20 PIN DIAGNOSTIC SOCKET DELETION
Model: E39,E46,E52,E53
Production Date: E46 from 6/00
E39,E52,E53 from 9/00
For model year 2001 the E39, E46 and E53 will eliminate the 20 pin diagnostic connector
from the engine compartment. The 16 pin OBD II connector located inside the vehicle will
be the only diagnosis port.
The E38 and Z3 will continue to use the 20 pin connector.
The 16 pin OBD II connector has been in all
BMWs since 1996 to comply with OBD II
regulations requiring a standardized diagnostic
port.
Previously before 2001, only emissions relevant
data could be extracted from the OBD II
connector because it did not provide access to
TXD (D-bus). The TXD line is connected to pin
8 of the OBD II connector on vehicles without
the 20 pin diagnostic connector.
The cap to the OBD II connector contains a
bridge that links KL 30 to TXD and TXD II. This
is to protect the diagnostic circuit integrity and
prevent erroneous faults.
The OBD II connector is located in the drivers
footwell to the left of the steering column of E39,
E46 and E53 vehicles.
Special tool 61 4 300 is used to connect to the
20 pin diagnostic lead of the DIS until the intro-
duction of the DISplus.

2001 E39 UPDATE
Model: E39 (525i/iT, 530i, 540i/iT, M5)
Production Date: From 9/00
For Model Year 2001 the E39 will receive it’s first cosmetic facelift since series launch in
1997. In addition to the visual changes, several systems have been enhanced and updat-
ed. A new model has also been added, the 525i/it, making 6 variants of the E39 possible.

Engines
Two M54 engine variants will be added to the E39 for the 2001 M.Y. starting production
9/00. The M54 B30 and M54 B25. The M54 B30 engine will replace the M52 B28TU of
the 528i and become the 530i. The M54 B25 engine equipped 5 Series will create a new
model, the 525i, it will become the entry level 5 series.
The design objectives for the M54 engine were:
 Lower emissions
 Maintain fuel economy
 Increase power and performance.
The 540i/it will use the A5S 440Z automatic transmission with Steptronic as standard
equipment and continues to have the optional 6 speed manual. The 525i and 530i
models will use the A5S 390R (GM 5) with Steptronic as optional equipment until March of
2001 at which time the GM5 will be replaced by the A5S 325Z (5HP 19).
Please refer to the 2000 Systems Diagnosis course material ST 039 for information concerning the
M54 engine family.

Body Work
The sheet metal remains unchanged, however several touches have been made to
freshen the appearance of the 5 Series.
The front, rear and side impact strips have been painted body color. The 540i/it has a
chrome insert along the upper edge of the impact strips.
The kidney grille inserts on all models have been widened to give the car’s “face” a more
aggressive appearance.

Fog lights
New circular fog lights with convex plastic lens-
es are tucked neatly into the corners of the new
front air dam. The new lights use an H8 12V
35 W halogen bulb.
Park Distance Control
The 2001 E39 will have Front and Rear PDC available as an option. The system operates
just as the E38 and E53 with the same system. The vehicle is fitted with a PDC switch
located on the SZM. Activation is automatic with reverse gear engagement, but may be
deactivated with the switch. The switch may also be used to activate the system. Criteria
for operation remain unchanged from previous systems.

Head and Tail Lights
The head and tail lights of the 2001 E39 have received a new look, utilizing optical wave
guide technology. The wave guides are an innovation that are not only aesthetically
pleasing, but also enhance safety.
Head Lights
The front headlights have been completely redesigned, however they fit into the existing
body without any sheet metal changes. The high and low beam headlights are free-form
reflectors and no longer use the glass lenses. The turn signal has been given its own
circular lens next to the low beam.
