First, we will try to find the reasons that might prevent your car from starting.
It is also possible that your car crancks but won’t start.
Reasons that prevent your BMW X5 from starting
The battery may not have supported leaving your headlights on all night, or the vehicle key may have been forgotten on the ignition.
To check that it comes from the battery, and not from other causes, first check the lighting of your headlights. Indeed, a low intensity or no lighting might be a bad sign for your battery.
Let’s see the different causes of failure
Battery pack of your BMW X5
In most cases, for a BMW X5 that does not start, the battery is implicated because it gives the starter the energy required to start the engine.
Verify if there are any lights on your dashboard. Refer to the light on to indicate the failure.
If when turning the key you can feel jolts, this is a sign of a weak battery, and consequently it needs to be recharged.
A little trick that may help you a lot is to keep jumper cables in your BMW X5, you will save yourself a towing.
If someone you know has the cables themselves, they can recharge your battery enough for you to restart the engine and the battery to recharge itself. Wait for a moment before starting even if your car is on, you don’t need to stall at the first traffic light and have to perform the operation.
Let’s go forward. Let’s imagine that your battery is recharged, but sadly your BMW X5 still doesn’t start. First, it is crucial to know that humidity and temperature changes generate oxidation that can deposit on the battery terminals, clogging it and preventing it from working.
When in good working order, the terminals are a metallic grey. If they have changed colour, it is important to clean them. It is possible to do this with a wire brush or sandpaper. Apply a small amount of thick grease before rubbing.
Starter of your BMW X5
Now you have put into practice our advice so far but your BMW X5 still doesn’t react. It is now time to focus your attention on the starter, the small electric motor that starts the car’s engine.
You should know that to keep it in perfect working order, a few simple and quick steps are required. You can give a few small jolts on the sharp part of the starter, which will release the coals and help in their passage.
It should also be noted that this part does not have a specific lifetime, everything will rely upon its use and as a result on the maintenance of your BMW X5. When it no longer works well, it is often caused by a bad electrical contact, itself often brought about by high summer heat. This lowers the conductivity of metals. If the weather is not hot, it is notto be blamed for
Another technique to try to launch your car is to put your BMW X5 on a slope and by using the clutch pedal, the engine will eventually start. This will work if your battery is dead and it has not been used to start the starter. In this solution, this trick avoids solliciting it.
Alternator of your BMW X5
If, however, after driving, your battery has not recharged, (so you still cannot restart your engine with the contact even after driving) two options, either your battery is dead, or it’s the alternator. Its function is to recharge it while driving. This means that your battery may be in good condition, but it has simply not been recharged by the faulty alternator.
If despite all this you are incapable determine the failure, it is still recommended to see a professional who can make a diagnosis to be more reliable. Keep in mind everything that has been mentioned in order for you to supply him with information that could help him/her to repair your BMW X5.
