Wiper motor coding

[carmel120]

Hi I had a problem on my d3 the wiper motor has packed in the letter at the end of mine was B and then I have changed it to another this one has the letter C at the end and now I have lost the after wipe fuction when you use the washers when the headlights are on it used to do a final sweep to clean the windscreen after the headlights where washed,so is there coding or settings in the mmi to bring that function back.

cheers trev
