Who at the dealership told you this? BMWs that have the old CAN/Diagnostic/I/K/M/P communication bus system (like the e53/e38/e39/e46)..DON'T have the "intelligent battery system" like the new BMWs with i-Drive and the new MOST communication bus (e65/e60/e90/e70/f01/f10/etc).

I'm not sure how many times we have to reply that there is no requirement (or way) to "register" a battery in an e53...again, because the intelligent battery system/sensor IS NOT used on the e53 X5.

Here's another example...just look up the battery cables for the e53 & e70 and note that the description for the e70's battery cable indicates IBS in the description of the negative battery cable (#1 in diagram below)...where as the negative battery cable for the e53 DOES NOT:

e70 neg battery cable (#1 in diagram below...has IBS on neg cable):

e53 neg battery cable (#10 in diagram IBS on cable):
