Here you can hear the difference between BMW N47 disel engine sound, when chains MUST be changed and after all three chains, tensioners and sprockets were changed.
At 00:11-00:17 you can clearly hear noise like "Shk"-"Shk"-"Shk" coming from the timing chains.
At changing process noticed, that all chains were longer than new ones, and there was an impressive free movement between all the pieces of chain. It was very risky to drive with old ones.
After change all these noises disappeared.

You have just took away all my worries. Thank you for a simple but very informative video.
Thanks from Scotland
Same here. I just brought n47, start worries about chain after all "snapping" comments, now I can sleep peacefully. Thank You very much
For those that can't make out the difference; listen out for what could be somewhat compared to (in this video's audio, at least) either a slight "shaker" musical instrument sound or a subtle auxiliary belt inconsistency noise. Thanks Headliner for posting this; seen a few videos but it's nice to have a decent before & after for reference. That's the only annoyance with diesels, they're that noisy to begin with that it's not easy to tell when something's wrong or right haha!
Sadly this motor is jus not really a silent one but the tone is slightly lower before an after
Great description.
I have an N47 with 120k miles on it. This is the best example yet of what to listen for. Thank you for posting.
Thanks for this.
Was unlucky enough to snap my timing chain not knowing this was a weakness with the car a while back and had to replace the engine.
This saves me from a lot of worrying
It was an extremely informative video. Thank you so much! I was really struggling to find differences
Almost no différences
Thank you, recently bough n47 520d , engine seemed noisy only after I bought it , but sounds completely like your “after” , they are a loud engine
Lol. Have just bought one as well... And thought absolutely same thing..
All the new diesel owners need to allow their ears to adjust to the noisier tractor🚜 sounds … saying that my ears are use to the 330d sound whereas the 3/520s are noisier.
It’s a diesel after all. My N52 E90 is a Tesla compared to this sound
Thanks for sharing this 👍
This is a really useful video. Thanks.
thanks! this video is super useful!
Funny that it sounds like worn bearing on auxiliary belt drive...thanks for sharing, exactly the video I was looking for
Konrad Knysak , exactly! But noise comes from the back of engine.
I had this noise on my e90 my2008 since had 65k km. At 185k km BMW recalled my car for fixing the timing chain issue and that noise never disappeared. Due to the low frequency compared to engine rpm I always thought it was some bearing or alternator or stuff touching something. Also it's less audible when starting the A/C.
@@headliner4936 please brother you have email or facebook or something? want to send you a video of mine and see what you think? thank you please
@@headliner4936 mine is only 56.000 miles too
@@blizzylikedrizzy8731could you please upload your video on some cloud storage and post a video private link here?
good video, thanks
I can hear that slight shaker noise if I listen for it, my car has only done 61k miles, I know there was a recall for the tensioner, I don't know if that is still active and I don't know if it's worth only getting the tensioner done or whether I should just get the whole chain kit done. either way my car is over serviced and has an oil change every 6k miles I hear people saying it's a noticable rattle, mine is like this but not as loud. it doesn't sound too worrisome yet and it's been like it for 10k miles, when I bought it I pointed it out but was told it was nothing. it's been a good car so far. might be worth just getting it done. with a new timing chain kit and up to date tensioners how long should the chain last?
Massive differance, smoother
I can clearly hear the difference. How many thousand km did the chain change? If there is no sound, do I need to change it?
Mine made no sound at all and snapped while cruising at 79 mph. Mini had it a month before to give it the once over as well.
nice video
Thanks for sharing this, mine has a similar sound, but it hasn't got worse since i bought the car. Was it the upper guide rail on yours deteriorating and causing chain stretch? I kind of want to fix mine but also can't be arsed, might just sell it and buy an older bmw with a more reliable engine.
