I have an e91 320i 2011. After a 1.5 year of expluatation i have to say that it's my first BMW with no troubles. ;-)

[@jameslord8877]

First video I’ve found explaining the n43 engine! Perfect job. Cheers

[@d1and0n1y6]

Agreed

[@spelectricalservltd5959]

Finally.. Someone who knows this engine!! Great video. I now know I have the fuel injectors and NOK sensor issue to sort on my E90 320i (mental vibrations from the engine), might swap out the Timing chain as well. Expensive car to maintain I have already done the diff and electric waterpump, both failed at very low mileage. Thanks Again👍👍👍

[@leeboycharming759]

Hi mate, nice video, very informative. I only wish I'd watched this a month ago. To cut a long story short, 2 weeks ago my dad bought 2011 e90 318i (N43 engine). We took it for test drive, faultless. Drove it back home 80 miles and it was sweet as a nut. Parked it up outside the house and left it half an hour or so. Started it up, pulled it on the driveway, revved it a couple of times and it started knocking like you wouldn't believe! Initial thought was bottom end. The looking on youtube it had VERY similar diagnosis to air con pulley or any pulley noise for that matter. Further inspection and releasing the belt proved it wasnt a pully, much to our dismay. We drained the oil, fearing the worst (expecting metal particles etc, but no, oil was clean, filter too). Then when I mentioned to a mechanic friend the car had a new clutch allegedly fitted before my dad bought it he said possible dual mass? Changed the oil and filter and fired it up, the knocking noise again! Then as it warmed up... it went silent and sounded like a Swiss watch! Exactly like when we took it for a test drive and the 80 mile journey home. Then, when pushing the clutch pedal in and out and moving the car backwards and forwards, the noise became apparent again. What's your thoughts? New clutch fitted with old fly wheel? Knackered flywheel? Knackered clutch and flywheel? Like I said, it drove back 80 miles sweet as a nut. If it is the flywheel and or clutch... how many hours SHOULD it take to replace and which manufacturer of parts do you recommend? Obviously BMW will be ridiculous. I know a few people capable of doing the job, albeit a tough one. Any advice would be much appreciated, cheers mate.

[@denizts61]

I had most of the problems he discribed, i had bad injectors that caused a misfire in 3 cilinders. I did not know at the time so i replaced the sparkplugs and ignition coils, it did help with how smooth the engine was running but when the car was idling it still misfired. 3 months after that i would hear 3 seconds of rattaling when i started the car, soon after that i would get low oil pressure warnings on my dashboard if my car was reving above 4,5k after that i was driving on the highway and lost power, alot of white smoke came out of the exhaust i knew that it was either a head gasket leak or bad injectors but i think it was a combination of all the problems i just named above. I took it to a bmw specialist they took apart the engine cleaned all the oil chanals replaced the vannos, timingchain and rails, all the injectors, and all the damaged parts of the engine because i drove it with a low oil presure i also repaced all the gaskets it ended up costing me 3000 euro to fix all this. This was 6 months ago and i did not have any problems yet but this engine is a nightmare i would stay away from it. I also know some of this could be prevented if i figured out the problems sooner and took it to a garage but an engine is not suposed to fail in such way. Ps sorry for my spelling faults

[@Jastik]

Nice explanation about our engine. With 195k km my inyectors failed and i got rough idle and bad running first minutes (they were index 3 and were changed for index 11). Also chain was loose and needed to replace (tensioner and guide as well). Also changed ignition coils and spark plugs. Now runs perfect, but Nox sensor is next... This engine needs a lot of care, as well as some ista or inpa software to "read" it.

