I agree that you probably have a ruptured EGR cooler. This would also mean that you have a clogged oil cooler and if you don't fix the problem soon then you are probably going to be replacing your head gaskets. :sad:
AGREED! Pull out your EGR valve and look down into the port...It will likely be caked with carbon but it should be dry. If you seen any moisture, then it's likely your EGR cooler is bad and that means the oil cooler is bad too. (You can also pull out one of your glow plugs...if coolant dumps out, you will have your answer.) If you keep driving it, it will hydrolock and leave you stranded! Consider an EGR delete kit to prevent this issue in the future.
