Had an E92 full Mpack automatic 320d for 2 years. Bought from first owner who did an amazing job on maintenance. Did maintenance interval myself every 10k km's. Filters and quality oil. Did a remapping giving it approx 200bhp. Drove the absolute sh*'t out of it day after day. But!! Easy driving when engine was cold, gave it time to warm up and after hooning always let it run for a while before turning off. Because of the weight of the car I was not so much impressed by the performance, but it was an amazing quality built car with lots of 'souplesse' and also I liked the automatic gearbox! Never had any issues what so ever! Maintenance is key!!! Edit: forgot to mention, bought the car from first owner at 120.000km. Sold it at 180.000km so drove 30.000km per year...

very informative George! ive brought a 320d n47 with 80.000 miles not long ago and I have changed mostly everything you've mentioned in here. The only common issue with these engines worth mentioning is the oil filter case and oil cooler gaskets ,

Love yours videos always quality made and explained Thx you 🤝👍🏻💪🏻

Finally some good words for N47, keep going mate!

Keep up the great work 👍 👏

The tensioner guide is held against the chain by the piston of the chain tensioner. The oil in the chain tensioner provides directional damping by virtue of a non-return valve. In conjunction with hydraulic chain tensioners and tensioning rails with plastic anti-friction covering, the chain drive remains maintenance-free throughout the entire service life of the engine.

I have 2014 f30 335d for last 4 years without any issues whatsoever. Had egr cooler replaced under warranty as a recall, I change engine oil every 10k km and at 100k I changed gearbox oil. Couldn't be happier with the car.

Thank u mate . I went got a 2013 hoping they prob be great cars . But I had it week and I've never had a crap looking dash . And interer. I went b to garage got my n47 2009 sport highline back . Had service am going keep it . Interer is like limo

Even having had the timing chain done on my E61, I still keep expecting it to go ping some day.... I guess all the horror stories are hard to get over!

Loving the videos pal. I do have a case for you though. I have a 2010 318d with the N47 engine. I bought this just 3 weeks ago and I can tell you, I am really not happy. Everything seemed fine at first, and then the problems started just over a week ago. First I got an error telling me that I had reduced power. I researched why and the outcome was to do an oil change with an engine flush and replace the air filter. Back to normal for a few days. Then, last Saturday morning it wouldn't start. After ten or so tries, it started and then died after about 5 seconds. RAC has been out and gave a few ideas, EGR, DPF etc. had a code reader on and it said the egr was stuck fully open. stripped it down with the cooler off. Started to see that the inlet and everything were just clogged up to death. Egr cooler cleaned and after a soak on the egr itself, the valve was stuck open so got a new one from Lloyds. £200 later and new EGR fitted and cooler back on, filled the coolant up, inlet all off for a manual clean, all put back together but still no joy. DPF off, still no joy. went back to the drawing board and found a thread on bimmer forum suggesting Camshaft Sensor or possible Crankshaft sensor. Now, replaced the Camshaft sensor and we have a running car. It wouldn't rev above 15000 but it would idle and stay running. Changed the fuel filter, as again, this was put on a suggested list. Booked a carbon clean and when the guy turned up, we pushed the car outside and bang, back to square one. The bloody thing won't stay running again, starts and then cuts out after 5 seconds. I have a new crankshaft sensor but as you know its a swine to get to and the tiny Allen key bolt is almost rounded. Gave up and left it sitting in my unit for another day when I can come up with more suggestions. PLEASE HELP, I'm going insane

Oooh, must look out for Black Death... there was some soot on the top when I removed the sound damping... Thanks again.

280 000km now and the whole car is running totally fine. There has been no faults at all. Oil changes done by last owner in 30 000km intervalls but I've done once after 15 000km and I'm going to keep it.

Thanks George. Star man.

I have a 1series 20D N47 and heard a noise in engine thought it was timing chain but got told by the garage it’s dpf and swirl flap issues. What would u recommend mate get rid of a cheaper option if u know of ?

where did you buy reinforced intake manifold?

Regular oil change and ‘spirited use’ to keep dpf happy and its all good. The old M47 would eat its turbo and swirl flaps for fun. Good experiences don’t get posted on forums. There’s literally millions happily clattering along UK roads

Im soon hitting 300 000km with my tuned (300hp/620nm) manual 330d 2009 lci with n57 engine. Only done oil changes and changed the glowplugs. I have not removed the egr or dpf

Got 177000 miles on 2008 n47 still running good every day just had a boost leak for about a year 😂

My steering wheel has a whining noise coming from it when I turn left and right and only does it periodically. Some times loud some times quiet, any idea what it is? It’s a E92 320d M-sports 2012

I was also looking to remove the EGR system on my 57 and install blanks but I don’t know how to re-code the ECU. I understand it will generate a fault msg and also may go in limp mode.

