By warm it up are you talking about cold idling? That's very hard on diesel engines, they prefer to be started and let idle for a 3-5 minutes max and driven. 30 seconds and go is what mine gets.

P0489 Exhaust Gas Recirculation Control Circuit Low
P2262 Turbo Boost Pressure Not Detected – Mechanical
P0087 Fuel Rail/System Pressure – Too Low
P1011 Fuel Pump Delivery Pressure Too Low



How cold was is? Could your fuel have gelled?

Can you clear the codes at a local auto part store and see what comes back?

Thanks John..with temps zero and below and ice and snow on windshield I am forced to let it warm longer then 3 minutes...tried to clear codes with U-scan but ck engine light is still on..put diesel 911 and drove the recommended 20+ miles seems okay now but still have ck engine light on...

Do you have a block heater and a winter front? I would do what you can to minimize cold idling.

How often do you use the exhaust brake?

After several full run cycles without issue the codes will clear themselves.

Are all the codes still showing?

Also, use the high idle feature with the cruise control. If it is not activated, have the dealer activate it.

I second this, use the high idle and if fitted the engine brake to warm up.
If both is not available set the Automatic on "D" - Ebrake on!!
