Sport Wagon models
In order to provide a wide, ilat iloor in the cargo compartment,
the rear suspension on the Sport Wagon is unique to itself.
The shoclcabsorber is attached diagonally between the lower
swing arm and a mounting bracket on the subframe. The
spring on each side is mounted between a perch at the top
oi
the wheel bearing carrier and the bottom of the cargo com-
partment floor.
Starting with
1999 Sporl Wagon models, a self-leveling air
suspension system with electronic height control (EHC) was introduced. The system is standard on
V-8 models and op-
tional on 6-cylinder models.
On models fitted with electronic height control (EHC) rear
suspension, the standard coil springs are replaced by air
springs. Air pressure in the air springs is automatically con-
trolled by the
EHC system to compensate for ride height and
load variations.

Differential oil level, checking
The E39 differential is filled with lifetime oil that ordinarily
does not need to be changed. BMW recommends using only
a specially formulated synthetic gear oil
(SAF-XO) that is
available through an authorized BMW dealer parts depart-
ment. For additional information on this lubricant and any oth-
er lubricants that may be compatible, contact an authorized
BMW dealer service department.
< Check rear differential oil level at filler plug (arrow).
- Check lubricant level with car on a level surface:
Level is correct when fluid just reaches edge of filler hole.
If necessary, top up fluid.
* Replace filler plug sealing ring.
Install and tighten oil filler plug when oil level is correct.
NOTE-
Use either a 14 mm or 17 mm Allen socket to remove the
drain plug.
If car is raised in the air. it should be level when
checkino " or filling final drive fluid level.

Bumpers
The front and rear bumpers are clad in high quality
deform-
able plastic and, at solid barrier impact speeds of 4 kph (2.5
mph), provide protection with virtually no damage to the
bumper
orthe vehicle. In addition to hydraulic dampeners.
which absorb the initial impact energy, these bumpers are
backed by compressible tubes. These deform in a controlled
manner at impact speeds greaterthan that
forwhich bumpers
and hydraulic dampeners are designed. This helps avoid ex-
pensive damage to the body at impact speeds up to 14 kph (9
mph).
The E39 Sport Wagon was introduced to the US market in
911 998 (model year 1999). It shares many components with
the E39 sedan and is identical to it from the B-pillar forward.
US
marltet 5 Series Sport Wagons are available in two vari-
ants:
6-cylinder
(5251, 528i) powered by the 2.8 liter M52 TU en-
gine (1 999) or the 2.5 liter M54 engine (2000 and later)
* V-8 (540i) powered by the 4.4 liter M62 TU engine
The wheelbase of the Sport Wagon is the same as the sedan.
Howeverthe body is 30
mm (1.2 in) longer and 10 mm (0.4 in)
higher.
The Sport Wagon rear suspension was redesigned to elimi-
nates the upper rear spring strut mounting on the E39 sedan.
The use of separate coil springs and
shoclc absorbers results
in a flat, wide floor in the cargo area. See
300 Suspension,
Steering and Brakes-General.
The self-leveling air spring suspension system (electronic
height control or EHC) is standard on Sport Wagon V-8 mod-
els and optional on 6-cylinder models.
