Thank you George for such interesting blogs. My car is a 2012 F20 120d with the N47. I recently followed your blog on removal of the inlet manifold to replace the coolant inlet flange. I have done just on 350 000 kilometres and to my surprise the manifold did not require cleaning. Most of my driving is long distance trips between Johannesburg and my farm in the Free State, a distance of 350 km, which I do more or less once in two weeks. I am rather alarmed about your comment on the timing chain. I service my car myself at 15 000km intervals using only 5w40 pure synthetic oil. I have never had any mechanical failure. I have driven other BM's and Alfas. This is the best car I have had. Sadly, I am about to replace it.

[@lukask2489]

Brought a N47 3 series at 90K miles. Changes pretty much every single part already between 100-120k. Car runs with out any faults at this moment.

It would have been easier to place them in the front, but it´s not really a fault is just a different design,... the chain can be replaced from underneath the car, no need to take out the engine; that is what BMW service do, they don´t take out the engines.

[@Sad-Lemon]

Very informative video! Thanks! I'm driving one of these, specifically the F10 535d. What I'd like to say if you keep the service intervals at 15k miles, neglect the time needed for the engine oil to warm up and use bad quality oil then don't be surprised when everything will start to fail. My interval is 1year / 6-10k miles. I always let the oil to warm up mid-range of the gauge before I start fooling around. I've never, ever used launch control and I'm using high quality LL04 oil and high quality diesel. Don't make the mistake of using LL01 / cheap diesel or your DPF will die quickly. Especially if you don't do much of a highway daily. Happily hitting 100k miles now with no problems whatsoever.

[@a191d]

You are a legend man, I just bought 2011 F11 525d with 117000 miles. Will be checking all those parts soon. Thanks and keep it up

[@twalsh51]

Mine never failed and I changed my oil every 19k miles on my E60 520d. At 220k miles I decided to change the chain for peace of mind. Now I am on 250k miles and only the turbo was serviced and the water pump and some front suspension parts changed. Going like a clock and still reaching 140mph without any problem. But now in its old age (59 plate), I give it tlc and change the 5w30 oil every 10k. I have now decided to change the auto transmission oil and filter plate before Christmas. ☘️☘️

[@biggur5]

Timing chain on my f10 N57 broke at about 100k miles. I'd bought the car at about 80k miles and after the warranty finished I took out private warrant.. as expected the timing chain was NOT covered and cost me the best part of 2k to fix! My previous M57 was absolutely bullet proof. All I ever done was a swirl flap delete and changed the oil breather spongy thing to a vortex type. It lasted me 250k miles. Was still going strong when I sold it. This n57 has given me no end of problems and it's only just reached 120k miles.

[@CoolKD2005]

I have a 2009 E91 318D with the N47. It has now done 105000miles and the chain sound is there. The engine has performed flawless up until now. (with regular oil changes) I'm educating myself to do the chain job myself. So I must thank you for making these informative videos on this engine. It's like you say, spite it's trouble it is a great engine that really performs and still keeps fuel consummation really low. To bad that in my country(Norway) it's illegal to remove the EGR system, so I'm stuck with it.

[@dodge2451]

Check that its not a recalled item, there was a fault with the timing chains in these that caused failure (chain rubbed)... it was on watchdog in the UK: www.bbc.co.uk/programmes/articles/23p5j5wzPtYflS7kFvmKVZf/bmw-deny-engine-failures-are-due-to-manufacturing-fault#:~:text=The%20Team-,BMW%20deny%20engine%20failures%20are%20due%20to%20manufacturing%20fault,built%20between%202007%20and%202009.&text=But%20if%20the%20timing%20chain,that%20can%20happen%20without%20warning.

[@TonyJvideos]

Nice video mate, just a couple of points. Title is a bit OTT, these are common points of failure but by no means guaranteed to fail after 100k. I recently sold my 2012 e90 N47 with 199k and none of those things had failed. Just regular maintainence. The other thing is I wouldn't publicly recommend removing the EGR. BMW put it there to channel your sooty emissions back into the engine to be burnt off to comply with emissions regulations. By removing it your sooty emissions aren't recirculating into the engine but going straight out the exhaust into the air everyone breathes, so whilst it may be better for your car it's not for the environment, so yeah, that's illegal.

