My board was soaked in glycol, the socket was damaged, and the connections fell off. Does this LDU board have an immobilizer?

Try swapping the batteries and see if you still get errors in the BMS.
I don't think the BMS will need to be programmed.

Hi,
I have a B250E that I filled with coolant. The engine electronics were also flooded. The windings are new and have been checked. Now I have a BMS error: U1C3BF1 - "High Voltage Battery Module Voltage" sensor malfunction.
Did you fix the problem?
