SITUATION
The calculated remaining service life for the brake pads (front and/or rear axle) from the CBS data
does not match the actual brake pad thickness. The customer notices implausible remaining
distances (too high or too low) on the front and/or the rear axle brake system.
Note: E9x vehicles with xDrive are not affected by this bulletin.
CAUSE
Software calculation in the brake pad wear model
CORRECTION
Run vehicle diagnostics with ISTA/D and work through the corresponding test modules.
Note: When the ISTA system message displays: Battery voltage only “XX.XX” V. Please connect

charger. Please note the displayed battery voltage reading in the repair order comments section.
If the brake pad thickness is less than 4.0 mm (and only if it is), the brakes on the axle concerned
(front or rear) must be replaced before working through the measure.
Provided there are no faults found (this must be resolved first), update the vehicle software using
ISTA/P 2.50.0 or a more recent version. Programming must be started under the conversion menu
item “Brake pad correction CBS conversion.”
After programming, the vehicle CBS data must be corrected as follows:
Using ISTA, perform vehicle CBS data correction
In the diagnostic menu item “Front/rear brake”, select “Reset forecast to 50,000km” and then reset
the forecast distance.
Check the remaining brake pad thickness using special tool 34 1 260.
In the diagnostic menu item “Front/rear brake”, select “Set availability, enter the brake pad
thickness” and enter the pad thickness measured in mm.
Note: If the service counter increases after entering the actual brake pad thickness, the brake pad
thickness must be entered once again. The service counter is now reset to the original value.

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.
If a control module 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.
Other Repairs
If performing other ISTA diagnostics and related test plans results with eligible and covered work,
claim this work with the applicable defect code and labor operations listed in KSD2.
Brake Pad Replacement (less than 4.0 mm of brake pad material remaining)
Covered under the terms of the BMW Maintenance Program only.
When brake pad replacement is required (front and/or rear), when eligible, claim the brake pad
replacement under the BMW Maintenance Program (defect codes and labor operations including
the Standard Scope and performing a CBS reset).
