- Uh oh...This 2011 BMW X5 Twin Turbo decided to not start in the owner's driveway.
Lots of codes set, and the Engine Computer is MIA. LOTS OF CODES!!
What is the most logical diagnostic approach? Will this be an expensive fix?

Jumper cables: $14
Figuring out where to put them: Priceless
Love it haha
Dealer: we'll need 8 hrs and $6k in parts to fix.
Ivan: hold my jumper cable.
Haha, hell yeah!
That's about the size of it ...
Sound's about, right
Must be the quickest bmw repair I have ever seen. Well done 👍
That will be 600.00 and ten for the strap
it's a BMW, the repairs are never done ;)
Everyone thinks it’s simple. Kudos to the guy who figured it out and posted this video let’s appreciate him because it is only simple because he showed you. If you were the ones diagnosing this problem y’all would have been pulling your own hair. So thank him I for one can’t thank this guy enough for sharing such video. Anyone can turn a wrench but there is only a handful like this guy.
3 years after your video, you were able to help me solve my no start issue on my F32 435i. THANK YOU SOOOOOO MUCH!!!!!!! 💪
Hell yeah, crank no start, codes galore, test light, jumper cables, and Russian. This one had it all. Thanks Ivan!
I had already pulled my wiring diagram and a note book to take some notes.. 🤣🤣
You know it's a BMW when Ivan starts sighing and never stops
Darn this one was TOO SIMPLE. I was hoping for some critters that had been feasting on those tasty wires since the car sat for a few weeks. Good job as always Ivan !!! 😄😄
I thought the same thing, a rodent issue.........
What kinda of sick fantasy is this :D
Scotty: "BMWs are endless money pits, look at how many codes it has!"
Ivan: "It has one bad wire."
LMAO yeah Scotty "all these computers are junk", Ivan "you just haven't a clue what you're doing and probably never did"
By the way.......my 2009 Honda CR-V had a similar problem and all it was, was a loose negative battery cable. The computer did find it......but that was too easy. In final desperation I tried to turn the cable, and it turned. I put on a new flat washer, a star washer and a new locking nut. Cleared all codes.....all problems went away! The computer went crazy with this untightened ground. Thanks....Jim
PS......This was last year at 115,000 miles....Jim
Still though, one bad wire to cause all those modules to not function?
I have no issue with BMW myself, but their engineers really should have gone further with the engine ground.
@@ReCkLeSsErr0r you would have thought that they would have used an insulated ground like most vehicles....Jim
Nice find!
Back in the day when the block grounds failed, seen many where starter current found its way back to ground through the accelerator or choke cables, melting their plastic sleeving and jamming the cable
yep, or other paths through fuel lines/clamps with rubber bushing worn, driveshaft/u-joints, shifter linkage/arms. you name it, the high current always wins :)
Great point
Sometimes quick and dirty is the best approach ,great video Ivan
Test light for the win
As mentioned, how and where to put the cable to bypass the ground is priceless. I couldn’t find my cables in the snowy box of my truck so I used one side off my booster pack and wedged it in the same spot by the oil filter and clamped to the cross member. -40 w/wind outside and the BMX started on 5 cranks. Thank You Ivan!
Ah, the importance of grounding straps...
I've relayed the saga of my fantastic 1993 C1500 before. She's old but solid. I will do just about anything to keep this simple, solid, and classic going. A couple of years ago I noticed the engine-to-frame-to-body grounding strap was near toast. I replaced both proactively to avoid the approaching odd electrical issues.
Then, while under the back, I noticed the static electricity grounding strap from the fuel filler neck to body was near dust. Replaced that too!
Good old eBay for the win on sourcing a small coil of tinned braided strapping!
Awesome. Almost no parts required. Great quick diagnosis. Thanks for sharing Ivan !
i did guess this one right for a change, yes i was prompted by that mad car last time.
Ivan I don't think anyone will forget that previous mad car lol.
That ground strap reminded me of the braded wire on a vw golf starter motor, green and falls apart in the hand.
not the only starters that used a braided wire from solenoid contacts into starter brush/field lol. seen many failed over the years.
Well done Ivan. Your experience and skill solves the puzzle. But I bet BMW wanted a small fortune for that ground strap.
it appears to be about $47 (12427565100) but if you have crimping tools you could make one for $20?
as a person who's been working on cars in new England since childhood my first diagnostic step has always been jumper cable grounds to battery chassis and engine. ive discovered a lot of misdiagnosed fuel pump failures that way.
Good point
Now I'd buy one of these with same symptoms only to find no compression!
Can you imagine buying one, immaculate condition except for the bad ground, for 2k?
