Subject: Your wife's E39 battery is a 100% compatible perfect swap... Author: Brian (moderator) : member since January, 2005 : 8586 posts Posted on: 2009-01-14 16:46:24

In fact, if you really get brave, the general module and light control module are also swappable between cars for testing purposes. The E38 and E9 share many parts.

Installation of the GM and LKM are both very easy. However, both require dealer coding to properly configure them to the car. Plus, you do not want to drive a car with an uncoded (or swapped-in) LKM, because that will cause the mileage tamper dot to illuminate on the instrument cluster.
