DEF System Case Study: BMW X5 Diesel - Part 1

[@citycafe291267]

You are the best guy on all internet to explain car problems! thank you

[@nicknicu1787]

I like it Ivan! Props to you for digging into this! I see too many technicians complaining " this is an over-engineered expensive car " and they don't have the willingness to learn something new. That is a really sweet car to drive when everything works. Most of the " complications " built into these cars are triggered by strict emissions. I'm looking forward to part 2! 👍

[@PineHollowAutoDiagnostics]

I will say that it did drive really nicely and according to the owner it easily gets over 30mpg...

[@ej2659]

Imagine the MPG's and performance without the DEF. In Pa. we do not have emissions on diesels but I'm sure the CEL etc. would be on if it was deleted.

[@throttlebottle5906]

Quote: "That is a really sweet car to drive when everything works." to that I say, did it ever work right? seems to me they were plagued with issue from the factory :)

[@PineHollowAutoDiagnostics]

Not just CEL...it wouldn't even start or be in limp mode without the emissions stuff working as it should.

[@ToyotatechDK]

So very true

[@Peter_Riis_DK]

The spikes, at the 24 min. Mark, look like what you get, when you feed a square wave through a small capacitor - you actually see only the low to high, and high to low transitions. The upper trace looks to be subject to much the same, but through a larger capacitor ( the load being the same ) - bad connections sometimes act as capacitors. Well, don't know if it helps or it's too late, but now it's out there. Rooting for you, Ivan. 👍

[@simonparkinson1053]

Learning how it works as you go may mean the first one you work on takes some time, but that knowledge is with you forever - and we're learning too. DME (Digital Motor Electronics): The main computer for a gasoline engine. DDE (Digital Diesel Electronics): The main computer for a diesel engine. These have been the BMW names for the ECM since....forever. I believe the trans control has always had a separate module, rather than an all-in-one PCM. Last BMW Diesel I had was a '93 525tds. Smooth as silk, could stand a coin on edge on top of the valve cover with it idling - but a very strange torque curve for a Diesel. Not much below 2000rpm but would then just pull hard, until it hit the limiter, whereas most from that era had loads low down but ran out of breath at about 3500rpm. They put those engines in the Range Rover of that era too but weren't a good choice because of that torque curve.

[@baxrok2.]

Very cool. All of this GDI and diesel work has become pretty interesting. Thanks Ivan!

[@antoniomancini8738]

man you're awesome I enjoy these videos keep them coming very knowledgeable thumbs up

[@R.E.HILL_]

Excellent. Finally a real car. ☺ Thx for sharing.

[@gtemnykh]

Yeah, a real crappy car! :p

[@meab12]

Yeah, a real piece of shit!

[@danekeeper1]

Hey Ivan..I have this vehicle..the Def tanks get wonky when they are run dry or they are refilled.....next time drain the fluid and replace with warm water/ drain repeat.refill wil def fluid....don't let then get empty because the fluid will crystallize and ...blah blah blah. there is also an extended warranty up to 115,000 miles now for R and R of the tank(s)

[@darrellshinn5983]

[@crcdesign9886]

Hey! I meant to tell you if you remember me and my issue with the 09 BMW X5...it needed a transfer case control module. PLEASE keep up the wonderful amazing detailed videos Ivan!

[@PineHollowAutoDiagnostics]

Awesome! glad you got it figured out!

[@crcdesign9886]

My biggest cue, and you should note this, was the "ecu rejected" I received when trying to test the control motor.. I dismissed it as an Autel mishap but it wasn't. I doubt you'll ever come across this issue but if you do i have a lot of data and info to share. Thank you so much ,Ivan, for taking the time out of your busy schedule to communicate with me...It forced me to think and test which led to the proper diagnosis.