You won't believe this but I had almost the exact same issue with a BMW SUV last week. The difference was that on the one I worked on the problem was the negative terminal on the battery which is mounted in the trunk with the spare tire. The customer said that when they attempted to start the motor the starter would spin but it wouldn't crank the motor over on the phone and I instructed them to jump the vehicle with another car to get it to me so that I could diagnose the issue. A previous owner had butchered the wiring to add a sound system so I suspected the problem was going to be in that area so that was my initial point of attack and had the repair completed in less than 15 minutes.
I think I will call Guinness book of world records: two BMW's fixed in less than a half hour and customer charged less than $500! I bet when you see these things come in you have a million causes going through your mind.
@@dogsplantscarsneatstuff176 That's funny
Another great diagnosis. I’m enjoying learning from you every time. Especially on this one since I drive an X5. If you ever have a valvetronic issue on the E70 X5’s, re run the reset function first before tearing into the intake to fix. Random but may help someone out there.
Another great diag Ivan! Great to have a photo at the end for added proof of what the problem was! It is amazing the issues that can come from on small little ground strap!
Great video Ivan, i wonder how many electrical problems on vehicles now days is a simple bad ground.Stay safe everyone.
Amazing diagnostic! Right to to the point! (that naked ground cable is kind of exposed to the elements I thinl the customer should buy a regular rubber covered ground cable)
Ivan you should ask BMW to put a test light module in since they have so few computers in their cars: with more computer modules comes more reliability! You must have 30M causes you are thinking about when looking at these cars.
never overlook he simple things. that is the lesson I got from this. Thanks Ivan!
This is why I am subscribed to you’re channel, you are good with software and you have really great common sense when looking at a problem.
I had a gut feeling that it was going to be a simple problem on this complex machine ;)
@@PineHollowAutoDiagnostics yes they sure have enough going on under the hood and dash lol, great job I really enjoy your videos.
I am experiencing this issue, i drove my x6 all yesterday no issues, i came home parked it and went outside to crank it no crank no start all dashlights on getting ibs codes and all kinda codes a559 a556 5f56 and i cant do nothing do u think same issue?
That was great. The simplest thing that can be overlooked. Great job as usual. Thanks for making these videos
Brilliant!! Test light is awesome 👏🏼!!!
In all the years as working as a tech I never thought to use a simple test light for engine ground verification. Always used a meter. I remember stories of missing engine grounds causing bearing failure on engines. Ivan I sent you an email on your website.
Thanks David!
Excellent video! Solved my problem! Never would have thought. This was als9 preventing alternator from charging battery properly.
I have no crank. No start. All Christmas tree. 2011 E70 , 162 k Kms. I will definitely check k the ground strap. It is definitely 12 years old and crusty rusted. Probably that is why no crank. It drove fine the day before and I parked it . Tried to start back up. No crank or start. Asked tow guy to boost the car. We tried to boost it from the engine bay. No lick. It started. After we boosted it from the battery. But the voltage 11.2 while the engine is running. That threw me off. Before I throw any part at it. The battery is brand new. I will check the ground strap. That could be the culprit. Thank u.
Some things never change; in the 60's, if the earth strap failed on a mini it melted the choke cable!
I'm going after my grounds now on my ram 1500! Wish me luck! Great Mind Ivan, you prove it over and over again!
Nothing beats experience.
Great ghost Mr Spock, who are you going to call. Ground Busters! Great work, Ivan.
For a moment, I thought this BMW is related to that AURA.
Here we go, 12 days of BMW!!!
Good training vid.
Stick with the basics first I always say but sometimes we get intimidated by all the messages and codes. Great job!
Great job. You are so good with your diag, you make it look so easy.
Had that exact same problem on a 2012 Bmw. I think it was a 528xi if I recall (it was back in may 2021). It was the first time I had a bad main ground problem like that so it took me a while to figure it out. (4 or 5 hours I think). I carry jumper cables In my diagnostic tool bag ever since for just that reason now. Lol! I remember what was frustrating about it at the time was that all data had no wiring diagrams for the car, or any decent service information for the one code it had in the DME. In fact, the snap on scan tool I was using had a useless code description too, and identifix had nothing to offer for the code. I remember thinking how I’m diagnosing a pretty complex car with a no start and more than a fee peculiar symptoms, but I was diagnosing it straight old school. I’ll always remember that one and how thrilled I was when I figured it out. Ground strap was even in the exact same condition and I pulled on it and it broke away!👍
Short video with amazing content! Thanks yet again Mr. Ivan!
It worked on my 2010 X5 e70 as well…. Jumper cable worked
Thanks… you are a lifesaver😎
Nice to see your father and brother ! (Not Ivan's Dad! My mistake.)
