The BCM will need coding, Ideally from your old one...

 

But you could go through the systems and check what you do and dont have etc, but you will need VCDS or similar to do this.

Maybe consider contacting BBA Reman to see if or what price to repair your original one.

 

First VW Group link I found on their website:-    VW Passat BCM | Body Control Module | Volkswagen | Online catalogue | BBA Reman (bba-reman.com)

Saga update......

 

Invested in VCDS - paid dividends!

BCM - codes copied across - central locking etc all working.

 

Fault codes 625 and 993 showing.

 

TPMS - reset to factory defaults.

Steering Angle Sensor mechanical malfunction - reset to factory defaults, after double checking angles and completing steering wheel turning either way twice routine.

 

No codes showing on VCDS and no warning lights.

 

Decent test run later to ensure all is hopefully good!
