check
 Required State Inspection(s)
CBS thus determines the current and future
maintenance requirements. This data can also
be read from the vehicle key by your BMW Ser-
vice Advisor and used to propose the optimum
scope of maintenance.
Disconnecting the battery during periods
of long-term storage will interrupt the
calculation of time-based services. Have all
items requiring time-based maintenance, such
as brake fluid and possibly also the engine oil
and microfilter, brought up to date by your BMW
center. Also see the section on battery care on
page 17 of this statement.

Advisor at your BMW center has a device called
a key reader. When your Service Advisor inserts
your key into the key reader, all pertinent vehicle
and servicing data will be available, and a cus-
tomized maintenance checklist is printed out
based on the specific operations called for by
the Condition Based Service.
Special Note
The maintenance requirements for your vehicle
are determined dynamically by the Condition
Based Service (CBS) system. The maintenance
items stated herein reflect the latest information
available at the time of the printing of this state-
ment, and are subject to change. The most cur-
rent maintenance recommendations are
available from your authorized BMW center. The performance of certain subsequent mainte-
nance elements, as required by the BMW New
Vehicle Limited Warranty, will be specified at
intervals computed by the BMW Service Interval
Indicator as follows:

Oil Service: Engine oil should be changed
with the engine at operating temperature.
Note: Change oil at least once a year.
All 2008 model year 3 Series vehicles are facto-
ry-filled with BMW High Performance Synthetic
oils. At the time of the printing of this booklet,
the following oils are strongly recommended
and approved by BMW:
 BMW High Performance 5W-30 Synthetic Oil
(BMW part number 07 51 0 017 866)
 Mobil 1 10W-40 Synthetic
BMW is evaluating various synthetic oils for
inclusion in our list of recommended engine oils.
For the most current list of synthetic oils, please
contact your BMW center, or call BMW of North
America, LLC at 1 800 831-1117. You can also
obtain this information from our website,
www.bmwusa.com/.
BMW recommends that you check your engine
oil level whenever you add fuel to your vehicle. If
you need to add oil between oil changes and
are unable to obtain BMW High Performance
Synthetic Oil, Mobil 1 or another special oil on
the list, use a synthetic oil with an API rating of
SH or higher.
The following maintenance elements must be
performed at the mileage/time stated (time inter-
vals begin from the vehicles production date):
 Brake Fluid Service: Change brake fluid every
two years, or when specified by CBS.
 Oxygen Sensor Service: The oxygen sensor
deteriorates strictly on a mileage basis and
must therefore be replaced every
120,000 miles to maximize vehicle fuel econ-
omy and minimize exhaust pollution. For the
328i SULEV (PZEV) models, the oxygen sen-
sor must be replaced every 150,000 miles.
The replacement of the oxygen sensor is
required under the terms of the applicable
BMW emission system warranties.
 Spark Plug Service (not shown in CBS).
Replace at the following intervals:
328i versions: 100,000 miles
335i versions: 45,000 miles

The engine coolant has a lifetime rating and
does not need to be changed except for sys-
tem repairs.
For your convenience, you may also wish to have
your BMW center perform any necessary opera-
tions to fulfill any state inspection requirements in
your area concurrent with the maintenance ele-
ments specified above during other repairs.
Should you request more frequent mainte-
nance service, the cost of these services will
not be covered by the Maintenance Program.
BMW has applied the most modern technological
advances not only to the design and production of
your vehicle, but also to computing of the opti-
mum maintenance interval for your type of opera-
tions and driving style. Your BMW center has
made a substantial investment in unique BMW
special service tools to enable BMW factory
trained service technicians to perform quality
repairs on your BMW in minimal time. Your service
technician looks forward to serving your every ser-
vice need and to help maximize your satisfaction
with your BMW, its longevity, and resale value.

