- My BMW E39 has an issue. Actually no one could fix it until now. In this video I am showing you what it took to solve that mysterious issue with my BMW M52 engine. It was actually a pretty simple fix :) Little hint now it isn't a 520i anymore. it is a 523i.

DUDE! Your videos give me big Mat Armstrong energy and that is high praise!
Thanks, I really appreciate that. I really love his content and he is an inspiration for me :)
I really want to see that engine running would be great the 325 engine is nice though very good engine just make sure to check the oil level regularly!
Good for you diagnosis first test second money third.
Ive had 4 e39 540i two touring and two sports saloon. If I spent money by guessing what is wrong I'd have spent a million pounds by now 😂.
Grüß Gott !
Great to see you put so much effort into getting your E39 running again.
I had a '99 manual E39 528i with leather, which I had when I moved to Austria (from UK), so that came with me.
Unfortunately, my job didn't last very long, so I came back to the UK.
I now have a manual E60 530i (M54) and a '99 E39 M5.
I still visit Austria fairly often when I can.
Grüß Gott ^^
Thanks for sharing your story.
You have great taste in cars :)
Which country do you like more to live in? The UK or Austria? Sorry, you don't need to answer, but I'm just really curious, have heard some great things about the UK.
Greetings from Austria :)

"Which country do you like more to live in? The UK or Austria?"
- Austria overall. Not by a big margin though.
It would depend on where in Austria and where in England/UK.
I really like where I live in the UK, we have many beaches, rivers and lakes here.
However, I really loved Graz, the people there and the architecture.
I also have spent a lot of time in Germany too, so like that country as well.
They're not very far away by plane, so it's not too bad being in one country and visiting the other.
I was in London the other day. Fascinating city but then, so is Vienna !
The only thing you didn't replace is the flankengerwinkle rod.
Oh you're right. I also forgot to put on some essential Zündkerzenspitzeverbrennungsfett.
Nice job! would like to see a breakdown of the old engine, but maybe you should focus on the car itself for now. Good luck with the build and waiting for more videos!
Hey there, thanks for your comment. Well, that would have been a nice idea. Sadly I' ve already sold the engine for parts...so it`s gone. Sorry. But I might know why it wouldn't have started. The new engine also didn't run on all cylinders at first (I'll show it in the next E39 video). I took the old engine harness and the connector to the 1 injector was a little bit loose. Therefore it put out a diagnostic code for the first injector. Maybe a that and the fact, that the fuel tank was dirty inside, could have been the issue that the other engine didn't start. Thanks again and have a nice day :)
haha what the hell, first one seemed to be m52TU (technical upgrade), possibly with double vanos, did you check if vanos was in good condition? they are well known for problems, as well as Disa on intake manifold.
Btw did you test engine with MAF disconnected? or disconnect it while engine is working? because i had some a-like issue in my previous e39 with m52b20 TU... If you disconnect MAF while engine is running, it should DIP in RPM for a second or so, almost like stalling, then ECU should kick in backup volumetric maps and engine should work if not better ( by ear, but definitely not by fuel consumption), then you know its indeed bad MAF... If it doesnt chance in RPM at all, it means that electric signal wires are fugged up.
Also, good test for CCV/PCV system test is to open oil cap while its running. with opened cap, it should also dip in RPM, and sound as if its dying, but not stall... then You can apply hand or some strong sheet of plastics onto the oil cap hole and check how big vacuum is there, by design it should have only slight vacuum, if its sucking in air like crazy, then you know there is issues with crank case ventilation and all that bullshit...
Anyways, interesting to watch, best of luck in your endeavors! 😂👌
Thanks for your guide😉👍
I have checked these things before swapping the engine. The MAF was definately broken. I left it unplugged, as soon as I noticed it. But it was definately not the culprit for a no start. The vanos was ok, because it didn't rattle when the engine ran. I've also swapped the Disa with another used one. To this day I still don't know what the issue was. But I believe it had something to do with the fuel supply. Because there probably was some 7 year old gas in it. I washed it out right before swapping the engine. But with the new to me engine it purrs like a kitten and starts perfectly everytime.😁
Hella Sensors are NOT oem replacements. They cause a lot of issues especially if they are responsible for the engine.
You should definitely buy a crankshaft sensor from BMW and a Camshaft Exhaust Position sensor also from BMW.
Been there, done that. Tried Delphi, Febi & hella. All of them cause issues !
Hey there, thanks for your comment.
I will do that in the future. Well, I've changed the engine, which was the better decision, at least for me :) more power ^^
