Hi, maybe someone can help. Few months ago I upgraded my car's software in the dealers service, and after that my car's electric front drivers seat adjusting unit stoped working. My dealer checked the unit, and said that the unit in my car is from a newer model, but they couldn't explain why it worked before the upgrade.
My car is e60 2003' december, the unit in my car is from 2005' model.
Maybe someone knows how to make the same unit to work with my car? Or is there a way to move electric seat little bit to rear without unit?

I will apriciate any help. Maybe someone has "Switch seat adjusting front left" for sale?
