I’m new to BMW ownership - about a month. That being said my owners manual says I can jump start the car using the starting aid terminals under the hood. They even call them “starting aid terminals”. It says to switch off all electronics in both cars and connect cables with both cars off in the proper order, then follow next steps, etc. It does say to strictly adhere to the procedure or risk damage to vehicles or persons. Maybe people aren’t adhering to the procedure and damaging their cars, but if I need a jump and don’t have the portable jump starter, I don’t see why to not jump start the car using the written procedure in the manual. I do think that the portable jump starter is probably a good idea though. Interestingly enough, it doesn’t say anything about using a portable jump starter in the manual. Loving the car so far.
So german engineering isn't capable of protecting an ecu bms. Etc etc but they can build cars with massive built in issues that cause engine damage. Oh I see
German engineering does protect the ECUs, that is why the connections for jump starting are in the engine bay and they put the instructions in the Owner's Manual.
Well they can be sensitive jump starting. Rule is, only jump a slightly soft battery maybe but never jump a flat battery, allow some time for some charge to build up in the BMW battery first ;). I think the main problems can occur when jumping a very dead/flat battery, when the BMWs battery voltage suddenly sags whilst cranking the engine over and the other jump cars alternator and the BMWs alternator can spike above 15v widely trying to compensate the load, coupled with the cars voltage regulation strategy, which can cause over voltage spikes to damage modules. Superior engineering or guaranteed dealer network income?
Jumping from under the hood with jumper cables is fine, it even explains it in the manual how to. I would suggest to connect all 4 cables with both cars off and then just try and start to dead one. If still not enough, then start the good car and then try the bad one again.
I am a female who prides herself on researching, learning, and quite a few minor repairs. Just realizing now I'm not as smart as I thought I was. I am on my 5th BMW and I can honestly say probably my last. I have a 2008 535i , beautiful car, rides great but it's just one thing after another, I can afford to buy one but not always afford to get it fixed. Thank you so so much for the battery information, never have I thought to look up how to charge the battery cuz I just figured you charge it like any other car and boy was I wrong. Once again very very helpful I guess I'll have to go out and buy one of the chargers and try to get my car started I'll let you know how it goes once again thank you so much. Signing off, Annemarie from Florida
I have a 2010 535i and love the car. Unfortunately it's my first and I got it 6 months ago. It stalled out on me again today. This time it left me stranded in a busy highway. I was terrified. So it's been towed and at the mechanics twice in 6 months. It's so expensive for repair work. It's hard to attempt any preventative maintenance.
I had an 08 535i in Florida as well. Amazing car but the n54 is notorious for being unreliable. Don’t give up on bmw. The newer models are way more reliable. I drive a 18 540xi now with the b58. Even tuned the car feels like it’s holding back. Super reliable engines.
That currently makes literally no sense to me from an electrical engineering point of view. I can’t see how the car will see any difference between one battery or two in parallel even if one is discharged. Possibly the 14.5V of a running car might over voltage the starting systems that would normally only see very low volts whilst the starter is cranking. Very odd. I always understood that the battery was in the rear merely to assist with weight distribution. I must go and look at the circuit diagrams. Definitely agree about the jumper packs with the smart connection monitor though. Getting the polarity wrong when jumping is definitely catastrophic and often ends in a battery explosion raining acid everywhere.
As a EE too, I agree. But let the BMW owners think what they will. I charge my Z3 from the trunk (boot), but I jump start it from the hood (bonnet) all for convenience's sake.
I agree that it's probably fine to jump from the front. Honestly, any automotive system that can't handle at least 16V and transients is incredibly poorly engineered.
Old BMW's don't seem to care. Most bmw's also have batteries that last like 10 years too, because they are big and trunk mounted. The e60 shown here has notoriously dodgy electrical systems. They also were the first bmw's with lead free solder and computers in the trunk that tend to get wet. Don't get an e60, so many electrical gremlins.
Hello there , same thing happend to me , modules dead , no electricity found afterwards and i had to go to bmw because i had no idea what was the problem , paid 800€ to fix it , you doc are a beast , listen to the doc everyone !
So I got a E90 and how I got it is mysterious won’t start. Well they jumped it with a bigger and bigger amp jump pack. So I found the fuse block being how I got it to start again by unplugging all relays then plug in. But how I got it to start consistently is I unplugged and plugged the jbe and now it’s Ben starting. Still a bit mysterious but I’m at the problem area with no scanners or shops 🧐. : got it it was a burned fuse block. Swapped it out and problems are gone. One hell of a process !!!!
Hello what do you mean fuse block? The WHOLE fuse box that contains the fuses and other blocks inside … or only one of those blocks inside to replace ?
I did not know this, I know not to jump start it from the battery but a few time in the 1st lockdown my BMW X5 e53, got a flat battery not being in use and I jump started it with leads twice using the wife’s ford, unlucky had no issues or problems 🙏👍
BMW and other manufacturers put batteries in the boot/trunk for several reasons. 1 Weight distribution 2 Cooler away from the engine (and batteries don't like excess heat or cold) 3 Packaging - on the bigger engines there just isn't space under the bonnet Does no one read a car manual these days.