Jay Patel , the upper chain is streching due to normal loads on these engines (material and technology of chain is too weak). As i know, these chains must be changed after 100-120k km. If you don’t change, the stretched chain starts making noise after 110k-120k km. If you hear that noise, it is better to change now, if you don’t want chain to break off and change the engine later. And there will not be any progress in that noise, usually it just break off and thats all. The mechanic was shocked, when touched the chain before taking it off, because every peace of chain was moving free in all directions and was damaged if compare with new one . I wish I could include this in my video...
@@headliner4936 yeah its annoying they wear so quickly, mines on 110k miles, which is about 176k kilometres so its definitely worn, however i do think a big factor is they way its been driven and serviced. Currently i can't even drive much anyway so I'll probably leave it for a bit. I know for some people the sound gets worse and i do check the sound carefully, hopefully it stays strong 🤞🏽
@@headliner4936 will the new chain also need to be changed again after 110-120k km ?
@@user-qz6ix7od3b I saw more N47 with original ODO and original chains at about 220000 than needed replacement, and aftermarket parts are usualy normal quality. So I would say you should listen for noises when engine is hot and starting cold. If When hot you can hear noises like in rhe video- change your chains. If you hear strange noises like not strenghten chain hitting tensioner for few seconds when starting cold - change your chains now!
I would not recommend Without any noises changing chains, because these engines can say a lot about chains with their noise when cold or hot
@@user-qz6ix7od3b but of cource if you wanna feel safe, you can change. But it is not the cheapest service
Tshh tshh tshhh sound, got it! Thank you.
Wauw thanks for the video
Hi I have a 2009 118 se 2.0 diesel auto coupe has 135000miles. My engine sounds ok but when I pull off (accelerate from stationary) when engine is cold I get a weird swishing sound for a few seconds. Once the car is warmed up it doesn't seem to do it. Is that the chain hitting the guides? Been doing it all this year. Had the car three years no issues. I do very few miles as just a weekend car. But listening to the engine reving it as you have done in the video it hasn't got that background shaker sound as far as I can make out. Many thanks
As I understand, that noise is under engine load only. I would say, that noise is not connected with chains.
On cold (especially if it is cold outside - I mean minus degrees) when you accelerate, that noise normal for N47, but if your glow plugs doesn’t work, that noise becomes louder.
If there is no additional heating in cylinder while engine is cold, diesel compression and ignition is very loud.
So I would recommend to start from checking your glow pugs and relay.
People who have commented saying "I can't hear a difference" aren't mechanically inclined. That tsk tsk tsk, or machine gun rattle is quite the tell tale sign. My missus' N47 equipped countryman is on about 106k miles and that evident back end rattle is quite prominent in the cold. The fact that it sounds like a John Deere afterwards is indeed how a diesel lump is meant to sound like.
If you want to hear a rattly camchain, just rev up any Kawasaki or Honda 600CC supersports from the late 90's or early noughties which has done about 16-20k miles and you can definitely hear the tick tick tick tick sound.
On the contrary, my OM646 C220D which has 130k miles doesn't sound as rattly as yours did on start up (or my missus' countryman for that matter). It's just a bitch of a job to do!
Thanks for pointing out the difference! Didn't know what I was looking for before
Hi mate, was wondering if I could get your opinion on the sound of my N47 ? It sounds very similar to yours in the “after changed”’ video but it doesn’t seem like there is much difference with the engines being loud anyways, but I am not the most experienced with diesel cars. Much appreciated if I could send you a video. Thanks
Send it to me. I've had quite a few diesel engines. Audi a4 and a6 V6 180hp, BMW 150hp 320d, mercedes c220 cdi and more. Just send it
@@MrTheBlastGamer Bad noise from n47 is always timing chain! Or maybe not? I would so much like your opinion in the strange noise from my wife's n47. Could be something else - but I really need advice. I posted a clip to describe the noise: ruclips.net/video/odrC04YzQ-Q/видео.html
On the same boat with you.
I'm wondering if mine problem is the same but sound is more irregular than yours, and I can hear it mostly only on idle. I can hear it louder from the back of the car rather than in front.
If this is chain noise, noise comes from the back of engine. Better you can hear behind both front wheels.
Hi mate. What's chain were most extended and worsen condition than from of this three ones you changed?
Hi! As usual the upper (camshaft) chain is streched most. And it’s the reason of noise.
very good
