I am selling a used transmission control module for a Mercedes from 97-00 I believe this unit will work on w129/140/202/210. It was removed from a w210 320e, you will need to check the part number to verify that this is the correct part for your application, part # A 020 545 92 32 , 5WK33892. This part is in good working order. If you have any questions please feel free to ask.
