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.
Jump starting If the battery in your BMW runs out, you can jump start it by attaching two jumper wires to the battery of another automobile. 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.
Can you use the trunk to jump start a BMW?
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.
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.
How do you enter the BMW trunk while the battery is dead?
You must perform the following in order to enter your BMW’s trunk while the battery is dead:
- By depressing the release button on the rear of the fob, you can remove the secret key from your key fob.
- Find the slot where your manual key goes. On select BMW models, the trunk or the lid may have a manual key slot. In that case, open the trunk.
- Find the door’s keyhole. Try the door if you can’t find anywhere to use a key on the trunk. Particularly the driver’s side door is likely to feature a place for a manual key. If so, open the car door.
- eject the concealed key container. If there doesn’t seem to be a key slot on your door, it might be hidden in a hidden compartment under the door handle. The key slot can be seen if you wedge the key into the opening beneath the compartment and pop it off. Lock the vehicle.
- For trunk access, fold down the back seats. Your jumper cables will be available to you at this time. But if you want to access the trunk from this position, a rectangular tab can be found inside the door of the trunk. When the tab is removed, a wire ought to follow. The trunk will open if the wire is pulled.
It could be time to call roadside assistance for assistance if, for any reason, you are unable to enter your car. Jerry should be brought if you don’t have roadside assistance.
For as little as $4.16 a month, Jerry provides roadside assistance that includes jumpstarts, lockouts, key replacement, and towing.

Will my car be harmed if I jump start it?
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 (ECU)
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.
Contact South Africa’s reputable battery experts if you need to jumpstart a newer vehicle instead. They will not only point you in the right direction for your nearest branch, but they will also analyze your car battery for FREE and give you recommendations for a replacement battery that is especially made for your vehicle.

Does your battery become damaged when you jump start another car?
The short answer is yes, though not in the way you might have imagined. The diodes on the alternator could theoretically be harmed by voltage spikes. Your alternator is shielded from reverse current by these diodes. If these diodes fail, your alternator may start using its own battery.
As you can see, it is crucial to make every effort to avoid jump starting. There is always a chance that something will go wrong. It is something you wouldn’t want to experience. I wouldn’t worry too much if you occasionally had to jump start your own or someone else’s car using a battery power pack. Particularly when it does not occur frequently. But it’s crucial to be informed.