[@BMWDoctor]

Glad it helped

[@markwins22]

Great info spot on Was unlucky when i bought my N43 2and a half years ago had my engine replaced by BMW 2 years ago bought it 3 months before the timing chain bits got into the sump and engine failure BMW replaced new engine for £4.500 50% reduction thought that was great value as they said engine was 9k anyway also i replaced the nox sensor £280 oem from spain as i was getting 30EA nitric oxide catalytic converter, sulphurized codes hasnt got rid of the code but i need to do a désulfuration on inpa 70mph for 1/2 hour etc so my car has cost me about 5.5k that a grand more than i bought it for but at least ive got a new engine and ive also coded the car to the best of my ability using ncs expert etc Thanks agin for Video 👍

[@BMWDoctor]

Your welcome mate I know only too well about this engine trust me and it’s flaws it’s something we saw daily in the garage we had about 100 of them a week in

[@kaboomist]

Hi mate, do you have a link for the OEM NOX sensor? Only place I can find it is BMW website and they want £450.

[@3dScience8]

My 16th car. E88 n43b20. Bought it 7 months before with 118k km. Since i bought it (11k km) i have changed: All 3 Oxygen sensors Nox sensor Coolant thermostat Did the valve cover seal (always use reizonsil anthracite and wait 10hours - it will last longer) Changed spark plugs twice. Changed ign coils twice. Changed injectors to index 11 Cleaned vanos solenoids Changed coolant with oem bmw (not expensive) Of course cleaned maf and throttle body Reset engine and throttle adaptations several times using my Thinkdiag+ Also watching short and long fuel trims and fuel rail pressure through car scanner app and vgate pro bluetooth obd. My advice is that: 1. only ngk bkr7a-htu plugs 2. better buy delphi ign coils because the rubber sleeve on Bosch ones is getting damaged very easily. 3. Watch long fuel trims on startup and when heated at idle, 1.5k rpm and 2.5k rpm. If there is significant variation between bank 1 and bank 2 ones, then visit a bmw specialized repair center. 4. change injectors to index 11 because there are large batches of index 12 which are coming from China. 5. Clean the ign coil grounds (brown wires screwed on the engine block) using 800 grit sandpaper. Many thanks for the informative video.

[@BigHumz155]

Delphi coils are a big NO for this engine !!!

[@YusufIslam1]

​@@BigHumz155 why?

[@janek8582]

hi how did you know you need to clean the coil ground wires? i have replaced the coils and they work fine but sometimes they start misfiring. it usually goes away after some time and mostly can be felt on idle. i’m also suspecting there may be a link between moisture and this issue. could you give me some advice on this issue?

Would you recommend purchasing a 2008 BMW E87 120i? I've heard continously horror stories on forums to just stay away from it? My other option is a 2005 BMW E90 325i. I know there is a million other factors, however generally which is the more reliable engine?

Timing chain guide and oil strainer fix with oil flush. Happened to me first week I bought the car private. Oil pressure light came on, when I turn car off and on the light goes away. Did it every now and then. Diagnosed the issue and tried an oil flush first for 15 minutes. Problem been fixed for 8 months now 👍🏼

[@sem_aki]

driving an E87 118i 2007 with 155.000KM here, it's still running with its original timing chain and it just got regularly the services it needed like oil and filters. The last documented repair it had was with 110.000 where the camshaft sensor had to be replaced. Oil was changed every year between 8tkm and 15tkm Fuel usage is sitting at 8.5/100KM, I believe that it could be an litre lower but my OBD doesn't say anything about NOX or anything so Im just living with it

[@BriBri07]

After 150k kilometers you really should start thinking about your chain. I just replaced my timing chain after 110k kilometers and it was stretched almost one chain link lenght compared to the new chain. Because of that it was also a bit of timing

[@WayToManyAssassins]

​@BriBri07 is there a replacement chain kit that doesn't stretch?

[@billysargent3459]

Great info given there, just bought a 2011 318i with N43 unit for my son’s first car, 3 days latter engine seized! We’re going to pull it out and assess damage ourselves as cost of being rebuilt professionally is just more than the car is worth!

[@Framus-wm3ye]

Sorry to hear about your experience, how many miles had the car done when the engine gave up?

Have a 2009 120i N43, In the last 3 months Ive had: A new timing chain kit, new oil pressure sensor and hydraulic valve, sump cleaned out as had broken guide bits, new rod end bearings, new engine mount and mount cover. Now need a new Vanos.

