Don't worry about the other injector values being out - they are being adjusted to compensate for the bad one. Swapping the injectors over would have determined if it was injector or engine. Compression test would have confirmed. Big difference in money between 'working' and 'spare or repairs' M57!
So bed you are giving up, George. This content is much more Interesting than swapping steering wheel.
Understand the decision re the m57. Sometimes you have to just call it plus you've got other projects going on. Keep up the great work!
Cheers mate!
Hi done same on my e60 535 stripped injector and cleaned problem solved mine was cylinder 4 👍
Fr
Was it making pretty much the same sort of noise?
You tried unplugging the injector? Should stop it from firing and therefore will eliminate any noise
Endoscope, compression test, injectors swapping a lot of interesting videos could be done with this m57. Free content.
Most manufacturers count there cylinders from the timing gears/pulleys. So number 1 cylinder would be the back one. Great vids just got my 1st bmw E91 325d and will be carrying out all mods you’ve done to the M57 engine
That was what I thought and the timing chain is at the front on this engine
Loving the home made slide hammer. That engine noise sounded to me like a very large gap between the engine and exhaust.
My dad made the slide hammer for removing the N47 injectors 😬
great video george !nice tool you got there mate! nailed it again
Thanks 👍
Will broken swirl flaps cause the knocking sound?
Hell of a project (had you kept it) to replace a knocking rod!!!
Nice one mate for giving it a go
Cheers mate
Defo sounds like a bearing issue! Bearing shells are pooched.
Wise decision!
👍🏻
definatly a compression problem, proboply a bad injector that kept leaking on the piston and burned the piston
Good video bro enjoyed it . Keep up the good work
It would be nice to know what was wrong even if you don't fix it!
It is an older video but anyway,have same problem if you maybe did not find out what is wrong,like you said,have no time to find problem,your svirl flap is blocked one cilinder valves,I do apolovize if maybe did not write without missing some letters im from Croatia
jesi li otkrio što stvara problem?
Bet your neighbours are happy that thing sounded like a jack hammer! Still worth a look
Hahahaha I think so!
Fair dude you had a go is what it is,I got my battery fitted and programmed by a bmw specialist in rugby so that’s all good but when he plugged it in it’s saying glow plug module fault which helps regenerate the dpf, I know you covered dpf regeneration a few months back but I don’t think you did the glow plug module did you?
Actually replaced the glow plug module in this video mate. Go to 7:30 or so: th-cam.com/video/juf4LNLIliA/w-d-xo.html
@@GeorgeAusters thanks dude top man appreciate that,is it easy enough to do on the car ?your video the engine is out lol
@@simonpeters888 It’s only held in by 2 nuts and the connector but it’s underneath the intake manifold so you either have to reach under or just remove it out the way 👍🏻
@@GeorgeAusters ok top man thanks for that pal👍
Hi George. I've got a similar issue with my X6 2013 40d. The sound goes and comes. Any ideas?
I've been facing a similar issue man. Extremely hard to diagnose a fuel knock on a BMW once you've already tried the basics with no luck things can get very very deep.
Edit. After throwing the entire parts store at my car over the course of a year, I finally found out my crankshaft was warped, and cylinder 6 was underfiring constantly because of it. Hope this helps somebody.
There are ways to measure crankshaft without removing it or removing the engine, look into this if anyone is dealing with a Fuel knock, or misfire.
Do NOT always assume it's bearings.
was it the injector or something else?
@amy40c after rebuilding the whole engine, and replacing almost every single sensor on the engine, and almost every working component, I found out it was my crankshaft. It was slightly warped on cinder 6, causing it to underfire once the operating temperature fuel mapping kicks in,(once car warms up, it knocks)
Over 400 hours of trying this and that and 12k in parts later, and I finally have it fixed.
I literally, found it to be the crankshaft by ruling everything else out first. Crankshaft was the last item I replaced. Ifeel like a fckin fool lol,threw the whole parts catalog at it in any order.
But as a word of advice, whenever rebuilding an engine, check the crankshaft by measuring how far the piston is from the top, when crank is set to tdc.
Best to reference this with its set. Usually v6, v8 or straight 6 or 8 engines, usually 2 pistons fire at a time, or at least come up at the same exact time. Use a push dial indicator to check that all piston heights are same, it's an easy way to check the crankshaft without taking it out and mik'ing it on a lathe
@@tg5509 hi i have same problem on 2010 bmw 635d by turbo same noise i change injectors not change nothing i belive i something from inside😢😢
Can same one to help me to find out what is the problem with this thank you all
It's the right decision.
Agreed🙌🏼
The egr check , on my e46 320d , egr was programed out , and it jus fuckt all it had calnking ar all , then just pull out the vacum hose off and vola is all good
Sounds pretty clear that it is a rod knock. The rod has gone oval because of injection issues. You can ruin a diesel with the fuel just being dumped into the engine. Basically the injector nozzle was plugged and likely ruined both the oil and ran the one cylinder way too rich.
Yeah that's my thoughts!
