Fuel pump fuse and relay
Troubleshooting of any fuel pump fault should begin with
checking the fuel pump fuse and the fuel pump relay. The
DME main relay should also be checked. The fuel pump relay
is located behind right side luggage compartment interior
panel.

- Fuse 31 in glove compartment fuse panel supplies power to
coil side of fuel pump relay. Engine control module (ECM)
supplies switched ground to relay. During starting, fuel pump
runs as long as ignition switch is in START position and con-
tinues to run once engine starts. If electrical system fault in-
terrupts power to fuel pump, engine will not run.
. .
Operating fuel pump for tests
- To operate fuel pump for testing purposes without having to
run engine, bypass fuel pump relay to power pump directly.
< To run fuel pump, open luggage compartment and release
right side trim panel.

Manual Transmission
Manual transmissions installed in the 5 Series are normally
filled with a "Lifetime" manual transmission fluid
(BMW MTF
LT-I) and do not require periodic fluid changes. Transmis-
sions filled with MTF LT-I lifetime oil are identified with a yel-
low label near the transmission fill plug labeled "Lifetime Oil
MTF-LT-1".
Transmission fluid level, checking
- Drive vehicle for a few miles to warm transmission.
- Raise and safely support vehicle to access transmission
filler plug.
CAUTION-
Make sure the car is stable and well supporfedat all times.
4 Remove side filler plug (B). Insert finger into hole to check
fluid level. If fluid level is up to bottom of filler hole (finger is
wetted by transmission fluid), level is correct.
NOTE-
* Check and fill transmission with car on level surface.
5-speed transmission shown in illustration. 6-speed trans-
mission is similar.
- Install and torque filler plug.
Tightening torque

Transmission fluid, replacing
- Drive vehicle for a few miles to warm transmission.
- Raise and safely support vehicle to access drain plug.
CAUTION-
Make sure the car is stable and well supported at all times.
Use a professional automotive lift
orjack stands designed
for the purpose.
A floor jack is not adequate support.
Check that the
fill plug is not seizedprior to draining
transmission fluid.

I Automatic Transmission Automatic transmission fluid (ATF)
The E39 automatic transmission is filled with either Dexron Ill
ATF or Texaco 80728, a life time oil.
CA UTIOI\C
Use only the transmission fluid that is approved for use by
BMW All other fluids will cause non warrantable transmis-
I sion damage.
Mixing different types of transmission fluids will lead to
transmission failure.
NOTE-
The type of transmission lubricant used can be found on a
stickeron the transmission pan. Dexron
111ATF (blacksticker)
reads "ATF-Oil': Special life time oil (green sticker) reads
'Life-Time Oil': If in doubt, consult an authorized
BMW dealer
for alternate fluid use and current information regarding
transmission operating fluids.
ATF level, checking
Check ATF level if there is evidence of a leak, a complaint re-
lated to fluid level or afler transmission repairs.
The automatic transmission is not equipped with a dipstick.
Checking the ATF level requires that the transmission be at
operating temperature during the checking procedure.
NOTE-
Vehicle must be level throughout tests
- Drive vehicle to warm up ATF to operating temperature.
- Connect BMW diagnostic scan tool DiSplus, MoDiC, GTI or
equivalent to determine transmission oil temperature.
ATF level checking
Fluid temperature
30' - 50°C (85' - 120" F)
- With engine running, switch on air conditioning to increase
engine idle speed.
- Apply parking brake.
- While applying foot brake firmly move gear shift selector
lever through
all gear positions, pausing in each gear briefly.

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.

- Remainder of installation is reverse of removal.
- Check and, if necessary, set differential oil level. See Differ-
ential oil level, checking.