So let me get this straight, you can not jump it from the back, and you can not jump it from the jump terminals unless you use jump stater. I have a better idea, Do not buy BMW at all. Problem solved
There nothing wrong with using jump cables on the front terminals, just don't start the car that's providing the juice. The guy in the video is in fact using jump leads between the terminals and the power pack, they're just very short.
A lot of modern cars with start stop systems and intelligent charge systems have alternators capable of putting out a lot more voltage and amperage than an older conventional system where the alternator regulator will maintain around 14 volts max these systems can output a lot more voltage dependant on demand. So if you have to use another vehicles battery on the terminals and you don't have a jump pack, do not start the engine. Not only BMW but some Vauxhalls as well can be seriously damaged by jumping direct to battery, some have the jump terminals despite the battery being in the engine compartment under a cover.
Never had to jump start my BMW but had to jump start other cars. Always used this front terminals, is it better to jump start other cars from front as well?
Well I’m late to seeing this and I jump started 2017 330i from the battery the old fashioned way. And nothing is damaged that I know of. Fingers crossed. But I bought the instrument in the video for future charges.
The dead battery is say like 9v so if you have a running car and connect the two cables it will have a voltage of 13.7-14.2 V. Once you connect them to the bmw battery it starts to charge the battery but it will cause spike in charging current that may damage the battery but proabably it won’t be that high, idk maybe 30A for 2-3 seconds. But that should not affect any system since the current flow is between the battery and the other car. At the same time voltage will rise quickly, maybe faster than with a normal charger but the same thing happens if you connect the cables to the front terminals since the cables have low resistance(large section area). If you start the car within a minute the flow of current will be from the other car through the cables between the battery terminals and the starter through the car cables. In the case you connect them to the front the flow will be between the other car through the cables and then through the shorter cables of the bmw to the starter so a shorter path thus slightly more current available. Anyway it may be as you said and it could damage the car, maybe something is missing from the picture.
@@bystander1489 idk I’ve found more reasons: a spark in the trunk can cause a fire because batteries leak hydrogen during charging. Mine has a vent hose that goes under the car
My previous car, an audi had the same setup. I never had to jump start it thank god because despite all the tinkering I did changing air filters etc, I didn't see there were terminals under the bonnet! Only found out by googling it now. I had this car 4 years. I'm just glad I never left the lights on overnight! Great advice, it should be included in the quick reference manual too. The F20 I took ownership of a couple of weeks ago also has this layout. Thanks for the advice!
I've tried to jumpstart my e87 118D the correct way from the hood in winter but it just never works for me, it does not deliver enough power to the battery to start the car, but when i jumpstart from the battery itself from the trunk it starts instantly, might be the incorrect way but it acctually works for my car.
I got one of these jump starters. Bought it a few months ago. Had to use it for my f10 3.0 diesel last week. Worked like a charm . (The only prob is the leads are quiet short and just about reached the earth point)
@@egotbands2145 Best thing to check first, is the BST Postive Cable, and/or the Battery Distribution Box, that's the red plastic box, that sits on the battery. The fuse inside fries. And blows out.
Quick question. I need to use my BMW e71 X6 to charge the battery out of my E90. If I connect the battery to the terminal at the front via jump leads, will it charge?
Hi. Quick question will this work with a M3 2016 plate with a lithium battery because I've heard that jumping a lithium will just make the battery go boom.
speaking of "german engineering" the only car I've ever had to jump start is BMW, as well as the only car which wheel falls apart after hitting a pothole.. absolute garbage Ive had Kia's and Honda's getting to 200,000 miles without any issues.
My son jumped my m4 with another car. The electrical system is now messed up, and the radio / audio is not working. How can I fix this? The dealership did diagnostics but they are unable to figure out how to fix it. Can you help?
Fucck bmw , jump started my bmw and blew the footwell control unit ! Great 👍 Bought a topdon jump starter previously and it was faulty and sent it back ! Fffsss Central locking not working , indicators not working etc etc
The BMW manual says to jump start the car with another car, following the simple procedure. So no need to overcomplicate things and having to buy a jump starter.
😂 “German engineers are very intelligent” … goes on to explain how overcomplicated the car is. Like that thing has all the same features and works as well if not worse than my Subaru…
Good info my guy. I was E39er back in the day did most of the work myself of coarse and looking to get an F85 soon. What "jumppack" do you recommend or would the one in one in the vid work as well. Keep up the good work!!!
Thank you!!!! Finally... Someone who addressed the specific important data points of this procedure. thank you😎⚡🔥 Too many other videos spend too much time talking about unimportant details.
Hi there. I have a friends car here a 520 diesel and i only get 3 volts at the front. But at the battery i have full power. So i jumpstarted it and it starts. But not charing.
