e65_reverseengineering's Introduction
Reverse engineering on PT-CAN and Local-CAN of BMW E65/E66
CAN-IDs in PT-CAN BMW E65 with MED 9.2.1
The information about the CAN messages and signals was taken from the original Bosch document that I found in a forum on the Internet. They were compared with my own BMW 760Li year of construction 09/2006 model year 2007. This car has a MED 9.2.1 installed, a further development of a MED 9.2 that was used with the E65 V8.
