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 !

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 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)

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.

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.

[ImTMPZv]

Very very well informed video. Clearly presented and too the point. Spot on fella.

[stephenbarton]

Thank you so much for this video! You probably just save me a massive repair bill

[toddlls]

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 🙏

[zoehaze]

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!!!

[JEtt]

This is invaluable information! I knew never not to jump start a BMW but wasn’t sure how. I’ll get getting one if these chargers. Thank you!!!

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.

[ssaafur]

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.

[andyferguson]

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 🙏👍

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.

Great video. If you have a battery tester do carry out the tester at the same points in under the bonnet.

[easysolutionsglosuk]

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?

[markhurlin]

Another great video as always I’ve learnt so much watching your Chanel would you recommend this for a f11 2.0 diesel cheers

[lukecarter]

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.

[hedgehog]

Brilliant. I have a BMW 118d M-Sport and I didn't use it for 3 months. When I tried starting it I had a flat battery. Inadvertently, I attached my battery charger directly to the battery terminals in the boot. All I got when trying to start the car was a load of clicking noises and error messages on the dash. So I found your video then went to Halfords and bought one of these Lithium Jump Starters and followed your instructions. Car started first time! Luckily I didn't fry the car all the faults cleared and the car is running sweet. Thank you!

Knowledge is a wonderful thing. Thank you for sharing.
