Door Windows

air-
bag to door.

Sedan and Sport Wagon doors are similar. There are two win-
dow rails in each front window regulator, only one in the rear.
Otherwise the front and rear regulators are similar.
WARNING-
E39 cars are Wed with side-impact airbags in the front
doors. Some are equipped with
airbags in the rear doors
as well. When servicing the door windows on cars with
side-impact airbags, always disconnect the negative
(-)
battery cable. See 721 Airbag System (SRS) for cau-
tions and procedures relating to the
airbag system.
Prior to disconnecting the battery, read the battery dis-
connection cautions given at the front
001 General
Warnings and Cautions.
NOTE-
Because window operation is electronically controlled, a win-
dow motor does not have mechanical endpositions. For this
reason it can be removed and installed with the window in
any position and does not need reinitialization.
Front window regulator removing and
installing
NOTE-
BMW recommends removing the window regulator and mo-
tor as one unit, then separating the two on the bench.

ELECTRONIC ~MMOBILIZATION (EWS)
E39 cars are equipped with a passive theft-prevention sys-
tem. The Electronic Immobilization System (EWS) makes it
impossible to
startthe engine using any means other than the
special lkeys furnished with the vehicle.
NOTE-
Replacement EWS control modules or DME control modules
must be electronically aligned to each before the vehicle will
start. This requires the use of the BMW Service Tester
(DIS-
plus, GT1, or MoDiC). Without alignment, the engine will not
crank (for example: swapping a
known good DME control
module into another vehicle for test purposes will result in a
no crank situation).
In the EWS system, the ignition key is embedded with
acom-
puter chip (EEPROM) and coded. The key communicates
with the vehicle using a transponder in the lkey and a ring an-
tenna surrounding the steering lock cylinder. Up to
6 replace-
ment keys are permissible. Only an authorized
BMW dealer
can provide replacement keys.
