Where Is Battery On BMW?

The majority of brand-new BMW vehicles are constructed with their batteries in the trunk, unlike practically all other vehicles. Now that we’ve cleared things out, learning how to remove a car battery won’t take much time: Under the upholstery that covers your trunk, the battery is often found on the right side of your car.

Procedure

  • The ignition key should be removed. Remove the key from the ignition of your BMW 3-Series before changing the battery. The electrical system of a BMW can be sensitive to voltage drops, and leaving the key in the ignition can result in issues.
  • Find the battery. Open the trunk. The battery is in the trunk of your BMW 3-Series. You must take off the cover on the right side of the trunk in order to reach the battery.
  • To access the battery, remove the panel.
  • Negative cable disconnected. Start by unplugging your BMW’s negative battery terminal.
  • Unplug the positive cable. Avoid making any connections that could short the positive and negative battery contacts.
  • Take the battery bracket off. Here is a close-up of your BMW 3-Series’ battery bracket.
  • Use a terminal brush to clean the battery terminals on your BMW 3-Series. This will guarantee a solid connection between the battery post and clamp.
  • Connect the battery connections after installing the new battery. First, attach your BMW 3-Series to the positive battery post. Add the negative terminal last. To stop the battery terminals from corroding, use a battery fiber washer.
  • Shield the terminals. On the battery clamps and posts, spray battery terminal protector. The metal surfaces are helped to seal by a battery guard. It enhances current flow and lessens corrosion.
  • Start the car. The steering wheel should be turned left, then right. To reset the steering angle sensor and the DSC light, repeat this step numerous times.

In a BMW 3 Series, where is the car battery located?

The engine compartment does not include the 3 Series battery; it is located in the boot. Remove the floor panel from the boot by raising it. The battery is concealed by a plastic battery cover with three fasteners on the right side of the boot.

A 2011 BMW 535i’s battery can be found where?

Near the tiny cubby hole in the trunk is where the battery is located. I’ve captured a photo of the trunk without the gray cover. THANK YOU SO MUCH! Near the tiny cubby hole in the trunk is where the battery is located.

What is that on the BMW battery’s top?

What I believe to be the key fob adaptor for charging the original fob is seen in the photo below.

I would be very grateful for any information on this setup. It can be found in the trunk of a 2009 E87 120i hatchback.

David, the grey object is plainly a battery. The positive terminal is accessible through a small red box, and the other terminal is connected to earth.

You will observe another red box (about 150 mm x 200 mm x 25 mm). This is the box in concern. Using knowledge of the approximate dimensions of the battery, you may identify it.

I think a key fob may fit in the two slots on the right side of the red box in the picture.

We would appreciate any assistance. Keep in mind that the smaller red box contains, I believe, a fuse or an off switch.

You will observe another red box (about 150 mm x 200 mm x 2.5 mm). This is the box in concern. Using knowledge of the approximate size of the battery, you may identify it.

You can see a wire termination if you look inside those slots. Those openings are only bare plugs for different wiring possibilities. A large multi fuse is what the large component covered in red actually is. A year or so ago, BMW performed a recal on select 3 series vehicles due to a poor battery connection, and while they were working on my 328i, they actually blew one of the main fuses, which made it take the technician two days to diagnose the problem.

Thank you, David I think you’re right. It is merely a block for distributing power. It is Part #61146971370, according to another forum.

I still need to know if it has additional fuses or any electronics that need to be coded in order to replace the battery.

Note (15/Jan 2015): There are no electronics; it seems to have extra fuses! (To be verified)

Does BMW require a unique battery?

Finding a great BMW battery is one of the most crucial factors to take into account if you want the best for your luxury vehicle. For the best performance on the road, you must purchase a BMW car battery that satisfies the strict criteria of the vehicle.

The 5, 6, and 7 Series BMW vehicles typically have very high features. These automobiles need a lot more energy than your typical car does, thus we strongly advise obtaining them strong batteries.

You must be aware of your vehicle’s needs before purchasing a BMW battery. An Absorbent Glass Matt (AGM) battery is strongly advised for modern BMW vehicles with start-stop technology since it can handle the increased energy demand. However, you can also utilize an Enhanced Flooded Battery (EFB) if you want to buy something for less money.

