BMW’s timing chain problem comes back to haunt carmaker
The four-valve cylinder head has two overhead camshafts that operate via roller rocker arms the valves. The fuel is injected into the combustion chamber via centrally positioned solenoid valve injectors or piezo injectors. The electronic engine control was also designed for the following efficiency-increasing measures:. The engine also became available in the 5 Series BMW E60 and E61 from Septemberseveral months after the 5 series was face lifted, during which time the older M47 remained available.

This is the engine, which won the International Engine of the Year Award The N47 engine family is prone to excessive timing chain wear and premature failure. Rattling noise from the rear of the engine is indicative of the condition. Timing chain failure may call for engine replacement or a costly repair. The issue applies to all applications and power variants of the engine produced from The most seriously affected units which require the most extensive repairs were produced from The return spring on the turbo's waste-gate was not originally lubricated or covered, this frequently resulted in early failure causing the waste-gate to remain partially or fully open.
The problem was described by BMW engineers as a "known fault" and was immediately repaired BMW mobile engineers even carried boxes of an improved springhowever BMW refused to compensate customers for the excessive fuel consumption and denied this fault was their liability.

Search My Stuff What's New 3 12 24 N47 Timing Chain failure how common is it still? OK,I have been spending more time looking up potential purchases suitable for my new work commute, which is a twice weekly drive from my home nr Bournemouth to Dorking, 95 miles away, a pretty awful drive tbh, so I want something comfortable and torquey and with reasonable MPG.
My weekly mileage is current just overwith weekend trips added in Anyway, the d or d seems to fit the bill well, big for the familycomfortable and decent MPG But every google link refers to the dreaded N47 timing chain problem. I am just wondering how much of an issue this is still. BMW obviously shifted thousands of cars, the majority of which I am guessing have been fine, but it is still a worry However I believe BMW recently did a voluntary recall on the 1 series n47's from certain years, not sure on 3 series or 5 as I only heard via the 1 series fan forum.
Tryke3 1, posts 46 months. Look on the road how many ds there are, do you really think its really a big issue? My son has an 09 d M Sport and it does worry me that it could at some point be hit by this - not least because he'd come to me for financial help! These engines can - and do - take oil, owners rarely check the level, and the service intervals are stupidly long for oil that ends up looking and feeling like black water by the time it come out at 18K miles.
BMW did an "enhancement" on cars they thought were at risk, so it might be worth checking if any car your looking at a was due it and b had it. If the engine is absolutely fine now, purring like a kitten and has a great history, then chances are, by doing what we're doing it should be ok going forward. JakeT 2, posts 72 months. Stick BMW warranty on it and you'll be okay. There is a big risk best avoid cars with the bhp N47 from orcant remember.
You are far better off with a 6 cylinder diesel at this age they don't have problems with timing chains, they are much smoother than the horrible noisy 4 cylinder BMW engine and the economy is surprisingly similar ok its not quite as good on fuel but you do have much more power and a nicer noise.
Agent XXX 1, posts 58 months. IF it doesn't go bang you'll be bored to tears with it after a week. SO dull. And the 3 is definitely not a 'big' car. Certainly not a family car. There is or was a service campaign to check and replace affected parts as necessary, so it was a problem but shouldn't be one now. Someone did say a week or two back that they thought BMW might have stopped running the campaign now, which seems mad to me but meh you never know, so best call BMW and check if you're thinking of one.Hello There, Guest!

