Well I have an FBH, which is nice! Everyone can significantly decrease engine warm up time just by ensuring the heater contols are set to full cold during warm up. You can feel the engine power diminish as you twist the heater control towards hot when the engine is very cold and warming up.

After reading these posts I think that most diesel owners complaining of slow warm up have a broken themostat. The thermostat is not closing properly, I have changed a thermostat before that looked ok to me but the replacement completely fixed a warm up problem that that car had.

If you have a water cooled EGR then it enables a quick warm up by using super hot exhaust temperatures to warm up the cooling water. If you remove the EGR then you get a cooler running engine.

What about fooling the EGR into opening after start up to enable super quick warm up times? Probably a bad idea, anyone tried it?
