I don't agree with letting your turbo cool down by idling with a diesel when getting off the highway. Up to 70 mph my turbo is not even pushing 5 psi. Just the time you spend getting off the highway till you can actually park is plenty of time for the turbo to cool down.
That being said, I would not pulse and glide with EOC in my TDI on a regular basis. I don't like the fact of requesting max boost for ~10 secs and then immediately have the oil sit in the turbo. I do however EOC if I've been driving lightly in the previous minute or so.