[@jimzivny1554]

Don't leave me!!! This is a very interesting video. First, my first twenty years of working I worked on medium and heavy trucks, mostly diesels, I love 'em, the older the better, the govt has gone crazy with control issues and not all good. Second, my son has a BMW 325 something and I've learned that as well as being a very well engineered and well performing car it's a very complicated machine and parts are insanely expensive. Given the complexity of the diesel engine controls(esp being a BMW) these days and the price of parts I would never buy another(gas or diesel) used that is beyond warranty limits. Here's a good example; my buddy has a 2003 325I E46 sedan, 170k, great clean car, the fuel pump went bad, you need to buy a complete tank assembly to replace a pump, the dealer quoted $2175.00 list but he would do me a favor since he had one in stock and let me have it for $1800.00!!! We rolled the dice with a junkyard tank which was still $400+ and he hasn't had any trouble for a few months. Looking forward to part two!

[@PineHollowAutoDiagnostics]

Wow replace the whole tank just because a fuel pump went bad?!? Haven't heard that one before...leave it to BMW haha

[@stevestacey5793]

Looks like it could be an ultrasonic level sensor where the yellow trace on the scope is the driving signal that generates a sound pulse and the other 2 signals are some kind of measured reflected sound from the other side of the tank. The speed of sound is probably faster in liquid than air, so when the tank is full most of the sound path is liquid and therefore the time delay between the sound pulse being generated and echoing back from the other side of the tank will be shorter than when it is empty. Couldn't see any obvious difference in the traces at the end, but would be interesting to overlay the 3 signals and compare the timings when it is measuring different fill levels

[@PineHollowAutoDiagnostics]

Bravo! This is the type of comment that deserves to be in some scientific paper...but wait, this is only an automotive repair channel! Truly thinking outside of the box! But you never know what solution those clever Germanengineers will come up with just to perform a seemingly simple task of measuring the the fluid level in a tank haha! Hopefully Part 2 will answer some questions :)

[@timothybarney7257]

With my limited exposure to ultrasonic level sensors, I gotta say I don't like them. We have several stationary diesels running standby generators and a few have ultrasonic fuel level gauges...we've had nothing but problems with them.

[@AJ67901]

Hey Ivan, I've been enjoying your channel for some time now. Your diagnostics really demonstrate just how much cars have changed. The days of the shade tree mechanic with a timing light and wrenches is long gone. Looking forward to the 2nd part of this vid. This 2011 BMW must have been among the first to employ the DEF/SCR exhaust system. I'm eager to see how it turns out. Thanks for the interesting videos.

[@PineHollowAutoDiagnostics]

Part 2 should be up tonight!

[@mcplutt]

I believe E70's had DEF as early as 2009 in USA. But not until 2014 in Europe (Euro6 emission), with the F15 chassis. My 2013 N57 30d (Euro5 emission) has no DEF system.

[@QueenCityHistory]

great video like always Ivan. honestly I did miss the beard!

[@paulmeehan1978]

Diesel ! excellent. keep them coming Ivan

[@AdrianKingsleyHughes]

"Man, this all sounds very expensive!" As a former BMW owner, let me be the first to say hahahahahahahahaha

[@GarthGoldberg]

And the reason he paid thousands extra for a diesel was to save money on fuel. hahahahahahahahaha

[@AutoFocus-se]

Good case Ivan. I did some digging. And found some info about the level sensors. In the Active tank its 3 sensors, High,Mid and Low. That's why your wiring diagram says that. The sensor uses the Conductivity of the fluid. Like a coolant level sensor. So, in theory, it can only show 3 values :) Waiting for next part. Cheers.

[@PineHollowAutoDiagnostics]

We will discuss this in Part 2 :)

[@MrBez09]

Now I know even us old timers use the term whatyamacallit it make me feel better when I hear Ivan use it

[@jonascourtney5999]

like that reminder "don't forget me "...wonder all stuff sometimes we forget...hum...what we are talking about ? Thank you for the video on this fine Bayerische Motoren Werke.

[@killer2600]

[@stigonutube]

Trip to the moon in my rocket anyone? Good Video Ivan..

[@int53185]

Great cars to drive, nightmares to repair.

[@tam1381]

Ivan i refuse to do any work on these X5,s. The auto sparks here dread looking at these things.However when we get to part 12 on this series it will all become clear. Goodluck.