George PLEASE do a quick video on battery changes, this time of year alot of us are having battery issues. BMW have quoted me £176 to check my battery, which i knows knacked needs to be changed which it does, we need good video on battery registering and coding , help us subs out georgy ( iv got a 320d lci e90)
I’ve done a couple mate th-cam.com/video/Eh41RH-tLiI/w-d-xo.html
You are godly peace be upon you oh wise one
😁
Should have put the injector onto the other cylinder to see if the fault moved.
Was screaming this at the TV 😂
Only thing is there wasn’t actually a fault code, just the fact that the injection volumes indicated too much fuel into cylinder 3. That could have been a symptom of our issue though, not necessarily the cause but I do get your point👍🏻
@@GeorgeAusters check compression in cylinder 3, more likely no compression in it.
No since each injector is programmed for each cylinder
That engine noise sounded ‘exactly’ like a work colleagues car. He took it to a local mechanic who told him he needed a new engine. A second mechanic (well known with us) swooped in and proclaimed 'he could fix it' and it was likely the injectors. He spent ‘ages’ on the car however he eventually had to give up and admit defeat. During that time the first mechanic was told it was being looked at by another mechanic. His response was "don't tell me how to do my job - it needs a new engine". Well he was proven to be right.
@Das BMW guru so your cause was the injectors? Or what fixed it?
@@pythonovitch this is encouraging me. I am in the same situation, identical sound like this (maybe even louder), I also got fuel rail pressure errors, and all mechanics are telling me that it is a rod knock, broken piston, crankshaft... Do you maybe have a video how it sounded?
Could have tried switching the injectors round and seeing if that massive over fuel on 3 moved with the injector.
The noise it's making I reckon it probably wouldn't.
Yeah I was considering doing that but honestly I need to get cracking with this car, it needs to be gone this week so left it at that👍🏻
@@GeorgeAusters Don't blame you mate. Buying refurbed injectors etc can start getting pricey too.
Injectors are coded to their position / firing order so not sure you can do that for a test.
@@Speedystig You can with ISTA or INPA
Swap the injector into another cylinder and see if the problem moves!
lmao loved that you kept in the camera almost falling over and then you just sitting on the floor of the car
Hahaha 😂
how many km/milage on this car
Surprised you didn't take the opportunity to swap the injectors, recode and check the numbers and see if it's the injector or the cylinder.
I did ohms test first 👍
1:08 nice special effects lol . 😆. Do you think that car jumped timing ?
Hahaha I wish I was that good. & no idea tbh 👍🏻
Big end????
I have exactly the same fault. Did you find a reason?
Hi did you! Find the reason?
Can someone please help me!!! I’m getting mad 😢I have knock + vibration under load from 1500 rpm to 2200 rpm I change oil every 8-10k km ,new flywheel + clutch ,new belts kit + harmonic balancer ,egr on ,fap on…bmw 330 m57 manual gearbox need help!!!!
Same for me, any solution ?
It's for the best
👊🏻
That car was useful for parts and only parts. It's an old diesel bmw with what sounds like rod knock.😀
Exactly!
Had the same problem, it's the chain
Doesn't sound like timing chain
@@GeorgeAusters how do fixing the chain cost u
Sounds like a big end bearing to me
It’s a rod bearing pal 😉
Probably 😂
Sounds bottom end. Spun shell maybe
For me it sounds like propshaft but I’m not sure
Propshaft? With the car in park?
Did you ever find out what it was? This sounds like the engine in a car i'm buying in the coming weeks. The seller is not sure what's wrong with the engine, but he knows there is a problem with an injector and that there's zero compression in cylinder nr. 2. The odd thing is that the car has had an engine replacement, and the engine which is in it now, was fabric new in 2014 and has only traveled 97 000 miles..
No I never went any further with it
@@GeorgeAusters Ok. Thanks for answering! I'll be doing some more research :)
@@remiandre100 did you find out something?
Good job bud, keep it coming loving what you do
Cheers Gary🙌🏼
Sounds like piston slap
i spun a rod bearing on a e87 sounded just like that
Did it go squeaky after revving it?
Same problem here, rod bearing went spinning on my 120D N47. It did squeak after revving.
A boroscope on the cylinders and compression test would tell a lot if the engine is salvageable or not.
For sure but I only want to spend so much time on it👍🏻
Nice video. Maybe the engine could be used for “research”
Haha I’ve been thinking of a few things😂
Do you still have injections from this engine or would you like to sell them with shipment to Germany? I have to buy 4
Message me on Instagram if you need them
shame about the engine lad.
Nice to meet you the other day, keep up with great the content :)
Cheers mate, yes good to meet you too👍🏻
5:35 I thought I was on the wrong site for a sec
😂
Diesel?
This is yes
Sounds like a rod mate
its not the engine for sure
George: "We've been experiencing some kind of storm here, just a bit of wind. Just a bit of rain....."
Climate scientists: 😭
😂😂😂
sounds to me like rod knock toasted engine
Yeah it does sound like it👍🏻
Holy crap that engine sounds like my missus doing the dishes 🤣
😂
It appears that car may have had a long hard life.
Possibly!
vacuum pump maybe ....
i think i had a knocking noise when egr didnt work as it should
Yeah I was thinking maybe the vacuum pump but like I said I just don't have the time or space for it anymore, it needs to be gone asap
wtf traktor
🙌🏼

Shit box
