2002 - 2005 L322? You cannot "upgrade" the column. The part number ranges between 8 different sets of numbers. They decided back then to make 8 different versions of the steering ECU and have them talk to cars based on part number. There is nothing to initialize or "synch" when installing because you CANNOT change the part number.
Don't let anyone tell you otherwise. Get 000162 to replace it. Unless you intend to frankenstein the 2 columns together, which is of course possible.