I had to jump my E93 once with jumper cables and another car. I followed Scotty Kilmer's advice: never connect two modern cars with jumper cables while both cars are running. So I hooked up the cables. Then let the good car run for a few minutes. Then shut off the good car. Then started the bad car. Then disconnect the cables. It worked with no damage to either car. Is this good advice or did I just get lucky? Cheers Mate 😄
Connect the cables, positive first and then negative, with the engines off. Start the car with the good battery and let it run for a minute or so. Then start the car with the duff battery. Let both idle for a few minutes. Disconnect the cables in the reverse order. N.B. some say that you should switch both cars off first, but that risks putting you back to not being able to start the car with the flat battery as a few minutes jumped will not put any sort of charge in a flat battery.. Never had a problem with disconnecting the jump leads from another car or a booster pack while tthe car is running.
From the car that you jumped from, did you go directly to the battery or use another car that had under hood posts? There are a lot of options to jump starting a vehicle that won't start. In using another car to jump, it is important to understand how the car's electrical system is designed in suitability to jump another vehicle. This is Scotty's concern in using the term "modern". For example you would not use the under hood posts from a late model BMW to jump another car. The large draw during cranking the dead vehicle could over stress the BMW 12V system. This is because electrically you are jumping from a relatively long pair of wires which include fuses that then connect to the battery in the trunk. For a high current starter draw electrically this is much different than a high current connection directly at the battery posts. Also, you would not jump from the BMW by directly going to the battery posts in the trunk with the vehicle still connected. Here again there is a possibility of over volting the BMW in providing high starting current. And after the dead vehicle starts, what the alternator outputs. Also, and what happens to system voltage when you disconnect the jumped from (source battery) cables. So, obviously a BMW with under hood terminals is not a suitable vehicle to provide a jump. Really the best thing to do depends on the state of the dead battery. Obviously, the vehicle with the dead battery will not crank (start). So, the battery is basically dead. However, the battery may also be damaged, that is, has a bad cell. A little bit of analysis is probably the best starting point. For example use a DMM to measure the powered down voltage of the dead vehicle at the jump start posts (vehicle key off) and if the voltage is 11.5V or higher there is no real concern about a shorted cell. Then, ideally you would use a smart charger/power supply (no reverse current) match voltage, connected to the under hood posts and ramp up the voltage slowly until you flow about 0.1 C (10% of the battery capacity) current (e.g. a 100Ah battery = 100 C, so 0.1 C = 10 Amps) and observe how quickly the battery takes a charge while limiting the voltage at the under hood terminals to about 14.0 volts. You would then charge the dead battery from the underhood posts in this way for about 30 minutes while maintaining the 0.1 C current rate making sure to limit the maximum voltage to 14.0 Volts. After about 30 minutes, ramp down the charger/power supply until the dead battery stops drawing current and disconnect from the under hood posts. Then try and crank the dead vehicle. If you jump from a running vehicle, or connect when the vehicle is off and then start the vehicle, the car's alternator/regulator and control electronics will try and compenstate for the added load (dead vehicle battery) while running. This may potentially over volt the BMW depending on the jumped from vehicles electrical design. For example, the alternator may be commanded, based on the added load of the dead battery, to increase the output voltage to beyond 16 Volts (which would over volt the BMW with an AGM battery). So, I think you can see the potential problem when introducing the operation of an alternator when both vehicles are jumped. We do not know what the alternator behavior will be when the vehicle is started (alternator output effecting the jumped from vehicle), or what the dead battery alternator output will do when disconnecting the jumper cables, sudden change in load. The only real safe option, if the battery does not have a bad cell and is not frozed, is to essentially try and do a rapid controlled charge of 0.1 C (0.2 C rate max) for 30 to 60 minutes. Disconnect the charger and see if the dead battery vehicle will now start. In this way you eliminate an alternator high voltage output by compensating for the unusual high load, and there is no system voltage disruption (overvoltage spike) when disconnecting the source battery.
E39 530D Tried once. Confirm blown module after jump starting from the battery. NOTE: the old-fashioned big 12v lead acid jumpstarters are 12.8v ish checked my new 12v lithium/ion jumpstarter 17.6v hence the voltage spike. Lesson learned🙁
95% sure I will have to jump start my e90 325d when I get back, it will have been just over 7 months by then 😅 Luckily for my job I have a battery pack jump starter like this, slightly bigger and was banking on just using that.
