On top of that, the trunk still wouldn't close consistently. When I picked the vehicle back up a week later, the rear view camera no longer worked, and the AUX cord was no longer a selectable option through iDrive system. They suggested I do an update on the FRM unit, which eventually bricked it, and then had to be replaced with a new one. This all started when I took my 2008 X5 4.8i to a local BMW specialist as (among a few other things) the trunk hatch was having issues completely closing (would get to the point of soft close, and bounce open). I have an e60 535d CCC unit in my car & have gone through this process so I'm familiar with it.I am sure this has been covered, but after struggling to get good search results, wanted to check to see if I could get some solid info. Main dealer BMW software cannot code used modules, they can only do new stuff. Autologic should be able to do that but NCS Expert can definitely do that. You need to code 5 modules in order to have the CCC working completely: Even without coding it should power up & some functions should work, others not. The e60 M5 CCC is compatible ith your car once it has been coded to your car. If you put a higher rated battery in to the car (or a lead acid battery instead of an AGM battery for example) again this will not charge properly, during the 'registerng the battery' process you also indicate the Ah rating & type AGM/LA battery. The battery will not be charged correctly as registering the battery tells the car to change the charging cycle. If you don't register it there are 2 potential issues: 1. Secondly you cannot replace the battery in these cars without registering it. Jump starting is bound to send surges of current about the place.

There's a complex electronic set up in these cars (& indeed most modern cars). First off all the jump starting is probably what killed your CCC.
