Gab schon oft Probleme mit den nicht originalen KWS.
Würde dir einen originalen von BMW empfehlen.
Meiner war auch mal kaputt seit ich den neuen von BMW drinne habe keine Probleme mehr.

Bei mir war erst der KWS kaputt und gleich danach der NWS!!

Hast du dein Fehlerspeicher nochmal auslesen lassen, seitdem du den originalen KWS verbaut hast?

Zitat von a.tec

Habe jetzt den originalen KWS mit Adapter verbaut' doch der wagen läuft nun so gut wie gar nicht mehr, hat Fehlzündungen und Aussetzer. Auch geht er im Leerlauf aus, wenn man ihn mit gas auf über 2000 um in hält geht es einigermaßen... hat jemand Tipps? Ich würde auf DME tippen, aber das kostet halt auch wieder. Muss man beim DME Tausch auch die passende WFS verbauen, oder geht das mit der die drin ist?

Was für ein Adapter?? Kauf den originalen für Deinen Motortyp und fertig. Mache den NWS gleich mit!

so ist es, Sir M-Opa
es gab sogar eine Rueckrufaktion fuer meinen M3 in USA Ausfuehrung. Meiner wurde letztes Jahr kostenlos ausgetauscht. Da gibt es den KWS Sensor neu mit 12V anstatt der alte 5V, einen extra Kabelbaum mit Steckern dran.
Hab die SI nur auf Englisch, aber da sind alle VIN angegeben, die es betrifft:

GROUP 12 12 10 99 Woodcliff Lake, N.J. July 1999 Engine Electrical Product Engineering
Perform the procedure outlined in this Service Information on all affected vehicles the next time they are in the shop for maintenance or repairs and on every affected vehicle prior to retail.
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 Vehicles: This recall involves E36,E39 and Z3 vehicles with M52 and S52 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. The Chassis Number Ranges listed below are only for informational purposes and are not tobe considered as the only deciding factor.

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 adapterharness 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.

Procedure: The following steps must be followed when replacing the original M52 crankshaft sensor withthe new M52TU sensor.

1. Remove the crankshaft positionsensor 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 theplug 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 616and 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.
