2004 BMW M3 Service and warranty information

Federal Emissions System
Defect Warranty
(Valid only in the U.S.A. and
Puerto Rico)
30 This warranty applies only to U.S. specifica-
tion vehicles distributed by BMW of North
America (BMW NA) or sold through the BMW
NA European Delivery Program.
In accordance with the defect warranty
provisions 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 conform, at the time of
sale, with all regulations of the U.S. Environ-
mental Protection Agency applicable 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 compo-
nents (as listed on page 33), for which the
warranty period is 8 years or 80,000 miles,
whichever occurs first.
This warranty begins on the date of first
retail sale, or the date the vehicle is first
placed in service as a demonstrator or
company vehicle, whichever is earlier.
Warranty claims must be made as soon as
reasonably 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 reason-
able 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 owner’s responsibility to have all
scheduled inspection and maintenance
services performed (at the owner’s ex-
pense), as prescribed in the maintenance
schedule for the BMW Emission Control
System. Service intervals are computed 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 Owner’s Manual. It is
strongly recommended that any replacement
parts used for maintenance, repair or
replacement of emission control systems be
certified BMW Service Parts or BMW
Authorized Remanufactured Parts. Without
invalidating this warranty, the owner may
elect to have maintenance, repair or
replacement of the emission control systems
performed by any automotive repair estab-
lishment, 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 situations. In an emergency
situation, where an authorized BMW center
or a warranty replacement part is not
reasonably available (within 30 days),
repairs may be performed at any available
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 covered under this warranty.
Replaced parts and paid invoices must be
presented at 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 effec-
tiveness of the emission control system. If
other than certified BMW Service Parts or
Authorized Remanufactured Parts are used
for maintenance, repair or replacement of
components affecting emission control, the
owner should obtain assurances that such

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.

In those states and jurisdictions that have
established periodic vehicle emissions tests to
encourage proper vehicle maintenance and
require the car to pass an emissions test
approved by the U.S. Environmental Protection
Agency and:
1. The car was distributed by BMW of North
America (BMW NA), or sold through the
BMW NA European Delivery Program; and
2. The car has been maintained and oper-
ated in accordance with the instructions for
proper maintenance and use set forth in
the Owner’s Manual supplied with the car;
and
3. The car fails to conform to the applicable
emissions standards of the EPA as judged
by an EPA approved emissions test; and
4. The failure to conform results or will result
in the owner of the car having to bear a
penalty or other sanction (including the
denial of the right to use the car) under
local state or federal law if the non-
conformity is not remedied within a
specified period of time.
Then, in accordance with the provisions of
section 207(b) of the Clean Air Act, BMW NA
warrants that if the car is eligible for coverage
under this warranty, any non-conformities in
the car, which cause it to fail an EPA-approved
emissions test will, without charge for parts or
labor (including diagnosis), be adjusted,
repaired, or replaced, at the option of BMW NA
to proper specifications, in order to make the
car comply with applicable emissions stan-
dards. The decision to adjust, repair or replace
parts is solely the prerogative of BMW NA and
must reasonably be expected to correct the
failure of the warranted part.This warranty begins on the date of first retail
sale, or the date the vehicle is first placed in
service as a demonstrator or company vehicle,
whichever is earlier. This warranty continues
for a period of 2 years or 24,000 miles,
whichever occurs first, except for specific
emissions control components (as listed on
page 33), for which the warranty period is 8
years or 80,000 miles whichever occurs first.
This warranty is made subject to the terms and
conditions that apply to the Emission Control
System Warranty and the New Vehicle Limited
Warranty.
No claim under this warranty will be denied
on the basis of use of a properly installed
EPA certified emission part for maintenance
and repair.
A vehicle manufacturer may deny an emission
performance warranty claim on the basis of an
uncertified replacement part used in the
maintenance or repair of a vehicle only if the
vehicle manufacturer presents evidence that
the uncertified replacement part is either
defective in materials or workmanship or not
equivalent from an emission standpoint to the
original equipment part.
Maintenance, replacement, or repair of
emission control devices and systems may
be performed by any automotive repair
establishment or individual using any
certified part.
Immediately after the car has failed an EPA
approved emission short test, your claim can
be made at any authorized BMW center. The
BMW center will honor or deny your claim
within the time period specified by local or
state laws (not to exceed 30 days), to avoid
further penalties or sanctions. lf 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 of
denial is not received by the owner within the
specified time period.

