E70 Front Seats, will they fit E53?

[Qsilver7]

This would. be interesting to see how it's done...especially since the e70 has a totally different communication bus system vs the older generation e53. The e53 seat module (PM-SM) is designed to communicates over the P bus & K bus. (See topology charts below)

We either have the Kombi bus. (identified by the low cluster)....or the I/K/M/P/Can?Dianostic bus (identified by the high cluster). The newer generation e70 has a more complex communication bus with its LIN, MOST, Byteflight, BSD, etc.

Will some type of intermediary component be required to get the seat control modules to communicate over a different type of communication bus because they are expecting to send/receive differently? I know some really clever owners have worked on and gotten the new style nav screens to work in older gen BMWs...so curious if this will be required with other components like the seats.

Example of new gen BMW communication bus (aka the ones that have iDrive)..the driver's seat control module (SMFA) communicates over the K-CAN S bus....see chart below. And for in depth details about the e70 X5 seats and how the various commands for them to function are carried out....click this link for a BMW PDF about the e70 seats: http://www.bmwmotorsports.org/pdf/e7...70%20Seats.pdf