5:28
That was my brother, but not my Dad. My dad is too smart to buy a BMW...has a Honda and a Lexus ;)
@@PineHollowAutoDiagnostics Good point !
The problem lies not with this car but with Ivan. BMW sells these cars not as vehicles but as annuities for auto dealerships. After purchasing the vehicle, the owner provides the dealership with a guaranteed stream of income which is euphemistically called "repairs".
This guy is really something else . Thank u. I am going to check the ground . I had mine towed no crank no start. I will use the jumping cable as shown in the video.
Ready to busy out some parts cannon. But you got it licked by 2 minutes of diagnosis! Boom it works lol. Too easy of a job. You need really really tough job to keep you challenged!!! Haha
That was after 1 hour of banging my head against the wall xD
I was thinking rodent damage to a ground before watching the video.
I always look forward to the bonus footage. :)
Nice one! 👍 i thought it would be water intrusion
Awesome find Ivan!
Common problem with BMWs and Chevrolet Express vans...Braided exposed ground strap in the rust belts...what a brilliant idea !!
Dozen times, first thing to check in the salt belt.
You the man , I have had this before , normally make up a new earth cable and attached it some where easy to get to, near the alternator. Nissan's in the UK if battery 🔋 is very low will give many many ghost codes
And general new battery will sort it .
Until you did the bypass ground I was thinking rodent damage to some wires.
That was my first thought too.
I was expecting a shorted CAN bus, like the one that Eric O traced to a cable under the carpet on a Dodge Van...
Sat 2 weeks in the frozen north? Definitely mouse damage... what? Maybe a mouse peed on that strap!
Flawless victory !
Cool what a diagnosis. Stop and think is the lesson here. Great job!!!!
Super fix...Just got driving for a national auction company here in central Florida for a week...About 95% of all BMW'S and Mercedes had potentially expensive electronic repair problems...Let the Buyer Beware...
The auction is THE best place to practice diagnostic skills on tough case studies :)
Love Your comments in Russian. YOUR EXPERIENCES AND DIAGNSICS APROCH ARE AWESOME. May be refreshing of ground connections should be a part of annual maintanace?
I hope this is the problem with mine. Cluster blacked out few days ago. Parked it for 2 week and now no start. Thanks for the great video!
Ваня, привет from midwest, your videos just as always amazing, electronics 101 - Russian power lol. My dad is not a Auto mechanic but electronics engineer. He always is saying no matter what check the ground first and then p supply... it is amazing to me how much ground issues could cause. One time, I heard from old mechanic that bad ground could cause for antifreeze to brake down and cause gassing in expencion tank that looks like blown head gasket.
Funny I remember an old school saying Grounds Ground the world round. Working in the field I ran across more high scale open grounds the I can count. LOL
What a valuable lesson and one to remember for a very long time, Thank u very much.
Thank you for the excellent diagnosis. when my 2011 X5 N55 no crank and no start. e what. As the suv was running fine until one day.
I came across your video and decided to look for poor ground.,?
Yes that was exactly the issue with me suv. Thank you . Took out the rusted and bad ground cable. Do you self this favour change this part$48 that can leave you stranded. For sure all owners should make this to be a maintenance item. Pls check it.
Thank you 😊 bless you . Merry Xmas and a happy prosperous new year.
Another great video!! Simple things is the most head screshing , headed.ivan makes is look easy
This condition is worsened by warm engine....viz, it wont start with warm/hot engine...you'll have to wait for it to cool off...thank you man...was about to sell mine
Sweet -fixed with a jumper cable! 😁
That ground strap was SMOKED! I’d have left the jumper cable on to save some time and money… 🤣
Well done Ivan.
Well done Ivan, that could have led you up the garden path. 👍👍👍
Hey Ivan,happy New Year,heard ''sat for awhile'',thought green ground,ya nailed it,as you do, cheers,best to you and Amanda in the new year,take care!
Great Video! I can only imagine what BMW charged him for the ground strap...
$80 for that ground strap at my bmw dealer 😆😆😆😆😆 I just bought a AC Delco ground strap on Amazon for $12 same length perfect fit and no more electrical issues on my 08 528xi.
I was wrong! I guessed water in the DME.
2011 X5 35i. Same exact symptoms. Used a test light on same points. But getting a strong light. Tried jumper cables in same spot. Mine bolt on the oil cooler is a bit rusty. But got some signs of life now. Tried to start. Got a click. Still no start. Battery is brand new. Looked at ground strap. See all the same greenys. Must be the ground! Going to replace it anyway. I think they’re like $8!
good find.
