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.
