As everything on my 300Tdi D1 works, bar the cruise control, I am on a mission to fix it!
Replaced all the spilt pipes but still no joy, I have found the little vacuum pump under where the jack goes (dumb place to put it) and re-connected the pipe as it had come off. Does anyone know if this little pump should run as soon as you press the master cruise switch on the dash (mine doesn't) or should it only run when the cruise 'set' switch is pressed above 28mph please?
Trying to establish if this pump is goosed and in need of replacing.
TIA
