    Has anyone fitted a 641 servotronic module from an S4 into a b7 3.0tdi (640 stock) or does anyone know the difference between the two?

    Reason for asking is that I need to replace my 640 but would prefer slightly heavier steering.

    Checked all over the web and can't find any info on how it might alter the steering characteristics.
