I heard that vw is using this in their newish 2.0l tdi. Anyway its a very interesting technology.

This egr takes post dpf exhaust gasses and routes into the engine pre turbo. The exhaust goes through the normal intake track turbo, intercooler, and then into the engine.

The turbo charger has to be designed to handle the the crap in the exhaust but other than that you don't have issues with tons of soot clogging your egr system, and the egr being super hot compared to your normal intake air. It also seems to work better and has lower emissions vs the common high pressure system. I'm sure it also reduces your coolant temperature comparatively speaking.

The only thing i can see is decreased turbo life being a negative.

What is everyone's thoughts?