[@Cookieguy97]

Much appreciated I've got a 1 series with 147k. Just sorted the abs rings, now got a egr / dpf issues causing intermittent limp mode. So the egr is going, hopefully a dpf clean then that's sorted. Now I know things I should replace as soon as I can thanks. After I look in the service history, with any luck some or this has been done 😂 but I don't think so

[@barryjones872]

I have owned a lot of bmw ,s ,starting with the 1800 ,through to the present X3 ,with the n47 engine .I would recommend anyone with a BMW to listen to George and change the oil every 5000 MILES regardless.don,t do it and you will have a lot of problems apart from the timing chain,the biggest is the camshaft,rockers,valve seals ect .

[@GeorgeAusters]

Cheers Barry

[@jamesfoo8999]

"That's just down to their neglect" I agree totally. at 70k or 80k and then especially over 100K you have to expect that even long life parts will be getting tired. Whether you get another 50K or 5K is pot luck that no-one can calculate as too many variables. Either buy a new car, or one with 100K+ and expect to maintain it, or pay someone else to do it for you. Great video, gonna break out the tools and start doing some of these bits for cheap. Just wish I didn't have to take all the damn covers off every time

[@davybloggs1564]

Great video, thanks. I just used it to replace my Tensioner/pully/belt set on my E90 N47 with 170k Miles on it. I too replace oil and filter every 5k.

My brother’s 318D just got its timing chain ripped. RIP 🪦 However my 118D has done 270000 km. So far only EGR has failed(Its been deactivated) I changed the suspension and brakepads around 200000 and its been going since then. Regular service interval with good quality oil in between. Its now time to give it some love. Brake discs and belt change. Also got a whining noise. Could be alternator bearing. Best car i ever owned although it’s getting old and beat up.

[@dunnockdan]

My N47 cars over the years..... - BMW 118d/58 mileage = 250,000 miles (regular 8,000/10,000 miles) oil changes - BMW 318d 2012/12 = 140,000 miles (regular 8,000/10,000 miles) - BMW MINI 2009/59 1.4 PSA (another issue with long intervals on their chains) mileage = 150,000 miles (regular 8,000/10,000 miles). See the running theme here, oil service intervals are the secret to long life, not even expensive oil, just the cheapest correct spec I can find. Also, this will help your turbo's on the cars also, that can leave a £1k fix if these get neglected, again linked to long oil intervals.

This video really gave me hope on my recent purchase, 520d with 240.000km. I wasn’t aware of any issue at the time that I bought the car. Then I saw so many people complaining and saying to run away from that engine. I was really sad about that. However the car sounds and fells just great. Now I know what I have to look after. Many thanks for your video.

My crankshaft pulley failed yesterday at 197k km, tensioner wheel is locked, errors on dashboard: charging system failed, no power steering, no AC, engine overheating (in my case i was couple km from home and i drove it like that because i didn't know what failed,first i thought is the power steering pump that failed) 👍

[@AsiAzzy]

While EGR delete sounds good keep in mind the whole purpose of it is to lower the temperature inside the combustion chamber, and this makes the Zeldovich mechanism not to trigger as much (where nitrogen from air at high temp makes it degrade and react with oxygen and makes NOx pollutants). While at MOT on diesel afaik is only measured the opacity (and here EGR delete is actually beneficial), the NOx will be way higher! Pollutuion aside, without EGR the mean temperature inside the chamber will be a fair bit higher. This will make the engine slightly overheated. Keep a watch on coolant temperature. (wait... E60 does not have a proper coolant temp gauge. but you can activate the digital gauge from the menu before each start)

[@GeorgeAusters]

EGR delete actually means lower coolant temps. Mine stays around 87-90 celcius

[@AsiAzzy]

