Cold Starting Advice
I've read many threads on this issue and had a quick look but couldn't find exactly what I wanted!
I have an 05 plate diesel auto with 95k on the clock. I suspect the heaters/glow plugs aren't functioning anymore and I was looking at a -6 Degrees Celsius this morning. I usually park the car tight in front of the kitchen window on nights like this. The AGA is constantly on and helps to raise the temp a few degrees, which makes all the difference. Not this morning.
I let the glow plugs (or what's left of them) warm up until the light went off. Turned off the ignition and did it again. On the third time I tried to fire it up and it just grumbled. Fourth and fifth time similar result. In a blind panic I tried the sixth time, pumping the accelerator and it coughed into action.
Is that the usual/best procedure? I can't remember exactly. Should I pump the accelerator, place my foot on it or leave it alone?
Changing the glow plugs is a monumental job IIRC. DOn't htink I'll be doing that. I can remember a while ago someone selling a kind of heater that you started 20 minutes or so before going out in the car. Anything else I can try? Would a hot air blower for 5 minutes make a difference for example? Blanket on the engine? Anything else?

I think the FBH will only cut in once engine is running, then continue if shut down if coolant isn't hot enough.

I thought that the glowplugs just failed given the age of the car?
Nope, some early D3s still have 6 good plugs.
The note above about the dash light not being representative of glow plug activity is correct. A longer pause, even after the light has gone off, will provide more heating. But as said, it isn't always the glow plugs so best to find out what the real problem is and if it just happens to be the glow plugs then get them changed as they are not optional items.

Much as FBH's and remote options for prestart running of them are great additions to aid starting a cold engine by warming up the water jacket, they aren't really a replacement for working glow plugs, they don't get the same level of heat into the combustion chamber Altox GSM FBH controller thread

If I use the FBH on mine, the glowplug light pops on for millisecs as a check then straight off. Dave

Once the ignition is on, doesn't the FBH kick in after a min or two anyway when its below 5DegC? Would you able to leave it this state unattended for 15+ mins?
Engine needs to be running for FBH to kick into automatic mode.
The FBH can be remotely operated as a park heater incorporating a 1533 timer for about £100.
Might be wise to do that mod before throwing big money at injectors or risk the potential pitfalls of glow plug removal.
Chances are it will improve cold starting dramatically as it has for countless others.Mods:
