saved in the vehicle’s ignition key. The Service
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.
