spark plugs replace BMW M3 2004 E46 Service and warranty information

3 The performance of certain subsequent
maintenance 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 changed with the
engine at operating temperature. Note:
change oil at least once a year. Your BMW is
factory-equipped with a newly-developed
synthetic engine oil. At the time of the
printing of this booklet the only approved
engine oils are:
Castrol TWS Motorsport SAE 10W-60
Synthetic, or Castrol Formula RS 10W-60
Synthetic (BMW part number 07 51 0 009
420). BMW is evaluating various synthetic
oils for inclusion in our list of recommended
motor oils.
For the most current list of synthetic oils,
please contact your BMW center, or call
BMW of North America at 1-800-831-1117.
You can also obtain this information from
our website, www.bmwusa.com/.
It is recommended to check engine oil level
whenever fuel is added to the 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 SJ or
higher.
– Inspection I: Major vehicle maintenance
as specified in the following pages under
Inspection I.
– Inspection II: Additional major vehicle
maintenance as specified in the following
pages under Inspection II.
The following maintenance elements must
be performed at the mileage/time stated
(time intervals begin from the vehicle’s
production date):
– Brake Fluid Service: Change brake fluid
every two years.– Oxygen Sensor Service: The oxygen sensor
deteriorates strictly on a mileage basis and
must therefore be replaced every 100,000
miles to maximize vehicle fuel economy
and minimize exhaust pollution. The
replacement of the oxygen sensor is
required under the terms of the appli-
cable BMW emission system warranties.
– Spark Plug Service: Replace spark plugs
every Inspection II). Your BMW is equipped
with platinum-tipped spark plugs. These
allow a longer service life than conven-
tional spark plugs.
The engine coolant has a lifetime rating and
does not need to be changed.
For your convenience, you may also wish to
have your BMW center perform any necessary
operations to fulfill any state inspection
requirements in your area concurrent with the
maintenance elements specified above during
other repairs.
Make sure that confirmation of maintenance
work is always entered in this Service and
Warranty Information Statement. You may need
this for any warranty claims that become
necessary, and later on as evidence that your
car has been given the correct and regular
maintenance that justifies its resale or trade-in
value.
BMW has applied the most modern techno-
logical advances not only to the design and
production of your vehicle, but also to
computing of the optimum maintenance
interval for your type of operations and
driving style. Your BMW center has made a
substantial investment in unique BMW
special service tools to enable his BMW
factory trained service technicians to perform
quality repairs on your BMW in minimal time.
He/she looks forward to serving your every
service need and to help maximize your
satisfaction with your BMW, its longevity, and
resale value.

New Vehicle Limited Warranty -
2004 M3 (Valid only in the U.S.A.
and Puerto Rico)

