This is a really good video providing a detailed overview of the potential problems with this engine. In fact, based upon this video, I was looking at the purchase of a 2011 520d, and when examining the vehicle closely, I found a number of the issues highlighted. So, for me, I say thank you, George......
Thanx Geroge. maintenance is crucial, no doubt. BMW service schedule says 30000 km or 24months ... This is UNREASONABLE. EGR contaminates the engine hard, so I change oil & filter every 15000km. And hope to avoid timeingchain trouble. To "cut off" the EGR system should be a good intervention ... But I suspect that the ECU will "alarm", as my N47D20c is an "EU6" "Dieselgate" version (no AdBlue system).
Good informative video George, I can verify all those faults as on my 2nd engine (ext warranty) @400k miles! 1st one replaced after 201k miles and on the 2nd engine, damper wheel came off at 185k miles last year. The engine was rebuilt but failed this May nearing its 200k miles - in garage at the moment with loss of compression on cylinder 4 and swirl flap fault, being assessed in what is covered under warranty or not.....
I just bought e82 118d...awesome car ...just want to say thank you for your videos about n47 engine and I will remove egr and dpf becouse you sugested it...thank you one more time...peace
I have the N47[C] on an X1. 115,000 miles. Mpg suddenly dropped from 37 to 29. Flex pipe was cracked, but with new flex pipe, problem still there. I just do mainly shortish journeys these days so just sprayed Wynn's EGR cleaner (£8) into the manifold while parked in Halford's car park. Too early to say if it helped but this video gives me great insights. Thank You Very Much.
Best Chuansatien No symptoms for me. Failed while driving. All belt driven ancillaries failed (I felt instantly the power steering. Overheating as the water pump isn’t running a couple of minutes later). Failed for me around the 125k kms.
Regarding that little hose. Mine cracked (was plastic) meaning I spotted smoke coming out the engine bay! RAC taped it back together to get me home. Replaced for £16 odd quid.
Hi George, I have a 2013 520D with the N47 at 95k miles. I have had a couple of issues recently diagnosed as a boost leak that a new reinforced intake manifold sorted but I am currently on the may back from a very long European drive 1000+ miles and have a new issue that keeps happening. I have recently also spent quite a bit of time effort and money trying to diagnose a shudder at 70-80mph with mechanics suggesting control arms, buckled wheels and tyres as the likely culprit. All wrong. Now I think this shake/shudder is a symptom of what else is going on…… This warning hasn’t come on previously, I use the car locally normally, not going for longer than 30 minutes at a time. Now with the car full with the family, fuel and suitcases I still get the shudder but is much worse going up long steady steep inclines AND DECLINES! but is joined with a Drivetrain warning telling me to drive moderately, full performance is not available and to seek BMW service support. I have read it’s possibly glow plugs, injectors or High pressure fuel pump that could be the issue. Any advice very welcome….
Thanks a lot, my BMW is nos 290000 km ans most of the problems you describe happened but you forgot one, there is also a problem with the piece between the oil filter and the engine when we have major leak oil and coolant fluid is probably mix with
@@GeorgeAusters I have a question... If a car I'm buying had 180.000 miles in clock, should I be worried about the timing chain issues or if there was a problem it should have shown already? I've read timing chain issues on the N47s come out between 40 and 100k miles on clock.

Hi George, I have a 2009 118D with the N47 at 120,000 miles. The car has developed only what I can describe as a 'surge' at around 1,500 rpm; the car tends to jerk under constant throttle, so to speak. This is intermittent, but I have noticed that it doesn't do it when the blowers/heaters are OFF. Scoured the web, and it seems to be a common problem that nobody has got to the bottom of. Recently has EGR valve replacement, along with glow plugs and a glow plug module. Have you come across this surging issue before? Great channel. I have carried out lots of repairs based on your videos. Best wishes, Graham
Hi George, I've cleaned my MAF sensor, had a new EGR valve fitted but I'm still having EGR and MAF related issues, with EML illuminated. It feels down on power, almost as if the turbo is not being used. Spent a fortune to get this far, any suggestions?
