Same thing happened to me two weeks ago. Lost servo and cooling at 170km/h in a left turn :-(
I drive a GTV V6 Turbo. Had the additional problem that i could not stop the car right where it happened, had to drive an additional 2 miles. The motor did alright though, even though it was heating up pretty quickly.
The repairs were done on guarantee so there was no cost involved, still having my gtv sit idle for a week hurts...
