THE MIL IS ILLUMINATED WITH OXYGEN SENSOR FAULTS STORED

MODEL
E-Series
F90

Model Description
M5 Sedan

Production Date
All

Affected Option Code
All

SITUATION
One of the following faults may be stored in the digital motor electronics (DME), either as part of diagnosing
a different issue; and/or an illuminated malfunction indicator lamp (MIL).
Fault code

Control module

13900

DME

Fault code text
Oxygen sensor after catalytic converter, from rich to lean:
Delayed response

Or:
12B011

DME

Oxygen sensor 2 after of catalytic converter, from rich to lean:
Delayed response

This situation is not associated with any drivability complaints.

CAUSE
An unfavorable DME diagnostic calibration may cause a fault code to be erroneously stored. These faults
will cause the MIL to illuminate.

CORRECTION
If the current vehicle I-level is below S15A-19-07-530:

Program the vehicle using ISTA 4.21.3x or later (available late January 2020)

If the current vehicle I-level is S15-19-07-530 or higher:

Continue with ISTA Diagnostics

PROCEDURE
For conditions that are similar to the situation described:

1. Perform diagnosis with the latest version of ISTA Next and verify fault code 13900 or 12B011
has been stored.
2. Evaluate the current vehicle I-level:
a. If

the I-level is below S15A-19-07-530, update the vehicle using ISTA 4.21.3x or higher to the
appropriate I- level shown below:
Model
F90 (M5 Sedan)

1. If

I-level
SA15A-19-11-555 or higher

the current vehicle I-level is S15-19-07-530 or higher, continue with ISTA Diagnostics.

Programming Notes:
Note that ISTA Next 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, refer to CenterNet / TIS / Technical Documentation /
Programming and Diagnostics / Programming Documentation.

WARRANTY INFORMATION
During this workshop visit, the affected vehicle may also show one or more programming and encoding
Technical Campaign repairs open, the programming and encoding procedure may only be invoiced one
time.
Update the vehicle to the required I-level or higher by performing and submitting for one of the open
Technical Campaigns instead. Please be sure to also perform any additional work (before and/or
after) the campaign repairs require and/or close the remaining open programming and encoding
Technical Campaign repairs as outlined in the corresponding Service Information Bulletin.
Only if the above situation does not apply, the BMW software solution is then:
Covered under the terms of the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks.
This repair is also covered by the terms State-specific Emissions Warranty (dependent on the vehicle’s
model year, state of registration and its inclusion on the model-specific list of covered components).
Afterwards, it is then covered under the terms of any active and remaining BMW Certified Pre-Owned
Program coverage that applies to the BMW vehicle.

Programming and Encoding - Vehicle Control Units (RO and Claim Comments Required)
The programming procedure automatically reprograms and encodes all vehicle control modules which do
not have the latest software I-level. If one or more control module failures occur during this programming
procedure:

Please claim this consequential control module-related repair work (including the IRAP Control
Unit Recovery procedure as required, refer to the SIB in AIR) under the defect code listed in
this bulletin with the applicable AIR labor operations.
Please explain this additional work (The why and what) on the repair order and in the claim comments
section
For control module failures that occurred prior to performing this programming procedure:

When covered under an applicable limited warranty, claim the applicable test plan and the
corresponding control module-related repair work using the applicable defect code and labor
operations in AIR (including diagnosis with separate punch times).
Other Repairs
If other eligible and covered work is performed as a result of performing the ISTA diagnostics and related
test plans, claim this work with the applicable defect code and the labor operations that are listed in AIR
(including diagnosis with separate punch times).
