Maintenance
Spark plugs, replacing
E39 engines use a coil-over-spark plug configuration, with
one ignition coil above each spark plug. Sparks plugs should
be removed only after the engine has cooled.
Remove engine
cover(s) over ignition coils:
Remove acoustic cover over fuel injectors
I intake
manifold.
6-cylinder engine: Remove oil filler cap.
Remove plastic trim covers (arrows).
Remove cover hold-down bolts. Remove coil
cover(s)
6-cylinder engine: Temporarily reinstall oil filler cap to
keep out contaminants.
Remove ignition coil grounding harnesses (arrows). 6-cylin-
der coils shown,
V-8 engine is similar.
< Remove ignition coils:
Pull up on spring clips to disconnect ignition coil harness
connectors.
Remove coil mounting bolts. Pull coils up and off spark
plugs.
- Remove spark plugs.

Engine identifying features
4 The M52 engine (MY97-98 528i) used a single on-off vari-
able intake valve timing system (called VANOS). The cylinder
block is cast iron and the cylinder head is aluminum. The en-
gine management system is Siemens MS 41
.I and features
NGK-type (0-5 volt) oxygen sensors.
NOTE-
VANOS is an acronym based on the German words Variable
Nocltenwellen Steuerung (variable camshaft timing).
4 The M52 TU engine (MY99-00 5281) and the M54 engines
(MY01-02 525il530i) are fitted with double VANOS. The en-
gine
blocits are constructed of aluminum alloy with cast iron
cylinder sleeves.
4 The double VANOS (variable camshaft control) system incor-
porates true variable control of both the
intake and exhaust
camshafts, as compared to the single VANOS system on the
M52 engine
(onloff control of the intaite camshaft only).
The M54 engines use a fully electronic throttle control (drive
by wire). There is no accelerator cable connecting the throttle
pedal to the throttle housing in these cars.

I Engine-General
The M62 90" V8 engine uses four valves per cylinder, double
overhead camshafts and light alloy cylinder head and cylin-
der
bloclc engine construction.
On 1997 and 1998 540i models, Bosch engine management
systems are utilized. Table a lists engine management sys-
tem applications.
4 For the 1999 model year, the M62 TU VANOS engine was in-
troduced to the 540i models. This engine is primarily a carry-
over from the earlier M62 engine, but contains many unique
identifying components and technology:
Variable camshaft timing (VANOS) for the intake valves.
Bosch ME 7.2 engine management system with electronic
throttle control. There is no accelerator cable connecting
the throttle pedal to the throttle housing in these cars.
Compact water-cooled generator (alternator).
E39 vehicles are equipped with sophisticated self-diagnostic
engine management systems. These systems monitor and
store diagnostic fault information. If the malfunction indicator
lamp (MIL) illuminates, the first diagnostic test should be to
connect a dedicated scan tool for BMW automobiles and in-
terrogate the fault memory.
If the malfunction indicator light (MIL) comes on orflashes, it
indicates that an emissions-related fault has occurred and
that fault information is stored in memory within the ECM.
4 The MIL in E39 cars displays one of these warning graphics
in the instrument cluster.
The diagnostic capabilities of these systems have the poten-
tial to save hours of diagnostic time and prevent incorrect
5 placement. See OBD On-Board Diagnostics.

If the MIL (Malfunction Indicator Light, also may be
called "Check Engine" or "Service Engine Soon" light)
is illuminated, see
OBD On-Board Diagnostics for
DME fault code information.
It orhersysrem faults have been detected, as indicated I
by an ~llum~nated ABS, SRS orASC/DSC ~arning light,
see the appropriate repair group in this manual or an
authorized BMW dealer for more information on fault
codes.
NOTE- Engine removal procedures are similar for all 6-cylinder
models. When differences
exist, they are noted at the be-
ginning of each step. Engine are referred to by engine
code. See
100 Engine-General for engine code and appli-
cation information.
@ Be sure to cover all painted surfaces before beginning the
removal procedure. As an aid to installation, label all com-
ponents, wires and hoses before removing them. Do not
reuse
gaskets, O-rings or seals during reassembly.
The
intake manifold must be removed on &cylinder mod-
els before the engine can be removed.
WARNING-
Due to risk of personal injury, be sure the engine is cold be-
fore beginning the removal procedure.
