I'm helping a friend with his 2013 335 f30 swap out his seats. He bought a set of sports seats for his car. Battery was disconnected from the car the whole time and when the car starts we're getting the srs warning.

I cleared out the codes using the transmitter function in E-SYS and still showing up. I then switched to ISTA and did the following:

Service Function->Body->Safety functions -> seat fore/aft adjustment calibration

When doing this I received an error that stated it couldn't standardize the seat because the control unit is not encoded. I couldn't find out how to do this within ISTA, so I verified in E-SYS that his vo had the 459 and 481 codes. I then coded the car like I needed to do as well.

I went back to ISTA and still receiving the same error and the SRS light is still on.

Anyone have any clues that could help us encode the seat?

I did a sport seat swap into a base and I swapped the modules under the seats and it took me a few tried to get the codes to clear with a scan tool.

Do we have to swap the module? I'm trying to avoid that.

I am just saying that’s what I did and it helped fix the light issue. It’s pretty easy to do if you have them.

He still has his old seats we could do that if needed

You can always switch them back. I did read a few other people that had to swap them as well.

That's the easiest way.

Yes. Swap the modules. They are actually quite easy to swap. I had to do the same when I swapped in M3 seats.

Hey
I have a 2015 BMW 335i xdrive base model ( base model seats heated+ particial electric+ memory). I picked up m sport seats from a 340i (lumbar support+ side bolster+ heated+ memory). All I did was swapping the seats and belt tensioners and also my driver seat gray box Module from my car , everything works EXCEPT SIDE BOLSTERS AND LUMBER SUPPORT. It really sucks because I was so excited once the seat moved automatically and heating worked. Anyone had the same situation or know what do I need to do
