2008 BMW Z4 COUPE spark plugs replace

Special Note
Maintenance items and schedules stated herein
reflect the combined recommendations for all
2008 BMW Z4 models and are subject to
change. The most current maintenance recom-
mendations 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.
Your BMW is factory-equipped with a newly-
developed synthetic engine oil. At the time of
the printing of this booklet BMW High-Perfor-
mance Synthetic 5W-30 Oil (Part Number
07 51 0 017 866) and Mobil 1 5W-30 and
5W-40 oils are strongly recommended and
approved by BMW for the BMW Z4 models.
BMW is evaluating various synthetic oils for
inclusion in our list of recommended motor
oils.
BMW recommends that you check engine oil
level whenever fuel is added to your vehicle.
 Inspection I: Major vehicle maintenance as
specified in the following pages under Inspec-
tion I.
 Inspection II: Additional major vehicle mainte-
nance 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
120,000 miles to maximize vehicle fuel econ-
omy and minimize exhaust pollution. The
replacement of the oxygen sensor is required
under the terms of the applicable BMW emis-
sion system warranties.
 Spark Plug Service: Replace spark plugs
every 100,000 miles.
 Automatic Transmission Service: Change ATF
every 100,000 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
operations to fulfill any state inspection require-
ments in your area concurrent with the mainte-
nance elements specified above during other
repairs. Should you request more frequent
maintenance service, the cost of these ser-
vices will not be covered by the Maintenance
Program.
Make sure that confirmation of maintenance
work is always entered in this Service and War-
ranty 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 technologi-
cal advances not only to the design and produc-
tion 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.
Your service technician looks forward to serving
your every service need and to help maximize
your satisfaction with your BMW, its longevity,
and resale value.

or inadequate maintenance, use of leaded fuel
or fuels containing more than 10% ethanol, or

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 WARRAN-
TIES, INCLUDING THE IMPLIED WARRANTY
OF MERCHANTABILITY, IS LIMITED TO THE
DURATION OF THE EXPRESS WARRANTIES
HEREIN.
BMW NA HEREBY EXCLUDES INCIDENTAL
AND CONSEQUENTIAL DAMAGES, INCLUD-
ING LOSS OF TIME, INCONVENIENCE, OR
LOSS OF USE OF THE VEHICLE, FOR ANY
BREACH OF ANY EXPRESS OR IMPLIED
WARRANTY, INCLUDING THE IMPLIED WAR-
RANTY 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 dam-
ages, so the above limitations and exclusions
may not apply to you. Additionally, if you are a
California, Connecticut, Maine, Massachusetts,
Rhode Island or Vermont resident and your vehi-
cle is registered in that state, your vehicle is eli-
gible 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.

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
an emergency 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 avail-
able 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, parts and diagnosis not to exceed BMW
suggested retail price for all warranted parts
replaced and labor charges based on the manu-
facturer’s recommended time allowance for the
warranty repair and the geographically appropri-
ate hourly labor rate) that are covered under this
warranty. Replaced parts and paid invoices must
be presented to a BMW center as a condition of
reimbursement for emergency repairs not per-
formed by a BMW center.
The use of replacement parts, which are not of
equivalent quality, may impair the effectiveness
of emission control systems. If other than genu-
ine 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 assur-
ances that such 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-genuine BMW replace-
ment parts does not invalidate the warranty on
other components, unless non-genuine 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, dis-
connection, improper or inadequate mainte-
nance, 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 sal-
vage purposes.