Just keep in mind that you should only replace the original AGM battery in your BMW vehicle with another AGM. Because these vehicles weren’t intended to be utilized with EFBs, downgrading will cause battery and engine problems with your BMW. On the other hand, if your BMW came with an EFB at the factory, switching to an AGM battery won’t cause any issues.

EFBs outlive ordinary batteries in terms of longevity. They were created specifically for entry-level start-stop vehicles, so they can easily handle the rigorous needs of the majority of modern automobiles.

However, you should always choose an AGM battery if you want to spend more money on a more potent BMW battery. Although these batteries are made for start-stop vehicles, they are also compatible with other energy-consuming vehicles.

In comparison to conventional batteries, they offer a three times longer cycle life and may be utilized in all kinds of weather. Additionally, an AGM battery is necessary if you frequently use the car’s accessories.

BMWs with typical power requirements can be powered by standard automobile batteries. Therefore, if your car doesn’t have high-end gadgets or a start-stop system, you don’t require a special BMW car battery.

What occurs if the battery in a BMW dies?

After you turn off your BMW, your battery continues to run for a while. After you leave, it will continue to run your radio, lights, clock, and even the security alarm for the car. Electrical issues with your BMW could cause some components to turn off while others, like your lights, remain on, draining your battery. When you leave your BMW, make sure all electric components are turned off.

Can I change the battery in my BMW myself?

Do you not adore your BMW? And you intend to continue using it for as long as possible, right? Change your oil, replace your air filters, and do other routine maintenance on your BMW as needed to ensure its longevity. Maintaining the battery in your BMW, however, is the one item that contributes the most to flawless operation of your vehicle.

However, a lot of individuals ponder whether BMW battery replacement and registration are straightforward do-it-yourself tasks or require the services of a qualified specialist. We affirm that you can manage the replacement on your own. However, if you lack computer literacy, let us handle the registration process on your behalf.

Here, we’ll go over how to install a battery in a car, examine BMW battery registration in further detail, and provide additional information on the BMW battery reset process.

How can I tell if the battery in my BMW is bad?

Your battery has to be replaced if your vehicle cranks while starting, starts slowly, or does not start at all. All of your car’s electrical components, including the headlights, radio, windshield wipers, and power windows, are powered by the battery.

Why won’t my BMW start despite clicking?

When trying to start your car, a loud clicking sound may indicate an issue with the electrical system. It’s possible that your battery is dead or that the alternator, which charges the battery, is malfunctioning.

The starter, a small motor powered by the battery that starts the engine, is unable to maintain power if the clicking noise is electrical in origin. Instead, it makes a clicking sound and switches on and off quickly.

Remember that in situations like this, a misfiring starter is really a symptom and not the root of the problem. Your automobile’s electrical system is probably to blame, which is why a jumpstart could briefly move your car.

Once it’s operating, have an experienced technician inspect the entire electrical system. Your alternator or battery might need to be replaced. Alternately, the issue might be resolved by simply cleaning the battery terminals of corrosion to improve the battery’s connection.

You’re not the only one having issues with your automobile battery. According to AAA, among the top three reasons members call for roadside assistance are battery issues, with the majority of those calls occurring in the summer.

How are jumper cables attached to a BMW?

It’s crucial to connect the jumper cables in the proper sequence: Connect one of the red clamps to the deceased vehicle’s positive (POS / +) terminal. The positive terminal on the operating vehicle should receive the other red clamp. Connect one of the black clamps to the working vehicle’s negative (NEG / -) connector.

How is a BMW 3 Series jumpstarted?

One red clamp should be connected to the vehicle’s positive terminal. The positive terminal on the operating vehicle should receive the other red clamp. Connect one of the black clamps to the functioning vehicle’s negative terminal. Attach the second black clamp on the non-operational vehicle’s unpainted metal surface.

How can you use a dead key fob to start a BMW?

You won’t be able to use keyless entry or remote unlocking if your BMW has Comfort Access if the battery in your key fob has died. You can still enter and manually start your automobile, though.

Press and hold the key release button at the remote fob’s base while unlocking the door of your car, then slide out the internal key blade. This can be used in place of a standard key to unlock your car. You can locate a little hole on the bottom of the handle if the keyhole is hidden on your car door. Use the key blade to pry off the trim panel and expose the keyhole by inserting it into the hole.

Once you’re inside, put your remote key fob in the ignition slot or, if your car doesn’t have one, press it up against the steering column’s key markings. If your key fob dies, you will still be able to start your BMW using the start/stop button on the dashboard.