[@Framus-wm3ye]

How many miles had the car done before you had these things go?

[@wachsstift7090]

Hi, thanks for this video. It is also the first good video I found on the Internet. I wanted to ask if it is a good Idea to tune this engine a bit? And when it is, where can I get the parts. I have the e90 320i with the n43 b20 engine with 170ps and whould really like it to go like 250ps if that is posible. I thought of a better air intake, a better exhaust maybe a sharp camshaft and ofcours a good tune. Thanks

Hello.. Nice video.. When i put the scanner, my car did a misfire on cylinder 1 and 4 and a problem on the oxygen sensor.... What should i do first? N.B.(new ignition coil and new sparks)

[@attilabukholcz5805]

What about carbon deposition on the inlet valves? I haven't heard if it is a problem with this engine, although it is direct injected

[@Ruby_rose191]

I have the 2.0i n43. Already had the shattered chain guides loose chain. Managed catch that before causing catastrophic damage but still have a strong smell of fuel rough idle & misfire. Nobody can diagnose or have different diagnoses on it. MAP SENSOR. NOX SENSOR Or the injectors all expensive repairs & not sure which will cure it I hate this car so any advice ?

Hey, great video! Just one quastion of n43, always use original spark plugs? Ik have bosch but they say it is not the same, thanks

huh thanks, I almost went for 320i e93 but after checking this vid, I'll pass on it. tnx again, great vid.

[@fromhungary1234]

After timing chain failure. Don’t forget to replace the oil pressure relief valve. Fitted on your block under the alternator.

[@floridah7016]

Nice video, thanx! I also own a N43 engine. Had a lot if problemen already, changed coils, injectors, NOX-sensor.. One day, i got an oil pressure warning light. So pulled over immediately. Turned out the chain tensior came out. For some reason it became loose. A random garage changed the small ring and put the tensioner back in. Do you have a experience with loose timing chain tensioners? Would you recommend changing the tensioner or is changing the ring sufficient?

[@MatiKosa]

Best advice is to change the tensioner every 80k km (~~50k miles).

[@RedlioNxTR]

Great video, very rare for someone to exactly tell my 7 years of frustration. I've replaced most of the things you mention, expect for the injectors as they're so expensive. I guess I'll have to now. 😂

My guy here shook me when i heard him say Trinidad, that's where I'm from, my dad has the only 2009 E90 320i m sport model, and tbh he isn't showing it the love it needs, he used to drive a camry, so it worries me a lot, he waits until some fault or the engine light shows up on the dashboard, that's what a lousy Camry driver does, not what a car enthusiast does, and he still takes sharp turns likes he's driving a slow ass FWD car, i told him that since it's a RWD car u shouldn't completely let off the gas, because while u give a rwd car 25% of gas while entering a turn it helps u turn sharper.

[@seanross8149]

Hey Doc, my e88 is 2010 47,000kms and I baby the hell out of it. It runs like new every day.. regularly have a local euro specialist maintain it (preventative). Any thoughts on this engine reliability when baby'd? I don't race or drive harsh as it just gets me 10km to work and back daily. I let it warm up a bit every start and just cruise in it. Do you think the engine is simply not cut out for lead footed drivers? Is it the engine being driven hard that throws all these faults or is it inherently flawed no matter how you drive it?

[@sciencegod1]

I'm curious to know, have you had any of these major problems with yours?

[@gazjacko6695]

Hi I have this engine could you help the throttle body clicking all the time at idle like it constantly trying to adjust no fault codes but very jerky setting off

[@saif1002]

If your timing rails break and block the strainer you must check your big end bearings. If they have spun then you have to change the rods which means head off.

[@Pwasercan]

Is there a way to permanently turn off the auto start-stop on the BMW 320i Coupe? The button only works until I turn off the car (with the key). Sometimes it has remembered the setting, but then I take it to the garage and when they give it back, the setting no longer stores itself in the memory. I've asked the mechanic to save this setting and he says it's not possible, that the firmware enforces it for environmental purposes. This is so confusing how sometimes the settings stays and others (maybe with different firmware versions?) it doesn't?!