The engine sounds perfect now
I've had thissame infamous swishing sound for 3 years now and i've been kinda worried it's the chain. It's been getting much worse this autumn and today I finally got up to checking it by taking off the belt and the noise is completely gone, no swishing sound. The belt itself was from 2008 and so is the car so the pulleys are likely original too. Bought new tensioner, delfection pulley and the belt and gonna change them tomorrow. Hope this fixes it.
I replaced them but the sound is still there when the belt is on. Without belt no swishing, I think it's the alternator bearing
@@axuli99 what about the crank harmonic balancer? These can fail too with cracks in the rubber but hard to see.
@@406xud Very well could be, I'm not gonna replace it for now since it's kind of expensive. It could be any of the remaining pulleys. I'll be changing waterpump soon and i'll report back if that could be the one but highly doubt.
@@axuli99I changed my alternators last summer bc the battery was not getting charged. I drive a 320d from late 2010 and the swirling sound was gone after the change. My mech changed the belt, tensioner and alternator. If you changed all except that part, the bearing is almost toast. Check if your Voltage is properly loaded when you are driving.
Good
Sounds happy
Hello, the noise is that of many very small metal parts shaking in the background. Is it possible for you to show the old chain, sprokets and tensioner, just to compare the noise level to the amount of wear? Some people say that as long as you keep the engine oil clean you might interrupt the wearing process on all the components.
Sorry, but I haven't old ones on video.
Yes, apparently, frequent, short cold journeys add to the risk of this issue, and the lack of relevant early oil changes for such driving patterns.
@@marksargent2908 I would like to know if the B47 engine is different and where it differs (different chain layout? oil pump? sprokets? chain tensioner?)
some say the chain issue is solved but is it true?
@@safewaycartThe B47 doesn't have this problem
Clear difference in "rubbing" chain noise. Nice
Sounds no different after chain change ??
Ciao… ho lo stesso problema tuo del rumore forte e vibrazioni.
Tremano anche i pedali leggermente.
Prima non era così… mi è successo all’improvviso.
Forse una accelerata,oppure l’ho usata usando la riserva. Non saprei.
TU COME HAI RISOLTO IL PROBLEMA? SE PUOI AIUTARMI?? Grazie mille
Ps: la catena del mio e92 320d ha 30000 km.
Ciao alla fine come hai risolto
thats how my 330ci e46 engine sound s came on all of a sudden ,,,must be timing chain too
I have an N47T one with about 80k kms on the clock. I usually use 5w30 Castrol oil annually or every 10k kms. What mileage do such issues start to occur?
Mine started at around 120k km and lasted till 142k until it was fixed. Every three chain and guides, sprockets etc. Now it sounds just like a tractor compared to before chain fix it had that metallic periodic sound in idle when engine was warm. However, there was no chain noise when the engine was cold (< 50 deg engine temp)
i drive an 320d e91 lci 2009 with n47 and 170000km on it and still no timing chain fixed but i t runs fine so it depends on how carefully you and the other users before handled the car
@@Baoul1234 I have the same e91, chain broken on 210.000 km 🫤
I hear only John Deere
Ppl like to say they sound like tractors but as a farmers son I can tell you tractors doooo not sound like this. This is quiet compared to a tractor 😂😂
😂😂😂😂😂😂😂😂😂😂
Clearly can hear while revving
How much does it cost to get the chain replaced roughly? Looking to buy a 2011 520d with 170k on the clock but this issue is putting me off
Here in Latvia it costs 180 EUR for chains kit with all guides, sprockets and tensioner, and 300 EUR to get the job done by my experienced guy.
Or 1200 EUR at local dealer.
@@headliner4936 thanks man
The chain of a 520d is on the back of the engine, so the whole engine has to come out in order to replace it. It’s a 1500€+ job
@@Twinturbo_ it is possible without any problems to replace chains on series 1, 3, 5 without taking engine out! Even on Xdrive.
Your price mentioned is too high...
Hello how manny km did he have? I have a 320d facelift 2004, and 228000km and I think about a new chain. It makes not a such noise but everybody tells me I should change the chain in 210 000km
It had something about 230000, but chain wear depends on previous using conditions of your car (does ir have automatic or manual gear box, does it have start/stop function and how frequently it was used or swiched off, oil change interval etc).
@@headliner4936 its my baby so oil and filter change every 10000km, 6 manual, start stop does not exist in this car… so I think it isnt it a bad shape