I have resorted to that test first, any time a vehicle comes in with a NCNS
Wranglers are notorious!
Diagnose Dan had a similar issue with a 3-series. Turned out to be a wire shorting to ground via the exhaust, courtesy of a torn wiring harness.
I travel on Interstate s NY to Florida every month for 10 years.
These are the cars I see stuck on hwy:
1:Jeeps/ Chrysler
2: BMW
3:Audi vw
4: Benz
5: Various American brands that outnumber Euro trash by 10x nationally.
Usually GM Ford older models is a fuel pump or belt pulley high miles cheap to fix .
Get a Skoda over here
Skoda and Seat are both also VAG (VW) just a different design.
@@blockbertus oh ..I meant old CZ cars made well like Swedish Volvo's.
@@MitzvosGolem1 Oh, I see. Yeah, that's true. Or just get a real Volvo. ;-)
My opinion:
The newer the car (regardless the manufacturer), the more problems there are. And the harder it gets for the DIYer to do stuff on their own.
Having this information and knowing what is bad, next time carry parts and sell them at a premium price on the road 😅
@@blockbertus most American cars cheap to fix compared to Euro.Mid 2000s GM easy cheap to fix used parts all over. I have a bunch of GM trucks gas powered all over 200k miles not many issues.
I have the 3 million mile Volvo near me on Long island NY.
I liked the old 240 4cylinder manual transmission from 70s best..
Now a cult car especially Volvo wagons..
Soon all will be electric cars and batteries will be the issue .
Shalom
Sometimes the smartest fixes are the simplest ones. No parts cannon here, just a pop gun.
Dang. Perfectly running car, parked in the grass for a few weeks and then won't start? I went right to rodent damage.
THANK YOU!!!!!!! You fix it!!!(2014 X6)
Dealer: car is totaled, buy a new one.
Ivan: No parts required.
BMW, or any other German car are wonderful to drive.
But owning one, well, that's another story. I probably would have gone with a non-braided ground cable. Those braided straps are troublesome. And, don't forget to breakout the "sheep dip!"
Ivan gets all the bad grounds.... Not fair!
Had the same problem on an E87. Occasional non start. Badly corroded ground strap from engine to chassis rail.
USUALLY IVAN,that STRAP is yellow in color ,made out of thick nylon,AND IS ATTACHED TO A TOW TRUCK>haha good fix
LMAO!
bad ass mechanic love this guy !!!
Had same problem on a VW passat recently
Best part about this, nobody else prior had their hands on it, throwing parts at it.
Owner made a smart decision on who gets first stab at it. I'll assume that anyway.
All's well that ends well.
I wouldn't have trusted cranking and running it with jumper cables to random location on the engine to body, for fear of it spiking with big back emf pulse or other surge and blow something up.
the relays clicking and things going live would have been plenty enough to go and fix grounds back properly.
THANKS FOR YOUR VIDEO. because of this video i fixed my car with 13 dollars ground cable. THANK YOU
If you have so many codes on BMW, that usually means battery problems (low voltage). That the start. Sort out battery and then chase the faults. In this case ground, but the starter sounded like was struggling a little on the beginning.
When I saw the beginning with all the codes, I thought its time to check for rodent chewed wires!
I can’t believe that BMW is still using a old fashioned style uninsulated ground strap. Is this used by all mfg? Does Japan use this? Great analysis! Thanks....Jim
Hoovie bought one of these. It needed 4 new cats. Just drove it to the junkyard. Car Wizard -car to avoid. Scotty Kilmer: "Endless Money Pit".
My first inclination was rodent damage. Cars like to be indoors. I remember the Lexus from a few years ago. Lady went away...left car out. ....I think chewed wires to the trans.
Shifter was communicating via Morse code. Neeeeeeed Input Stephanie.
Yeah, why they use that type of engine earth strap is beyond me. I would have thought they would have moved away from them long ago, there are insulated round one they could fit these day, so why persist with them?
Great question haha
Very clever only experience will do
A Beamer would not be a Beamer without at least 20 fault codes.
at least 50
Yeah I found out my starter cable runs all the way in the back
trunk connecting to the Terminal Distribution Fuse Junction Plate
and that's why my suv wouldn't start. I tested all the positive cables and found out one wasn't
hot which was the starter cable.
First thing to check on BMW , power and ground.
Nice - there's a reason they say to start with the simple checks! So, how to prevent this sort of thing? The braid looked completely unprotected - I would think plastic sheathing over the strap and dielectric grease on the connections (only on the outside) would be a good idea.
Dealer would have put 2 ECM's in it before sending it to another shop.
