Hello!

I'm working on retrofitting electric seats to my X3 G01. The new driver seat has memory functions, with Seat Module present. Passenger is without module.

I have Wired the new power lines to the fuse panel near the BDC and the passenger seat is up and running.

But from the driver's side I have the K_CAN2_H and K_CAN2_L going to a R2a Can Terminator, that my car is missing.

I assume that I only have the Tailgate module that is linked directly to the BDC.

So I need to order a can terminator. But the list is big... Any clues on the right one?


Thank you!

Thank you!

You already have a resistor. You already have a roof function center too. So you'd just need to add the pins to the terminating resistor and then perform whatever other coding necessary to make the seat modules work.

freshxdough, thank you for taking the time to answer.

I was looking for the R2a CAN terminator, but it's not present where it should be.
Also, on the BDC diagram, there is a variant where R2a it's missing. I have attached part of the diagram, pins 49 and 50 from BDC module 8.

Could be that I have a low Roof Module with no CAN lines?
I will open it up to see what connectors are present.

Long story short, I got the 5x 120ohm CAN terminator. The driver seat powered up as soon as I connected the Can lines. After coding, memory functions are working too.

hello victormro, i'm going to replace manual seats to electric with memory on my G20, can you please share your experience on how to properly wire it?
