This is a Bosch CP4 High Pressure Fuel Pump in a Diesel BMW X535D.
It is similar to the Bosch CP4 pumps in LML Duramax and 6.7 Cummins and 6.7 Powerstroke Engines.
Big thanks to @AreaDieselService ! Be sure to give them a call for any Bosch replacements. Like Scrappy Industries, Area Diesel Helps us with our 1968 bulldozer one week and a 2018 BMW the next!!

Is there a part number for that special tool for the back bolt? Where can I get one. And is it pretty much impossible for a shade tree mechaic to do this without the tool? Very thorough and enjoyable video, thanks!
Yes the tool was 83302448914B I see it available online. Yes you definitely need it. I think there are different ones though depending on the year
@@ScrappyIndustries Is the dummy plug in back plastic and how tight do I want to install the new tool. Danger of stripping? And how tight fuel line fittings? This is a wonderful video! Thank you!
Even though I will most likely never have to complete this job, your video was still excellent. I’m glad you decided to put more time into TH-cam, because your videos are amazing, and your channel has became one of my favorites.
As a retired BMW tech they would have heard me in Munich screaming ...kudos to you for your patience and your thorough explanation ❤❤
I enjoy watching someone work on their vehicles and maintain a clean and organized shop. Great job!
I don’t miss working on cars anymore. They got a lot more involved. Give me a crane ,forklift ,dozer anytime. Nice job brother you have the patience of a Saint.
You know if it was easy, everyone would be doing it! You have a ton of information to give to everyone who would want to attempt this repair.
Met a woman in her mid-60's this last summer who had never filled a gas can with fuel, never ran out of gas or had to mow grass. The struggle is real
Sounds like my wife.
Friend, I worked with a Singles Again ministry in my church. It would break your heart to know some of the stories I heard from newly divorced and widowed women. Some did not even know how to write a check. Some had no idea how to put gas in their car. And on and on. I worked a maintenance manager for a trucking company and got one of my mechanics to volunteer a Saturday. We had all the men and women who were interested to bring their cars to the church parking lot and he and I went over every single one of them looking for bad rad hoses, fan belts, etc, etc and instructed them when and where to take them for regular service. And yes, there were some men just as ignorant.
Your video style is so informative. I learn about all sorts of things that I had no intention of learning when I began watching the video.
You are doing amazing on your videos!! Area Diesel rocks!! Thanks for sharing
Sam, the design engineers, no matter the make of a vehicle have no clue how difficult some things are to service and people wonder why the cost of repairing vehicles is so expensive. Sam a good video, and want to Wish you and your Family,a very Merry Christmas 😊
Almost like working on a jet engine while it's installed in the plane.
That is ignorance or a lie... Engineers do know. What YOU don't know or refuse to acknowledge are ALL the other constraints we are balancing.
Send it to Area Diesel to have them check it out or as a core exchange and get back to you on what they find. 😊
The 3.0 Duramax in my Sierra is common rail. Common rail is supposed to be much better, provide more horsepower and much more efficient. Nice video Sam. Cheaper than having the dealer do it. And you know it's done right.
You are a brave and talented man trying to fix a BMW!
I think the pump is fine, no need to spend $1100. Until you need too. But I thoroughly enjoyed your video.
If I was a cynical person, I'd say it's almost like modern manufacturers don't want home mechanics/independent garages working on their equipment
Equipment that their own franchisee's can't cope with if it's not 10 years old or younger
I wonder how much of this stuff will be around in 30 years time?
Very very nice job, Sam.
And a very happy Christmas and peaceful New Year to you and your family
That's exactly the case
Glad to see you got it all back together and done buddy! Come on down to the dealer, we can make you the official diesel tech!
There's our man from Scrappy Industries... Working on SCRAP once again!
Great video my mate thanks for sharing it wishing you and your family and friends all the best for Christmas and the future ahead
I’m glad you decided to put more time into TH-cam, because your videos are awesome, and your channel is one of my favourites.
As an owner of the previous generation of this car, I'm really grateful for my front mounted CP3 right now. 😅
F15 has the 8 speed and nicer interior and easier steering than the E70, but they have a lot of other drawbacks unfortunately.
Enjoyed the video! I hate what the car industry has done with all this new crap!! Your a better man then me..
Love you guys! Wish I knew enough about mechanics to do what you and Matt do. Enjoy every moment
MM77 Approved 👍🏼👍🏼
It's astounding the amount of components the jam into an engine bay, battling for space with the wizardry found behind the dashboard.
Merry Christmas to you and your family.
Great job 👍🏻
Nicely done!
Awesome!
I wish Merry Christmas and a Happy New Year to you and your family. Greetings from Germany.
Great stuff real world
You are a good man to help! Merry Christmas.
Good stuff Sam
Good job
Good job Sam! Merry Christmas to you and your Family!