[@PineHollowAutoDiagnostics]

One of the few cars that has stumped me was a BMW X5 V8 that was misfiring and shutting off cylinders for no apparent reason. I might post that case study sometime too...with no "happy ending" lol

[@tam1381]

Ivan if it stumped you what chance do the rest of us have.... However what i learn in watching you inspecting these jobs is invaluable. Keep up the awesome work.

[@Photostudioww]

Part 12 . Hahahaha

[@happy543210]

selling an old bmw is always a good idea...buying an old bmw is a nightmare waiting to happen!

[@PineHollowAutoDiagnostics]

This was more than two months ago...X5 is still sitting in his driveway xD

[@happy543210]

that's what bmw's are best at...driveway ornaments, lol!!

[@opl500]

Only way to drive German plastic is to lease it. Seriously, they are only designed to last long enough for one lease period and then they will start falling apart. And when they do, it's $$$ to keep them running.

[@mcplutt]

Fun Fact: Here in Europe the E70 diesels don't have a DEF system. At least my 2013 30d N57 doesn't have one (Euro5 emission). I am so happy about that.

[@johnmckamy6398]

Another day in paradise.

[@BigDog50001]

A Euro diesel repair, woo hoo!

[@PaulHigginbothamSr]

Tis either the connector or the def tank sensor. Since the fluid is urea I suspect sensor failure since urea in autos is not normal.

[@baddriversofnorthtexas6850]

when i see "part 1" i think awww. Some people will get confused this was recorded in march but you said that it was recently 65 degrees outside, which actually sounds like may, current month

[@Discretesignals]

make sure your scope is ground referenced at the neg battery post. don't rely on the sensor or module ground to be accurate. watch your sample rate at longer time bases. you may miss fast glitches because the data points are too far apart. for fast data such as ignition, position sensor, and data bus stay at 1 us or above. click view properties to view sample rate.

[@jacobusa4727]

didn't get notification? waiting for part 2 go get her done Ivan

[@dayntubee]

How do you like the launch x431 compare to autel mk906ts?

[@bangorsix1576]

Hi do more vids on this bmw x5 looking to buy one but i dont know much. How is the economy in diesel mpg? How much is to maintain? Are the air suspension really expensive ?

[@LAKERS4LIFE-g1i]

Hi why you got that sticker on your scan tool

[@zoidberg444]

02 seconds into the video... Oh no... Here we go 20 seconds into the video... Why on earth does the dude want to fix this turd 25 seconds into the video... Ah. This dude has some sense at least! 29 minutes into the video... Should have got a Lexus. 😂 Abandon all hope ye who enter here. Great case study Ivan.

[@PineHollowAutoDiagnostics]

The owner was so properly Euro, that his pants matched the interior of the BMW. Lexus just wouldn't do!

[@zoidberg444]

Your neighbor should think himself lucky. Our training manager has his BMW 750d die a few weeks ago. Just wouldn't start up or do anything. It was at the BMW dealers for 3 weeks. It cost him the best part of £4000 and it still isn't right.

[@PineHollowAutoDiagnostics]

So in his case the saying holds true: BMW=BIG MONEY WASTED lol

[@robertwillingham8037]

They decided to buy, don't feel bad about it being expensive to repair👍

[@BigDog50001]

I hate it when I run out of exhaust fluid....

[@imaniguana]

It reminded me of trouble shooting systems on the Shuttle Orbiter. . . . only more complicated.

[@valde3336]

Does the scan tool have option to show the fill levels in voltage? Or some other way than just percentage? If it does then looking at them could have helped to understand the system and the problem better from the start.

[@Mikton2509]

Enjoy your videos! What model pico do are you using? Thanks

[@JMassengill]

Could it be a ground problem of some type? The way that signal on your scanner was jumping around looks like an intermittent ground to me. Keep up the good work. Enjoy your videos.

