    For those who might be able to help but don't immediately remember what N0202621 means, it is the turbo coolant return hose under the water manifold on the intake side of the engine. The hose is somewhat special because it has to run at more than the general coolant temp (87-90 C) because it is returning the coolant that has just gone through the very hot turbo. While OE would still be my recommendation, some people have tried a multilayer silicone hose with some success (not failed yet). Other folks have suggested that high temp hydraulic fluid hose might work. No comment.

      I replaced mine with a piece of off-the-shelf Samco hose, been on for 4-5years now and it's fine

        I bought a length of nomex silicon from Roose - not used it yet though!

          Can you recall what diameter hose you used?