Made for good viewing bro. Safe travels to you and family over the festive season. Ken. 🎄
NICE LOOKING SET OF FENDER GUARDS
Thank you ..... excellent video !
It looks like you've got some expert helpers there Sam.
I understand your reasoning for changing it so I will leave it at that great video thanks for sharing have a great Christmas
Merry Christmas @Scrappy Industries from a fan in NewZealand.
You’re the man Sam! Merry Christmas
I’m not a long video fan, but I enjoy your channel.
Thanks for watching!
Hey! Good morning Sam! Merry Christmas to you and your family!! 🎄✨
Fantastic Job yuo are a good mecanic 👍😀
Merry Christmas Sam
Merry Christmas everyone love watching your videos keep up the good work ❤❤❤
G'day Sam, greetings from down under.
Merry Christmas to you and yours and a safe and wonderful 2024.🤶🎅🏾
That is BMW for you Sam.
Marry Christmas everyone 🤶 🤶 🎄 🎄
Good video. What a pain in the rear. That is a Better Made Wreck for you. Take something simple and make it impossible. The struggle is real. First one I worked on was a 2 hour job to replace a headlight. Absolutely horrible. Best advice, Unscrew the radiator cap. Back the car out. Pull a new car in and replace the radiator cap. Lol. Merry Christmas to You and Your Family. Cheers.
RAM recalled 340K 2019-2020 Cummins trucks to replace the CP4.2 with a revised CP3.3. The CP4 pump piston cups will rotate in the bore and scrub the roller & cam creating a giant glitterbomb. They are not to be trusted running higher RPM's/pressures. Because they don't isolate the lubrication fuel from the engine/injector fuel supply, the whole fuel system is trashed when they let go.
Those jobs where you have to "look" with your fingers and not the eyes are most fun don't you think.😉 Great video as always Sam. Merry Christmas and a happy new year .
Merry Christmas happy new year to you and your family pat the shop hippos on the head !
Notorious for check engine lights too! Some BMWs you will never get check engine light to stay off!
I'm no expert on fuel pumps. If it were my vehicle I'd send it to area diesel service and have them go through it. They say it checks out put it on the spare parts shelf. The fuel pump on my wifes diesel Jeep liberty failed while she was driving it. Replaced it ourselves. The bosch pump was 1200 rebuilt. I forget what a brand new one cost. Great video keep them coming.
As a aircraft mechanic you see what we deal with sometimes, you also tired out the pups they needed a nap watching you work lol
Towed in a customer with a locked up engine, i had the tech put it on the rack. Checked oil, not a drop!
Asked customer who changed the oil last? Customer "oil change? What are you taking about?" Long story short, customer was never told to change the oil,customer had know knowledge of the proper maintenance of a vehicle. Customer never had the oil changed in 21k miles and locked it up!.
2015 jeep grand Cherokee. 6cyl.3.2
Way to hang in there! 🤓
I replaced the CP3 on my LBZ Duramax. The amount of STUFF You have to take off to get to it is mind boggling! It mounts to the back side of the timing cover down in the valley between the heads, but you have to take the front timing cover off to pull the gear off so you can get it out. I’m not a professional mechanic but my father was and I spent my entire life with a wrench in my hand (or in my mouth when I was cutting teeth) and it took me 13 hours to change it.
I loved my BMW's, but they were a pain to work on. But the way they drive so makes it worth it. Had to sell my 535i when I moved up to Montana. Too much snow & not enough ground clearance, so I bought a 4x4 truck.
Damn, Sam. Going in deep there. Nice work. Leave it to BMW’s engineers to require that special tool. Interesting design though.
Hey Sam. Merry Christmas from Texas.
Great job on the pump.
I just want to say, you don't have to keep working blind like that.
Get a depstech endoscope. You and Matt @dieselcreek both need one. Get yourselves a cheap android tablet with Wi-Fi and make it a kit and BOOM you can get an eye on all those hidden spots hands free. I love mine and I only have the cheapest one they have. You could have actually looked down inside that cover on the back of the engine if you wanted to. You can look in bore holes down the intake inside injector holes, inside an engine bore and they are waterproof to. And apparently they are non sparking because mine has been in a gas can with no effect.

Now you know would you taken a chance on the pump if it was run a little longer with the gas great watch Merry Christmas to you and yours 🎄👍👋🇨🇦
God love BMW - my belly pans are littered with sockets, spanners, and bolts!
👍👍👍👍👍
Nice job, these techs nowadays must have to be contortionist or at the very least double jointed to get into some of the places they do. Interesting vid to watch, learned a couple of things from it sir, thanks.
Man!, what a nightmare. Make sure you write all of the missing information that you need to do this replacement on the instructions for next time. Hopefully there won’t be a next time. Merry Christmas to you and your family Sam. Take care and stay safe.
👍🏻🍻
I suggest seeing if Area Diesel Service will buy it from you and sell it as a refurbished pump. They could always go through it just to make sure there's nothing wrong with it, but I'm pretty sure that if they watch your video they will know if they need to touch it or not.