[@PineHollowAutoDiagnostics]

It definitely doesn't look like a regular level sensor signal! That's because BMW lol

[@deepsquat600]

Watching you with the Pico scope over the last few months makes me want to buy one ...maybe just the cheapo ..dont even know what I woulnd do with it.. but I want one LOL

[@PineHollowAutoDiagnostics]

Yeah get the cheap 2-channel one! Then you will be probing every wire you can find...it's fun :)

[@deepsquat600]

LOL ..yeah thats what i was thinking 2 channel :) . .back probing ..too much can get you in trouble LOL :)

[@deepsquat600]

just ordered a Hantec 8 channel and some back probes ..watched a few videos on you tube ..seems like a winner..I will let you know how it does

[@PineHollowAutoDiagnostics]

Holy crap 8 channels?!? What do you use them all for? That's a lot of leads :)

[@deepsquat600]

easy ..eight channels..CNN HBO ESPN no wait wrong type of channel

[@volvo09]

he wants to sell it?, you mean the warranty ran out and he's going to go broke fixing it? haha.

[@lorrainehillman9200]

Will that Launch x431 be good for pre 2007 Mercedes Sprinters? I noticed the Sprinter listed under European vehicles. Thanks

[@triggrhaapi]

I have a similar issue on my 335D. As long as you keep the DEF tanks filled, the CEL goes away.

[@Bierkameel]

You should only buy this car with a Doug DeMuro "bumper to bumper warranty"

[@loayoweis]

The Active tank Reservoir has an extended 10 year 120kmi warranty not sure if this was known

[@asavage1576]

I work on trucks for a living. Yea aftertreatment gets very expensive. A lot of guys don't like troubleshooting it. I love if. Would rather donelectrical than change brakes and do suspension work haha

[@Krillekris]

Love to se you work and diagnose, it's so interesting. Do you sometimes use the Pico waveform library and find it useful? Thinking about getting a PicoScope Automotive, but it is much more expensive then similar Hantek Automotive scope.

[@PineHollowAutoDiagnostics]

I very seldom use the library, but it is useful for more common vehicles. Is the Hantek USB-based? I think you can get a 2-channel regular Pico for under $200 and just use attenuators if you are measuring anything with voltage spikes.

[@Krillekris]

Hantek is an USB oscilloscope. And you can get a really good one (automotive model) for 300 dollars (250MHz, 4channels, 1Gs). Hantek do also have nice probes, and are much cheaper then Pico. I do have a cheap Pico Scope, but i find it lacking in detail.

[@PineHollowAutoDiagnostics]

How is the Hantek software? User friendly? I find often that the software is the most frustrating aspect of the cheaper Chinese electronics. And what do you mean in "lacking in detail"? Like sample rate is too low?

[@Krillekris]

I bought the cheapest Pico I could get, a 2000 series 10Mhz and tried it with a signal generator. The graph was very coarse. A sinus wave looks more like hills with steps on them than a smooth curve. And there is no way you can filter it. It's not supported. Hantek Automotive version seems like a really user friendly scope, and you get almost top of the line for 300 dollars. If you are truly interested in knowing more about the Hantek option you can download their software and try it without scope. Here is a link: www.hantek.com/en/ProductDetail_13_10163.html I'm still doing research about the topic.

[@throttlebottle5906]

love it @ 13:42 almost fell off the chair laughing :))))

[@PaulHigginbothamSr]

You do know you need an old Galion road grader. Maybe not one of those massive ones but a big one.

[@sjair6526]

I don't understand how the level sensor works! Is it 3 different pins at different levels in the tank with each pin getting a voltage pulse? Thats the only thing that makes sense to me and that might be why the low sensor is different because the level is between the mid and low sensor and the low level sensor is the only pin covered in fluid. That would still make the levels detectable at 33%, 66%, and 99%. I guess the pins could be at other levels than thirds. But how does it detect between levels? Is it learned or calculated from the ecm memory of DEF usage? I think you need a manual. It seems very complicated for level detection. Why not a float? Is the fluid corrosive or something?

[@PineHollowAutoDiagnostics]

"why not a float?"...I wish I could ask the BMW engineers that very question!