Hi I have a problem with 2.0d N47. After the car accident, the car cannot be started on Startspray either. (Flashlight fuse repaired). It's a KO feeder but I spray it into the suction and it doesn't even fire it just spins spins spins ... Thanks for the advice
Hi, I've got issue with my N47 engine and I was wondering if you'd have an idea on this. When driving at about 70km/h the car suddenly jerked as it has lost some power and started shaking as it was running at 3 cylinders only. The performance went down very much, and the shaking is worst when idling. The car is also very loud , it almost sounds like a tank and inside I can smell burning plastic. There's no warning light on the dashboard and diagnostic has pointed out some problem with swirl flaps. Do you think it's possible my engine is destroyed by broken swirl flap? Or could this be a faulty injector ? Any help appreciated , keep up the videos !
Hi, maybe someone has idea why my injectors clamps (holders) snaps (cracks). Got changed all 4 about month ago and again one of them snapped. What can cost this problem? Screwing bolt too hard ??? Or if it been chipped (I'm not sure, last owner said it has chip) so injectors makes too much pressure and cost this problem??? Have no idea, would like to hear your thoughts. My car BMW 318d E91 2011 N47
👉👉👉Help please: i own 2008 bmw x3 e83 2.0D 4x4 automatic with 145000 km (110000 miles) on the counter.A couple months back i had issues with rough idle. When i would start the engine for the first 20-40 seconds rev's would go up and down with a bit of a white smoke from the exhaust. I cleaned the injectors/new kit, new glow plugs with new module....car is fully serviced, so no issues there. Still when starting the engine i have rough idle for 10-15 seconds (no smoke) and as well while driving form low speed and when it comes to around 1000-1100 rpm's looses power/hiccup...and when i pass those revs all is fine. I checked maf sensor, i have put new one for the test, same happened... Is it maybe the fuel pump or something else...PLEASE advice!!! The previous owner: changed egr, dpf, cleaned turbo. I did a good service... Best Jure
My car (2007 e90 320d 163hp) is on 167k never had the timing chain replaced, the egr is still on, I’m planning to do an egr delete but I’m worried that it may cause problems in the long run, i service the car every 8k-10k with Castrol edge oil, how ever as of lately I’ve noticed a lack of power and throttle response, any tips of what i can do to resolve this would be much appreciated
I've got a mini cooper Sd with an n47 2.0 engine, it all appears to be running fine with no active or pending error codes. Yet when I look at the MAF readings at idle they fluctuate between 0g/s and about 16g/s. This happens through out the rev range whilst driving, the only time it stays stable is when a regen is happening. Have you seen this before?
I smell all the time exhousf gas in the cabin when the car is idle when i drive no smell at all. If i remove egr valve does it get any better ? My car is F10 2012 5.20d
Which is the best petrol engine on 5 series after 2016? I do a lot of short rides as my city is small so I am not shure is diesel good option... I do 10k km per year.
Thanks for this. I have a fault which someone else may know about. On my F30 N47 car, I smell slight smell of oil/fumes in the cabin coming through the vents if I switch the fan completely off. Not all the time but most of the time. Initially I thought it might be leaking gasket or oil leak around filter or previous oil spillage onto exhaust manifold - but cannot spot any of these. Any advice appreciated.
I'd say your air intake manifold is leaking at the front. Lift off the engine cover. Check to see if there're traces of black on the sponge underneath. If so G is doing a video soon on repairing it. Manifold is 800quid from bmw.
@@aerosert1992 sorry still have the issue, just living with it by making sure blower is always on more than 3 bars. 2 mechanics couldn’t find an issue, no leaks around engine. I Plan to get a boroscope camera down through all the air vents in the summer, I think it’s going to be DIY diagnose/fix it yourself issue! Please do let me know if you resolve yours.
@@aerosert1992 if it helps, one other thing I have noticed about this issue is that it’s worse when the fan mode is blowing at the windscreen. If you change the mode to straight ahead (to your face) it’s much reduced. Good luck.
Common problems timming chain guides made of plastic and hydraulic tensioner teeth where very badand don't hold tensioner no more even with good oil pressure it's just fails and guides break up and do damage to rocker cover break cracks cover and chain flops about making all sorts of noise ,, 1500 fitted any BMW
Apparently removing the EGR can make the DPF clog faster as all the exhaust gases will be going through the exhaust not through the intake. However logically this doesn’t make sense because the DPF will regenerate and clear the soot as long as the engine gets up to temp regardless of whether the EGR is in place or not👍🏻 Easy solution is to remove them both😊
The chain's go from 25k (mainly down to the silly service intervals) had mine since 16k has 120k on now, when I 1st got it I did high miles, now lucky if I do 5k a year, but gets serviced every year, when I did more miles, it got serviced twice a year. Also personally don't think its a good idea to remove the egr cooler, as its part of the cooling system, that needs to go round the system, but I might be wrong...?
