Quick Summary 1) Oil cooler housing gasket 2) Oil filter housing cap 3) Tensioner, accessory belt and idler pulley kit 4) Charge pipe (better to upgrade to aftermarket) 5) Valve cover gasket 6) Ignition coils & spark plugs (if remapped, run colder sparked plugs to prevent problems) 7) Vacuum hose (locked on to vacuum pump) 8) Crankcase ventilation hose (good to replace if replacing valve cover gasket) 9) Vanos solenoid 10) Thermostat (& water pump, coolant leak is a big sign) 11) Rod bearing 12) Carbon buildup

[@kjhnsn7296]

Other than the rod bearing and vanos, seems like normal wear and tear stuff.

How many miles now? I’m looking at one with 67k miles. M-sport for $21k. But I drive a ton, 20-25k miles a year (mostly highway) so I’m wondering if I should avoid simply due to how quickly it will acquire miles? I can perform a lot of maintenance myself. I really wanna get into a car I can actually build though and I love this platform for the money.

[@Jeffc288]

What’s the hose on the left side of the engine that’s wrapped in the silver heat wrap? Also, what’s the sensor that’s below that hose? I think mines leaking. I keep getting oil on that silver tray looking thing on the left. However it doesn’t seem to be my valve cover gasket. One more thing. What’s the hose that’s tucked up above the engine below the windshield cowl?

[@oleglakhno]

do you hear about oil pump failure? Is it need to be replaced on some specific mileage? thks

[@turbo97semax]

Thank you for the list here. I replaced everything you listed here on my son's car except rod bearings (I probably should have since I had the oil sump out to replace the gasket), and more as preventative maintenance. I replaced the engine mounts, charge pipes to all aluminum on boost side as well, the water pumps can now be bought with aluminum housings so should last longer, I replaced the entire valve cover. Also the oil level sensor went out and oil pressure control valve (near the vanos control valves) seems to be a bit dodgy occasionally giving me high pressure oils codes, but no check engine light). front main seal would be a good one to add to the list. I did not do it but it will fail. I also had to replace the injectors and code them. I think someone had replaced them before and did a very bad job replacing them because they were not even coded with the correct offsets. Also the radiator hose inlet at the front of the engine is made of plastic and completely disintegrated when I pulled on the hose. I replaced it also with an aluminum one. In good healthy condition, these engines really rip! I am definitely not afraid to work on these engines anymore!

[@zeroatomfault]

Just moved from a 320i to a G30 530d. Loving the power and sweet purr of the six-pot. Any tips I need to know about to maintain her in the best condition besides changing oil and filter every 10K miles? (I don't trust BMW's Loooong service intervals). I hear the B57 is pretty solid and reliable, I'll be keeping this one for as long as it lasts or they force me to buy an electric.

[@moealudimi143]

Change every 5,000 miles 3,000 miles if you really want to baby it

[@Scotford_Maconochie]

10K miles is too much for oil changes. 5k at most and use an oil that is BMW LL12FE+ approved or BMW LL04. Service your transmission at 50k to 70k miles with a new pan & filter and ZF Lifeguard8 fluid. Service your differential(s) and if you have xDrive also your transfer case. Glow plugs and modules

[@BMWI-gk9wh]

Don’t DO 10k miles oil changes crazy. You trying to ruin your engine??? 3.5-5 k max MAX.That is the issue for the people maintaining the car. Get on the forums and learn. Everybody in these cars know not to push oil change past 5k! Got to keep fresh oil on the rods and ⚙️s. This one step will save your engine. Aslong as it was done from the begging of the n55s life the engine will last a while! Have over 264k miles on my n55 335i 210k miles on my n52 328i 200k on my n51 328i 120k on my n55 e90 335i

[@andreiqwerty5190]

I have a problem on my N55 435xi at cold start, RPM is going up and down fast, sometimes engine shut off. The problem is sporadic ( i suspected fuel pump, fuel which is 95+/100, coils even injectors ). Diagnostic is useless ( no errors ). After first 10 sec of coldstart it has no problems anymore. Do you know about this? Can you suggest what i should do?

[@user-db2du6kx7s]

overall good video, thanks. One thing you can improve is to put list of parts you prefer changing on the car, for example spark plugs. COLDER spark plugs for example ;)

[@andreybanchev4763]

Maaan... All this sounds so reliable! No issues at all. Almost like a Lexus engine.

[@Pseudo_Placebo]

On my N55 after 8 years the first defect.... only when the engine is cold and after starting, the part shakes and shakes as if it were only running on three cylinders, tries to catch itself again and again, but basically almost sinks if you don't counter it with some throttle. However, as long as I keep the revs right at just over 1000 rpm for about a minute or a minute and a half, the engine then runs normally at idle and absolutely smooth. With your experience, this is surely a known problem and probably not a big deal, right? am grateful for any help🙏🙏

[@benjaminyosfan7756]

Great list and right on the money!! My 2013 F30 has 106k miles. At 105, valve cover leaked as advertised, replaced the whole cover and gasket since the PCV is integrated into the valve cover. While it was open, had them replace the plugs and coils. My charge pipe blew at 90k miles. Probably mentioned earlier, but the tank to radiator hose will be brittle at 100k. The 90 degree bend at the radiator will crack and blow hot coolant all over your engine. 5 minute fix. My broke at 102k Cheers!

