17Service and M aintenance

Objectives

After com pleting this m odule you should be able to:

Identify the checklist needed to properly com plete any m aintenance service.

D em onstrate the proper procedures in com pleting a Q C I, O il Service and Inspection Ior II Service.

U nderstand the B M W B attery M aintenance System for in-stock vehicles.

D em onstrate the ability to program C ar and K ey M em ory features.

Recognize various m aintenance item s that are perform ed on a tim e/m ileage basis.


3/33


Introduction

The purpose of this m odule is to expose new B M W Technicians to Service M aintenance

Schedules and procedures unique to B M W .

R egular scheduled services and m aintenance w hen perform ed properly help to avoid

unexpected break dow ns and repairs and reduce the cost of ow nership.

Since M odel Year 2000 all B M W vehicles are covered by a standard Full M aintenance

program of 36 m onths and 36,000 m iles (750iL standard plan is 4 years/50,000 miles). Full

m aintenance program s include all factory recom m ended services as listed in the B M W

Service and W arranty booklet, plus replacem ent of w ear item s such as brake linings, brake

rotors, belts and w iper inserts. These program s are a benefit designed to cover all

scheduled m aintenance or additional required m aintenance costs.

Tim e intervals should be follow ed using the m aintenance interval as indicated by the B M W

Service Indicator System .

B M W s Scheduled Services are:

Q uality C ertification I (part I and II)

1200 m ile Service (som e m odels)

O il Service

Inspection I

Inspection II

Service requirem ents change frequently, therefore it is im portant that the correct checklists

are used w hen perform ing all services, this prevents oversight of steps that need to be

perform ed for each different service.

Service M aintenance C hecklists are sent autom atic shipm ent for each m odel year. To order

additional checklists use the Service Engineering M aterials O rdering form s. The itemnum bers are published in S .I. 00 24 89.


4/33


Quality Certification I

Every new vehicle w hich arrives at the B M W center requires that a Q uality C ertification (Q C I)

be perform ed. The Q C Iis perform ed in tw o parts.

D isplay Vehicle C heck

D elivery C heck

Display Vehicle CheckThe D isplay Vehicle C heck is perform ed if the vehicle is to be stored on the centers lot or

in the show room . The vehicle is inspected for shipping dam age and any defects that m ay

not have been caught at the VPC (Vehicle P reparation C enter).

C om plete the upper portion of the checklist and the box labeled 00 00 008 D isplay

Vehicle C heck-Technician.

Rem ove the top copy of the checklist and attach it to the repair order.

The rem aining portion of the checklist should be left in the vehicle or put into the vehicle

sales file.

Delivery CheckThe D elivery C heck is perform ed no m ore than 24 hours prior to the custom er taking

delivery of the vehicle. The purpose of the display check is to ensure that no dam age or

system problem s have appeared since the vehicle w as first checked at arrival to the

center. The B M W center m ust deliver a vehicle to the custom er free of any defects at tim eof delivery, this is difficult to ensure if the vehicle has not been inspected for several days or

w eeks.

Vehicles that are sold before arrival to the center or to be put into service as Loaner C ars

m ay have both parts of the Q C Iperform ed together, this is referred to as a Spot D elivery.

In this case the vehicle w ill not be sitting on the lot m ore than 24 hours before delivery.

Alw ays refer to the latest Service Inform ation for special instructions and w arranty

inform ation that is necessary to properly perform a Q C I.

Workshop Hints

Battery Disconnect SwitchesAll B M W s arrive at the center equipped w ith a battery disconnect sw itch. The purpose of

the sw itch is to allow an easy w ay to disconnect the battery circuit w hen the vehicle is notin use. D isconnecting the battery allow s service intervals to be extended to 3 m onths on

vehicles w hich are in storage.

There are tw o types of B attery D isconnect sw itches:

M echanical

Electronic

Mechanical Battery Disconnect SwitchThe m echanical sw itch is connected to the

negative ground point of the battery and

com e in various lengths.

At the end of the sw itch is a large red plastic

key that is used to interrupt the battery

ground circuit.

The battery disconnect sw itch should only be

left in if the vehicle is to be placed into

storage. After the vehicle is parked the sw itch

can be turned off.

U nder no circum stances should the vehicle be delivered to a custom er w ith the battery

sw itch still installed, it should be rem oved during the second half of the Q C I.

If the vehicle is to be used as a dem o. or put into Loaner C ar service, the B attery

D isconnect sw itch should be rem oved during the initial check.

W hen the sw itch is rem oved from the vehicle it should be returned to the Parts D epartm ent

w here it can be shipped back to B M W to be recycled in another vehicle.

