After driving this car since Nov 2014 I have become accustomed to the glow plug light not coming on when starting the car or coming on for a flicker
During the recent cold weather at -4,-5 degrees it did come on briefly for a few seconds
However yesterday the outside temp on the car display said 12 degrees and today 6 degrees and the light came on for several seconds and this was for a 2nd trip both times??
Just puzzled why its comes on and stays on for longer in mildish weather but not cold weather??
