Most BMW's have the battery under the back seat (for better 50/50 weight distribution) and a "hot" point under the hood/bonnet. The "hot" point is protected by a one inch square of plastic clearly marked with a red "plus" symbol. This is the positive post. Complete the circuit by attaching the negative clamp to the car frame. if it is a standard shift, put the car in second, roll it down a hill or get buddies to roll it 5mph or so, and drop the clutch. imediately after you drop the cluth, deploy it again so the car wont stall on you, Ive had a similar prob cold starting my 87 535i, so i think you got the idea now