Electronic Battery Disconnect Switch (EBS)

Since 2000 a new battery disconnect sw itch has begun to replace the m echanical type.The purpose of the sw itch rem ains the sam e as the m echanical type, so does the criteria

for rem oving it or leaving it installed.

The EB S kit includes:

M agnetic pen w ith holder

M agnetic sensor w ith cable

Electronic B attery cable

The m agnetic pen is used to turn the sw itch

on and off. It is usually attached to the low er

left corner of the w indshield (Fig.1).

The m agnetic sensor w ith connecting cable

is installed inside the vehicle and attached to

the drivers sun visor bracket m ounting points

(1). The connecting cable plugs into a

connector for the signal line w hich is routed

to the battery area. The signal line w iring is a

perm anent part of the vehicle w iring and is

not rem oved (Fig. 2).

To connect or disconnect the battery hold

the m agnetic pen in front of the sensor. The

sw itch includes a status LED and O n and O ff

m arkings.

W hen the pen is held in front of the O ffsensor the LED w ill turn off. The battery is

now disconnected.

Status of the sw itch is as easy as view ing

w hether the LED is on or off from outside of

the vehicle (Fig 3).

In order to rem ove the Electronic B attery D isconnect Sw itch from the vehicle:

1. D isconnect the negative term inal of the

battery.2. D isconnect the tw o nuts from the bolt

connections (2)on the BST and rem ove

the electronic disconnect sw itch.

3. D isconnect the 3-pin plug

connector(1)betw een the electronic

sw itch and the harness connector of the

signal line. The signal line w iring rem ains

in the vehicle and the connector should

be taped back to prevent rattles.

4. The location of the 3-pin connector w ill

vary according to vehicle (1). D isconnect

the sensor from the connector and

secure the signal line back to the m ain

portion of the harness and store it out of

sight(2).

5. R em ove the m agnetic sensor and install

the sun visor holding bracket.

6. R em ove the m agnetic pen holder from

the w indshield and return all three

com ponents back to the P arts

D epartm ent.

Battery MaintenanceThe battery charge is m onitored w hile the vehicle is at the V PC and before it leaves on the

transport. W hen the vehicle is having the Q C I perform ed at the center the check list

requires that the battery voltage be checked and m aintained to 12.65V m inim um .

In order to facilitate tracking vehicles in inventory, B M W has in place a B attery M aintenance

Program . The program uses :

Battery Log Form s

Battery Log B inder

C olored w indshield stickers (red, green, yellow and w hite)

The B attery M aintenance Program has three possibilities:

Vehicle in storage, battery disconnect sw itch rem oved

Vehicle in show room or display

Vehicle in storage, B attery disconnect sw itch left in the vehicle.

Vehicle in storage, battery disconnect switch removedA four w eek charging cycle has been established for these cases. All vehicles arrive w ith a

color coded sticker on the w indshield. The color corresponds to the w eek that the battery

m ust be charged. Also the vehicle w ill be provided w ith a B attery Log Form .

The Aportion (Vehicle R eceipt) of the Log Form m ust be com pleted during the Q C I

D isplay check and then has to be filed in the B attery C harge Log B ook under the

applicable color coded section. All the vehicles in that color section w ill have to be chargedthat w eek.

Vehicle in showroom or displayB ecause of the high consum er dem and on vehicles that are being displayed and not

driven, a four w eek charging cycle is not enough. For vehicles in the show room the

battery has to be charged as frequently as necessary to ensure that the battery never drops

below 12.5V. U se the Cportion of the log form (D isplay Vehicle - M onitored D aily) to keep

track of the charging and checking of the battery.

Vehicle in storage, battery disconnect switch left in the vehicle.

Since the battery disconnect sw itch is left installed and in the O FFposition the 3 m onthcharge cycle can be used. U se the Dsection of the B attery Log Form to docum ent w hen

the battery is charged.

U pon the sale of the vehicle, the B attery Log Form should be rem oved from the binder and

placed in the vehicle file for future reference.

Car Memory / Key Memory (CKM)This feature provides the flexibility of allow ing the ow ner to custom ize certain functions of

select vehicle system s and autom atically identifies users of the vehicle by a key

identification signal provided by the rem ote keyless entry system (FZV). C KM coding is

done at the tim e of delivery during the Q C I.

C ar & Key m em ory is m arketed as a com bined feature but is actually tw o separate

functions of the select vehicle control system s.

Car MemoryThe ow ner is provided w ith a list of available system functions that can be custom ized to

their liking. Prior to delivery, the D ISplus or M oD iC is used to encode the ow ners chosen

selections into the appropriate control m odules.

These choices becom e a perm anent function of the control m odule and can only be

changed by re-encoding w ith the D ISPlus or M oD iC at a B M W center.

