How do I jump start a bmw 650i. I do not know where is the battery located


BMW batteries are usually under the rear seat, however there are special terminals under the hood which can also be used. It really makes little sense to work on your own car without buying a cheap shop manual, especially a BMW.

BMW e46 won't start because of the alarm.


Hi, if the car stay for long time the computer box lost memory. Now is not reading the key. You need to program your key again by BMW manufacturer. Also on bmw the alarm is connected to computer box too.

Bmw z3 1999 will not crank


The problem sounds like the battery has run down. Even though the ignition is off, things like clocks and the radio draw small amounts of power to retain their settings, and the instrument cluster doesn't draw as much power as the starter. It usually takes about a month or so to drain the battery. Try jump starting the car, or put it on a battery charger for a while.

My 2000 300m has been sitting for 7 months without being started and the battery went dead during this time. it was running fine prior to sitting. I tried to jump start it and it would not start, I saw...


There has to be a code store in the computer that will tell you what might be wrong. the code is the place to start. My 99 sat for a year, and after recharging the battery and getting it started the only code I could get though, was the dead battery or disconnected battery code- but the point is, it started. Check for mouse-eaten wires at the cam sensor and the Crank Sensor. Hey- it could happen...

Car has been sitting 5 months without being started


the battery may be shorted out. do you have a meter to check a batteries condition? if not take the battery into the parts store and they can tell you if it has a dead short in it which means the plates inside the battery have sulphated together and wont allow current to pass through them. lead acid batteries are real bad about this if they go completly dead even if they are newer batteries.

When i start my lucida it cranks once ,then clicks and clicks and


go ahead and jump it. your battery is dead or you have a bad connection with the battery cables. try jump starting it or at least hooking up a battery charger over night. (the engine size of the vehicle wont determin if it will be able to jump start the other vehicle.)

My z3 starting problem


i would say its a dead (flat) battery. if its more than 4 or 5 years old, it might be time to replace it.

try jumping it with another vehicle. if it jump starts, then replace the battery.

if its a newer battery (less than 4 years old), then something is draining the battery or the alternator is not recharging it.
