Since Christmas, a friend of mine hasn’t driven his E46 because he had access to another vehicle. Naturally, the device is now completely dead.
Do I need to take any safety measures before jumping it tomorrow? Is it feasible that doing so could harm something?
Will this be permitted by the BMW alarm/immobilizer? Is it possible to turn off the alarm even when the battery is dead—for example, by using the key to manually override it?
The alarm went off the last time the car door was opened (last week) and wouldn’t turn off with the key – it ultimately timed out!
Utilize the jump points behind the hood; the positive is a brass-colored bolt hidden beneath a cover that says “+.” One of the bolts close to the suspension turret is the negative to employ.
There is nothing else you need to do. The alarm may sound when you are doing it, so don’t be concerned. Once the juice is restored, everything will be OK.
(I jump e46s frequently, but if it blows up, it’s not my fault. This is all subject to a large disclaimer.)

Can a BMW be jump-started safely?
DO NOT let any roadside assistance agency install a new battery in your BMW, and DO NOT jump start the vehicle. It might cost more than any other battery or jump start you’ve ever purchased.
Will a BMW jump from the trunk?
The fact that jumpstarting procedures for a BMW are remarkably similar to those for any other brand surprises a lot of Greenwich drivers. Although many BMW batteries are located in the trunk, restart connectors are located underneath the hood.
How can you start a BMW in terminal 15?
Regarding keyless ignition switches, I have a stupid query. I’ve seen that as a first step, you “change your ignition switch to R or terminal 15” in a number of manuals and how-to instruction pamphlets. Could someone kindly explain how a 2005 745i keyless ignition works? See, I warned you that was foolish, but I’m not really sure of the solution. Thanks
what instructions should be included in flyers? You intend to start the vehicle. Put the remote in your lap, depress the brake, and push the start/stop button while sitting in the car.
On a BMW, where do you place the jumper cables?
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.
What is the time required to jump start a car?
Jumpstarting your car should only take a few minutes once the cables are connected. like five minutes at most in regular circumstances and thirty minutes in dire circumstances. After starting the car, you must drive for at least 15 minutes for the battery to fully recharge.
In the BMW trunk, where is the battery?
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.
Where is the BMW 3 Series battery?
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.
In a BMW 4 Series, where is the negative battery terminal located?
Under the hood, there is a positive battery terminal, and on the left side of the frame, there is a negative post. When jumping, you connect jumper cables to these poles. Under the hood, there is a positive battery terminal, and on the left side of the frame, there is a negative post.
Will giving someone a jump start do damage to my car?
It is honorable to provide a helpful hand. You can consider letting someone use your car to jumpstart theirs if you observe them with a dead battery. You might be concerned that it might harm your car in the process, though. You want to help, but you don’t want to do anything to harm your car.
Giving someone else’s automobile a jump start will typically not cause any damage to your own. They would control your battery, but you could simply use your car to replenish it. If the jumpstart is effective, the donor automobile doesn’t actually sustain any significant harm. However, there is a good potential that your automobile will be destroyed if the jumpstart is not done correctly. Here’s how to go about doing that:
Why is the battery in the trunk according to BMW?
Instead of the more conventional engine-bay-mounted battery, the majority of BMW vehicles use a trunk-mounted battery. Because of the constrained engine bay space (a powerful engine must fit into a tiny space) and the need to maintain a weight distribution that is as close to 50/50 as possible.
What occurs when the battery in a BMW is low?
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.
How come my BMW asks to charge the battery?
When your battery is below the recommended state of charge, your BMW may issue one of three degrees of warning. Level 1: The car appears to be functioning normally, but there is a caution message that reads, “Charge Battery.” NO servicing is required at this time; this is merely a notification.
What is a bad idea when jumping a car?
- Avoid smoking.
- without donning gloves and safety glasses
- neglecting to read the owner’s manual.
- If the battery has a leak or is fractured, don’t jump start the vehicle.
- not engaging the park brake.
- Keep the cords from dangling from the car.
- Avoid using cheap, subpar cables.
Can you use the trunk to charge a BMW battery?
My installation is in the trunk. It’s usually preferable to have the charger as close to the battery as feasible when it comes to charging. The negative lead should be linked to the chassis, not the battery, and the positive lead should be attached to the battery terminal.
When jumping an automobile, why don’t you connect the negative?
Shortcuts for Jumpstarting a Battery Never attach the black line to the dead battery’s negative (-) terminal. This could cause an explosion, making it extremely dangerous.
Can the ECU of a car be harmed by a jumpstart?
The electronic systems of a modern car can be harmed by a power spike, much like most electronics. A seemingly innocent jumpstart may result in the power surge mentioned before, which may affect the performance of the onboard computers and safety features, harm the engine, and necessitate costly repairs.
The recognized battery experts have examined numerous vehicles that consumers have brought in over the years after attempting to jumpstart them. Among the damages were
Engine Control Unit Blown
If there is a voltage surge during jumpstarting, a blown ECU may result. The alternator and other electrical parts, including the fuel pump, onboard computer, and perhaps the fuses, are affected by this.
traction control systems with compromises
Always follow the manufacturer’s directions when jumpstarting a vehicle with traction control. Failure to adhere to these guidelines may result in degraded traction control, unstable road grip, and potential hazard to the driver and other drivers.
harm to power steering
The power steering system may be compromised if the manufacturer’s recommendations are not followed, making maneuvering your automobile more difficult than usual. This might be hazardous.
Bugs in the airbag system
Modern vehicles may have airbag system instability after a starter, which might cause the airbags to malfunction and fail to deploy. The results can be disastrous.
Start/Stop systems that are inconsistent
The majority of contemporary automobiles have Start/Stop technology. If you jumpstart your automobile improperly, the Start/Stop system could be disabled, necessitating further inspection at a dealership. It is not suggested to jumpstart a car with Start/Stop technology because the battery is made specifically for that vehicle.
Injury to the boosting vehicle
When a newer vehicle is used to jumpstart an older one, the newer vehicle may experience a power surge that damages its pricey electronic equipment.

Can a car jump damage your battery?
- A broken battery should not be jumpstarted. The battery may be damaged if there is visible physical damage, a rotten-egg smell, or if the car won’t start after only a brief time of rest.
- If you’re certain the battery isn’t damaged, carefully adhere to the detailed directions in the owner’s manual because every automobile has a distinct process.
- Use only spike-protected jumper leads of the highest caliber. Make that the jumper leads are connected correctly and oriented according to the manufacturer’s instructions. These essential first procedures must be followed in order to avoid costly repairs or a write-off.
How are the negative jumper cables connected?
The positive (red) cable needs to be connected to each battery’s positive terminals. The negative (black) cable needs to have one end grounded and the other end connected to the dead battery’s negative terminal.
How can I tell if my ECU is broken?
Because your engine’s timing and fuel consumption are controlled by the ECU, you may have performance problems with your engine, such as lagging or surging, if the module is failing. For instance, your car will lag or stutter when you press the accelerator if the engine isn’t getting enough fuel because the malfunctioning ECU has messed up the air/fuel ratio. Your engine may surge if you use too much fuel, which can lower your fuel efficiency. The timing of your engine might also be messed up by the ECU.