nice job man
Crank-no-start problem caused by crankshaft sensor. In my 528, i changed crankshaft sensor and checked the coolant sensor for problem like this. Also the bad Mass airflow sensor can caused this. Try to unplug the mass-airflow wire and start the car. Hope this can help
Hey, thanks for your comment. Well, O ve tried a second BMW original sensor, and it changed nothing (at least for the crankshaft sensor). The mass airflow sensor was definitely broken, and I unplugged it. But the new engine runs fine and I am really glad that I swapped it :)
Ur vids keep getting better!
Thank you so much :)
I really try to make them better everytime.
Have you tried changing the water temp sensor under intake manifold? That was my starting problem
Really, never thought it would cause a no start... But I actually needed to take that temp sensor from the old engine and installed it in the new one, so that wasn't the issue. There is also a intake temp sensor in the intake. I replaced that one. But it still wouldn't start... But anyways thanks for your comment :)
Great content bro. It is just the beginning, you will get the the subscribers that you deserve.
Keep up your great work and keep those bimmers alive 🤙
Thanks bro, I appreciate your comment!😉
I really love wrenching and filming videos, so there is still a lot to come.
Hopefully this E39 is on the road soon, can't wait to drive it properly.😁
So basically you changed every part that could be suspected for a crank no-start, yet the engine refused to fire.. The main thing you did not replace is the crank position sensor brother. I pulled my engine out for nothing, but it still needed new rod bearings as it had a slightly spun no. 4 bearing. Change the crank pos sensor and that engine will likely come to life brother!
Hey there,
Thanks for your helpful comment. I've actually replaced the crank-sensor in the first episode (Tried one from HELLA and one from MEYLE). But because BMW's are a little picky I've tried it again with a known good original BMW sensor, off camera. So I might have an Idea why it didn't start. The new engine didn't run on all cylinders at first. I actually took the engine harness from the original engine and the connector to the 1 injector was a little bit loose (Maybe that's why sometimes the first injector and sometimes the second wouldn't work (loose connections)). I've also figured out that the fuel tank was quite dirty inside.
Have you experienced something similar or did you just pull your engine because of the rod bearings?
Thanks again and have a nice day :)
@@TheE46Guy In my case, on my personal 2009 318i I got it with a dealer that stated "strange knocking noise from engine" and I spent a year on figuring what was going on, did a full timing kit, hydro lifters, ig. Coils, new pan and cover seals and the last culprit to do the knock sound was the rods which was incredible at only 165.000kms. So I only pulled the engine only to replace rod bearings and then ran fine but then it wouldn't start.. so I checked every sensor with a multimeter and found out the crank position sensor gave out so I went to a junk yard to get a used oem unit because I've already invested in 4 different aftermarket crank sensors which ofc they did not run properly or at all. Such a rollercoaster my car was at the beginning of my ownership but now runs sily smooth
@@TheE46Guy Replace the crank sensor with oem used one, check coil grounds, check injector grounds, ecu grounds, it should start. Rail pressure on these port injected fellas should be around 3.5 bar, spray some starting fluid and see if it starts on that, if it does, your fuel system is faulty, after this procedure, it should be out of the equation
@@TheE46Guy Also try replacing your intake runners seals, those are found beetween the cyl head and the intake manifold as this shares a common intake for all the cylinders, and one leaky gasket ruins the vaccuum for all of em.. Also check the intake and exhaust hall sensors and replace them but only with oem ones! Check idle air control valve, and pcv valve and also brake booster vaccuum line coming from the manifold to the master cylinder brake booster, this I ain't sure if your engine has a vac pump or it straight up feeds manifold vac..
@@TheE46Guy Also check all your fuses if missing/or blown, and fuel pump and ecu relays
What about the timing ??
It was fine, otherwise, the compression would be way off. But thanks for your advice. :)
Hast du das Auto mal mit INPA ausgelesen?
Nein tatsächlich habe ich mir das INPA Kabel erst für den neuen Motor gekauft, ich muss ehrlich sagen, dass ich davor dachte, dass INPA + Kabel viel zu viel kostet ^^ Naja, später wird man immer schlauer.

Swapping the engine is a simple fix?
So frustrating to watch someone through money and time at something with no proper evidence of what they're looking for.
Obviously got rich mummy and daddy 😂
Hey Jamie! Yeah, it was also pretty frustrating for me. This video was created over the course of 4 months. Throwing most of my hard-earned money that was left at the end of the month and spending so much time trying to fix something... is hard. But at least the car runs now, and I wouldn't have done anything differently :)