Key MemoryThis feature provides the added convenience of identifying users of the vehicle w henever a

lock or unlocked signal is generated via the individual FZV keys. A m axim um of four FZV

keys can be used w ith the Key M em ory feature.

Each of the four keys generate a unique key identification signal (key num ber) that is trans-

m itted sim ultaneously w ith the lock/unlock signals to the G eneral M odule. Key Memory

does not respond to Lock/ Unlock requests from th e dr ivers door lock.

M ost of the key m em ory functions require the vehicle be configured using the KEY M EM -

O R Yfunction of the D ISplus or M oD iC . H ow ever, there are a few features that store set-

tings autom atically w ithout configuration such as IH K A blow er speed and tem p setting.

There are features that function as both a C ar & Key

M em ory feature.

Exam ple: the A utom atic S eat Adjustm ent feature is

encoded as a C ar M em ory Function w ith the follow ing

possibilities:

w hen unlocking,

w hen opening a door after unlocking

or not active at all.

If active, the seat positions are stored and reactivated by the Key M em ory function for

individual users of the car.

The C ar & Key M em ory feature has been integrated into the E38 and E39 since the 1999

m odel year (9/98 production). The C ar M em ory function w ithout key m em ory is also

available via C oding C onversion for E31, E32, E34 and E36 vehicles.(reference SI 09 03 98)

Car/Key Configuration and the Conversion FeatureThe ZC S C oding C onversion feature is still utilized for changing other system functions as

in the past. For exam ple: The Language D isplay C hange for the instrum ent cluster display

block is only available using the C oding C onversion feature.

Car/Key Memory Service Considerations

Replacing Car or Key Memory Configured Control ModulesIf a C ar/K ey M em ory capable control m odule becom es defective and needs replacem ent,

the specific custom ized data w ill be transferred over to the new replacem entunit duringthe ZCS encoding process.

If this is not possible due to extensive control m odule failure, the ow ner m ust be m ade

aw are of the situation and requested to provide the options they originally selected. For this

reason, it is advantageous to print the selected features as m entioned in the C AR & K EY

M EM O R Y configuration procedures.

FZV Key Initialization ProcedureAlso m entioned in the B M W Features section of this m anual, If FZV keys need

re-initializing, m ake sure they are initialized in the sam e order.

Technician AwarenessC ar M em ory/Key M em ory C onfiguration obviously changes the functionality of the system s.

B efore concluding a specific system is defective, review the C ar/Key m em ory selection for

the vehicle you are w orking on. This is m ost easily accom plished by selecting the PrintListfunction. There m ay be an ow ner selected function activated that is not a com m on

selection, causing m isunderstanding of the system 's function.

W hen w orking on a C ar/Key M em ory capable vehicle, avoid using the FZV keys. U se the

drivers door lock to lock and unlock the vehicle to m aintain the ow ners m em orized settings.

If settings had to be m odified as part of repair procedure, inform the client advisor of the

situation so that they can inform the vehicle ow ner.

BMW Engine Oil Service

All m odels (except M R oadster/M C oupe up to 2001) feature extended O il Service intervals

of 15,000 m iles. This is a result of im provem ents in oil quality and durability provided by

synthetic oils. O il changes based on tim e have also been extended from 1 year to a

m axim um of 2 years unless indicated otherw ise by the Service Indicator System .

The B M W O il Service includes other com prehensive vehicle checks and m aintenance

because the service intervals are further apart. R efer to the Service M aintenance C hecklist

for the exact procedure for the vehicle that is being serviced as contents of the service do

vary.

Workshop Hints

BMW Inspection I

The advanced technologies used in engine m anagem ent system s and im provem ents in low

m aintenance engine design have reduced the required m aintenance in each Inspection

Service significantly.

B ecause the vehicle w ill be visiting the w orkshop less frequently it is very im portant that the

m aintenance and any tim e dependent services be carried out thoroughly and correctly.

Follow the S ervice M aintenance C hecklist for the necessary steps required to properly

com plete the service.

Engine Coolant ServiceThe engine coolant m ust be replaced every four years. R efer to R epair m anual17 00 005

for instructions on draining and refilling coolant. Pay attention to engine specific

instructions.

Oxygen Sensor ServiceThe oxygen sensors should be replaced at intervals of 100,000 m iles.

Spark Plug ServiceB M W engines from M odel Year 1999 com e equipped w ith Longlife Platinum Spark Plugs.

The service interval of the longlife plug is 100,000 m iles, except for application in the S62engine w hich is an interval of 60,000 m iles.

B e aw are that earlier m odels m ay have been fitted w ith the Longlife spark plugs during a

previous service, look for a label along the radiator support or shock tow er indicating the
