LDW (LANE DEPARTURE WARNING): STEERING WHEEL VIBRATION
NOT STRONG
This Service Information Bulletin (Revision 2) replaces SI B66 21 19 dated December 2019.
What’s New (Specific text highlighted):
• Model

MODEL
E-Series

Model Description

G01

X3 Sports Activity Vehicle

G02

X4 Sports Activity Coupe

Production Date
Up to
July
1, 2019

Affected Option Code
5AS – Driving Assistant
or
5AT – Driving Assistant
Plus,
but without option
710 – M Leather
Steering wheel

Note: There was a technical change implemented for the LDW vibration system. Starting with Model Year
2020 vehicles, the vibration actuator is no longer installed in the steering wheel (the function is now
performed by the EPS). Therefore, this SI does not apply to vehicles (MY 20) produced from the production
date listed above.

SITUATION
Lane Departure Warning (LDW) steering wheel vibration is perceived as being not strong enough,
even with the strongest setting selected via the iDrive menu.

CAUSE
Software in the vibration actuator and /or steering wheel component.

CORRECTION
· Perform a software update dependent on the current integration level (I-level)
· Perform Test Plan AT6131_BDC11LRE,
and /or
o Remove actuator insulation
· Replace the vibration generator

PROCEDURE
1. Verify that the Intelligent Safety setting for vibration level is set to “strong”.
2. Duplicate the issue via a test drive.
3. Determine the current I-level of the vehicle via the Key Read or AIR.

a. If it is lower (older) than S15A-19-03-500, program and encode the vehicle before
moving to step 4
b. If it is at S15A-19-03-500 or higher, proceed as outlined below
4. Before performing the test plan for the first time, do the following:
a. Disconnect the ICOM
b. Allow the vehicle to enter sleep mode
c. Vehicle must sleep for 5 minutes
Note: Vehicle is asleep when the illumination of the hazard light button backlighting goes out.
5. Connect the ICOM and start new session.
6. Using text search, find test plan by searching “Steering wheel module”.
a. Path: Vehicle management/ Trouble shooting/ Text search
7. Select test plan titled “steering wheel electronics” from the result list.
a. Test plan titled when open “AT6131_BDC11LRE”
b. Display test plan and perform option for “checking vibration actuator”
c. Run this test plan at least 8 times in succession
8. Take vehicle for test drive and verify functionality.
9. If the above steps failed to improve functionality, thena. Remove the vibration actuator insulation and steering wheel rubber coating where the
actuator is mounted. Refer to the images below.
b. Battery reset for 5 mins
c. Replace the vibration actuator
d. Perform step 7 and 8 again
e. Test drive and verify functionality

10. This image shows the rubber material
coating on the steering wheel removed
where the vibration actuator is mounted.

11. Image shows the vibration actuator with
the insulation removed.

Always connect a BMW-approved battery charger/power supply (SI B04 23 10) when
performing programming.

PARTS INFORMATION
Per Procedure step # 9 only:
Obtain and confirm the part numbers for your specific vehicle by entering the chassis number in either ETK
or AIR which takes into account specific equipment and/or options.

Note: 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.

Removing / replacing vibration actuator for LDW

Refer to AIR

Refer to AIR for the corresponding flat rate unit (FRU) allowances.
Work time labor operation code 61 00 006 is not considered a Main labor operation; however; it does
require individual punch times and an explanation on the repair order and in the claim comments
section.

During the same workshop visit, if a vehicle also requires another Technical Campaign or repair that
also includes programming and encoding the control units, the programming procedure may only be
invoiced one time.
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 IRAP recovery procedure (when applicable as
required)/repair work 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).
