Mercedes-Benz vehicles route major wiring harnesses through the interior floors and trunk spaces. A common point of failure is the CAN bus voltage distributor comb, often located beneath the front passenger carpet or inside the side panels of the trunk. If a vehicle develops a blocked sunroof drain or a faulty windshield weather strip, water pools in the footwell, causing rapid corrosion of these vital communication blocks. 3. Low Auxiliary Battery Voltage
This specific Body (B) DTC (Diagnostic Trouble Code) reads natively in German diagnostic systems as "Клавиша 'Фавориты' заедает. Изменение сигнала отсутствует" . Translated, this means the "Favorites button is jammed; signal change is missing." This issue commonly disrupts the user experience across modern Mercedes-Benz vehicle architectures—such as the W213 E-Class, C238 E-Class Coupe, and W205/W206 C-Class—which rely heavily on the central console touchpad interface. Understanding Code B1E9E2A
If this code appears, a methodical approach is recommended to resolve the underlying issue.

Code implies that the computer (SAM module) sent a signal to adjust the left headlight but received an incorrect signal back from the motor or detected an electrical fault in the wiring.
Inside the steering wheel or console module, the button contacts can become worn or oxidized. This can cause a "noisy" signal or a constant short, which the ECU interprets as a stuck switch rather than a clean on-off signal. mercedesbenz b1e9e2a

While the exact string is rare, identical hex fragment errors occur in these chassis:
Does the button when you press it, or does it click normally? Translated, this means the "Favorites button is jammed;
Numbers indicate the specific subsystem experiencing a fault. In Mercedes electronics, these sequences typically target specific voltage drops, sensor values, or localized open circuits.
Do use water or standard household cleaners, which can short out the center console electronics. Turn off the ignition completely.
One specific code that frequently appears during vehicle electronic scans of models like the W213 E-Class or W205/W206 C-Class is . What Does DTC B1E9E2A Mean? The exact manufacturer translation for this code is: or localized open circuits.
