well i did work at the volvo dealer for 3years. i don't work there anymore. your throttle is a fly by wire. you will need a new throttle from the dealer and the programing. a used throttle will not work. it is programed once at the dealer or sweeden for one car, never be used on another till sweeds get it back and do there master programing. there was a warranty but it is gone after 10years and 200,000 miles.