Epic video man. Is this vid solely meant for the diesel engines, or also petrol? I'm looking at N47 engines on the 116i and 118i. I hear that usually the chain fails on diesels, and that petrols are not subject to this problem. What's your take on the petrol engines?
where did you buy your EGR block plates / EGR delete kit from? and who tuned your car to then remove the EGR system from the software to have your car running normal? thanks
Hi I have an urgent question. I want to remove egr system but one said to me if u do that u need to do a dpf delete aswell bc it will be under more pressure without egr but I dont want black smoke coming out my car . And my intake manifold is starting look like its melting from hot gases idk whats the problem every mechanic has different fixes.
How reliable is the chain on the m47 engine? Is there any symptoms of a chain going? With the injectors if they arnt seated correct can they be noisy. Great vids keep them coming 👍
If you hear rattling when you're sat in the car, go directly to your garage. My chain failed and the engine rebuild cost me circa £2000. Had I had the work done before hand it would have cost half as much. The car has been great ever since.
Hey man! Just a quick question. Does EGR delete contribute to MOT failure due to high emissions etc? Have you ever had a problem with emissions on MOT after egr delete...thanks in advance
Hello George, I own a 320d Touring X Drive from 2013. The car was been serviced quite regurarly, 14000 Kms give or take for oil changes. The car has 117000kms. Would you change the timing chain if you were in my place? Do the latest N47s have any difference so are less prone to failure. Sorry for the long post. Nicolas
Hi George. I have a Aug 2009 build E88 and the info by the drivers door that states tyre pressure, colour code etc states my car has N47D20C ? is this definitly a 184BHP and where will it be located on the engine block for me to cross ref? thanks
@@GeorgeAusters thanks for replying I just got the car like 1 month ago didn't know much about BMWs as this is my first it has 150k miles on the clock is it more likely the chain was changed but don't know for sure as there's little history about the car.
Do you the reason to why my father inlaw just had his replaced and its melted again same place apparently iv not looked at it as of yet he lives a couple hours away from me.
Hi George I have a 120d auto with the n47 engine and I get a vibration when I put it in reverse with the break pedal pressed but not in drive any recommendation would be appreciated thanks Martin
Very good videos George. I brought a 2010 318d msport with 75k on the clock about a month ago. Now been told the timing chain needs changing. Don't suppose you fancy doing mine as well do you 😂. Just joking. Would you recommend doing the clutch and flywheel at the same time?
Hello. As you clearly know what your doing, I believe my crankshaft position sensor has failed. Do I need to remove my intake and starter motor. Or is possible to get from underneath please? BMW 320D on a 2006
Had a stage 1 done to my 2009 E60 and after a few weeks I've noticed diesel fumes coming into the car especially when starting and idling. Replaced the crank case breather pipe you mentioned as garage said it was broken. I'm sure I checked it earlier and it wasn't 🤔. Still have fumes coming in. Garage said it's not a crack in the manifold either. Any ideas? Cheers in advance.
Diesel fumes means the exhaust has cracked somewhere or there is a fuel leak. Could possibly be on the EGR system. The pipe that bolts onto the exhaust manifold is prone to cracking. Also check on top of your rocker cover for pools of diesel if the leak off pipes are dripping. Keep me updated how you get on mate👍🏻
@@GeorgeAusters oil change was just done. Dpf should be fine, no light for it on. Computer said it was fine and regenerating a few weeks ago. I will try to get the turbo out tomorrow and have a look what is the problem. But I can just say that atleast my n47d is a piece of shit car and engine
My 320d doesn't seem to have had a timing chain replacement, but I'll be getting something replaced soon, so would the mechanic be able to tell whether there's an upcoming problem with the timing chain or is it random? It's at 133,000 miles already, so would a timing chain replacement be recommended, or is it not needed unless any physical damage is visible/noticeable?
@@GeorgeAusters Thanks. I'll see whether I can confirm when/if it was last replaced because the car so far (from 2011) has been looked after quite well.