Replaced the Battery and now I get a low buzzing noise when I turn off the E60 that now won't go away. Error code Supply Terminal 30E don't know if I messed up the IBS by jumping the car the wrong way before I replaced the battery. Any advice thanks
"German Engineers are clever"? My arse! I disconnected the battery to replace it with a new one. Guess what, the fxxking FRM3 module went dead! Powered windows stopped working, none of the lights inside the car works, no turn signals. The car is pretty much not safe to drive anymore. Who would have though that disconnecting batter could damage the FRM3 module! Also, people said jump starting the car can also damage your FRM3 module. BMW knew that they screwed up. If yours is damanged within 8 yr/125K, just go to the stealer to have it replaced for free. If you are over that, you will have to pay someone on ebay to reflash. Buying a new or used module will need coding. What a pain in the butt :)
So any Vehicle with under bonnet Battery hookups is best jumped from there and not from the Battery itself ? Another point is you keep mentioning BMW ONLY put the Battery in the Boot to keep it from Jump crazzies but I also see there is no room under the Bonnet to site the Battery anyway so I assume 2 reasons it's in the Boot. I use a NOCO GB150 and hopefully 3 years on you've now got a NOCO in your mits ?
BMWs can be jump started only if done according to the mannual instructions, only jump starting connectors in the bonnect should be used, connect positive cables first then negative, all consumables should be switched OFF on both cars. Start donor vehicle and let it run for at least 8 minutes then start the dead car, let both vehicles iddle for few minutes then remove negative terminals then positive. You will be fine if done this way.
A Triple-I guy did the same thing to mine also although it did start after that but I'm wondering if that might be why I'm having some issues now. Good luck sorry to hear that that sucks....
Listen bro I have bmw 2009 528i it's been parked 4 years .. two years ago I changed battery I had to tow it to shop and they replaced battery charged me 500 Now I used to start it time after time but today I need to move it and it battery is dead . Where can I buy that device what is the full name I really need help.. it is good battery it's just drains not completely but it can't start .. and I am afraid to jump it with other car.. at list what amp I it takes to start si I buy something that can set amp a on it.. I need help plz
Hi Dean I’ve jumped started my BMW from the battery now the driver and passenger windows don’t work Their in the anti lock You after keep pressing the button to get them up and down I’ve been told I have to put the car on diagnostics and turn them on In your opinion does this make sense Thanks Peter
Thanks for sharing. It would be prudent to simply follow ones Owners Manual to get the proper procedure for your specific vehicle. My 2013 BMW X3 35i indicates jumping from another vehicle is ok to do, as long as the following procedure is followed correctly: Preparation : 1.Check whether the battery of the other vehicle has a voltage of 12 volts. This information can be found on the battery. 2. Switch off the engine of the assisting vehicle. 3. Switch off any electronic systems/power consumers in both vehicles. Starting aid terminals: Connect the jumper cables in the correct order; otherwise, there is the danger of injury from sparking Connecting the cables : 1. Pull off the cap of the BMW starting aid terminal. 2. Attach one terminal clamp of the positive jumper cable to the positive terminal of the battery, or to the corresponding starting aid terminal of the vehicle providing assistance. 3. Attach the terminal clamp on the other end of the cable to the positive terminal of the battery, or to the corresponding starting aid terminal of the vehicle to be started. 4. Attach one terminal clamp of the negative jumper cable to the negative terminal of the battery, or to the corresponding engine or body ground of assisting vehicle. 5. Attach the second terminal clamp to the negative terminal of the battery, or to the corresponding engine or body ground of the vehicle to be started. Starting the engine : 1. Start the engine of the assisting vehicle and let it run for several minutes at an increased idle speed. 2. Start the engine of the vehicle being started in the usual way. If the first starting attempt is not successful, wait a few minutes before making another attempt in order to allow the discharged battery to recharge. 3. Let both engines run for several minutes. 4. Disconnect the jumper cables in the reverse order. Check the battery and recharge if necessary
So that’s a cool video, but if the jumper I have doesn’t work maybe because it’s a poor jumper or bad battery how to you replace battery if you can get the trunk open. )2016 bmwz4 e89)?
Good time Ihave Bmx6 It shows yellow car lift icon And message say the battery increase discharge while stationary Then after 2days it die I replaced the battery but still the message and i con stay After 7 days the new battery die I take it to mechanic and who diAgnosis thy check recharger and all thing they suspect but no benefit How you can fix this for me
For my 2015 BMW X3 xDrive F25 2.0 Diesel, I bought NOCO's Boost Plus GB40, along with it's Carrying Case. I also bought, for my Daughter's FIAT 500C another NOCO Boost Plus GB20 and Carrying Case.
i have owned bmws since 1995, series 7, 3, 5, and x5 resently i drive a 2017 x5 is very nice, back in the days i used to work on them a lot but now since technology is so advanced all i do is oil change and breaks, right now my x5 battery i believe started acting out but i am not sure that is the issue, today i was very close to jump start it with my portable jumpper, but some how i did not and waited and when i tried, started right up but i very lazy and the gauge needles went up and down and then dropped and then went up staying on normal iddle possition, tomorrow i wil drive to bmw dealer i hope they dont rip me off, for all that saying i just want to thank you so much for such valuble tutorial because after so many years owned these cars did not know that would coause so much damages to modules, thank you for such a good info and taking your time to go down in details, you safe my wallet from drowning and save my money, i was very close to make the problem bigger, god bless you--
BMWs have had the battery in the boot or under the back seat since the '80s with corresponding terminals in the engine bay to start the car from a booster pack or another car. First thing to do when jump starting ANY car is check the Owners Handbook. It will tell you how to jump start the car (if it can be jump started). BMWs are not particularly sensitive to being jump started (no more than any modern car) but they do have to be jump started in the right way
Thanks for this video, I have a 320d e90 and will get one of these starter packs. Can I get one of the ones in halfords? I also have a battery charger which has a repair function. Can I use it on my car and if so would it be on these terminals under the bonnet that I connect to. Just thinking ahead for the cold winter were due.

