Reasons that prevent your Mercedes Benz E Class 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 Mercedes Benz E Class

In most cases, for a Mercedes Benz E Class that does not start, the battery is implicated because it gives the starter the energy required to start the engine.
Check if there are any lights on your dashboard. Refer to the light on to point 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 Mercedes Benz E Class, 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 leaving even if your car is on, you don’t wish to stall at the first traffic light and have to repeat the operation.

Weather conditions

Let’s go forward. Let’s imagine that your battery is recharged, but unfortunately your Mercedes Benz E Class still doesn’t start. First, it is important 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 necessary to clean them. It is possible to do this with a wire brush or sandpaper. Make use of a small amount of thick grease before rubbing.

Starter of your Mercedes Benz E Class

Now you have followed our advice so far but your Mercedes Benz E Class still doesn’t react. It is now time to focus 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 loosen the coals and facilitate their passage.
It should also be noted that this part does not have a specific lifetime, everything will be based upon its use and consequently on the maintenance of your Mercedes Benz E Class. When it no longer works well, it is often caused by a bad electrical contact, itself often caused by high summer heat. This reduces the conductivity of metals. If the weather is not hot, it is not responsible

Another technique to try to launch your car is to put your Mercedes Benz E Class on a slope and by playing the clutch pedal, the engine will sooner or later start. This will succeed 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 Mercedes Benz E Class

If, on the other hand, 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 role 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 defective alternator.
