ML270 CDI Does'nt Start
 

Hi All,

New Here, hope someone can assist me,

I have a 2000 W163 ML270CDI,
Having a starting issue, what i have noticed is when key is turrned on, all IC lights come on , as long as GLOW PLUG indicator light does'nt car will not start, does'nt even crank, have to turn key on / off repeatedly until GLOW PLUG light comes on them she fires up

MB dealer diagnostic does'nt pick up any fault, checked starter cabling, initially I thought it had something to do with ambient temperature but realised can do it either at 4 degrees C or at 30 degress C

Would really appreciate any feedback
