Car might need LDM module.

edit. LDM needed only for 544.

Code it with 544 instead of 540

W 540 GESCHW_REG //GESCHWINDIGKEITSREGELUNG ueber Lenkstockhebel

W 544 D_GESCHW_REG //Dynamische Geschwindigkeitsregelung

544 is for 6cyl with brake function
540 4cyl without brake funktion

A 6cyl switch unit will work on a 4cyl
but a 4cyl doesnt work on a 6cyl

Your switch unit must have two steps when you push or pull it,

1 for 1 KMH steps the second for 10 KMH steps.

Sorry for my bad english ^^

544 was never an option for the E87.
Car still needs to be going to my workshop.

Hi,

i've similar problem: i've mounted 6cyl switch in my e87 and the cruise control works fine, but i coded it with 540. The only thing that i'm not able to do working is the set point visualization on the display. I tried with set TEMPOMAT FUNCTION on werte_02 but it wan't work.

Maybe i was wrong with the 450 code instead 544?
