Recently I’m experiencing a problem with my 2011 c class, try to started after glow plug light goes off car will take 5-6 seconds of cranking than will start with a cloud of white smoke.
If i put ignition for 5 seconds in second position car will start just fine.
I have replaced fuel pump from the tank and glow plug module didn’t improve. Has someone had this problem before ?
