service BMW Z4 SDRIVE28I 2012 Service Manual

MaintenanceVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
BMW Maintenance System
The maintenance system provides information
on required maintenance measures and thus
provides support in maintaining road safety and
the operational reliability of the vehicle.
Condition Based Service CBS
Sensors and special algorithms take into ac‐
count the driving conditions of your vehicle.
Based on this, Condition Based Service deter‐
mines the maintenance requirements.
The system makes it possible to adapt the
amount of maintenance you need to your user
profile.
Details on the service requirements, refer to
page 65, can be displayed on the instrument
cluster.
Service data in the remote control
Information on the required maintenance is con‐
tinuously stored in the remote control. Your
service center will read out this data and suggest
the right array of service procedures for your ve‐
hicle.
Therefore, hand your service specialist the re‐
mote control that you used most recently.Storage periods
Storage periods during which the vehicle bat‐
tery was disconnected are not taken into ac‐
count.
If this occurs, have a service center update the
time-dependent maintenance procedures,
such as checking brake fluid and, if necessary,
changing the engine oil and the microfilter/acti‐
vated-charcoal filter.
Service and Warranty
Information Booklet for US
models and Warranty and
Service Guide Booklet for
Canadian models
Please consult your Service and Warranty Infor‐
mation Booklet for US models and Warranty and
Service Guide Booklet for Canadian models for
additional information on service requirements.
Maintenance and repair should be performed by
your service center. Make sure to have regular
maintenance procedures recorded in the vehi‐
cle's Service and Warranty Information Booklet
for US models, and in the Warranty and Service
Guide Booklet for Canadian models. These en‐
tries are proof of regular maintenance.Seite 168MobilityMaintenance168

Socket for OBD Onboard
Diagnosis
An OBD socket for testing components that are
critical to exhaust composition is located under
a cover on the driver's side.
Emissions
▷The warning lamp lights up:
The emissions values are deterio‐
rating. Have the vehicle checked as
soon as possible.▷The warning lamp flashes under certain cir‐
cumstances:
This indicates that there is excessive misfir‐
ing in the engine.
Reduce the vehicle speed and have the sys‐
tem checked immediately; otherwise, seri‐
ous engine misfiring within a brief period can
seriously damage emission control compo‐
nents, in particular the catalytic converter.
Display of the previously described mal‐
functions on Canadian models.
Fuel cap The indicator lamp lights up.
If the fuel cap is not properly tightened,
the OBD system may conclude that fuel vapor is
escaping. If the cap is then tightened, the display
should go out in a short time.
Data memory
Your vehicle records data relating to vehicle op‐
eration, faults and user settings. These data are
stored in the remote control and can be read out
with suitable devices, particularly when the ve‐
hicle is serviced. The data obtained in this way
provide valuable information for service proc‐
esses and repair or for optimizing and develop‐
ing vehicle functions further. In addition, if you
signed a service contract for Assist, certain ve‐
hicle data can be sent directly from the vehicle
to facilitate the desired services.Seite 169MaintenanceMobility169

Replacing componentsVehicle equipment
This chapter describes all series equipment as
well as country-specific and special equipment
offered for this model series.Therefore, it also
describes equipment that may not be found in
your vehicle, for instance due to the selected
special equipment or the country version. This
also applies to safety-related functions and sys‐
tems.
Tool kit
The onboard vehicle tool kit is stored in a pouch
under the trunk floor panel.
Replacing the wiper blades
1.Fold up the wiper arm.2.Fold the wiper blade upwards.3.Press the hook.4.Pull the wiper blade downward out of the
holder and remove it toward the top left, see
arrow.
Do not fold out the wiper arms
To avoid damage, make sure that the
wiper arms are resting against the windshield
before you open the engine compartment.◀
Lamp and bulb replacement
General information
Lamps and bulbs make an essential contribution
to vehicle safety.
The manufacturer of your vehicle recommends
that you entrust corresponding procedures to
your service center if you are unfamiliar with
them or they are not described here.
You can obtain a selection of replacement bulbs
at your service center.
Danger of burns
Only change bulbs when they are cool;
otherwise, there is the danger of getting
burned.◀
Working on the lighting system
When working on the lighting system, you
should always switch off the lights affected to
prevent short circuits.
To avoid possible injury or equipment damage
when replacing bulbs, observe any instructions
provided by the bulb manufacturer.◀
Do not touch the bulbs
Do not touch the glass of new bulbs with
your bare hands, as even minute amounts of
contamination will burn into the bulb's surface
and reduce its service life.

Use a clean tissue, cloth or something similar, or
hold the bulb by its base.◀
Light-emitting diodes LED
Light-emitting diodes installed behind translu‐
cent lenses serve as the light source for many of
the controls and displays in your vehicle.
These light-emitting diodes, which operate us‐
ing a concept similar to that applied in conven‐
tional lasers, are officially designated as Class 1
light-emitting diodes.
Do not remove the covers
Do not remove the covers, and never stare
into the unfiltered light for several hours; other‐
wise, irritation of the retina could result.◀
Headlamp glass
Condensation can form on the inside of the ex‐
ternal lamps in cool or humid weather. When you
drive with the lights switched on, the conden‐
sation evaporates after a short time. The head‐
lamp glasses do not need to be changed.
If the condensation in the headlamps does not
evaporate after trips with the lights switched on,
and the amount of moisture in the headlamps
increases, for example if water droplets form,
have them checked by your service center.
Xenon headlamps
Because of the long life of these bulbs, the like‐
lihood of failure is very low. Switching the lamps
on and off frequently shortens their life.
Do not perform work/bulb replacement on
xenon headlamps
Have any work on the xenon lighting system, in‐
cluding bulb replacement, performed only by a
service center.
Due to the high voltage present in the system,
there is the danger of fatal injuries if work is car‐
ried out improperly.◀Parking lamps, roadside parking lamps,