When your charge pipe blows, are you able to keep driving home/mech easily enough? Or does that mean tow-truck time?

Hi Great Video.. it astonishes me that BMW has lots of issues.(and continues to still have them) I have a 2013 x5 35i and i has been fiddling with vehicles all of my life, i purchased this vehicle last year,Why BMW has not "ironed" out these common issues with their vehicles is beyond me.... (at least especially their Gasket issues/belt,crankshaft cover/etc, like why not (bmw engineers) go to a company that can make a gasket without failing..I mean a Human can put a spaceship on the moon and cannot manufacture a reliable Rubber Gasket??.. i had a toyota highlander with 400 thousand and it never leaked at any time and less issues...BMW is suppose to be a "top of the line engineering...BMW Engineers need to get their act togather.ty great explanation sir 100-100

just do occasional old oil lab samples. that way you can do the rod bearings as prevention from any issues, bc it will happen eventually unfortunately it seems. ive even see n54's here and there. turn of the auto start/stop, and install a proper pcv valve and a catch can if you get on the car a lot.. cuts carbon by ALOT!

I just replaced the whole engine from 2017 bmw x6 into 2011 bmw 535 xi some changes on setup since it was from 2017 with a EWG setup it took a little time to get it done properly because mine is PWG setup ECU and now have ZERO hedache on everything worth to spend on the engine upgrade

[@davidburton7403]

Just bought a 2011 535i and can’t wait to get up to date on maintenance. I can’t do them all at once so are there any key specific ones to do right away. I’m trying to maintain it before the parts do go out

[@RexNathanChan]

None of the common N55 failures are maint (oil/filter, plugs, belt) related, but seem age/heat/time related. SO just check for leaks and expect things to go wrong eventually (electric water pump is the main one that worries me, the others won't lead to engine failure).

[@EvilMmM]

so how to prevent that from happening? what should i do/buy?

[@Marcohhh]

i’ve been watching you for a while now, i’m actually getting a 2013 335i this weekend, with 75k miles. do you think it’s a good choice and also any common issues that happened during the manufacture of the 2013 n55

[@RedLine_90]

Hey i am looking on buying one with around 65k miles also. How is it going with the car?

[@175dell]

I got a 2013 335ix with a 6MT. I love it. I have about 120k more miles on it than you do on yours. haha It's been great. A big thing is to keep on top of maintenance, I do oil changes early, keep on top of oil leaks, and upgrade the charge pipe. Also if you have any service done requiring opening of the engine or oil cooler lines make sure the oil pump is primed! Indy mechanics may not know to do this. Its easy and is cheap insurance. Best of luck!

[@jjaimep]

My F30 N55 is now at 149k miles and is pretty solid. None of these parts have failed, but I did change the valve cover when I had the chance. It's plastic, so it will need to be replaced periodically. Some common sense and good maintenance and these can last you decades.

[@Anythingyoulike2013]

Got my 640i LCI at 98k miles last year, now at 118k miles, only thing I've done is the small pcv vent hose £40 (old one cracked), and recently had drivetrain malfunction for the first time ever for the electronic wastegate actuator not closing fully (ive got ISTA) - will try recalibrating, failing that will replace the EWG. Thankfully EWG options are good, Honeywell make one for about £100, genuine BMW is £280ish. Other items - front brakes and discs done, and oil change once. I am losing 1 litre every 4000-5000 miles which is totally acceptable, for an I6 BMW, lol.

[@Damien911]

Glad to read this I also got a 640i with 58k miles 4 months ago and I was a bit worried when I saw the video, I didn’t knew the Lci one were still EWG. I don’t know if doing the road bearing is worth it considering it can damage the engine or maybe it’s not worth it at this mileage, very happy with that car fun to drive despite its weight thanks to the adaptive drive and excellent car on motor drive as well. Any issues with the charges pipe ? Some failed around 60k miles

I have been having issues with a P Code P0222, Throttle Body after I replaced my HPFP. The Car starts and I was driving it with with Reduced Power Malfunction Check Light . Took it to the Beamer Shop and they went into the dreaded BMW diagnosing Rabbit Hole. I was first told it was HPFP , then the Throttle Body, and lastly the DME. they pointed to the DME located on the Passenger Side.

I got a 2011 335i n55. It was in horrible shape and I needed to do a ton of work on it. I replaced all control arms, bushings and ball joints along with putting in bc racing coilovers. Then I had to replace some coolant lines and the radiator. New valve cover and gasket, new vanos solenoids camshaft position sensors and now I still have check engine lights. I'm currently ordering a throttle body, ignition coils and plugs. Oh also I am using a sensor bypass kit for the passenger seat occupancy sensor. I plan on taking the headlights apart and fixing the broken hardware and motors because one headlight points down.

