This is one of the main reasons I LOVE the pico. Their method of recording over a long time base and being able to zoom in afterwards is much better than snapons backward thinking. No need to judge what time base is best before taking a capture.
Love it. When i am doing this i like to throw in a 3rd channel on the start signal. Then i know exact time from crank to ignition event and see the amplitude from the ckp at that point. A note on this test is that this problem is more inherent with vrs sensors. If the ckp is a hall sensor i go straight to fuel pressure for bleed back. Great video as usual
From the 'ridiculously low' 0.1 V p-p to 2 V p-p from the crank sensor was a great diagnosis... I had a similar experience with an infra-red sensor on a 5.1 sound system amplifier where the remote control would not work; the remote control was transmitting, but the sensor (with a 12 Volt DC reverse bias) was also a 'ridiculously low' 0.1 V p-p. Could not find a replacement, but aware that it was an infra-red receiver, used one from a 'trashed' video, giving a 5V p-p on the (cathode ray) oscilloscope... Fixed...
I believe the delta is time not voltage. You should have mentioned that you already checked for fuel pressure, long crank is most of the time low fuel pressure and the whole time I was wondering why your jumping on a crank sensor then I seen the FP gauge nice video
+JOHN HUFNAGEL See @2:00 we had a CKP code stored, so that was my first direction. Didn't need to check for fuel pressure...they rigged that gauge up before I got there. No easy schrader valve either, so that would be a last-resort test in terms of speed. Thanks for the comments, John!
Is there any other source for the information that you normally get with the snap on Vantage, verus or any other snap on tools that are/have an oscilloscope? The information I'm referring to is where they state which pin to backprobe, show a sample waveform, etc. 6:38 is an example in your video.
AllData, Mitchell, IDFix are the main paid info sources. BBBIndustries is a free resource for wiring diagrams, but they are often skimpy on the Euro info )
motoYam82 I had an E36 325i and I learned a ton on that car. It would tell you which headlight, taillight or blinker light was out and it also showed faults for the trunk wiring on the OBC. I had to spliced most of the wires back together in the trunk loom where they flex from opening and closing the lid. Then there was other run of the mill stuff with vanos seals, cooling system etc.. The E46 I have now is an improvement on the E36, but there is more plastic. And I also had a bad crank sensor on the E36 and a bad coil on the E46 so far, but nothing major.
Hi Ivan, my Passat CC 2012 is having an issue of crank, no start sometimes, when it is able to start up, it comes out intermittent error lights and warnings, sent to my local VW workshop, it diagnosed that car has no communication with the instrument cluster and that has to be changed out. They quote me a whopping 5 grand for that job. Was wondering if I am able to find the cluster myself and get someone else to program it? A concern is that none of my local workshops know how to program that. Any advice you can give me please?
I’m 20 years old trying to learn about diagnostics. What exactly was the issues with this car what was causing the long crank and what were you doing with the scanner to fix the issue?
Not sure why you hate that much the European cars and Europe as all, but saying on some videos "Russian Repair" And still good job, pleasure watching you. Not anyone can afford bmw after all. Most people that give bad grades for cars, drive second hand cars all their lives! I have model e46 new from the very beginning, never ever happened to it except for mass airflow sensor, one oxigen sensor and some trifles on the running gear. This is awesome brand! Thank you.
Wish I could pay you to come and fix my vehicle. Its been to 4 shops, 6 weeks later and no one has fixed it. Thousands later still the same problem :( ☹
my x5 crank but not start, there was no pressure on the fuel inyection system, but it has fire on the sparks, so I just connect a cable at the pump´s positive to the rear fuse box, and it started, but can't find the failure, any ideas?
Do you work in the parking lot due to insurance reasons? Basically not being allowed in the shop cause your not a employee? Been curious for a while. I am a 15yr veteran master tech in the import world. Want to say the I have actually learned a couple of methods that are easier than how I was doing it and I do appreciate the videos. Had my not tech friend watch it and he mentioned that he would like to see you explain your measurements in a little more detail. That way I dont get 10 phone calls every time we watches a videos...lol keep up the great work. You are in the 1% Like me that just love diagnosing
Also do you just use your vantage ultra as a dvom or do you have one that you use for quick measurements. Considering trading in my fluke towards the vantage. Just not sure about not having a normal dvom
Great video Ivan like your attention to detail. I noticed your fuel pressure gauge in video what brand? How does it do on most German and Asian cars? Does BMW have a fuel pressure test port? Thanks. Mark ferraro
yo! moto! i just subed for that ACURA... i missed that kind of case studies,,, keep my sub in good condition dont let me down heheh just kidding :) .. love the acura case,, love it
You know, for about $2 they could add four analog sampling ports from 64 inputs, brought out to 4 scope channels. For another $3, they could add a scope built into the media display. How cool would that be? Even better, they could have the engine computer monitor those channels and at least partially narrow the probem down to a few invalid looking signals. Why doesn't every car have this already?
This is true what why would a manufacturer care about making it easy for a DIYer to fix their car. Some old Cadilacs had a way of button pressing on the HVAC panel that allowed you to get codes, data, and even bi-directional control. It was only for a few years then management probably thought it was more bother than it's worth having end users being able to try to diagnose their own car and cut the dealer out.
This video should of never been more than 5 minutes long. After watching for 30 minutes its obvious that you have never encountered or detected anything like this before or you were still figuring out your recently acquired hardware/software. I do appreciate you sharing anyway.I now know what to look for. Thank you.
Seems the VERUS is the more versatile reader, that works on more vehicles and has deeper depth of readings and information. Why bother with the LAUNCH system?
The Verus is a more well-rounded tool, since it has a scope and info database built in. The Launch generally has more coverage of specific OEM functions, especially on newer and Euro vehicles. There is no perfect scanner.
BTW - To all supporters and non-supporters alike. Please watch some of the pre-vid ads. They really do help to keep the channels alive. Better yet click the donate button. Please every donation makes a huge difference! lot!
motoYam82 They did make "X5M" models, but starting with the next generation E70 body. These E53s were limited to 4.6is and 4.8is as the sporty variants, with more issues than you could shake a stick at, beginning with failure prone air suspensions and ending god knows where! This one is obviously an imposter.
Maybe its not right dont you think, everywhere a system more complex becomes more problems gonna come out, the europeans use lets say a 4 liter naturally aspirated engine (ferrari 458 italia) and produce 605 hp, in the united stater you have to use a 7 liter engine to obtain that power, because you dont tend to use such a complexed systems, maybe this is the reason you call'em garbage 😀😀
No, its because it is actually garbage. I can build a better looking harness than that. Come on BMW, at least use different color wires so when one of these "amazing" systems fail they will be easier to diagnose. Can't be "the ultimate driving machine" if you cant even get it out of the parking lot. Also it takes us 7 liters to get that kind of horse power but with 5x the torque ;)
hi im gonna say something please dont take it the wrong way i like how your doing work on these machines but i see this everyday and every tech does this mistake you just did theres absolutly nothing wrong withe the crank sensor a sensor goes bad if the diode it broken or overheated it works or it doesent you have a gunk problem an engin flush will fix this problem and other problems it starts dificult in the morning cause the gunk has solidified in the morning and as it heats up it flows on unblockes the sulface area of the sensor as it cools down it builds up and solidifies the gunk in front of the sensor you dig you understand
This is one of the main reasons I LOVE the pico. Their method of recording over a long time base and being able to zoom in afterwards is much better than snapons backward thinking. No need to judge what time base is best before taking a capture.
Awesome diagnosis and repair.

