W212 Battery Sensor B95

[Biohazard_SVK]

Has anyone solved the problem with the B95 battery sensor? Diagnostics says: communication with the battery sensor has a malfunction. Error code U113E00. Should I replace it with a new one or can I use one from another car?

First of all check the wiring to this sensor 2 cables. Often it was damaged and shows this error code. If everything is ok, replace it. A new one is not needed, it is just a sensor without coding etc. You can buy a used one.

Okay, got it. The cables are fine, I'll replace the sensor.

Check the battery voltage with DVOM on the main battery and compare the values with the battery voltage indicated in B95 via Xentry. If the battery voltage differs from the actual values shown by DVOM, then B95 should be replaced. If communication with B95 cannot be established via Xentry, the LIN line from B95 to FSAM should be checked and excluded, if all is OK, replace B95.
