It could be one of several codes - you're missing the last few digits:

B1606 81 Battery charge status unit configuration fault: Not characterised
B1607 44 Fault in the memory of the battery charge status unit: Not characterised
B1607 45 Fault in the memory of the battery charge status unit: Not characterised

But in either case, there is no further info because the unit is faulty and not communicating with the BSI, hence uncharacterised fault.

Mechanic said he thinks wires maybe corroded or split behind unit rather than faulty unit. What do you think?

Also there were a few variants of these depending on engine / build date.

Ok, so yes it will need programming, as the unit needs to know the battery type and level. This should be set according to the correct type and battery for the vehicle. You'll need Diagbox to do this, run a global diagnostic and then look for the battery charge status unit on the list or the battery itself.

As we know this is a configuration fault, it hopefully may be the fact that it has not been configured and hence the message.

If you want to know the correct battery type you should have, you'll need to provide your VIN. Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

Yes, Enhanced Flooded Battery was factory-fitted so there may not even be an AGM option.

You didn't mention if the replacement unit was brand new or second hand. So if new and the correct part number, then it must be configured or you will get a configuration error and it won't know the type of battery you have for charging, nor provide the BSI with the data needed for fine tuning the energy management for the vehicle.

If a second hand unit was fitted, it will likely be configured for the previous vehicle....

So configuration should be checked and set correctly using Diagbox.
