SUBJECT
Service Engine Soon Lamp (MIL) On with NOx Sensor Faults Stored
MODEL
F25 (X3 xDrive 28d)
F30 (3 Series Sedan 328d)
F31 (3 Series Sport Wagon 328d)
With the N47T engine produced to 7/2014
F02 (7 Series Sedan 740Ld)
F10 (5 Series Sedan 535d)
F15 (X5 xDrive 35d)
With the N57T engine produced to 7/2014
SITUATION
The Service Engine Soon lamp (MIL) is on with either of the following nitrogen oxide (NOx) sensor faults stored:

2B6200 - NOx sensor before DeNOx catalytic converter, plausibility: Sensor self-diagnosis of sensitivity

2B6300 - NOx sensor After DeNOx catalytic converter, plausibility: Sensor self-diagnosis of sensitivity
These stored faults would not cause a problem with engine performance.
This NOx self-diagnostic routine is performed only after the engine has been shut off.
In some situations, the diagnostic function of both NOx sensors can be too sensitive when sampling the residual
exhaust gases, leading to an erroneous fault being set.
CAUSE
Unfavorable DDE software diagnostics
CORRECTION
Using the latest version of ISTA, complete the recommended test plans to identify if the sensor is defective or
not.
Program the vehicle using ISTA/P 2.53.2 or a more recent version.

Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the
latest software.
Always connect a BMW approved battery charger/power supply (SI B04 23 10).
For information on programming and coding with ISTA/P, refer to Centernet / Aftersales Portal / Service /
Workshop Technology / Vehicle Programming.
If after programming, any of the faults listed above continue to be stored following a few driving cycles, continue
diagnosis with ISTA and replace the sensor.
WARRANTY INFORMATION
Covered under the terms of the BMW New Vehicle/SAV Limited Warranty or the BMW Certified Pre-Owned
Limited Warranty.

diagnosis system – checking faults)
Refer to KSD2
Connect an approved battery
charger/power supply (indicated in
KSD2 as “Charging battery”)

Programming / encoding control unit(s)
And:
61 21 528
And, as necessary:
61 00 006
And:
61 00 730
Labor operation code 00 00 006 is a Main labor operation. If you are using a Main labor code for another
repair, use the Plus code labor operation 00 00 556 instead.
Refer to KSD2 for the corresponding flat rate unit (FRU) allowance. Enter the Chassis Number, which
consists of the last 7 digits of the Vehicle Identification Number (VIN). Click on the “Search” button, and then
enter the applicable flat rate labor operation in the FR code field.

Even though work time labor operation code 61 00 006 ends in “006,” it is not considered a Main labor
operation.
Work time (WT) labor operation 61 00 006 requires an individual punch time.
If a control module or component was working properly and/or had no related faults stored prior to vehicle
programming and it fails to program correctly or requires initialization, this additional work must be claimed with
separate labor operations under the defect code listed above; refer to KSD2.
Repairs to control modules and components with pre-existing conditions are not eligible to be claimed under
the defect code listed in this bulletin.
Other Repairs
If performing ISTA diagnostics and related test plans results in other eligible and covered work, claim this
work with the applicable defect code and/or labor operations listed in KSD2.
