greetings,

my ride is a 2001 clk 430 which has the 2.82 diff and i want a bit of more performance from 0-100km, all my bimmer friends simply swap the diff and all is good... i found out after research that i need the EGS or TCU for me to make it work, making a long story short i got a deal on a 3.07 diff and its EGS from a 1998 CLK 320, what exactly should i do after installing the diff? simply remove the current egs and put in the new one? or do i need to have a scanner / coder tool? any help will really help me out

thanks in advance