[@sjair6526]

Pine Hollow Auto Diagnostics, so I gotta know, is it looking for a certain capacitance on the def fluid or is it an ultrasonic sensor? The positive part of the waveform looks like a capacitor decay but the negative does not. I expect a full explanation of how this works in part 2! Ha! Just kidding :)

[@rrmech11]

very interesting

[@notyou6950]

There's a 50% chance I watched that vehicle get made. I used to work in the body shop where they make them. I have a fine memory of that place.

[@OffroadEthan]

I'm at 3:00 and I can tell you I see this all the time. Get your wallet out with this one. They all need a SCR tank after a certain amount of time if they have the old tank design. The active tank pump fails or the internal seal leaks on the passive tank and it gets expensive outside of warranty. I haven't seen one come through in quite awhile but there are still some out there with the old Bosch design I'm sure.

[@PineHollowAutoDiagnostics]

No pump failures on this one...yet.

[@steverice5211]

Ethan BMW warranties this part now to over 100000 miles and will reimburse you if you paid to have it done already

[@yovanichavez1354]

Good

[@willemstreutgers1154]

Isn't the X5 build in the USA ? !

[@wyattoneable]

The ending came too quickly but I'll b e back for part two!

[@PineHollowAutoDiagnostics]

I was just hoping it wasn't too boring for most viewers! Had to cut out like 15 minutes of experiments that didn't really go anywhere...

[@joelmccoin9727]

Hello Ivan. My Grandmother used to say to me "What have we learned from this" What I have learned is "Don't Buy a BMW"

[@PineHollowAutoDiagnostics]

You get an A+ :)

[@IBenZik]

Why in the world would you have a def tank fill hole under the hood of the car

[@chrismechanic2000]

i have never been a diesel engine car fan, even 20 years ago, these days i would not recomend anyone to buy one new or used. they are have gone to a new level of rediculous due to emmisions standards.

[@joerosaticollective]

there is a 10 year 120,000 mile warranty on that tank which needs to be replaced if the sensor fails, so BMW should replace it at no cost.. just had mine done

[@vikjts]

Yes, 2012 was done at 52k miles fully covered by BMW.

[@R.E.HILL_]

It would have been fun to see how you would manage to do a diagnosis with only the the help of a test light and an ELM327 bluetooth scanner.(and Torque app) And your brain, of course. ☺

[@PineHollowAutoDiagnostics]

Wouldn't get too far on this beast without at least seeing the DEF level in the tanks on a real scanner, and using an oscilloscope to watch the raw signals. Otherwise it would just be "read code, replace expensive part, pray that it works" procedure.

[@R.E.HILL_]

Sure.. I didn't necessarily mean on this car. To many modules. But having the ability to pull codes and using a test light is better than nothing...

[@PineHollowAutoDiagnostics]

Absolutely. You can diag about 90% of cars with an OBDII reader, a test light, DVOM, and access to some wiring diagrams :)

[@user-fl7nt4ck7b]

Man, you look younger without the beard.

[@tinkerwest]

This one is a candidate for cel bulb removal.... :)

[@ej2659]

The only thing that I can think of worse than buying a used BMW would be a used diesel BMW with DEF. My god that is just a shit show waiting to happen.

[@PineHollowAutoDiagnostics]

LOL Whenever I work on one of these things, I start feeling uneasy like something else is going to break any second and I will get blamed for it! Get it out of my shop ASAP!

[@ej2659]

I don't blame you. It only takes that happening once or twice till you just refuse to work on them. "I'd like to but the juice just isn't worth the squeeze, you should take it to the dealer". You just never know what other $2000 can of worms you are going to open up. As someone who started turning wrenches a couple decades ago it's just not worth it.

[@GarthGoldberg]

EJ don't mince your words. Tell us what you really think.

