If the hose is leaking, more than likely the egr cooler is cooked also. A bandaid approach will usually come back to bite you. I would recommend flushing the cooling system first, then replacing both the egr cooler and engine oil cooler. Another option is an egr cooler delete and oil cooler, but that is up to you and your comfort range with state and federal laws. But yes, turbo and turbo pedistal need to come off, intake manifold needs to come off to do it right. Once the turbo and pedistal is off, you have a somewhat better view of the hose. I have heard of some being able to repl the hose with just these items off, but it will still take a magic trick to get it in correctly. Here's the issue, that blue hose is coming out of the engine oil cooler and into the egr cooler. The engine oil coolers clog up then starve the egr cooler of coolant, which then causes the egr cooler and hose to leak from high temperature overloading.
