Which seat module controls bolsters/dynamic?
There seem to be at least 3 control modules on the front seat of my S600. Does anyone know which one controls the dynamic bolsters?

thanks in advance

Very helpful! Because I mistakenly thought that first pic meant I had to remove the entire seat! Do you know if this new module needs to be coded by the dealer?

Not according to WIS, plug & play.

Sorry to be slow here, but I don't understand this response. The part I linked too looks very different than the part that resides in the back of the seat (air hoses and what not). my car is a 432 (S600 came with the fully loaded seats).

As best I can tell, that part A221 900 37 01 I posted from eBay is not for my car, but rather 2010+

thanks

Thought you were asking if same CU is used for multicontour & dynamic as it pertains to your vehicle. As it concerns 3701 = dynamic feature CU not applicable to your seat/vehicle.
