    Speedo Sender Interchangability question

    Hi Guys

    Help needed with speedo, I have fitted part number 278 001 993 sender unit (05 and up) and it reads slow, very slow. I checked on line and the 04 models use part number 278 001 585
    This is fitted to a converson with components sourced seperatly, I beleive I have 05 componentry up but the instrument cluster may be 04.
    Is the speedo matched to the guage or the MPEM?

    Not your run of the mill question.

    Cheers

    If the ECU-MPEM is from a 04 ski you need the 585.Otherwise 993 will be used.If I remember correct,the 993 will not read speed with 04 electricals.
