Engine-General
This section covers system descriptions and general informa-
tion on engines and engine management systems. Also cov-
ered is basic engine troubleshooting.
For specific repair procedures, refer to the appropriate repair

E39 models are fitted with a variant of either an inline 6-cylin-
der or a
V-8 engine. See Table a.

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.

Cylinder Head Removal and Installation
This group covers cylinder head removal and installation as
well as cylinder
headlvalve diagnostic procedures.
In the procedures in this repair group, engines are referred to
by engine code. If necessary, see
100 Engine-General for
engine code and application information.
The information given in this repair group assumes that the
engine is installed in the engine bay. On the
6-cylinder en-
gines, the VANOS control unit must be removed in orderto re-
move the cylinder head from the engine block. On
M52TU
and M54 engines, camshafts must be removed from the cylin-
der head before the head is removed.
The cylinder head removal and installation procedures for the
M62 V-8 are also included, butthe proceduresforthe M62TU
V-8 with VANOS are not provided.
For cylinder head and valvetrain reconditioning information,
see
116 Cylinder Head and Valvetrain.
For specific repair procedures, refer to the appropriate repair
group:
020 Maintenance
116 Cylinder Head and Valvetrain
117 Camshaft Timing Chain
170 Radiator and Cooling System
610 Component locations
NOTE-
If a head gasket problem is suspected, a compression test or
leak-down test will usually detect the fault See Diagnostic
Testing later
in this group.
Special tools
Special BMW service tools are required to properly remove
and install the cylinder head on engines covered by this man-
ual. The special tools are used to time the valvetrain to the
crankshaft, and to remove the VANOS control unit, the cam-
shafts and the
Tom (El2) head bolts. Read the entire proce-
dure through before beginning the job.