[@PineHollowAutoDiagnostics]

[@clintonandrews1538]

[@chadharmon5716]

Welcome to what used to be the best engines for fuel economy and reliability till the EPA emissions turned them into shit

[@PineHollowAutoDiagnostics]

I started this thing in a closed garage and didn't smell anything at all. Tail pipes were clean as a whistle too! And its a diesel!

[@zoidberg444]

I think the Euro 5 and Euro 6 emissions standards beat you to it. Europe is the main market for these turds, they sell so few of them in the states or Japan that it wouldn't be worth designing and selling a non emissions controlled version in the US.

[@leexgx]

We don't use the DEF tank in the uk/EU so this is not a problem (the DPF can be issue if it gets blocked up and fails to regen)

[@Photostudioww]

chad harmon hahahhahaha I have a 1996 vw TDI no def no EGR.

[@ozzstars_cars]

looks like a headache issue

[@bbogdanmircea]

you could piss in the tank, as it is working with urea ... These SCR systems are incredibly complicated, so you need really to know in detail what the signals should look like to be able to diagnose something. Doesn't the pick have library to process the signal and show the actual duty cycle

[@PineHollowAutoDiagnostics]

Yeah this was my first real experience with an SCR system, so we are all learning together. But with a scope and some hints and common sense, we will be able to get a pretty accurate picture of what the signals should look like.

[@PaulHigginbothamSr]

Hah Hah Ivan plays the Russian dancing music with the violin accordions and the spinning kicking music to try to keep from kicking the dancing partner with the frills. Hah good one Ivanski. So the refill tank says 100%. After the engine starts--- wha wha wha 0%

Hey did you watch Part 2 already?

[@stuzman52]

Ah, you've got a head scratcher there Ivan :) I'm ignorant of diesels as I've never worked on one, and I'm sure others may wonder too. What is the purpose of this active and passive tanks? Okay, I just looked at a video on this DEF, SCR and all these other acronyms. I had no idea these diesel engines in controlling emissions were so complicated. Here's a video link that I found interesting Ivan that your subscribers could learn more about these emission systems on diesels if they so desire. Keep up the good work! kzbin.info/www/bejne/r6u1g2t4ibumr9k

[@PineHollowAutoDiagnostics]

haha Terry, I recommend you keep your trusty Buick 3.8 running as long as possible. The sheer complexity and number of expensive components that can go wrong on this BMW truly scares me. And then you have to buy a $2,000 assembly just because they don't sell a $100 level sensor separately? No thank you!

[@stuzman52]

It's just unbelievable In prices that the European cars cost to repair. I bet your buddy was in total shock when he heard the cost of parts. Yep, I'll drive the Buick as long as I can. 👍

[@satamanschmidt3428]

Terry, hard to believe the morons that designed this crap almost won WWII. What the hell happened to German Engineering? The nation that designed the FW190 and the King Tiger now makes this shit? KEEP THE 3800 FOREVER. Wish I wouldn't have wrecked mine.

[@stuzman52]

SATAMAN Schmidt Dennis, you can't imagine how many times I've thought the same thing about the correlation of their engineering during WWII and now. I'm a WWII buff and it still amazes me the advances the German engineers came up with back then. But today, wow, just crap! Long live the 3800 😀

too bad I couldn't watch this video all the way through. easily nauseated by the unstable camera movement.

[@giveeratoot6048]

Why would you inject DEF into an engine? We could of drank that.

[@mechanic_marky]

This is actually a little painful to watch. I enjoy watching videos but these scope things are like a one trick pony. Unfortunately I have the luxury of working on SCR systems on construction equipment. Thats a $40,000.00 space race creating there. It looks like a rocket ship. But, all of our diagnostics is checking powers and grounds for proper responses to different components (injector, NOx sensors, DEF pump, heater circuit, ECM) and you find out what you have, or dont. But watching these signals on a computer I think just over complicates things.

[@PineHollowAutoDiagnostics]

I don't quite follow the "one trick pony" analogy. In this case there was nothing wrong with powers and grounds, so would you just call the DEF tank without at least verifying signal wire integrity and presence of a signal from the SCR module? Can't really do that without an oscilloscope, no matter how you spin it...
