My ASC light recently went on. No matter what i did it still stayed on. Well anyway i have a few BMWs so i purchased a Snap On scanner and scanned the codes. it came up as code 39. i cant exactly remember the name it gave me but ill scan it again and post it up. but in the meantime if anybody knows what might be wrong please let me know.

it said "39 pre-throttle vavle servo motor"
