just recently my mates MY00 has started to whine from behind/under teh dash. now its related to the speed level and gets pretty loud above 100km/h.
it hasnt started for any apparent reason (only he has started driving on the highway a fair bit) never launches the car or done anything different for the last 50,000km. Still on orginal clutch which does slip occasionally.
Box still feels the same and moves the same but has the whine.
Is this normal?? any fixes?? is his box rooted??