the emission warranties, or report violations of

The California Air Resources Board and BMW
of North America (BMW NA) are pleased to
explain the emission control system warranty
on your 2004 vehicle. In California, new motor
vehicles must be designed, built and equipped
to meet the State’s stringent anti-smog
standards. BMW NA must warrant the
emission control system on your vehicle for the
periods of time listed below provided there has
been no abuse, neglect or improper mainte-
nance of your vehicle.
Your emission control system may include
parts such as the fuel injection system, the
ignition system, catalytic converter, and engine
computer. Also included may be hoses, belts,
connectors and other emission-related
assemblies.
Where a warrantable condition exists, BMW
NA will repair your vehicle at no cost to you
including diagnosis, parts and labor.
Manufacturer’s Warranty Coverage:
– For 3 years or 50,000 miles whichever
occurs first:
1. If your vehicle fails a Smog Check inspec-
tion, all necessary repairs and adjustments
will be made by BMW NA to ensure that
your vehicle passes the inspection. This is
your emission control system PERFOR-
MANCE WARRANTY.
2. If any emission-related part on your vehicle
is defective, the part will be repaired or
replaced by BMW NA. This is your short-
term emission control system DEFECTS
WARRANTY.
– For 7 years or 70,000 miles whichever
occurs first:
If an emission-related part, specially noted on
page 40 as having coverage for 7 years or70,000 miles is defective, the part will be
repaired or replaced by BMW NA. This is your
long-term emission control system DEFECTS
WARRANTY.
Owner’s Warranty Responsibilities:
– As the vehicle owner, you are responsible
for the performance of the required
maintenance listed in your Owner’s
Manual. BMW NA recommends that you
retain all receipts covering maintenance on
your vehicle, but BMW NA cannot deny
warranty solely for the lack of receipts or for
your failure to ensure the performance of all
scheduled maintenance.
– You are responsible for presenting your
vehicle to an authorized BMW center as
soon as a problem exists. The warranty
repairs should be completed in a reason-
able amount of time, not to exceed 30 days.
– As the vehicle owner, you should also be
aware that BMW NA may deny your
warranty coverage if your vehicle or part
has failed due to abuse, neglect, improper
maintenance or unapproved modifications.

California Emission Control
System Limited Warranty*
This warranty applies to California certified
vehicles distributed by BMW of North America
(BMW NA) or sold through the BMW NA
European 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
conform 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 3 years or 50,000 miles, which-
ever occurs first.
(c) free from defects in materials and workman-
ship in emission related parts, which are
contained in the California Emission
Warranty Parts List on page 40, for a period
of 7 years or 70,000 miles, whichever
occurs first.
This warranty begins on the date of first retail
sale, or the date the vehicle is first placed in
service as a demonstrator or company vehicle,
whichever is earlier.
To obtain service under this warranty, the
vehicle 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 replacement 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. After 3 years or 50,000 miles, and
in accordance with paragraph (c) above, such
repairs are limited to the repair or replacement
of those parts identified in the California
Emissions Warranty List.
If your California registered vehicle is between
7 and 8 years old and has been driven less
than 80,000 miles, then your vehicle is eligible
for additional warranty coverage under the
Federal Emissions Warranty.
A repair performed as the result of a smog
check test failure due to a defect in a part,
which is warranted for 7 years/70,000 miles, 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 owner’s responsibility to have all
required maintenance services performed (at
the owner’s expense), as prescribed in the
maintenance schedule for the BMW Emission
Control System. Service intervals are com-
puted by the service interval indicator and
displayed on the instrument panel.
*The California Emissions Control System
Limited Warranty applies to all 2004 U.S.
specification BMW vehicles sold, leased, and/
or registered in California, Maine, Massachu-
setts or Vermont.

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.