What can be reason why i get micro studers about at 1800 rpm? i have n43 320i.

[@Pwasercan]

Hi, please help 🙏 BMW 320i Coupe, 125 kW (manuf 06.2008). I've had an engine failure for many years, where the yellow engine symbol starts flashing on the panel, and the car starts shuddering and the motor sounds starts squeaking and it no longer gives power properly. And starts smelling of burned if kept running. But then if it rests a few hours, most times it continues to work fine, other times the issue persists. When I took it to the official BMW service, they deleted the registers and said the car was fine. So I took it to my local repair shop. I've had 2 inyectors replaced, but one keeps failing even after putting a new one (nr. 3). Also a couple of ignition coils and spark plugs have been replaced for the same 2 cylinders. Apparently, at first the gasoline was spilling out and leaking into the oil deposit. The only TEMPRORARY fix has been a FULL firmware upgrade to the car's system. But it suffered the same engine problem again 6 months after that. This failure has happened more than 6 times throughout the past 10 years. And even when it's supposedly fixed, the motor is rough on idle and the car always shudders a bit, and when starting the motor, sometimes I hear a cracking noise like something is clashing, probably "engine knocking", which also happens when I tap the accelerator between 2000 and 1000 rpm, especially when starting to move on an upward slope, and starts smelling of burned if I do the same over and over; but the mechanics say this cracking noise and unstable idling is unrelated to the engine failure, and it's just the age of the car (2008 car). But I think it's all the same problem. The car used to be driven by my parents, who always drove it at very low rpm. But I've been driving it for 2 years at high rpms, most of the times I use gears to 5500 when accelerating, so it should not be accumulating soot inside the motor. I've asked for a motor cleaning, but the mechanic said it wasn't necessary on gasoline motors. I did have to replace my NOx sensor too last year. I have all the problems that were mentioned in the first few minutes of this video 😥 I don't know what to think, this seems like there is no solution. Can I put a "compatible" motor into this car from another brand or even a better one from BMW?

[@letsplayagame83]

Hi BMW Doctor I have this engine and I m struggling to diagnose a problem. The car runs smooth but once I accelerate on the motor way check engine will come I scan the car it will give me Lambda sensor bank 2, mixture control and NOx catalytic sulphur I changed the NOx and the Lambda bank 2 but still having the problem Can you advice on that please

Berrings not damaged as car wasnt run seems to have occured on start up rattled and immediately stopped, 135k on the engine well serviced approx every 5-8k, chain was replaced as a precaution there was no issues with it. broke one pump before chain replacment one few weeks after.

Hi Doctor, all what you mentioned is correct. I have 118i with N43B20A and fortunately in mine the injectors were changed still while on warranty by the dealer. The car is owned and used only by my father since new and has done only 30K miles. It's well maintained and oil changed frequently minimum once a year. Now unfortunately I definitely need to change the NOx sensor. It now was already verified so we know it for sure. I don't want to buy the one from the dealer as it is so expensive. I would like to find some proper one equivalent from other manufacturers. Should I buy the complete set sensor with electronic box or can I only buy the sensor itself and connect ti my electronic box which is in good working condition. Please advise which sensor to buy and where I can buy it, the relatively good one and reliable. Please help. Kind Regards, Mike

@@sciencegod1 after I bought it and spent a good amount of money on some known issues, it holds ok. I’ve driven 40.000kms on this car which now stands at around 175.000km, oil and gas consumption went up (clogged catalytic converters from burned oil), 2 of the ignition coils went in a better place while driving at the same time, some of the front end steering parts failed but is normal wear and tear.