If the batt is totally flat and you jump start. when jump leads are taken off you will get a high spike voltage causing damage to the system
This clip might save alot of cars, and alot of owners wallets. Great basic stuff that is easily overlooked.
Those jumper packs never worked for me. Not enough juice. I even got a nice big one from Schumacher. BMWs are the worst designed cars ever

The dead battery is say like 9v so if you have a running car and connect the two cables it will have a voltage of 13.7-14.2 V. Once you connect them to the bmw battery it starts to charge the battery but it will cause spike in charging current that may damage the battery but proabably it won’t be that high, idk maybe 30A for 2-3 seconds. But that should not affect any system since the current flow is between the battery and the other car. At the same time voltage will rise quickly, maybe faster than with a normal charger but the same thing happens if you connect the cables to the front terminals since the cables have low resistance(large section area). If you start the car within a minute the flow of current will be from the other car through the cables between the battery terminals and the starter through the car cables. In the case you connect them to the front the flow will be between the other car through the cables and then through the shorter cables of the bmw to the starter so a shorter path thus slightly more current available.
Anyway it may be as you said and it could damage the car, maybe something is missing from the picture.

I’ve found more reasons: a spark in the trunk can cause a fire because batteries leak hydrogen during charging. Mine has a vent hose that goes under the car
My previous car, an audi had the same setup. I never had to jump start it thank god because despite all the tinkering I did changing air filters etc, I didn't see there were terminals under the bonnet! Only found out by googling it now. I had this car 4 years. I'm just glad I never left the lights on overnight! Great advice, it should be included in the quick reference manual too. The F20 I took ownership of a couple of weeks ago also has this layout. Thanks for the advice!
I've tried to jumpstart my e87 118D the correct way from the hood in winter but it just never works for me, it does not deliver enough power to the battery to start the car, but when i jumpstart from the battery itself from the trunk it starts instantly, might be the incorrect way but it acctually works for my car.
Hi sir, Just wondering if i use 1000A 12v on my bmw m4, is that ok ?
good advice mate thank you
Always connect positive first.
I got one of these jump starters. Bought it a few months ago. Had to use it for my f10 3.0 diesel last week. Worked like a charm . (The only prob is the leads are quiet short and just about reached the earth point)
Does this apply to e90 as well? And is this the Suaoki safe if the battery is completely drained? Thanks for the vid!
Bro I accidentally jump started my e90 from the battery don’t know if I messed it up car was running but didn’t turn on afterwards
@@egotbands2145 Best thing to check first, is the BST Postive Cable, and/or the Battery Distribution Box, that's the red plastic box, that sits on the battery. The fuse inside fries. And blows out.
Thanks mate for the info.
I did know this but it’s very much appreciated that you took the time to show us all why it’s important mate 🙏
is this the same to charge my battery .I want to put my battery on charge for 12 hours without taking the battery out of the car .
What were they using prior to those new type charger.
Quick question. I need to use my BMW e71 X6 to charge the battery out of my E90. If I connect the battery to the terminal at the front via jump leads, will it charge?
I have a 95 318ic and i jumped my car witht he keys in the ignition and now my car dosent wanna start but turns over :(
Your BMW sales person should tell you all this before you drive the car out onto the road - :(
Hi. Quick question will this work with a M3 2016 plate with a lithium battery because I've heard that jumping a lithium will just make the battery go boom.
What about jumping another car off your BMW? Still using the same jump points in the front?
speaking of "german engineering" the only car I've ever had to jump start is BMW, as well as the only car which wheel falls apart after hitting a pothole.. absolute garbage Ive had Kia's and Honda's getting to 200,000 miles without any issues.
My son jumped my m4 with another car. The electrical system is now messed up, and the radio / audio is not working. How can I fix this? The dealership did diagnostics but they are unable to figure out how to fix it. Can you help?
Fucck bmw , jump started my bmw and blew the footwell control unit ! Great 👍
Bought a topdon jump starter previously and it was faulty and sent it back ! Fffsss
Central locking not working , indicators not working etc etc
Damn it! I wish i saw the video before i jumped my car to the battery now i have the 2am code !
The BMW manual says to jump start the car with another car, following the simple procedure. So no need to overcomplicate things and having to buy a jump starter.
