Hi, I'm having trouble starting my 2006 Diesel CDI Fortwo. I suspect the starter as the lights come on, etc.. but only clicks and I hear a lot of noise, clunking type noise in the rear of the car when I try to start it. Perhaps the battery is a little low, but I don't know how to hook to the battery. I believe I just have to pull back the flooring on the passenger side and I'm going back to the manual to research, but if anyone has any suggestions or anything in the meantime. I am open to listening Thanks in advance for any guidance.
