BMW Electrical Problems: How to Solve Them Easy!
Stop Worrying, Anything Can Be Fixed!
Having car problems can be very stressful. Newer cars have increased comfort by incorporating more and more electrical parts (motors, wires...you name it). These parts of course will fail in time and it could seem like the end of the world but don`t worry, it`s not!
First things to check:
Most electrical problems can be easily fixed by checking the following:
- The fuse box
- The wiring in the the trunk that is attached to the battery
BMW Fuse Box Location
Most BMWs have the fuse box located in the glove box compartment. Older BMWs have it in the trunk near the battery so check out both these locations.
Check for bad fuses by taking them out one by one
A bad fuse is most of the time the cause of electrical problems so start with this step before taking your car apart trying to find the bad wire or contact.
BMW won`t start electrical problem FIX
Have your car`s battery tested
A discharged battery won`t let you start your car in cold weather, a very discharged battery won`t let you start your car even in warm weather.
Battery Voltage and State of Charge:
12.66v . . . . . . . . . . 100%
12.45v . . . . . . . . . . 75%
12.24v . . . . . . . . . . 50%
12.06v . . . . . . . . . . 25%
11.89v . . . . . . . . . . 0%
Many shops will test your car`s battery for free. Please keep in mind that a discharged battery doesn`t need replacing most of the time. The problem is with short trips in the city traffic you alternator won`t be able to charge your battery enough and it`s just a matter of time until it starts making problems.
BMW Steering Wheel Lock (ELV)
The "steering wheel lock" error pops up when the battery is low and usually in cold weather. The bad thing is that after this error pops up you will have a limited number of times to start your car after which the Start button will be useless. It`s not a problem with the steering wheel column, but due to the fact that the mechanism didn`t go all the way back (low battery) it will store that error which cannot be reset from the dashboard.
FIX: Get yourself a BMW K+DCAN cable and diagnostic software to reset your ELV lock.
The software suite and many more info on coding your BMW can be found online.
By running that simple job your car will be fixed!
You will have your own diagnostic and coding tools to work with and you won`t have to pay a dime at the stealership!