Nice diagnostics on the crank sensor Ivan and good work on the details of explanation.
Thanks Ivan, I love to see BMW X5 ,very powerful car.
Yeah, I pass them all the time with my 94 F150, broke down on the side of the highway with their hood open, and their owners staring at the engine.
very interesting fix, nice work, good Thank you
I had something to do with building that X5. It was made in Greer SC.
That lead in picture with all the pretty wires, and the green weenie pin plugs looks like a mouse buffet in the making.
From the 'ridiculously low' 0.1 V p-p to 2 V p-p from the crank sensor was a great diagnosis...

There you go ivan good work.
very good job ivan
Anybody else find it hilarious that the place Ivan used to work called him back to fix a vehicle they couldn't? 😂😂😂😂
genus work
Nice fix and good testing
Well done
That was some awesome testing. Lots of stress on that one with a garage called Absolute Auto Repair :)
14:50 all of a sudden a weed eater leaf blower shows up ? Small engine repairs too...
Steve Rob The quickest way to clean a car interior...tricks of the trade!
Eh! Ivan have same issue on my 97 olds 3.8 have new crank sensor just need to have it installed one day hahaha good show
Sal
your earthing point is right in front of your positive feed. its on the suspension top mount. 😀
Good video

motoYam82 thank you. yes i subscribe to alldata but im looking more for the info you see wherr they pretty much tell you where to stick your probe
Great video!
Good job on the X5. BMW's aren't too bad you just have to get the used to their technology.
bimmerman3 I'm a fan of their older vehicles, early 90s and before. Lots of character, solid engineering...and less plastic haha

