Good evening JGtazzie,You should be able to use your mechanical key to unlock the trunk.

blue or blue/gray smoke is a sign that engine is burning engine oil. keep an eye on oil level and if engine is getting hot or over-heated this will not help your situation.

on the passenger sidestrut tower, ther is a small plastic cap door with a "+" sign that is the battery positive thats where it should be....

It could well be a voltage problem. An occasional dip or spike in voltage can cause all kinds of problems with BMW electrical systems.
I would get a voltmeter and try monitoring the voltage at my lighter outlet while I drove around for a day or two, You should make sure that the battery terminals are clean, and you should clean the main grounds at the battery and under the hood (hard to find) and check the ground strap that grounds the engine to the body. The ground strap is likely is next to an engine mount.

Have an OBII scan done. (fault scan) Your description can describe many things and a scan will narrow it down to the exact faults. It's easier & cheaper than throwing parts at it. Trust me, I used to work for BMW NA

Yes big time and thats the amount of petrol this vehicle uses ,but mechanicaly no problem at all in fact a nice car but at just under 2 dollars a LITRE for fuel ---- it has to be a diesel version for me

hello doc....

The emergency brake is mechanical not electrical. There is no fuse for the emergency brake. It is most likely that the brake cable leading to the rear brakes is stuck. This is quite common in vehicles with automatic transmissions because the e-brake (parking brake) is not used very often. As a result the cables get rusty and stick. It is also possible that the cable needs to be adjusted; but it is more likely that it will need to be replaced due to 7 years of exposure to road dirt, water, salt, etc. etc. etc.

You may be able to release it by putting the car in drive and then into reverse to put a little pressure on the cable. If it does release for you, still have it checked as it will lock up again. Joe

Thanks for choosing Fixya!

Check for power at terminals on back of speakers and make sure the plugs wern't loose. if there is power there and they wern't loose then replace the speakers.

Check with your local BMW dealer. If there is supposed to be more than one key for your vehicle, they can not only tell you, but they can also cut a new key by looking up your key codes using the VIN on your car. If there is supposed to be only one key for your vehicle, they can assist you in getting any malfunctioning key cylinders repaired or replaced.

The parking brake cable is probably frozen by dirt or corrosion (too much friction for the brake return spring to overcome). Try injecting Liquid Wrench or a spray lubricant into the cable housing(s) underneath the car, then pulling on the cable by hand. If you get it loose, clean up the part of the cable that goes into the housing, or any part that slides on another, and coat with a thin film of grease. Engage and disengage the parking brake several times to make sure it works smoothly.

If you can't get the cable to work freely, you may have to replace it.