for me when I was traveling sometimes there was a warning / oil pressure engine failure ..etc / when I stopped and restarted the engine disappeared and then appeared after a while / after a few months I decided to change an oil sensor and another oil probe are all on the side engine block and very difficult to access! / then I put everything back together and the car went well and the error in the diagnosis was definitely gone! so two new bmw parts (£ 130) but the small oil sensor was very hard to remove because the plastic broke on the outside 😆, but I managed after a few hours 😅 / good, fun !!! 🗽

Hi. I got the E90 318i, N43 engine. Sometimes I get a fault code (2A99) and makes the car sound like a tractor as the rpm goes up. Then the fault code comes up it makes no sound, but it reduced the engine power. Its been like this for a long time now, but I cant figure it out. I’ll be pretty thankful for help. Thanks

Great Video mate!! Got the same engine for a year, got the same problems, replace the injectors and runs better now but sometimes the check engine light comes on, after a sport drive on motorway, about 30 min goes off. No difference on the engine when the light is on, runs the same. The tester said that the catalytic convertor is clogged. But anyway, is a great engine if you take care of it. My one have 193k miles and still purse like a cat 🐈

how does your intake manifold look like ? Mine was super greasy and led to carbon buildup on the intake valve stems. May have been oil seperator failure on mine.

I have a BMW 318i n43. I have had the timing chain changed by BMW dealers. A few months ago I had a fault come up stating that I had to stop the car and get help,also brake load fault. I go the AA out and he said that a nox sensor fault came up saying something about regeneration. Any idea what it could be?

After timing chain, the engine was shaking like crazy sometimes. For me it was either the exhaust or intake camshaft sensor, can't remember which. They're cheap tho

So for a 316i/318i buyer looking at the E90 (and used to E36 simplicity!) where am I supposed to turn? All the mistakes made on the E46 seem to be worse instead of better. ☹

[@petrinieminen7353]

E39. Similar size, worse fuel economy but makes more than up for it by vastly better reliability. Also nicer to drive, quieter and more powerful than N43. Just don't go for an automatic, it makes the whole thing thirsty and the GM automatic is also rubbish in reliability. The ZF one is good at least at that.

[@hunbrian6138]

Hello. I saw your video now and its great. English is not my language so it was a little bit fast to me :D amazing knowledge of BMW engines. I have this engine and I have the vibration problem when engine is warmed up. When its cold there is no problem. When engine reaches higher temperature the idle speed is decreased to 650 and starts shaking the engine... If I let the engine at idle for long time then it turns off cylinder 1 injection. I delete the fault code -29CD - the injection turn on again in cylinder 1. I have only one fault code is on alltime: 2EF7 thermostat. Is here any relation with it? Anyone who has any suggestion please? Why happen it at warm engine? I replaced ignition coils, and plugs. Injectors are originals. But I really dont understand if I have an injector problem, why arent there fault codes or engine light, and why not faulty alltime? Please someone help me. I write here because here are many people with experiences about N43. Thanks a lot guys!!!!

[@vitogomes8365]

Great video! I'm italian and I'm temporarily living in USA. I decided to bring over my 2007 BMW E93, with the N43 engine (now 80.000 km). Since my car landed in USA I started to have issues: first the four ignition coils, second an engine light due to the nox sensor (that I didn't replace) and then, after a year, the four injectors (seems that the engine light triggered by the nox sensor doesn't show up anymore, after the injectors have been replaced). I've always been sceptical about the gasoline quality over here, even if I've always used the highest grade, the 93. Do you have any suggestion on how to survive here at least for another couple of years? Any precoutionary measures to be taken? Thank you very much!

[@Pwasercan]

same issues here with NOx sensor, injectors, ignition coils.. no permanent solution found yet :(

[@petrinieminen7353]

There's a reason why these vehicles (BMW with N43/N53 engine) weren't sold in USA at all. The NOx cleaning system just can't take the sulfur levels of the fuel there.

Is this engine also in the BMW 1 series 118i convertible from 2010?

[@chrismccotter3061]

Great video mate one quick question does the NOX sensor need coding when its replaced. thanks in advance

[@BMWDoctor]

No you don’t need coding it’s not that special of a engine

[@StefanTomic]

You need coding, in order to reset the adaptions from the old sensor. That way ECU will know there is a new NOX sensor, which will also affect the engine performance (positively).