I was wondering the same, all I can find is that it was a technical update, but nothing on what was actually updated.
Sent from my Redmi 3S using Tapatalk. Read my past above. I don't know. And guessing is not a viable answer imho Sent from my Redmi 3S using Tapatalk From what I can gather from online resources, the update was an attempt to address the timing chain issues with the N Also thought that it might be the timing chain issue that was sorted. One will make you cry, one will put a smile on your face. N47 is the one plagued by timing chain stretching because of strain imposed by HPFP. They also like running bearings, there was a recall for these at some point in time.
These are pretty bulletproof and don't suffer as far as I'm aware from timing chain issues. It has a much better ECU as well - known as the kW version. Thanks Ratslaaf. That's good to know! They didn't upgrade the gearbox by any chance to handle more torque. What preventative maintenance can one do to prevent the timing chain from stretching? Is there an upgraded HPFP maybe? And the bearings?
And can the ECU be tweaked to the same spec as the better one? There was a campaign for some N47 engines, not sure if it's still valid. Not all were affected to be honest. Nope, there's a massive difference between the two ECUs. Your car runs piezo injectors and the later ones were pintle injectors, totally incompatible, so is the wiring harness.
All this being said, there's a lot of N47's on the road. Yes there were some issues but I am known to sometimes make a storm in a teacup.
ECU can't be tweaked to the newer ones spec but you can do SW on it. I will get thereOriginal Poster. Search My Stuff What's New 3 12 24 N47, fuel pump problem? Prev of 2 2 Next. Hi folks. Well I am after some help. My d N47 auto, it cut out on the dual carriage way at rush hour coming onto a bridge not a great experience I must admit!
Before it cut out, I had the car on cruise at 60mph, It felt the like car had a soft gear change, I felt something, but not a splutter.
Anyway, car wouldn't restart, and battery couldn't take much more cranking and said tranny problem, got recovered, very long story!! I had the car read:- 4CA0 oil pressure switch plausibility 4BDA fuel pre supply pressure control Rail pressure plausibility delivered controlled had them cleared and nothing, still cranks over and over.
I spoke with an Indy BMW dealer and they said fuel pump. I bought the car from a small garage, who seem to be trying to wash there hands with it, and said fuel systems aren't covered, but they might contribute, they need to talk about it.
Any ideas? Is it worth buying a new fuel pump, Can I test it anyway without software? The replay seems to work, looks clean inside of it, but it does get warm when I tried cranking the car over. Camchain seems fine, no nosies etc? Thanks Luke. OK, I think the oil pressure plausibility switch is a red herring. The problem appears to be with the fuel system.
In my experience it's unlikely the mechanical bits of the high pressure pump has failed good newsbut it does have several bits to make it work correctly. Firstly it has a low pressure electric pump located on the underside of the car I think. This is responsible for ensuring the HP pump has sufficient fuel. Does this start with you cycle the ignition. Then the HP pump is controlled by an Inlet metering Valve. Essentially this switches the fuel on and off to the HP pump depending on the feedback from the fuel rail pressure sensor.
The FRPS sits at the easy end of the fuel rail on the LH side of the engine, just under the cover, It has 3 wires to it, and the central one is the feedback voltage. On ignition on engine off, this should read 0. If it gets to 1. Will stay at 1. I have check, on cranking 4. Checked the fuel lines from under the bonnet, the black line jetted out fuel, checked all relays too.
I can't see it being a filter or even a pump now, as the car cranks over, without even a hint of coughing or spluttering to start up, just cranks and cranks, the battery is taking a hit now too, from testing things and trying.
First off, as said, the timing chain is still located at the back of the engine. The N47D20 is still being used today. I have not read anything about them changing out the engine, though there was this article from about BMW doubling down on their use of the chain at the rear of the engine, supposedly to go into production cars this yearbut I've not read where they've actually started using the engines.
These newer engines are supposed to share many of the same components, have the same amount of displacement per cylinder whether gas or dieseland use the same mounting points in the engine bay. Until they do start utilizing the new engine, BMW continues to use the N47 as a mainstay in their fleet. Since BMW will not own up to the timing chain problem publiclythe best we can do is to see what the BMW owners community has said about it.
According to the community, the problem lies with the crank shaft sprocket. This is an excerpt from this forum:. BMW recognized it as a fault and fixed the sprocket issue in roughly March some older engines were still installed at a later date but later model have since failed, the mechanics on the site have seen mainly jumped chains on manual cars that have been been ragged, auto's don't do the same harsh gear changes and so are less prone to failure.
Still, others claim the manual tranny v. Failure rate does seem to have decreased dramatically since BMW made the changes, but that does not mean you won't have mechanical chain failure on the N Bottom line, if you start hearing the timing chain start rattling, you should get it looked at.BMW до 1 млн р/ X1 дизель, двигатель N47 - сколько ходят, как обслуживать?
This is a very big job. The chains are at the rear of the engine, and requires engine, head, and sump removal to replace the chains. They engine is also set up with a set of special tools and timing plates. BMW say that any previous weaknesses are now resolved. Sign up to join this community.

Great answer. What are your thoughts on regular servicing every 10k miles preventing this problem? I've read in a few places that you should never have problems even after k miles with the timing chain if it's serviced every 10k miles for the lifetime of the car.
I'm not specifically a BMW guy, but I would highly recommend it. I think BMW's maintenance schedule is a little long for any car, but that's just my taste. Also, if you can afford it, I would highly recommend running full synthetic in the vehicle flavor of your choice.