Make sure that you replace the braided engine ground cables (6?) Of them.these will fail and leave you stranded. I use regular battery cable
Sam I'm sorry but I find it funny that your wife or your mom drives a BMW it just seems wierd in a country/farming lifestyle.
That being said you prove to have no fear in working on high end vehicles or anything else for that matter.
Very impressive.
Farming can be incredibly lucrative.
I drive a grain truck for a farmer so I"m well aware@@nmccw3245
The lubricating properties of modern diesel fuel isn't much different than gasoline. In the old days, diesel fuel spilled around a fill cap would leave a film that would collect dust but now it's more like a cleaning solvent that doesn't leave a trace.
The GDI HPFP is totally different that that CP4. The GDI run between 2200 and 3600 psi depending on application.
I didn't think it really ran after the fuel contamination. I never would have replaced the pump.
Nice job very interesting. how was the pizza
I can feel your pain just watching through TH-cam!, I was just confused how that pump is mounted in but you had to screw in that special tool?
I am surprised there were not codes you had to use to make the computer happy
Congrats to you. And yes, there is a difference in diesel or gasoline pump pressure. Diesel needs the pressure so it can atomise (form a mist). Gasoline just needs higher pressure than the combustion pressure. Can anyone tell me at what point gasoline is injected?
So your engines are before 1870/1900? At that time doxford began building reversible marine engines. Part of this was that a common fuel rail was used. Because of timing the injection.
2015 Ford Focus with a DI 2.2 ramps up close to 3000 psi
Yes you can use a bunch of universals and extensions to reach a fastener, but at what point does it affect the accuracy of the torque wrench or does it? Good video.
Any time the universal is off axis. 😂
When bmw skips those step dose the customers get the break on booked time also
Doesnt matter he sports a John Deere hat, nuf said lol.
You need a VR headset connected to a flexible camera.
"Inconvenience " is BMW's middle name. I'm surprised the instructions didn't start with:
1) Pull the transmission
2) Drop the K-member with engine and front suspension
3) Install new pump
4) Reinstall in reverse order
Many times, factory directions will go into detail on things that are obvious and leave out the details on things that are not obvious. If they do provide bolt sizes, it will often be thread sizes not bolt head sizes and types.
Although its probably fine, I'd be worried about if gas washed out the cylinders when it wasn't able to ignite and scored them. But I could be totally wrong, and she runs so I'm probably wrong lol.
Lol possible but I think it’s perfectly fine
Surprised there arent reverse threads involved somewhere.....Those German engineers love to make things complicated....
Does this have anything to do with one of your old videos when there was gas put in the car? I remember you having to drain it.
Yup. This is a preemptive injector pump swap for peace of mind.
So Area Diesel didn't offer a core return?
Hey, wait a minute ... I saw you take 3 parts off a BMW engine without unplugging a sensor trace ... how'd you do that?? 🤣🤣
Dont you have to lock the engine before change the pump ?
I didn’t because it is keyed so it really doesn’t matter where when engine is when you change it
The things we do to keep wives happy.
Below 10 European use uneven numbers... My experience.
If I'm not mistaken, that cp4 fuel pump is not as reliable as some claim it to be
its not, the cp4 has been shown to be a giant piece of crap on anything it has been installed on. If I was forced to run one, id be adding a lubricity additive to the fuel to try to keep the pump from eating itself.
Wonder what German engineer thought it’s a brilliant idea and put the timing gears at the rear of the motor.
He was angry at the world. I guess you could call him a sour kraut.
Also, CAT has some rear gear train engines as well.
It was marketing. Do you know how much extra they can charge for a timing set change.
All of them.
He knew he would never have to work on it.
the gas you put in will eventually break down and rot all the neoprene seals in the top end of fuel system.
Ask me how i know this!!
You are really beaming now…..
If your torque wrench was just too big, but you had enough clearance for a long handled socket wrench, you could have made your regular socket wrench into a torque wrench. Measure back a set distance from the socket center to the end of the handle, and then use something like a fish scale or strain gauge to apply the right amount of force at that point. Some math is going to be needed, so it might make it a little more difficult for some people.
That was a waste of money repair Sam. There was nothing wrong with it. But, still enjoyed it though.
typical modern automotive design "we could mount this part on the front of the engine, where it's easy to service, or we could mount it on the back of the engine, where it's a colossal pain, and requires special tools, and will likely draw blood"... yup, it's on the back of the engine, because it creates a "cleaner looking engine bay", or some marketing wank like that...
You want to replace the presure pump for no reasonable reason. I can see this part is not faulty.
Well these pumps are pretty well known to let go around 100k so if nothing else we were past the halfway mark. More of a feel good thing
You Know Sam the guys that design these pieces of junk never have to work on them that's why they are difficult to work on. Dave D.
