We also had problems with dad's TGV. Did great in the donor Disco on the 2000 mile test drive with only having 40.000 miles on the engine. After swapping it to the Ninety it dit great for 5000 miles also, until it died in just a normal 50 miles an hour drive on the highway. No signs of failing before, coolant temp and oil temp and pressure all ok. Brought the car to Prins Maasdijk, who discovered the last piston cracked in 2 pieces, probably due to a failing injector.
No warranty as third owner of the engine and no paperwork with it. But they did a pretty nice deal on a new TGV engine after leaving the failed one there.
Hope my own TGV, also out of a Disco donor, doesn't have that kind of problems in my 110. Is your car still in Holland? Might be an option to leave the car at Prins for them to check it out.
Good luck sorting out!