"These cars are all plastic!" Classic.
We used Break out boxes at the BMW/MINI dealer. no back probing. but if you need to you can slide the thin connector out of the pack.
+Kurt Kennedy Yeah once the plastic connector cover was off, the pins were quite easy to back-probe on this Beemer
+motoYam82 Protip: Beamers are BMW motorcycles. Bimmers are BMW cars.
How do you figure that?
I’m 20 years old trying to learn about diagnostics. What exactly was the issues with this car what was causing the long crank and what were you doing with the scanner to fix the issue?
my instinct would be swap the sensor first because it is cheaper than an hr of diagnostics
True. But what if that's NOT the problem...who pays for the sensor and labor?
Derek Simenac temp sensor that is!!
How to say I'm a parts cannon cowboy, ot a technician. Without saying it
Not sure why you hate that much the European cars and Europe as all, but saying on some videos "Russian Repair"
And still good job, pleasure watching you.

Sweet.
I'm having a long crank issue and smelling gas but dont start. Any ideas that can help me out
Did you ever find the solution? Mine does that once ina while
Wish I could pay you to come and fix my vehicle. Its been to 4 shops, 6 weeks later and no one has fixed it. Thousands later still the same problem :( ☹

Did u solve????
Wiring
nice video, where is located the crank sensor?
Bell housing
I linked your video to a X5 forum that I am a member.
+Upallnight Nice!
Sure, another great diagnostics as always, but why due to the dude, its because of you, you chose to go there.

+Mark Ferraro Wasn't my gauge...the shop was messing with it before I got there.
motoYam82 you diagnosing the leaf blower that is laying on the ground lol
yo! moto! i just subed for that ACURA... i missed that kind of case studies,,, keep my sub in good condition dont let me down heheh just kidding :) .. love the acura case,, love it
+serchmarc I'll do my best serchmarc...lots of good case studies to come! Yeah the Acura kicked my ass pretty hard lol no pain no gain!
When testing a AC sensor rule of thumb you need 300 mil volt to start the car
+Stephen Kasapis Hi Stephen, did you watch my Acura no-start case study yet? That is a great example of how weak is too weak...

BMW = Bring More Wrenches, but great diag!
Great video! Euro cars is nice, but BMW loves plastic :)
First guess would be fuel problem
The ground is right in front of you on the strut tower. Sometimes things are too easy I guess. By the way that is a bogus M sport.
How much do you charge for your troubleshooting and by chance are you in Houston Texas
Hi Perla, I'm located in Pennsylvania. Look up Scotty Kilmer in Texas, I think he is in the Houston area.
Pine Hollow Auto Diagnostics rev up your engines. Lol hahaha
It's always funny to see that Americans love USA cars and hate Euro's and vice versa, lol.

Old video but yeah you need a $5000 scope to make sense of this. Not for the average DIY.
Mine cost about 100 quids. It's cheap but shows enough to see most problems.
I really great job with your diag and repair verification video. Most people won't even touch a BMW=(BIG Money Wasted)
Americans complain about European cars that they are made off plastic!🤣🤣🤣🤣🤣🤣
Are you helping people fix things? Or showing off your scan tool? This video could have been under 5 min
This was 8 years ago... I was a UA-cam noob 😂
You oughta stop whining about European cars.
all those cars are such garbage!
Maybe its not right dont you think, everywhere a system more complex becomes more problems gonna come out, the europeans use lets say a 4 liter naturally aspirated engine (ferrari 458 italia) and produce 605 hp, in the united stater you have to use a 7 liter engine to obtain that power, because you dont tend to use such a complexed systems, maybe this is the reason you call'em garbage 😀😀

Can't be "the ultimate driving machine" if you cant even get it out of the parking lot.
Also it takes us 7 liters to get that kind of horse power but with 5x the torque ;)
hi im gonna say something please dont take it the wrong way i like how your doing work on these machines
but i see this everyday and every tech does this mistake you just did
theres absolutly nothing wrong withe the crank sensor a sensor goes bad if the diode it broken or overheated it works or it doesent
you have a gunk problem an engin flush will fix this problem and other problems
it starts dificult in the morning cause the gunk has solidified in the morning and as it heats up it flows on unblockes the sulface area of the sensor as it cools down it builds up and solidifies the gunk in front of the sensor you dig you understand
