Interesting info. How common are those gasoline 2.4L sixes there? Wonder what they call them by -- "gasser D24" doesn't sound very official... If it was a Volvo motor they probably would have called it a "B24", but I know VW generally uses a different, and less logical, naming convention.
I remember reading somewhere that Volvo was involved in the engineering for the adaptation of turbocharging to the D24. If that is true, then VW got a lot of use out of Volvo's contribution in all those TD LT's. Have you ever heard anything about that part of the relationship? I'll try to find where I read that claim -- think it was in a Volvo official publication somewhere.