@@GeorgeAusters Here there are two modifications at once, since collant does not get heated by EGR gases anymore, but in theory and practice there is more heat generated in combustion chamber and this may result in lower temp overall. Could be. On my other car with renault F9Q engine after egr block the thermostat position at same temperature was higher than before egr removal. So this means the temp overall is not rising (the thermostat is taking care of that) but the heat produced is higher. (the Renault F9Q does not have egr cooler) I recently got an E61 520D with quite some milage (270000km) in pretty good shape, everything working, no errors on ISTA-D, full service history with regular maintenance done only in dealership up to 250000km at a very good price. I plan to replace the timing chain as you did in your video but would rather leave the engine in place and remove the gearbox. (i have a garage with car lift so no trouble going underneath) This way i don't mess with the wire loom on the engine. Also i have a gear puller to remove the pinion on the high pressure diesel pump so will not touch (hopefully) the mounting of the pump. I am an automotive phd engineer and teach about diesel injection principles at university. My experience wrenching is low since i don't do this every day but i've rebuilt engines and gearboxes before and will tackle the repairs myself.

[@Assimilator1]

Isn't an N57 timing chain failure really rare? Isn't it mostly the N47 that suffers this? Btw, 5k miles oil changes is over kill, 10k/1yr is fine. As for the belt, you can see when they need changing when they start cracking on the ribs, or get squeaky (I'm not referring to slipping). And I would think you'd be able to see the crank pulley rubber cracking too? Good video anyway.

[@steewee21]

no offense,but i had a bmw e36,1.6 with no problem,timing chain in 460 000km,the guy who bought the car is still using it,so well done bmw.Like volkswagen with the tfsi engines.So i bought a mazda 3 brand new in 2017,no problems yet.

[@nordicmma3193]

having removed the EGR is something like HARAKIRI!! First the EGR is used to the combustion temperature which helps to decrease Fuel consumption. Further more, the ECU needs a EGR actuator. I dont know how you feed the ECU with a EGR signal? The injection timing is also depending on the amount of EGR, especially at full load of the engine, where it uses EGR, it can cause higher in cylinder pressure, becasue the injection calibration map is based on EGR %'s.

[@rustybaws5313]

You need to have the car remapped so that it removes the error and lowers the temperatures

George, do you recommend replacing the water pump and thermostat while you're already there doing the crank pulley/harmonic balancer, drive belt, and belt tensioner? It would seem a natural time to get this done, but perhaps the cooling system is not very stressed being a diesel and the pump bearing lasts 200K miles rather than 100K. Would you choose to do it at say 120K if the pump was not weeping?

@@GeorgeAusters Yep - I'm going to supersede that - I installed it the wrong way round! And now have a proper mounting plate - the first install bounced around on the bonnet and made a racket.

Have you ever heard of dropped cylinder liners/sleeves on N47? My coolant hoses are pretty pressurize/hard and my expansion tank has a small microscopic hole thru which is leaking coolant/steaming.

Always have to laugh at these videos that have descriptions that say parts are guaranteed to fail at 100k, 150k, whatever miles. I have twp 2001 530D Tourings (manual with 173k and an auto with 170k miles) and they haven't had any of these faults. Oil change every 10k or so miles with premium oil and a premium oil filter, crankcase breather cleaned every other oil change. EGRs are clean and working, I recently opened them up when I had the covers off the front of the engine to change the water pumps on each. Belts changed when changing the water pumps for convenience sake. Had a turbo fail on the manual but this was down to the car sitting on forecourts for a year or so and the (non-BMW) dealer not doing a proper service despite what they told me. Only other non maintenance items have been air springs recently changed on both, left-hand engine mount on the auto recently changed and a split weld on the stainless steel exhaust section where it connects to the turbo had to be re-welded. An M57 properly maintained is pretty much bomb-proof it and the M50B20 I have in my 1993 520i Touring (235k miles) are two of the best and most reliable engines BMW have produced. Generally speaking the N47 is less reliable than the M57 and has problems with bearings and excessive timing chain wear two things that don't generally occur on the M57. Despite what it seems the N47 isn't a shortened down version of the M57 and you can't extrapolate issues/reliability from one to the other

Got a leaky valve cover gasket. Should I replace both the valve cover and the gasket, while I’ve got the thing off, or is it fine to reuse? If I’m not mistaken, it’s plastic, so it wouldn’t surprise me if it warped from repeated heat cycles and led to the cover leak to begin with. Got 108,000 miles.

