SUBJECT
[NEW] Service Action: Replace Spark Plugs (N63, N74, S63)
MODEL
E70, E71, E72, F01, F02, and F07 with N63, N74, and S63 engines produced 3/11/09 to 7/22/09
SITUATION
The spark plugs in the affected vehicles may not adhere to the durability requirements.
CAUSE
Micro-cracks in the ceramic insulator of the spark plug may occur, which could result in engine misfiring and rough running, especially at higher
engine speeds.
If this were to occur, the "Service Engine Soon" lamp would be illuminated and the engine may go into the emergency operation program.
Note:
2010 BMW 760Li (F02) V12-6.0L Turbo (N74) Page 215
The vehicle can still be operated were this fault to occur; however, the customer should proceed directly to the nearest BMW repair facility.
[NEW] AFFECTED VEHICLES
This Service Action involves E70, E71, E72, F01, F02, and F07 vehicles with N63, N74, and S63 engines which were produced from 3/11/09 to
7/22/09.
In order to determine whether a specific vehicle has had this Service Action completed or is affected by this Service Action, first check the B-pillar
label for code number 548. If code number 548 has been punched out, the campaign has already been performed. If code number 549 has not been
punched out, it will be necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader. Based on the
response of the system, either proceed with the corrective action or take no further action.
[NEW] PARTS INFORMATION
PROCEDURE
[NEW] Replace all spark plugs as described in the model-specific REP documents as of ISTA D2.18.
LABEL INSTRUCTIONS
This Service Action has been assigned code number 549. After the vehicle has been checked and corrected, if necessary, obtain a label (SD 92-366)
and:
A. Emboss your BMW center warranty number in the middle of the label (1):
B. Punch out code number 549 (2) 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.