😂 “German engineers are very intelligent” … goes on to explain how overcomplicated the car is. Like that thing has all the same features and works as well if not worse than my Subaru…
Help! Left my car at a garage, battery died! They jumped it from the boot !!!!
Now got loads of errors, abs steering etc. Ibs blown?
Good info my guy. I was E39er back in the day did most of the work myself of coarse and looking to get an F85 soon. What "jumppack" do you recommend or would the one in one in the vid work as well. Keep up the good work!!!
Thanks for the video. Why does BMW not put a black negative cap on the grounding bolt?
That's crazy when most people think they can just jump like any other car like me when I tried to help someone, Uh Oh
BMW…making jump starting a car as inconvenient, awkward and annoying as possible.
Stop waving the unit around, to punctuate your speech. It's very distracting.
I did this on my 1 series and now my electricals are messing about everyday
Does this apply to the BMW X6 E71 also? Didn't hear you mentioned this model.
I jumped start my 2003 bmw e61 and it's not starting any more
What should I do
So why does the German Manuel say I can jump start mu bmw with a jump lead tho????? Mmmmmm
Very very well informed video. Clearly presented and too the point. Spot on fella.
Thank you!!!! Finally... Someone who addressed the specific important data points of this procedure.
thank you😎⚡🔥
Too many other videos spend too much time talking about unimportant details.
I wished one of my friends saw this before he jumped his Beemer from the back, he fried his modules and a computer, cost him 5K
Would the same principle apply to the BMW 520d F10?
I have a bmw x3 and everything its lock how do I now which is the negative???
I think I may have done this and now it won’t start how do I find out what I messed up I’m new to bmw
Same here, don't know what I messed up
Ex wife blew up my footwell module jumping a person's car
Great video. If you have a battery tester do carry out the tester at the same points in under the bonnet.
Will this work on the E90 as well? I have the same + & - terminals on my N52B30
What about a e39 cause I'm about to buy one that's flat and will probably end being jumped from the battery (not by me)
Not that I watched the end a realized it does how do I know it has caused damage beside the obvious engine light
CTEK CS FREE is a great booster pack alternative.
Hate BMW . Have one in garage with dead battery
What about an E89? Same rules apply?
can the car be damaged from using the battery in the boot to jumpstart someone elses car without disconnecting it from the car?
NO he already said it can't be done regardless where you hook up Jump Cables.
I jumped my car and now it doesn't start what should I look 4
I never had to jumpstart my car , but i drive a mercedes LOL
BMW Bring My Wallet. Buy a nice Toyota or Lexus.
Just another reason why ALL German cars are great POS!
Hi there. I have a friends car here a 520 diesel and i only get 3 volts at the front. But at the battery i have full power. So i jumpstarted it and it starts. But not charing.
I had to jump my E93 once with jumper cables and another car.
I followed Scotty Kilmer's advice: never connect two modern cars with jumper cables while both cars are running.
So I hooked up the cables.
Then let the good car run for a few minutes.
Then shut off the good car.
Then started the bad car.
Then disconnect the cables.
It worked with no damage to either car.
Is this good advice or did I just get lucky?
Cheers Mate 😄
Connect the cables, positive first and then negative, with the engines off.
Start the car with the good battery and let it run for a minute or so.
Then start the car with the duff battery.
Let both idle for a few minutes.
Disconnect the cables in the reverse order. N.B. some say that you should switch both cars off first, but that risks putting you back to not being able to start the car with the flat battery as a few minutes jumped will not put any sort of charge in a flat battery.. Never had a problem with disconnecting the jump leads from another car or a booster pack while tthe car is running.
From the car that you jumped from, did you go directly to the battery or use another car that had under hood posts?
There are a lot of options to jump starting a vehicle that won't start. In using another car to jump, it is important to understand how the car's electrical system is designed in suitability to jump another vehicle. This is Scotty's concern in using the term "modern". For example you would not use the under hood posts from a late model BMW to jump another car. The large draw during cranking the dead vehicle could over stress the BMW 12V system. This is because electrically you are jumping from a relatively long pair of wires which include fuses that then connect to the battery in the trunk. For a high current starter draw electrically this is much different than a high current connection directly at the battery posts. Also, you would not jump from the BMW by directly going to the battery posts in the trunk with the vehicle still connected. Here again there is a possibility of over volting the BMW in providing high starting current. And after the dead vehicle starts, what the alternator outputs. Also, and what happens to system voltage when you disconnect the jumped from (source battery) cables. So, obviously a BMW with under hood terminals is not a suitable vehicle to provide a jump.
