- .... (add your motivation if both mine were wrong)
The reason why the site is incorrect about the 2005 e53 w/N62 is
- ...nothing changed with either N62 engines regarding their vehicle electrical battery cables from their debut starting with the 9/93-up build date (which is the beginning of the 1994 model year & use of the N62 V8 engine)...so why would the 2005-up require "registering" whereas the 9/93-9/94 don't.
- ...the way that the CPU (the DME) knows how to alter the alternators output based on the condition of the battery is with a SENSOR...this sensor is called the IBS (intelligent battery sensor)...and the 2005-up e53s w/N62 engines DO NOT have an IBS on the negative battery cable...nor anywhere else in the vehicles engine electronics system...so there's no way for the DME to control/alter the output from the alternator because it receives no constant data as to any changes in the battery (other than the old fashioned way of the BATTERY WARNING LIGHT).
If further proof is needed to ease your mind as to if the e53 requires "registering"... item #10 in the diagram and link to the part nbr index below is the negative battery cable...you can see that there is
no IBS sensor designed into the cable...UNLIKE that of the e70 X5's negative battery cable (seen in the 2nd diagram below).
Hopefully this will help clarify any confusion owners of e53 X5's w/N62 engines may have...and those with I6 engines, too.
E53 Negative Battery Cable (#10 in diagram...no IBS illustrated in diagram, nor mentioned in the supplemental columns of the part nbr index at the link below)

E70 Negative Battery Cable w/IBS sensor (#1 in diagram below)...note that the IBS is mentioned in the supplemental columns in the link to the part nbr index below...as well as being illustrated in the diagram. And if you do a google search for this battery cable, you can visually see the sensor built into the negative battery cable.
