2008 BMW X3 sensor

The performance of certain subsequent mainte-
nance elements, as required by the BMW New
SAV Limited Warranty, will be specified at inter-
vals 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 BMW X3s are factory-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 5W-30
 Mobil 1 5W-40
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 authorized BMW SAV center, or call
BMW of North America, LLC at
1 800 831-1117. You can also obtain this infor-
mation 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
SJ or higher.
 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: The X3 is equipped with
platinum-tipped spark plugs. These allow a
longer service life than conventional plugs.
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.
Please see your authorized BMW SAV center for
the most current information.
For your convenience, you may also wish to
have your authorized BMW SAV center perform
any necessary operations to fulfill any state
inspection requirements in your area concurrent
with the maintenance elements specified above
during other repairs. Should you request more
frequent maintenance service, the cost of
these services will not be covered by the
Maintenance Program.
Make sure that confirmation of maintenance
work is always entered in this SAV Service and
Warranty Information Booklet. You may need this
for any warranty claims that become necessary,
and later on as evidence that your SAV 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 SAV, but also to computing of the
optimum maintenance interval for your type of
operations and driving style. Your authorized
BMW SAV center has made a substantial invest-
ment in unique BMW special service tools to
enable BMW factory trained service technicians
to perform quality repairs on your BMW in mini-
mal 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.
