Just bought another z4 e85 to replace my first z4.
Long story short previous owner put new battery in but didn't properly tighten positive terminal. After couple of joyful drives today zzz didn't want to start wasn't cranking straight away I thought to my self it must be battery terminal so I went done the positive and went back home. After few hours I went to start the car again and now it's not cranking it's dead and when I am plugging diagnostic tool itd blowing fuse for obd port. So I have a worrying suspicion that ecu is buggered. What would I need if that's the case ( z is automatic)