Really the best thing to do depends on the state of the dead battery. Obviously, the vehicle with the dead battery will not crank (start). So, the battery is basically dead. However, the battery may also be damaged, that is, has a bad cell. A little bit of analysis is probably the best starting point. For example use a DMM to measure the powered down voltage of the dead vehicle at the jump start posts (vehicle key off) and if the voltage is 11.5V or higher there is no real concern about a shorted cell. Then, ideally you would use a smart charger/power supply (no reverse current) match voltage, connected to the under hood posts and ramp up the voltage slowly until you flow about 0.1 C (10% of the battery capacity) current (e.g. a 100Ah battery = 100 C, so 0.1 C = 10 Amps) and observe how quickly the battery takes a charge while limiting the voltage at the under hood terminals to about 14.0 volts.
You would then charge the dead battery from the underhood posts in this way for about 30 minutes while maintaining the 0.1 C current rate making sure to limit the maximum voltage to 14.0 Volts. After about 30 minutes, ramp down the charger/power supply until the dead battery stops drawing current and disconnect from the under hood posts. Then try and crank the dead vehicle.
If you jump from a running vehicle, or connect when the vehicle is off and then start the vehicle, the car's alternator/regulator and control electronics will try and compenstate for the added load (dead vehicle battery) while running. This may potentially over volt the BMW depending on the jumped from vehicles electrical design. For example, the alternator may be commanded, based on the added load of the dead battery, to increase the output voltage to beyond 16 Volts (which would over volt the BMW with an AGM battery).
So, I think you can see the potential problem when introducing the operation of an alternator when both vehicles are jumped. We do not know what the alternator behavior will be when the vehicle is started (alternator output effecting the jumped from vehicle), or what the dead battery alternator output will do when disconnecting the jumper cables, sudden change in load.
The only real safe option, if the battery does not have a bad cell and is not frozed, is to essentially try and do a rapid controlled charge of 0.1 C (0.2 C rate max) for 30 to 60 minutes. Disconnect the charger and see if the dead battery vehicle will now start. In this way you eliminate an alternator high voltage output by compensating for the unusual high load, and there is no system voltage disruption (overvoltage spike) when disconnecting the source battery.
Using the points in the engine bay for maintentaing the batteries when the car is not used, could cause any issues?
You are weakening the charging because of the cable run to the battery. Always charge the battery not the car.
E39 530D Tried once. Confirm blown module after jump starting from the battery. NOTE: the old-fashioned big 12v lead acid jumpstarters are 12.8v ish checked my new 12v lithium/ion jumpstarter 17.6v hence the voltage spike. Lesson learned🙁
95% sure I will have to jump start my e90 325d when I get back, it will have been just over 7 months by then 😅 Luckily for my job I have a battery pack jump starter like this, slightly bigger and was banking on just using that.
Too late🤦 I've just fried something. No idea what though😭
@@nomblanko1 😜😂
Replaced the Battery and now I get a low buzzing noise when I turn off the E60 that now won't go away. Error code Supply Terminal 30E don't know if I messed up the IBS by jumping the car the wrong way before I replaced the battery. Any advice thanks
Thank you so much for this video! You probably just save me a massive repair bill
"German Engineers are clever"? My arse!
I disconnected the battery to replace it with a new one. Guess what, the fxxking FRM3 module went dead! Powered windows stopped working, none of the lights inside the car works, no turn signals. The car is pretty much not safe to drive anymore. Who would have though that disconnecting batter could damage the FRM3 module! Also, people said jump starting the car can also damage your FRM3 module.
BMW knew that they screwed up. If yours is damanged within 8 yr/125K, just go to the stealer to have it replaced for free. If you are over that, you will have to pay someone on ebay to reflash. Buying a new or used module will need coding. What a pain in the butt :)
So any Vehicle with under bonnet Battery hookups is best jumped from there and not from the Battery itself ? Another point is you keep mentioning BMW ONLY put the Battery in the Boot to keep it from Jump crazzies but I also see there is no room under the Bonnet to site the Battery anyway so I assume 2 reasons it's in the Boot. I use a NOCO GB150 and hopefully 3 years on you've now got a NOCO in your mits ?
I think i messed up my car because I needed a jump today and now my windows can’t go up. What should I do?!
BMWs can be jump started only if done according to the mannual instructions, only jump starting connectors in the bonnect should be used, connect positive cables first then negative, all consumables should be switched OFF on both cars. Start donor vehicle and let it run for at least 8 minutes then start the dead car, let both vehicles iddle for few minutes then remove negative terminals then positive. You will be fine if done this way.
Thanks for the insight. I’ve got an N55. I can’t imagine it’s much different. I’ll cross reference the OM to be sure.
AAA guy did that to my car and fried the shit out of it. wish I watched this earlier.
A Triple-I guy did the same thing to mine also although it did start after that but I'm wondering if that might be why I'm having some issues now. Good luck sorry to hear that that sucks....
does this almost never happens on an e46????
show the actual jump start to another can this way!
