A168 gearbox
I am new to this site
I have just bought a 2003 A168 automatic with a gearbox fault.
I sent gearbox ecu to ecu testing & it came back beyond repair

I then bought a second hand ecu when fitted it now displays the F light on dash & wont change gear ?
does this ecu have to be programed to the car by MB or is there another problem with the ecu

any help much appreciated
Thanks
