TECHNICAL SERVICE BULLETIN

Reference Number(s): SI B34 03 13, Date of Issue: May, 2014

BMW:	E82, E88, E90, E91, E92, E93; Produced from 3/2010 through 6/2013, F25, F30, F31; Produced from 7/2011 through 6/2013

Superceded Bulletin(s): SI 34 03 13, Date of Issue: November, 2013

SERVICE INFORMATION

This Service Information bulletin supersedes SI 34 03 13 dated November 2013.

SUBJECT

Incorrect Remaining Service Life from CBS Data for Brake pads

SITUATION

The yellow "Service Due" warning message lights up in the instrument cluster, even though the brake pad thickness is more than 4.2mm (above the thickness at which the pad sensor intervenes). 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.

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 there are no faults found (this must be resolved first), update the vehicle software using ISTA/P 2.50.2 or a more recent version.

E82, E88, E90, E91, E92, E93 - New Integration Level: E89-13-07-503
F25 - New Integration Level: F025-13-07-503
F30, F31 - New Integration Level: F020-13-07-503

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.

WARRANTY INFORMATION

Covered under the terms of the BMW New Vehicle/SAV Limited Warranty or the BMW Certified Pre-Owned Program.
