SUBJECT: Voluntary Emissions Recall Campaign No. 99E-A01
MODEL: E36 - 323i and 328i with M52 engine produced 6/95 - 12/98
E36 - M3 with S52 engine produced 1/96 - 12/98
E39 - 528i with M52 engine produced 3/96 - 8/98
Z3 - with M52 engine produced 7/96 - 9/98
Z3 - with S52 engine produced 1/98 - 1/99
Situation: BMW of North America, Inc. has initiated a Voluntary Emission-
Recall Campaign to correct vehicles that may have a faulty
crankshaft position sensor. A customer notification letter will be
sent out by May 1999. This action will address the illumination of
the "Check Engine" lamp and the following faults being set in the
Engine Control Module (ECM/DME):
Fault Code 83 - Crankshaft position sensor
Fault Code 244 - Crankshaft segment timing
Cause: Internal failure of the sensor
Affected This recall involves E36,E39 and Z3 vehicles with M52 and S52
Vehicles: engines which were produced from 6/95 - 1/99.The procedure
given in this bulletin must be performed on all affected vehicles
identified on DCS. (A copy of the letter which will be sent to all
affected customers in a staggered mailing is attached to this S.I.)
In order to determine if a specific vehicle is affected by this
Recall , it will be necessary to utilize the "Service Menu" of the
DCS (Dealer Communication System). Based on the response of
the system, either proceed with the corrective action or take no
further action.

Correction: The crankshaft position sensor needs to be replaced with the
same type of sensor that is currently being used on the M52TU
engine. Along with replacing the sensor an adapter harness must
also be installed in order to supply the sensor with a 12V
operating voltage instead of the 5 volts currently being supplied
by the DME.
NOTE: SOME VEHICLES LISTED IN DCS MAY ALREADY
HAVE THE NEW STYLE SENSOR INSTALLED, FOR THESE
VEHICLES A CHECK/VERIFICATION WILL ONLY BE
NEEDED.
Procedure: The following steps must be followed when replacing the original
M52 crankshaft sensor with the new M52TU sensor.

1. Remove the crankshaft position sensor which is located
below the starter motor.
Remove the Sensor (1)
If the sensor currently installed in the vehicle has a
connector directly on the sensor which can be
disconnected, then the new sensor is already installed.
No further action is required and the DCS contact can
be closed.
Note: Illustration shows location of component with air filter
housing and air mass meter removed. It is not necessary to
remove these components to perform this repair.
2. The electrical connection of the crankshaft sensor to the
engine harness is located below the intake manifold.
To access this connector, the cap of the oil filter housing
should be removed and the oil filter and housing should
then be covered to prevent dirt from getting onto the oil
filter.

3. Disconnect the crankshaft position sensor (1) from the
engine harness.
Note: This illustration shows the plug connectors with the
intake manifold removed.
It is not necessary to remove the intake manifold in
order to gain access to these connectors and complete
this repair.
4. Remove the fuel rail cover and unplug the VANOS solenoid
valve plug connector (2).
5. Install the new crankshaft position sensor (1) P/N 12 14 1
709 616 and O-ring P/N 12 14 1 748 398.

6. Install adapter harness P/N 12 51 4 592 703.
a. Connect (1) to the new crankshaft position sensor.
b. Connect (2) to the engine harness connector which
was previously connected to the old crankshaft
sensor located below the intake manifold.
c. Connect (3) to the VANOS solenoid valve located on
the VANOS unit.
d. Connect (4) to the engine wiring harness connector
which previously connected directly to the VANOS
solenoid valve.
7. After the adapter harness has been installed secure the
harness lead going to the VANOS solenoid valve (1) to the
VANOS oil line with 2 cable ties (3).
Note: The harness lead going to the VANOS solenoid valve
should not be under tension. The harness lead should be
able to move.

(in the engine compartment) next to the Vehicle Emission Control
Label.
For California centers only it is required by the California Code of
Regulations that an executed orange "Vehicle Emission Recall -
Proof of Correction" certificate (SD92-084, see illustration) be
provided to each customer (for vehicles registered in the state of
California) once the Recall on their vehicle has been completed.
Note: Additional labels can be ordered from Product Engineering (a
pre-printed order form is enclosed).
