I made a video on how to remove and install a parking brake module on an E70.

This video shows you had to replace the module with leaving the bowden cables on the car and removing it with the cables attached to the module.

Hopefully this helps a few people out. I bought a re-manufactured module off Ebay for $365 and fixed my problem. They use the later updated module made after 2011. The video shows you where I bought mine.