My previous car was a well looked after N47, and now i have a well looked after N57. No issues so far... The N57 does seem to have a better reputation when it comes to cam chain life despite the layout being basically the same. Part of that IMO is the larger oil capacity, which may offset the effect of the too long service intervals.

Agree with you, about changing motor oil.. BMW make mistake with long intervals for service(oil). I own X1 E84 4/2012 XDrive 18d, 105KW/143HP with N47D20C engine. I bought car from first owner, already change chain (at 95k). Before-car was serviced on official BMW service-because warranty.. 1owner changed oil every 25k, once also 30k. Now i change motor oil every 8k, or less/do my self. Because COVID time, do short distances-oil have to be changed more often-engine will say thank you to do this.. Experience with MANNOL oil? Thanks for your time to do all those videos..

In my opinion, the oil change interval has mostly to do with how you drive the car, and secondarily with the quality of the oil. I make a point to never cold start the car unless I'm committed to getting the oil up to operating temperature. I also drive a few hundred miles with some regularity, as a diesel should be driven. That, along with a quality Liqui Moly full synthetic 5W-30, enables me to change the oil every 10,000 miles without much worry. When the oil comes out of the drain plug, it doesn't appear much changed from how it looked going in. In my estimation, the key to keeping these engines healthy is to remember that they are diesels and that it is up to you to get them hot enough. If you're just going a few miles, it's better to have a second car running on gasoline/petrol that won't be as slow to heat up. Keep the diesel for longer trips.

Very informative 👍. I have a 2010 316d with 216,000 miles on original timing chain. Would you think the lower bhp models put less strain on the chain and therefore are less likely to fail?

Very solid advice as usual George.

Hi george I own a bmw 520d 2010 f10 with 8 speed auto 184bhp . I've owned for nearly 2 and a half years . And always serviced in time but chain never . And has nearly 290k kms but no chain noise what would u say . Please give me some advice man 🤣

My 2013 f30 330d have too high oil pressure, smoke from oil cap and dipstick hole. Issue started when I put downpipe. Car burning oil which was not an issue before downpipe installed. Car just fitted with reconditioned turbo and have flaps and egr deleted. What the issue could be?

You may have forgotten, the cracking of the crankshaft itself, Rod bearings or how are they called in English, the problematic fuel pump which fails and after it's failure you'll have to replace the whole fuel system :)

A year ago I bought an x3 -08/lci with 194000 km. Now I have some 205000 km, so if I drive 10000 km a year I can drive cheaply the next ten years! 😁 Exactly what I expected... 😍

Is it a different belt kit if you have hydraulic power steering? Mine is 2011 184bhp 320d

Removing the swirl flaps won't give you less torque or worse mpg. You have to reset all adaptation values. For example the 18d models have the exact intake manifold just without the swirl flaps and they have quite the same mpg driving below 2000rpm as the 20d with removed swirl flaps

Thanks and ses you

Happy owner of a n57 with 240'000km on the clock, love the engine :D I thought the n57 engine was spared from the timing chain issue? you made me worried...

Would you recommend an egr delete/blank? Anything to worry about?

What about Vanos Solenoids do you recommend changing?

Howlong should you warm a bmw up b4 as you say stepping on the gas??????????

If I remove egr system, are there any changes I need to make to the vehicle software?

BMW 535 XD GT 2014 with 235.000 km, fatal engine failure on the crankshaft bearing, engine completely destroyed, 5k euros in reparations. I have this BMW from the beginning and all services made in time, oil & filters changed since 0 km up until today at no more than 10.000 km and still failed catastrophically, and this not the first one hear about, I have friends who also have their engines blown up at similar KM range: 230 to 260 thousand kilometers.

Hi, can anyone tell me what is the differnce between n47d20a and n47d20c?

Oil is cheap, engines are expensive, great advice

How do I find out which N47 engine I have out of the 16 and 20 ?

Are you planning on adding a catch can?

Where can i get the boost pipe?

What oil should i use?

If you have an unlimited bank account the N47 is pretty reliable. You just need to completely overhaul your engine every 12 months. So it will be pretty reliable

Just delete Dpf and Egr by softwer.Should I use 5w40 oil instead 5w30 on my F30?

Reliable? N57? What about the rod bearings?

Had a N47 for 5 years 80k miles.No problems up to 120k.Then disaster!!!!! Some idiot drove into the side of it and wrote the thing off.Drive a VAG product now.But I would have kept it otherwise was great.

I do my m47 oil and filters every 6 thou and its sweet as a nut and shes at 147 thou now 16 year old good old bus

A timing chain should last the lifetime of the vehicle. It should never need servicing or replacement

I nearly fell asleep

dont put the n57 in this video its no where near as unreliable as n47

What a terrible engine. Replace this and that... Wow! I have a BMW, but my Honda never had this kind of problems.

Poor design simple as that, we do not need to make excuses for BMW,, Stick with M47 M57, all the N series , are terrible . You may have a lucky ine fir now wait and see.