Listen bro I have bmw 2009 528i it's been parked 4 years .. two years ago I changed battery I had to tow it to shop and they replaced battery charged me 500
Now I used to start it time after time but today I need to move it and it battery is dead . Where can I buy that device what is the full name I really need help.. it is good battery it's just drains not completely but it can't start .. and I am afraid to jump it with other car.. at list what amp I it takes to start si I buy something that can set amp a on it.. I need help plz
Hi Dean I’ve jumped started my BMW from the battery now the driver and passenger windows don’t work Their in the anti lock You after keep pressing the button to get them up and down I’ve been told I have to put the car on diagnostics and turn them on In your opinion does this make sense Thanks Peter
I've seen hundreds of BMWs on the road that have been jump started, how do I know? The indicator relays must have been fried also.
😂😂 yep that’s the typical BMW driver
@@BMWDoctor my 2007 328i is showing power but not start
Are you using what he is using @CBG
Thanks for sharing. It would be prudent to simply follow ones Owners Manual to get the proper procedure for your specific vehicle.
My 2013 BMW X3 35i indicates jumping from another vehicle is ok to do, as long as the following procedure is followed correctly:
Preparation
:
1.Check whether the battery of the other vehicle has a voltage of 12 volts. This information
can be found on the battery.
2. Switch off the engine of the assisting vehicle.
3. Switch off any electronic systems/power
consumers in both vehicles.
Starting aid terminals:
Connect the jumper cables in the correct
order; otherwise, there is the danger of injury
from sparking
Connecting the cables
:
1. Pull off the cap of the BMW starting aid terminal.
2. Attach one terminal clamp of the positive
jumper cable to the positive terminal of the
battery, or to the corresponding starting
aid terminal of the vehicle providing assistance.
3. Attach the terminal clamp on the other end
of the cable to the positive terminal of the
battery, or to the corresponding starting
aid terminal of the vehicle to be started.
4. Attach one terminal clamp of the negative
jumper cable to the negative terminal of
the battery, or to the corresponding engine
or body ground of assisting vehicle.
5. Attach the second terminal clamp to the
negative terminal of the battery, or to the
corresponding engine or body ground of
the vehicle to be started.
Starting the engine
:
1. Start the engine of the assisting vehicle
and let it run for several minutes at an increased
idle speed.
2. Start the engine of the vehicle being
started in the usual way.
If the first starting attempt is not successful,
wait a few minutes before making another
attempt in order to allow the discharged
battery to recharge.
3. Let both engines run for several minutes.
4. Disconnect the jumper cables in the reverse
order.
Check the battery and recharge if necessary
Would this work for an X6? Thank you.
So that’s a cool video, but if the jumper I have doesn’t work maybe because it’s a poor jumper or bad battery how to you replace battery if you can get the trunk open. )2016 bmwz4 e89)?
Where can I buy this battery from?
Good time
Ihave Bmx6
It shows yellow car lift icon
And message say the battery increase discharge while stationary
Then after 2days it die
I replaced the battery but still the message and i con stay
After 7 days the new battery die
I take it to mechanic and who diAgnosis thy check recharger and all thing they suspect but no benefit
How you can fix this for me
For my 2015 BMW X3 xDrive F25 2.0 Diesel, I bought NOCO's Boost Plus GB40, along with it's Carrying Case. I also bought, for my Daughter's FIAT 500C another NOCO Boost Plus GB20 and Carrying Case.
Welp..RIP FRM. Guess I should have watched this before jumping the battery with a Dewalt Battery 😱
Thanks for that vital information Doc!!!!!
i have owned bmws since 1995, series 7, 3, 5, and x5 resently i drive a 2017 x5 is very nice, back in the days i used to work on them a lot but now since technology is so advanced all i do is oil change and breaks, right now my x5 battery i believe started acting out but i am not sure that is the issue, today i was very close to jump start it with my portable jumpper, but some how i did not and waited and when i tried, started right up but i very lazy and the gauge needles went up and down and then dropped and then went up staying on normal iddle possition, tomorrow i wil drive to bmw dealer i hope they dont rip me off, for all that saying i just want to thank you so much for such valuble tutorial because after so many years owned these cars did not know that would coause so much damages to modules, thank you for such a good info and taking your time to go down in details, you safe my wallet from drowning and save my money, i was very close to make the problem bigger, god bless you--
My bmw e90. Acts crazy. Mirrors turn backs or fall back wards .after I shutdown the car..???..don't ever know why
.
BMWs have had the battery in the boot or under the back seat since the '80s with corresponding terminals in the engine bay to start the car from a booster pack or another car.
First thing to do when jump starting ANY car is check the Owners Handbook. It will tell you how to jump start the car (if it can be jump started).
BMWs are not particularly sensitive to being jump started (no more than any modern car) but they do have to be jump started in the right way
Thanks for this video, I have a 320d e90 and will get one of these starter packs. Can I get one of the ones in halfords? I also have a battery charger which has a repair function. Can I use it on my car and if so would it be on these terminals under the bonnet that I connect to. Just thinking ahead for the cold winter were due.
Ya these boosters look great. Should pick up one for my E90 and Porsche 958. Have a lead acid one, but really big.
