2001 BMW 525I User Comment / Complaint

I have 2001 bmw 525i. i went to dealer service so many times to fix my problem concern. they won't fix it and said that "no customers complaint duplicated" all the times. after done my first 15000 miles service at dealer, "eml" lights came up and i sent my car to dealer immidiately. they changed "trottle body" because they said, it's burned. after that repair, my car has alignment, trottle, accelation and transmission problems. also they replace the fan by recall. now my car conditions are poor. i press the gas peddal for accelation, rpm's going high and big idle sound i can hear. and, over 80 degree temp. big big idles. also decelation is not working. speed won't reduce until i braked. car riding quality's getting poor and poor. suspension can't absorb roads bumps. at the same time, i hear so many clicking noise from door frames. it feels like where i drive at off-road. also, i checked alignment by machine. it was really off-set. the camber, cast and toe was bad. they perform the alignment job. but still poor. i suffer with those problems about a year already. recently i felt that steering wheel is shaking and i felt a vibration from from floor of driver side. also badly, front low head beam is too dim and not blighter than before. it cause, hard to drive at night. i think, my car has engine, transmission, trottle and some junction problem from engine thru axle. today i catch another thing. when i turn on the engine, i heard ruffle sound from bottom of engine room and big engine noise. please review my compliant and what really should do?