Federal Emissions System Defect
Warranty (Valid only in the U.S.A.
and Puerto Rico)
This warranty applies only to U.S. specification
vehicles distributed by BMW of North America,
LLC (BMW NA) or sold through the BMW NA
European Delivery Program.
In accordance with the defect warranty provi-
sions of section 207(b) of the Clean Air Act,
BMW NA warrants to the first retail purchaser,
and each subsequent purchaser, that the car (a)
was designed, built and equipped so as to con-
form, at the time of sale, with all regulations of
the U.S. Environmental Protection Agency appli-
cable at the time of manufacture and (b) is free
from defects in materials and workmanship
which would cause it to fail to conform with
applicable regulations for a period of 2 years or
24,000 miles, whichever occurs first, except for
specific emission control components (as listed
on page 38), for which the warranty period is
8 years or 80,000 miles, whichever occurs first.
Coverage begins on the date of first retail sale
or the date the vehicle is first placed into service
as a sales demonstrator, service loaner (SLP) or
company vehicle, whichever is earlier.
Warranty claims must be made as soon as rea-
sonably possible after a defect is discovered. To
make a claim, the car must be brought to any
authorized BMW center during normal business
hours.
The BMW center will, without charge for parts
or labor (including diagnosis), either repair or
replace the defective part, if any. The decision
whether to repair or replace said parts is solely
the prerogative of BMW NA and must be
expected to correct the failure of the warranted
part. Parts for which replacements are made
become the property of BMW NA. In all cases, a
reasonable time must be allowed for warranty
repairs to be completed after the car is received
by the BMW center.
For assistance in determining which specific
parts or components of your vehicle are covered
under this warranty, please contact your BMW
center. It is the owners responsibility to have all sched-
uled inspection and maintenance services per-
formed (at the owners expense), as prescribed
in the maintenance schedule for the BMW Emis-
sion Control System. Service intervals are com-
puted by the onboard BMW service interval
indicator and displayed on the instrument panel.
The instructions for proper maintenance and
use can be found in the Owners Manual. It is
strongly recommended that any replacement
parts used for maintenance, repair or replace-
ment of emission control systems be certified
BMW Service Parts or BMW Authorized
Remanufactured Parts. Without invalidating this
warranty, the owner may elect to have mainte-
nance, repair or replacement of the emission
control systems performed by any automotive
repair establishment, or elect to use parts other
than certified BMW Service Parts. However, the
cost of such service or parts will not be covered
under this warranty, except in emergency situa-
tions. In an emergency situation, where an
authorized BMW center or a warranty replace-
ment part is not reasonably available (within
30 days), repairs may be performed at any avail-
able service establishment using any equivalent
part. BMW NA will reimburse the owner for such
emergency repairs (including labor, parts and
diagnosis not to exceed BMW NA rates for labor,
parts, and diagnosis in said area) that are cov-
ered under this warranty. Replaced parts and
paid invoices must be presented at a BMW cen-
ter as a condition of reimbursement for emer-
gency repairs not performed by a BMW center.
The use of replacement parts, which are not of
equivalent quality, may impair the effectiveness
of the emission control system. If other than cer-
tified BMW Service Parts or Authorized Remanu-
factured Parts are used for maintenance, repair
or replacement of components affecting emis-
sion control, the owner should obtain assurances
that such parts are warranted by their manufac-
turer to be equivalent to genuine BMW parts in
performance and durability. BMW NA assumes
no liability under this warranty with respect to
parts other than genuine BMW parts.
However, the use of non-genuine BMW replace-
ment parts or non-EPA certified parts does not
invalidate the warranty on other components,
unless non-genuine BMW parts or non-EPA cer-
tified parts cause damage to warranted parts.

California Emission Control
System Limited Warranty SULEV
(PZEV)*
This warranty applies to California certified vehi-
cles distributed by BMW of North America
(BMW NA) or sold through the BMW NA Euro-
pean Delivery Program, registered and operated
primarily in California.
BMW NA warrants to the original purchaser and
each subsequent owner that the vehicle is:
a. designed, built and equipped so as to con- form with the applicable California Air
Resources Board emission standards.
b. free from defects in materials and workman- ship which cause any part that can affect
emissions to fail to conform with applicable
requirements or to fail a California Smog
Check test or EPA approved short test for a
period of 15 years or 150,000, whichever
occurs first.
c. free from defects in materials and workman- ship in emission related parts for a period of
15 years or 150,000, whichever occurs first.
Coverage begins on the date of first retail sale
or the date the vehicle is first placed into service
as a sales demonstrator, service loaner (SLP) or
company vehicle, whichever is earlier.
To obtain service under this warranty, the vehi-
cle must be brought, upon failure of a Smog
Check test or upon discovery of the defect, to
the workshop of any authorized BMW center,
during normal business hours. The BMW center
will honor or deny your claim within 30 days. If
the claim is denied, the BMW center will notify
you in writing of the reason(s). The BMW center
is required by law to honor the claim if notice is
not given to the owner within 30 days.
The BMW center will, without charge for parts
or labor (including diagnosis), either adjust,
repair or replace the defective part and other
parts affected by the failure of the warranted
part, if any. If your vehicle failed the California
Smog Check test or an EPA approved short test,
then BMW NA will repair your vehicle so that it
will pass this test. Items that require scheduled replacement are warranted up to the replace-
ment interval specified in the Service section of
this Statement. BMW NA may repair a part in
lieu of replacing it when performing warranty
repairs. Parts for which replacements are made
become the property of BMW NA.
A repair performed as the result of a smog
check test failure due to a defect in a part, which
is warranted for 15 years/150,000, is covered.
In all cases, a reasonable time, not to exceed
30 days, must be allowed for a warranty repair to
be completed, after the car is received by the
BMW center.
It is the owners responsibility to have all
required maintenance services performed (at
the owners expense), as prescribed in the main-
tenance schedule for the BMW Emission Con-
trol System. Service intervals are computed by
the service interval indicator and displayed on
the instrument panel.
However, BMW NA will not deny your warranty
repair claims solely because you do not have
maintenance records or you did not perform the
required maintenance unless BMW NA demon-
strates that such lack of required maintenance is
a direct cause of the emission control system
failure. The instructions for required mainte-
nance and use can be found in the Owner’s
Manual and in the Service section of this
Statement.
*The California Emissions Control System Lim-
ited Warranty SULEV (PZEV) applies to all 2008
U.S. specification BMW SULEV (PZEV) vehicles
sold, leased, and/or registered in California,
Connecticut, Maine, Massachusetts, New Jer-
sey, New York, Rhode Island or Vermont.
It is strongly recommended that any replace-
ment parts used for maintenance, repair or
replacement of emission control systems be
genuine BMW Service Parts or BMW Authorized
Remanufactured Parts. Without invalidating this
warranty, the owner may elect to have mainte-
nance, repair or replacement of the emission
control systems performed by any automotive
repair establishment, or elect to use parts other
than BMW Authorized Remanufactured or genu-
ine BMW Service Parts. However, the cost of
such service or parts will not be covered under
this warranty, except in emergency situations. In
