Hi. Since the battery is in the back of my 2008 328xi, I assume there are + & – connectors close to the engine. Can someone quickly walk me through the process of using my bmw to jump start a different car that isn’t a BMW? Any assistance would be greatly appreciated.
starting up Two jumper cables can be attached to the battery of another vehicle to start your BMW’s engine if the car’s own battery is dead. The similar approach can be used to assist with starting a different car. Use only jumper cables with clamp grips that are completely insulated. When the engine is running, do not touch any electrically live parts as this could result in a deadly accident. Follow the steps below carefully to avoid damaging either vehicle or raising any safety concerns.
vehicle has a voltage of 12 volts and a capacitance that is almost equal, measured in Ah. On the battery, you can find this information.
There should be no physical touch between the two cars’ bodies to prevent shorting.

I’ve successfully jumped another car with the BMW jumper studs.
Very effective. Be warned that the jumper cables you buy will likely be of insufficient gauge unless you spend at least $40. Jumper cables often come in 10 gauge. If you’re very patient, 10 gauge will function. After you hook them up, you have to wait around five minutes before using the second automobile. Attempt that again after waiting ten minutes.
Good jumper cables, on the other hand, are 20′ length and 4 gauge. You can jump a car from behind with 20′, which is important if the dead car is parked and you can’t park head-on. Since there is no actual lag in waiting for the dead car to build up a charge, you can link them up and try the dead car right away with 4 gauge.
Has anyone tried using their G01 X3 to jump-start another vehicle’s battery? I’m not referring to the X3 itself.
I attempted to jump start another automobile using the battery terminal under the hood, but I was unable to supply enough power. As I always do, before attempting to start the second car, I connect the jumper and crank the engine for a while to partially charge the dead battery.
However, I was unable to start the other car with the X3 because nothing I tried seemed to be able to get the X3 to charge the other car’s battery or supply enough power. even after leaving the cords connected for 10 or 15 minutes. I had to jump start the car using my older 335I.
I am aware that the X3 only charges its battery when necessary and while you are coasting or braking.
When I read the instructions, all that it mentions is how to jump-start the X3. I want to know whether it is feasible to jump start another vehicle with the X3 and, if so, how to get the charging system to work while doing so.
I’m aware that this isn’t a direct response to your query, but I’m done using a different automobile to jumpstart either mine or someone else’s. About a year ago, I invested in this travel charger, and it has been completely worthwhile. Many different cars, even those with fully dead batteries, have been jumpstarted by me. I simply store it in the trunk’s floor compartment.
With my ’20 M40i, I had to jump start my wife’s car a few times. had no issues utilizing terminals inside. The other car’s battery might have been shorted or had some severe flaw that prevented your effort from succeeding.
Nothing I tried seemed to be able to get the X3 to charge the other car’s battery or provide enough power to start the other car, thus I was unable to jump start it.
Just to be sure, did you choose a negative jump terminal of your “own” choosing, presuming that it was a real ground, or did you use both dedicated neg/pos terminals in the engine bay? Some owners will attempt a jump or charge utilizing some of the strut tower bolts or other “metal” elements in the engine compartment in the mistaken belief that they are a true ground, but they aren’t.
How to Restart a BMW’s Dead Car Battery
You can use jumper cables and the power from another running vehicle to jump-start a BMW in order to recharge a dead battery. Although the battery is stored in the back of BMW vehicles, you may jump-start them from the front. The red positive (+) connector is located next to the engine and under the hood. You must wait for the battery to fully recharge after starting it before turning it off again.
How do I use my BMW to jumpstart another vehicle?
Connect one of the red clamps to the positive (red) terminal on your own BMW vehicle. Connect the other red clamp to the helping vehicle’s positive (red) terminal. Connect the negative (black) terminal of the assistance vehicle to the black clamp. The other black clip should be fastened to any bare metal surface on your car.
Can I jump-start another vehicle with a new one?
Is it accurate to say that you shouldn’t ever jump a newer model automobile because it harms both cars?

Answer:
It is untrue that jump-starting a newer model car will result in harm to both the cars involved.
Explanation:
According to our specialists, newer model cars are typically categorized as being built after 2005. These models might be trickier.
“There are so many computers and other potentially dangerous components in automobiles. Because the battery is not always in plain sight, it is more challenging. It’s frequently more difficult to simply connect the cords to them because they’ve been placed in the trunks and behind the back seats “Ramsey stated.
Nevertheless, our experts concur that it is still possible to jump-start one. However, you should be aware of the proper technique.
“When a system experiences overvoltage, a set of regulator diodes blow, which can lead to a cascade problem. Observing the manufacturer’s guidelines, which may include instructions on how to connect and unplug your battery, “Schuman stated.
According to the experts, you should call a roadside assistance service or take that model of automobile to an auto body shop if you don’t know exactly what you’re doing when it comes to jumping it.
Will my car be harmed if I jump start it?
If done incorrectly, jumping your own automobile can harm the vehicle. More electronics than ever are built into modern vehicles. The electronics in your car may get damaged if you jump it improperly. The incorrect terminal placement may cause a short circuit or possibly irreparable damage to certain components.
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.
Can starting a car with a jump damage your sensors?
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.

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.
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.
