Erroneous Brake Pad Replacement Message
MODEL
E90, E91, E92, E93 (3 Series) from start of production to 9/07
SITUATION
The Dynamic Stability Control module (DSC) calculates the brake pad replacement intervals based on
information from the front and rear axle brake pad wear sensors. When replacement of the front and or
rear brake pads is necessary, the DSC control module triggers an indicator lamp located in the vehicle's
instrument cluster. However, the brake pad indicator lamp may be illuminated although a replacement of
the brake pads is not necessary. Additionally, one or both of the following fault codes may be stored in
the DSC control module:
5DE0 Brake-pad wear: plausibility, front axle
5DE1 Brake-pad wear: plausibility, rear axle
CAUSE
DSC software error
PROCEDURE
1. Perform a short test with the GT-1.
2. If DSC has faults 5DE0 and or 5DE1, enter the test plan.
3. In the test plan, check the CBS data.
4. If the CBS data shows a value within the nominal range (100% or less), work through the entire
test plan.
5. If the CBS data shows an erroneous value such as 255%, the vehicle must be programmed.
6. Program the vehicle with the most recent Progman version (target data status E89X-07-09-518 or
later). Refer to SI B09 05 01 (Coding, Individualization, Programming), Procedure B.
Note that Progman will automatically reprogram all programmable control modules that do not have the
latest software.