@@skrivelis4315 I haven't changed it (yet?) as I've just been taking the risk of assuming that it's fine. There have been no signs at all of problems, either. I believe that it's at around 145,000 miles / 233,000 km now.
Hi George, have you ever had problems with the turbo actuator? Mine keeps going into limp mode at certain revs, can hear the turbo flutter on acceleration then reduced power comes up on dash but no EML or code! (I have scanned with INPA & ISTA D) and will boost normally upto 3k and then its like the ecu cuts all power and becomes "gutless" I'm also low on boost but turbo is good and has acceptable movement on the turbine. When I bought the car it had no boost at all (actuator linkage was loose, tightened and was perfect afterwards) but have checked that again and it's fine. Any ideas how to check correct operation of the actuator seeing as it's electronic? When I unlock the car or open the bonnet you can hear the actuator "ticking" like it's trying to "initialise" it. Car does boost, although like I say not as well as it used to. 2007 520d LCI N47 with 230k miles with chain replaced around 1k ago, flywheel and clutch replaced, swirl flaps removed and blanked.
@@GeorgeAusters yes that's correct, they were removed due to parts from it being ingested and took out a couple of valves (so don't believe that the swirl flap problem was resolved on these engines) which resulted in the almost complete rebuild of the engine. What about the Turbo Actuator? Apparently that is also now quite a common failiure item, just wondering if you have any advice on testing that?
Hi, Any idea where i can get a intercooler hose from for this engine? I have the same engine and the turbo air intake pipe has a leak where the connector is. Any idea on where to purchase or price would be great thanks.
Out of interest, at what point do these become common? I’m looking at a 2013 320d with 40K miles... are they’re any of these problems I should concerned about?
hi e90 320d n47 in city consumptionis 14 lt/100 km after change fuel and air filter and engine oil. Before it was 12 lt/100km . always i think it is too much for this car but i didnt find any solition .. what is your opinion? Thnx
I have an 120d N47 and when the engine is warm it starts harder than when the engine is cold... when cold, it starts so easy and when hot... difficult. Any ideas?
Hi, great video. Anyone else had problem with the engine cover my one is vibrating a lot. if i put my hand on it the noise disappear. it may be the 4 pieces of rubber ? or someating else?
@@FortuneMax1Sorted out in the meantime ,in my case the problem was underneath. I replace the Vibration damper (CORTECO -180£ from Eurocar parts the original is about 500£ ). Then the 2 diesel pipes coming from the fuel tank was touching the car body some times at the point where they curve to go up to the engine. That has sorted out any kind of vibration for me. If the problem is the vibration dumper when car is gear with engine on the handle moves a lots right an left.
I can’t say whether that is possible or not, but regardless the EGR needs to be mapped out and removed from the software. It’s much better to remove the entire unit though if you don’t want to use it.
My car is on 136000 I bought blanking plates I’m going to be removing egr as per your video, do you think my intake manifold is gonna be rather clogged and if so can it be cleaned without removing it like Wynn’s or some other spray or chemicals
@@GeorgeAusters Checked the injectors today and the rubber plug you mention with a piece of tissue on a stick (!) But couldn't find anything. Maybe I'm being too 'fussy'. The smell is very faint. I'll take another look tomorrow!
@@GeorgeAusters don't glow plugs last the life time of the engine also is a bmw with full service history a good way to hope your egr and dpf are in better condition than a car without the history ie do they service these items somehow at intervals? Thanks... great video btw mate
I would love to have the tune for the egr removal. Where can i get this done? and is there someone that can do this remotely? also want to remove the dpf so i can have a little more noisy exhaust. Any info is great, thanks. I have a 2015 n47 with 78,000 all recalls done and absolutely no timing chain noise.

Hello champ! I have just sent you an email with common problems that I have I would love if you could share with me your feedback what I could do:) Many thanks in advance!
Hi George. Awesome vid once again. I have e60 520d lci. Want to know where is my dpf? I have a small box on the downpipe and a rectangular box further down. I've gutted the rectangular box assuming that was the cat as it was blocked. Wanting to remap the car but was gonna get the small box on the downpipe gutted but its gonna need welding. Which is the dpf? and any advice appreciated.
@@GeorgeAusters cheers. Much appreciated. So can I get the car mapped and dpf and egr delete now without touching the cat? Or would you recommend removing the cat aswell.