31 parts are warranted by their manufacturer 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-BMW replacement
parts or non-EPA certified parts does not
invalidate the warranty on other compo-
nents, unless non-BMW parts or non-EPA
certified parts cause damage to warranted
parts.
What is not covered
This warranty does not cover malfunctions
caused by any of the following: accident,
flood, misuse, improper adjustment, modifi-
cation, alteration, tampering, disconnection,
improper or inadequate maintenance, use of
leaded fuel or fuels containing more than
10% ethanol, or other oxygenates with more
than 2.8% oxygen by weight (i.e., more than
15% MTBE or more than 3% methanol plus
an equivalent amount of co-solvent).
The replacement of maintenance parts, such
as spark plugs, filters and similar items used
in required maintenance services, the repair
or replacement of maintenance parts
beyond the first required inspection/mainte-
nance, or if the part has been replaced
earlier for reasons other than it being
defective.
The car or any part of the car unless a failure
causes the car to fail to conform to appli-
cable emission regulations.
Any car on which the odometer has been
replaced or altered and the true mileage
cannot be determined.
The car, if the vehicle identification number
is altered or cannot be read, or if the car has
been declared a total loss or sold for
salvage purposes.General
These warranties give you specific legal
rights, and you may also have other rights
which vary from state to state.
THE DURATION OF ANY IMPLIED WAR-
RANTIES, INCLUDING THE IMPLIED
WARRANTY OF MERCHANTABILITY, IS
LIMITED TO THE DURATION OF THE
EXPRESS WARRANTIES HEREIN.
BMW NA HEREBY EXCLUDES INCIDEN-
TAL AND CONSEQUENTIAL DAMAGES,
INCLUDING LOSS OF TIME, INCONVE-
NIENCE, OR LOSS OF USE OF THE
VEHICLE, FOR ANY BREACH OF ANY
EXPRESS OR IMPLIED WARRANTY,
INCLUDING THE IMPLIED WARRANTY OF
MERCHANTABILITY, APPLICABLE TO THIS
PRODUCT.
Some states do not allow limitations on how
long an implied warranty lasts, or the
exclusion or limitation of incidental or
consequential damages, so the above
limitations and exclusions may not apply to
you. Additionally, if you are a California,
Massachusetts, Vermont or Maine resident
and your vehicle is registered in that state,
your vehicle is eligible for California
Emissions Warranty coverage.
These federal warranty provisions also
apply to all vehicles sold in all U.S. states
and territories regardless of whether a state
has enacted state warranty provisions that
differ from the federal provisions.

36 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
demonstrates that such lack of required
maintenance is a direct cause of the emission
control system failure. The instructions for
required maintenance and use can be found in
the Owner’s Manual and in the Service section
of this Statement.
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 Autho-
rized Remanufactured Parts. Without invalidat-
ing this warranty, the owner may elect to have
maintenance, 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 genuine BMW Service
Par ts. However, the cost of such service or
parts will not be covered under this warranty,
except in emergency situations. In an emer-
gency situation, where an authorized BMW
center is not reasonably available or a
warranty replacement part is not available
within 30 days, repairs may be performed at
any available service establishment or by any
individual using any replacement part.
A repair not completed within 30 days consti-
tutes an emergency. BMW NA will reimburse
the owner for such emergency repairs
(including labor, par ts and diagnosis not to
exceed BMW suggested retail price for all
warranted parts replaced and labor charges
based on the manufacturer’s recommended
time allowance for the warranty repair and the
geographically appropriate hourly labor rate)
that are covered under this warranty. Re-
placed parts and paid invoices must be
presented to a BMW center as a condition of
reimbursement for emergency repairs not
performed by a BMW center.
The use of replacement parts, which are not of
equivalent quality, may impair the effective-
ness of emission control systems. If other than
genuine BMW Service Parts or Authorized
Remanu-factured Parts are used for mainte-nance, repair or replacement of components
affecting emission control, the owner should
obtain assurances that such parts are war-
ranted by their manufacturer 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-BMW replacement
parts does not invalidate the warranty on other
components, unless non-BMW parts cause
damage to warranted parts.
What is not covered
This warranty does not cover malfunctions
caused by any of the following: accident, flood,
misuse, modification, alteration, tampering,
disconnection, improper or inadequate
maintenance, except if performed by an
authorized BMW center doing warranty repair
work, use of leaded fuel or fuel other than as
specified in the Owner’s Manual.
The replacement of maintenance parts, such
as spark plugs, filters and similar items used in
required maintenance services or the repair or
replacement of maintenance parts beyond the
first replacement interval.
Any car on which the odometer has been
replaced or altered and the true mileage
cannot be determined.
The car, if the vehicle identification number is
altered or cannot be determined, or if the car
has been declared a total loss or sold for
salvage purposes.
General
The warranty gives you specific legal rights,
and you may also have other rights which vary
from state to state.
THE DURATION OF ANY IMPLIED WARRAN-
TIES, INCLUDING THE IMPLIED WARRANTY
OF MERCHANTABILITY, IS LIMITED TO THE
DURATION OF THE EXPRESS WARRANTIES
HEREIN. BMW OF NORTH AMERICA
