Avia_hole, on the G30/G31, the SZL (A83) is not a programmable module (no "smarts"), like what is found on other BMW's.

What does this mean? It means that it does not come up on the ECU tree as a module.....so it's merely an electrical pass through, like a connector, which makes it a little difficult to "find" in BMW's TIS.

I think you are asking about A83*4B, but if you can confirm the connector reference you are referring to in your original post, I can provide the front-to-rear pin assignments from TIS.
