No, definitely never been fixed, avoid like a dose of knob-rot.

Chain/s snapping, DPF clogging, EGR failing, HPFP letting go, Flexi joint fraying, swirl flaps getting sucked into the engine, the list is almost endless.
Question, You say HPFP let's go. I'm under the impression they are only in petrol cars? I'm referring to the n47 diesel which I believe has a commonrail injection system without a HPFP?

If the chain, guides etc are replaced, is it a good engine? I can't get over the price I'm able to get it for. Spending about 1-2000usd to change the chain will still make it a good buy. It's great to drive.
All DI engines need a hpfp, all diesels and most modern petrols. Diesel fuel pressure is usually around 29,000psi, which I think you'll agree is fairly high.

I wouldn't touch any N47 personally, I'd rather poke live wasps up my ass.
Thanks all for the quick and good answers.

HPFP and injection pumps are not the same thing mate. I thank you for your input and it is definitely valid. This car will cost me about 9k gbp. (I'm not from the UK, cars are a lot more expensive here). Similar cars without issues and in better condition and lower mileage are about 15-18k gbp. There's loads of little nicks and dents all round the car but I can have that fixed for about 1k at my friends shop. I do plan to replace the chain and guides as soon as possible to prevent future problems. I reckon I'll be 11-12k deep into that car fully fixed. Anybody have a link to a good timing chain kit?

Well, BMW call it a high pressure pump mate, feel free to call it whatever you like. http://www.realoem.com/bmw/enUS/showpar ... Id=13_1224


I would be after a FEBI chain kit, don't have any links though, sorry.

Is this a joke? There are plenty of high miler N47s out there - mine included. 133,000 miles on mine & it runs like a watch. If you have personal experience of your N47 going bang, by all means spread the doom & gloom (while questioning whether or not you changed the oil as often as you should). Otherwise why continue propagating stuff you read on the internet that may/may not be true? :banghead:

in september 2014 the service manager of a BMW dealership told me "off the record its only now that I would spend my own money on a car with an N47 engine" actually just before the replacement funny enough the B58

That figures. Someone who has been there, seen it & done it. A real life Uncle Albert. So here's a real life stat - of my model (320d Efficient Dynamics) BMW sold 5000 in 2010 and 7500 in 2011 before the F30 was launched in 2012. The Efficient Dynamics model continued with the F30 and they sold 8000 in 2012 before they rejigged the naming & made everything an efficient model. So at the peak there was 21000 320d Efficient Dynamics models on the road in the UK. Considering they haven't sold one with that specific model nomenclature since 2013, there is still 20800 on the road. 1% gone. You telling me 99% have had to have major work done to keep them on the road? I call bull :censored:
This is only the 320d Efficient Dynamics, all with the N47 lump. How many other N47's are out there on UK roads? 4 times as many? More? There are 515 320d's for sale on Autotrader right now build between 2009 & 2012, all with over 100,000 miles. By your logic there should be zero.
I get you've worked on a few, but the number of N47's you've worked on doesn't mean they're all like that. Negative Nellies like you bring out the worst of forums like this.

Hey Bfleming did you help design the pile of poo by any chance? :spotman:

Seriously though another point of view if I was you would be "I got lucky"

Anyway this is a great forum lets not row a ,the N47 isnt worth rowing about :cry:

Hope you get another 100000 out of yours

Hahaha too funny. I'm sure you'll all agree a lot about the way a car treats you is how you treat it. Keep oil in it. Check fluid levels, pressures and codes regularly. Neglect a car (as company cars seem to get neglected) and even I concede they won't last long.
Manufacturers are culpable though; they will design a superb product, then the accountants some in & make them shave costs where they can. Nothing should last forever, and spare parts should be sold at huge mark-ups.
Maybe I've been lucky with my cars, particularly my current fleet, but I wouldn't hesitate in having another one.

I’m with BFleming on this.

Yes, there may well be a small percentage of failures, but I bet it’s less than 1% of total production. And my N47 engined car could snap it’s chain at some point, but I don’t lose any sleep over it. If it does then yes it’s not good but that’s the same with any issues on any car/engine combo out there. E46 sub frames anyone? Some are lucky, some are not, that doesn’t mean you tar the whole engine range with the same brush.

In fact, in my large ish circle of acquaintances, parents, work colleagues, friends etc etc I probably know over 40 people with various versions of the N47 and the only issue anyone has had is a blown turbo on a 2008 320d touring, but NO chain failures. And lots of them are in the 2006 - 2011 age range with over 100k miles, so according to the doom merchants on here they should all be broken.

I’d love to see official figures for chain failures, it will be low in comparison.

I think maybe the "Doom Merchants " on here ,like me are subconsciously so angry with the way "we" were treated by BMW when it happened that it rubs off on threads like this. Even typing this is starting me off again and I thought I had let it go. Thank christ I was on the slow lane of the M42 at 9pm at night when it went a 142 mile trailer trip home with an E Europeon bloke who couldnt even say yes or no in English. Scrapped 7 years old full BMW service 105000 miles and BMW couldnt have given a toss. Doing a recall a few years later was the icing on the cake.


This must be fake news or N47 Paranoia ....or the law of buying a car and allways seeing that same car where before you never saw it :)

I am genuinely sorry to hear about your experience @Carlover. I'm not aware of a N47 recall by BMW - can you elaborate?
When putting my stats together last night I forgot about all the 1 series, 5 series and Minis with the N47 engine too, so add all those up (a few hundred thousand on UK roads alone), and I still reckon a very low number have failed. 1% of 300,000 is 3,000, which sounds like a lot. And like you all of those 3,000 are going to be well pissed off with their lot, take to the internet, write to BMW, consider legal action, go to the press etc. But rather than having a N47 with miles on it & considering myself lucky, I'd flip this this other way & say chances are 99% of N47 drivers have nothing to worry about, but 1% will be unlucky. I'd take those odds. My car has served its purpose at this stage & might be worth £3k on a trade in. I've seen nice looking equivalent cars with blown engines being sold at auction for well over £2k, so I'd lose a grand, maybe 2. Not the end of the world, my budget for my next car would just get adjusted slightly one way of the other.
