Hello,
This website has been very to help me understand further the steps required for NCS Expert programming. Thanks for the contributions.
I have a question for the community.

I have 2009 E61 530d which had cloth semi-electric seats. A few months ago I managed to get hold of a set of what appear to be fully electric Sports Contour with memory seats with heated options. These came with the heated seat switches.

An Autoelectrician did a great job in wiring up the seats. The heated seats worked without any coding. When trying to programme the seats to the car, ISTA/P was taking many hours and we had to stop.

I have decided to have a go myself.
When using the BMW suite and the ICOM cable, INPA and ISTA/D recognised the new seat modules (SSFA and SSBF).
I am able to adjust the seats using INPA and ISTA/D but the seat switches are not being recognised.
I now wish to use NCS Expert to change the Vehicle Order to include the new seats.
From looking at VO code list, it seems that $457 is the code for "CONTOUR SEAT, FRONT, ELECTR WITH MEMORY".

Are there two scenarios here?

1. Use NCS Expert to add both SSFA and SSBF seat modules to the Vehicle Order? In which module should I add $457 ?

2. As the seat modules are programmed with the VIN from the previous car, should I rewrite these modules with the VIN from my car? If so, is this where I should be using WinKFP.

I shall be grateful if the community would advise.
I hope this situation also benefits other members of the forums.

Regards.
Imran

Check wiring diagram:

I did retrofit seats in E60 one time and i noticed that Switch clusters of seats are in some models not directly connected to the seat module.

The switch clusters are then connected with a K Line bus to the center control unit witch pas the commands further on the K CAN bus witch is connected to seat module.

Also seats have a hardwired link(Adress) for the commands to go to the correct seat

Coding was only necessary for seat occupation. because car old seat had SBE seat recognition sensor and new seats had OC3 seat recognition sensor.

Your electrician did not wire everything nedded...in addition to semielectric seat wires you need additional +12v, ground and kbus wire, also you need a additional ground wire to "code" passenger seat, otherwise both seats will move in the same time )
check wds, you have all thet you need there...

Thanks for your replies.
According the WDS, the auroelectrician did connect the +12v, kbus (to the seat switch module behind the the glovebox) and the additional ground wire that Zeronoo mentions.
He was talking about these connections at the time.
It's interesting that in INPA and ISTA/P, the seats can be adjusted in many directions, including headrests.
Would that not imply the wiring is connect?
Can the seat switch module be interrogated and enable communication with the switches?
I was looking at the VO in NCSExpert today and was thinking that the seat modules need to be added.
Thanks again for your advice.

Seats should move without coding as well. But the fact that ista can move the seats does not mean everything is done correctlky. Because ISTA drives the seat directly from the SMFA (seat module driver) and the SMBF (passenger). But the normal way is:

Switch on seat ---> switch cluster centre console (SZM) ----> seat module.

But on the LCI models you also need an additional module, which is called PowerElectronics. This controls the power to the seats. Without that, seats wont work properly.

I did a retrofit from sport seats to comfort seats in a e70 and i had the same problem. With inpa i can move the seats but with buttons nothing happen. I did search in wiring diagram and notice that the seat buttons need also power because they are not supplied from the seatmodule.

That's interesting.
I'll look further into this and keep you informed.
Thank you for your advice.

Do I need to register with Mega to see the file or can I get a copy of the text file ?

In the WDS wiring diagram, I can see reference to :
Seats (5 series E60/E61)
Control Switch (seat)
Switch, driver's seat adjustment (SMFA Seat module, driver)

It looks as if on Connector X603, Pin 1 needs power and Pin 3 needs the K_BUS (LIN BUS on LCI model?).

I'll check the connectivity in the car.

You don't need to register with Mega. Just click on the .txt file and follow the link and download the 3 PDFs.

On X603 (connector on switch on drivers seat)
Pin 1 Ground
Pin 2 connects to Fuse 74 in the fuse box so should have power
Pin 3 has the K-bus signal
Pin 4 connects to pin 43 on your light module.

What signal is the link to the Light module providing ?