[@mmlj2140]

Thank you very much ! I have a 318i from 2009 with this engine. I have a plug unplugged but cannot identify where it goes... located at the rear of the air intake manifold... Would you be able to help me ? Thanks !

[@petrinieminen7353]

3,5 years with E91 LCI 318i and I've really had enough. I do only 5k miles per year on average and the sodden crap can't manage even 8-9 months without having something broken. And no, not due to poor maintenance, I've always maintained my cars very well and frequently. E.g. oil change every 4-6k miles with high quality oil and fuel system cleaning with high quality fuel system cleaner designed for direct injection in this case. In 3,5 years and around 16k miles (from 109k to 125k miles) having to do the following repairs (besides the usual maintenance): - 4 new injectors, á 400 € - 4 new ignition coils, á 30 € - One new A/C pipe, 250 € incl. emptying and refilling the A/C - one broken ABS ring, 50 € for the pair of sensors and rings - one blower motor, 80 € - blower motor frozen solid (yes, the new one!) every winter starting from -15 °C down - camshaft position sensor, exhaust side - desulphurisation of NOx sensor, fortunately have managed by driving, no new sensor needed YET - thermostat housing, the old one had cracked, 0 € due to happening so soon after buying the car from the dealership. Summary: If you want a reliable car, stay away from this heap of junk.

Hey guys. I have a BMW 2011 318i E90. Recently after driving it i noticed a red engine light half filled in appear on the dash. I got the car scanned it came back to be a engine oil pressure control static code. Prior to this recently i did top up the car with 5W40 as it was low by a litre or so. I have a leak at the oil filter housing gasket next to the oil cooler. Has anybody else experienced this problem similar to mine and if so how did you fix this issue ? Was it because of the wrong grade of oil used or becuase of the leak at the oil filter housing ?

[@romaniantech]

hey, while I did not get the engine light I do get the oil pressure static code from time to time. I also have a rough idle once in a while and I am also using 5W40. I bought a new OE 11417584990 hydraulic valve but did not replace it yet, together with the oil filter & oil cooler gaskets as they are also leaking. Did you find a fix for your issue?

You have a vacuum leak somwhere. Go to a service.

[@drazenivanda9514]

Been running this one (n43b20a) in my 320i E92 for some time now (1.5yr), already done my coils (4), sparks (twice), vacuum pump, noX sensor and some cover gaskets. Other than that, it runs really well and doesn't sound that bad at all - at least while driving. I get around 10.5-11.5 litres petrol in the city and around 7.5-8 when out. Still running on the first timing chain tho, now at 220.000km, replaced the tensioner with a newer one (last revision), but I'm planning to do a full timing chain setup brand new this year as it's not that expensive when buying parts yourself and doing service somewhere else instead of the dealers. Two things annoy me the most about this engine, okay - three. 1st - lifter tick, no matter what you do, how you drive it or what oil grade you use, that clicking sound will get you, 2nd - I sometimes get a red oil pressure light although the oil is on max, no codes, and the timing chain isn't to hear from at all, I guess the oil pump is planning to say something to me pretty fast, and 3rd - the engine runs rather hot, so you better check that coolant level and quality regularly. I mean, I don't really find it that notorious at all, at least when compared with a N47, and oil changes between 8-10.000kms, it is really possible to run on first chain even on high kms such as 200.000+.

Hard to believe some of the comments on here. I'm certain many of the haters are under 30 years old and bought the cheapest oldest E9x or 1 series BMW with the largest rims, did not check its maintenance or history, and beat the hell out the car , only to then complain that it leaks or misfires... When I see N43 cars for sale, you can tell what kind of owner are selling them, cheap budget tyres, DIY repairs, non genuine parts, and all the rest of their 'maintenance' is spent on LED light or 19 inch wheel upgrades ...it's no wonder why the 15 year old engine gets a bad rep now...
