This Service Information bulletin supersedes S.I. 11 06 98 dated November 1998 (which did not include Service Action Label Instructions and Warranty Information) and should be removed and discarded from your S.I. binder.
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
Changes to this revision are identified by asterisks.
SUBJECT:
Oxygen Sensor Update and DME Reprogramming
MODEL:
E36 with M44 engine
Situation:
The oxygen sensors of the affected vehicles listed below may over time develop poor internal electrical connections which will cause the check engine light to illuminate.
If this situation occurs the possible fault codes set in the DME are:
^ FC 10, Oxygen Sensor Pre Catalyst and/or
^ FC 12, Oxygen Sensor Post Catalyst
Vehicles Affected:
This Service Action involves E36 vehicles with M44 engines which were produced from 1/96-12/96.
In order to determine if a specific vehicle is affected by this Service Action, 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 to be considered as the only deciding factor.
Correction:
Replace both oxygen sensors (pre cat regulating sensor and post cat monitoring sensor) and reprogram the Engine Control Module (DME) using DIS or MODIC P14.O programming software or higher.
Procedure:
^ Read and print out DME fault codes.
^ Any oxygen sensor fault codes listed in the situation section above should be ignored.
^ Troubleshoot and repair other DME fault codes using the DIS tester instructions as necessary.
^ Clear all fault codes stored in the DME
*^ Reprogram the DME using P15.O programming software or higher (available as of CD 15). Refer to the attachment for programming instructions and to S.I. 12 02 98 for programming hints if problems are encountered.
^ After reprogramming the ECM/DME, one of the following part numbers for a programmed control unit" must be displayed on the ECM/DME identification screen: *
^ Replace the regulating and monitoring oxygen sensors as outlined in the E36 repair manual group 11 section 11 78 510.

Service Action Label Instructions:
This Service Action has been assigned code number 221. After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-095) and:
a) emboss your BMW dealer warranty number in the middle of the label (1);
b) punch out code number 221 printed on the label and,
c) affix the label to the B pillar as shown:
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on top of another one because a number from an underlying label could appear in the punched-out hole of the new label.
Warranty Information:
Reimbursement for this Service Action will be provided through Campaign Entry.
The notification letter will be sent to all customers with affected vehicles.
