I have changed the primary battery on my W211 05, however, the display still indicates a battery visit workshop. Do you have any suggestions? Require brake bleeding

The term 'battery visit workshop' often indicates a problem with the alternator or other elements of the battery management and charging circuitry.

Prior to rejecting the battery, it is necessary to do independent testing, unless it is an outdated battery that you intended to replace anyway.

Thank you. Upon testing the operating voltage using Icarsoft v3MB, it was found to be 13.88 volts.

This is equipped with a fresh battery.

Have you conducted a thorough vehicle inspection or recharged the battery?

Merely being new does not imply that it is completely charged.

Verify the voltage of the auxiliary battery located under the pollen filter.
This is often overlooked.

My reading is around 14.7.

All of my merchandise has.

Presumably, this is the case, and it may be SBC brakes.

It has been determined that the auxiliary battery, as the primary battery failed to charge, necessitated the replacement of both batteries. The following inquiries pertain to brake bleeding.