[@Romski1978]

How you know that intake flaps it is booked, and why is that happening is because bad quality fuel???

[@Assimilator1]

What? No fuel goes through the inlet manifold on a diesel. He explained in the video why it happens, partly from soot build up due to the EGR, partly because they apparently use brass for the shaft, and partly just age/mileage. Didn't you listen to it?? ;)

Hello, I just bought a 320D but had not heard of the engine problems before, I read that a lot of the issues arrived on engines of 2009 and earlier and that some improvements were incorporated in 2011, the N47 engines were replaced in 2014, mine is december 2013, might that suggest my risk of these problems is less. Looking at some videos I saw that there was a change of timing belt tensioner, I wonder what other differences there might have been.

[@londonerr7430]

Great video like always. Quick question, if I want to keep my EGR, how often do you think I should open it up/Inspect/clean? every 20k miles?

[@GeorgeAusters]

I would say that is sufficient yes

[@shahidmehboob1401]

Mate I hit smoke coming from rear drivers side Like a oily burning smell Any ideas

[@kernowgirl53]

Ive recently bought a bmw with this engine, had egr issues. I thought this couldnt legally be removed in the uk? Keen to be told im wring lol

[@GeorgeAusters]

It’s not supposed to be removed but should pass an MOT fine

[@noelv5360]

George, very interesting video, what about the newer (2013 184 HP) engines, same problems or have some been solved?

[@GeorgeAusters]

Pretty much the exact same issues

[@doubleL_S]

Too add. Catastrophic engine damage from snapped timing chain. So , 6 weeks ago I was driving along as normal in 3rd gear doing 30. Car pops out of gear and turns itself off. I thought oh no I know what that is. Yes it was the chain but it wasn't just one chain oh no no , it was 2! Completely snapped with no prior warning! No rattles knocks nothing to indicate it was going to go. On further Inspection my ex bmw specialist told me it had cracked the cam carriers, smashed the cams, snapped the rockers! (Pics) after even further Inspection he told me that the clutch and flywheel were on there way out (no indication of this prior) the flywheel had been rattling and caused extra vibration into the engine and he said he thinks this is why it's snapped 2 chains. He has done 30 ! Yes 30!! N47 engines with chain damage or replacement and said he had never seen this before. All in all a bill of £2300!!! It's a 2011 F10 with 155k on the clock full service history every 11k maximum. Moral of the story BMW should have been sued for designing this engine so poorly! I will be returning to the trusty M57 soon enough.

[@alih1jaz1]

Any video on the rocker cover gasket? Thanks

[@grahamrowland6681]

Nice info. I disagree with it’s not a design issue for the timing chain. The service says 18000 miles then it should be good for that mileage. I changes mine at 10000 miles and it snapped. The new kit is updated so it must have a design problem

[@GeorgeAusters]

The early 2007 engines reportedly had an issue with the camshaft sprocket teeth being excessively sharp but was corrected later on. 10,000 miles is not frequent enough for these engines, needs to be every 5-6k if you want them to last👍🏻

[@Frytsz]

Are the newer N47 (2014 onwards) still prone to the same problems or lesser now, heard the timing chain is made better

[@GeorgeAusters]

Still prone to failure, but lack of oil changes and start / stop is a big factor

[@vishwa7071]

Thanks for the video. I wish i had watched the video before purchasing the X1 at 156K kms. it seems i have lot of work on my hand. i do like to work on my cars so i will do most myself. i will watch your videos as i carry out servicing. i do have a question about the intake manifold. there is lot of soot deposit around intake manifold area. it seems it must be leaking out from intake manifold. should i just replace the intake manifold? or try to clean it and see if the rod is ok?

[@fidgvey]

I reckon my camshaft sensor needs replacing. Is there just one of these on the N47 engine? And where is this?