What year is your car sir ? And what was the milage when you changed that chain ?
2009, milage was 230k, as I remember.
M47 here, sounded normal, but as soon as u gave it some gas, it startet clicking
Mine was done by bmw on a recall and still sounds the same to me tbh
now my trun i must repair chain omg !
My m47 sounds so so loud and horrible. But I’d a great engine. It’s done 140k miles with a remap for half of that zero issues and it’s so smooth on the power. Just sounds nasty
Maybe if it the mic were placed in the same location at the same location same everything the difference would be noticeable and relible
Mine has similiar sound but it disappears when engine warms up. Is it timing chain?
then it is hard to say. What milage? And when chains where replaced?
@@headliner4936 also i can hear it during engine braking just the same as accelerating. Can be heard in any revs apart from idle or very low revs. It was done about 70000 km ago

In that case there was Castrol 5w30. Bu usually I use Castrol 5w40.
@@headliner4936 5w40 best for these n47 engines. 5w30 too thin, depending on climate.
For N47 engines before 09/2008, BMW recommends 10W60 Castrol or 5W50 Mobil1. You can find that report from Munich if you do a quick search online.
I hear the same chain sound after the replace. Are you sure they really changed it?

Very subtle difference and quite hard to catch. Anyway, N47 and M47 engines sound just horrible imo. So rattling and unrefined. On the other hand, F10 3.0d is so smooth and so quiet. Almost like a petrol. Day and night difference.
I think the 3 litre diesels of any car sound a lot better than the 2 litre. The 2.1 in old Mercedes sounded like a dump truck.

The difetence is not on the loud of motor

@@Aznag1980 I absolutely deplore the way they sound! Especially since they can easily fix it.
My neighbour has an AMG C class 2.2L DIESEL!!! And Mercedes have done such a good job with that. It genuinely sounds EXACTLY like a v10 petrol amg. I didn't even know it was a diesel until she told me it was. In fact I still didn't believe her until I cross referenced her licence plate on a car parts website and sure enough it's a 2.2L diesel.
Ever since then it made me realise that good acoustic Shields around the engine and an proper exhaust system can make any diesel sound like a petrol supercar.
Which makes it all the more saddening that BMW insist on their diesels sounding like tractors.

U guys saying u do 1 oil change a year or every 10k miles that’s rubbish. U should try to change your oil every 5k. If u can do it yourself of course. I change my oil and oil filter every 5k and every 10k I change everything. It only costs £80 every 4-5 months which in my opinion is totally worth a healthy engine and peace of mind

The chain is at the back of the engine, so it’s an engine out job. Think it’s like 12 hours+ to do it. Garage I took it to said it would be about £1400 in labour costs alone. That was a rough quote, but gives you an idea of the costs involved.

Possibly Changed on Series 1? But usually it depends on driving style, manual or automatic, start/stop cycles. On automatic gearbox without start/stop system chains have better mileage range.

Took our car to local mechanic for pre mot check ( waste of time really) When we got it back it had a very different sound to engine.
