Thread: Cold Star Problems 2012 2.7 Diesel Discovery 4

Hello from Snowy Mountains,

0 degrees C and again my Discovery 4 will not start easily. Takes maybe 10 times of cycling / pressing brake pedal and start button to get it to start and then shuddering for the first few seconds. My friend's same car parked beside has no issues and starts instantly. Battery is new. Is there a trick to getting the car to start in cold weather. I see "Cold Starting in Progress" and glow plug light goes out. What is the possible issue? Maybe a sensor? No issue in warmer temperatures. Car is serviced by Land Rover shop and goes well. Have owned car six years and this cold start problem seems to have appeared first time last year and now a bigger problem.

Many thanks

Same in Perth in recent days noticed a few extra revolutions on one super cold morning.

LR Time demonstrated that 50% of glow plugs can be kaput which in extreme cold climates is a critical thing to avoid long crank times that delay achieving correct oil pressure.

They don’t register a fault if they are not working but you can resistance test them on the engine I think.

Originals are best also.

Mine has originals so goodness knows how many still work but not cold enough here to worry.
