I own a 325i e90 sport for the past 5 years. Just a month ago when I was driving home after work I could smell something burning from the front then a few meters my car started losing power up to a point where it stopped totally. When I put it in Gear 1 or reverse, the car wont move instead it will just rev high. Gears are not stuck or anything but the car wont move forward or reverse. Mileage is 164000 Please help. Ashley