I’m on 150,000 miles and I’m now going through most of the problems you have listed. The valve cover, I have the gaskets replaced and the cover is ok. I’ve heard that the diaphragm can be replaced without needing to replace the whole valve cover, is that true and can you recommend a part?

[@abradberry]

It can be but I’ve only heard of it lasting a few months before the part fails,so it’s best to only use as a temporary fix

[@Areku06]

It’s pain to do that, better to replace valve cover

[@175dell]

So far my high mileage n55 has been reliable, however I'm a huge proponent for preventative maintenance. If you do your own work and do maintenance early, you will have very few issues for a relatively low cost. I wonder if the rod bearing failures could have to do with people not priming the oil pump after service involving oil pan gaskets, oil filter housing gaskets, anything involving oil coolers, ext. BMW didn't have that service bulletin to prime it in the early n55 days. It's cheap insurance that you won't starve your bearings of oil.

[@spacederp4120]

this is exactly what happen to my 2011 335i bought it 3 months ago and now I'm in a full engine rebuild cause the previous owner didn't prime the car after the ofhg wish I had realized the issue sooner

[@175dell]

@@spacederp4120 ohh man, sorry to hear. I hope a rebuild isn't too pricey compared to buying a used engine. A lot of people these days go the used engine route vs a rebuild. Gotta love how BMW simplified the n55 oil passages to increase vanos reliability but caused a different catastrophic problem even worse than the issue they were trying to prevent 😑

[@ChristopherGuilday]

Do you have to prime it after doing a regular oil change & filter? I didn’t know about priming it when I did my first oil change on it. I’m assuming you don’t, but I’ve heard some people say you should. Your thoughts?

[@BenefitExploits]

@@spacederp4120 What do you mean by priming the ofh? Just fill it up with oil when replacing the ofhg?

[@175dell]

@@ChristopherGuilday I'm not sure, I don't prime the oil pump after an oil change. I've read some do as well. I've done about 6 oil changes (5k mile OCI's) since I've had the car, no issues so far. I generally don't let the car sit for too long between it's last drive and first start after the oil change. Could have something to do with it. The main thing is to make sure that plastic bird cage looking piece stays in the OF cap and doesn't get thrown away by accident, sometimes it gets stuck in the old filter during removal. I would prime it every time if I didn't have to unplug 6 brittle injectors every time. Haha

ok , my 2013 535i’s engine went out because previous owner sucked at maintenance so rod bearings didnt get enough oil, so you should be good if maintenance on ur car was truly kept

[@BeanieNinjay0]

N55 has a forged crankshaft?

[@mikeguzman96]

HAVE A 2012 335I, RECENTLY CHANGED WATER PUMP AND THERMOSTAT AT 86000 MILES ALSO REPLACED CHARGE PIPE WITH AFTERMARKET ONE(VSRF) CAR WAS DRIVING GREAT. AFTER 10 MILES GOT REDUCED ENGINE POWER. WENT AWAY FOR FEW MILES CAME BACK. 387F POWER MANAGEMENT, CLOSED CIRCUIT CURRENT VIOLATION. 29D0 INTAKE AIR TEMPERATURE SENSOR, ELECTRCAL SHORT CIRCUIT TO BATTERY POSITIVE. 29E0 CHARGE AIR TEMPERATURE SENSOR, ELECTRICAL SHORT CIRCUIT TO BATTTERY POSITIVE. 2D60 VANOS, EXHAUST CONTRO FAULT, CAMSHAFT STUCK. 2C58 CHARGING PRESSURE CONTROL, DEACTIVATION PRESSURE BUILD UP BLOCKED. CODES I GOT FROM REDUCED ENGINE POWER. ANY INFO WOULD BE GREAT

[@BMWDoctor]

That sounds great 👍🏻 hope your enjoying the car. And get it sorted soon

[@Scotford_Maconochie]

The N55 that was in my 2013 X5 xDrive35i experience the following under my ownership. -Oil filter housing gasket failed -Coolant overflow tank failed -VANOS solenoids failed -Valve cover gasket failed -Oil pan gasket failed -Vacuum line tear causing boost leaks

[@ArisFilms]

what were the symptoms before you replaced your vanos solenoids? Also which vaccum line did you replace

[@Scotford_Maconochie]

@@ArisFilms for the vanos. Hesitation on throttle, jerking, fluctating idle and i once stalled when leaving my drive. The engine shut off as i was pulling out. For the vacuum line i beleive it was the one for the boost pressure controller.

[@cac3994]

Fir the Vaccum lime tear what were the symptoms?

[@Scotford_Maconochie]

@@cac3994 loss of power when the boost kicked in c. 3500-4000rpm. The vacuum line fault would prevent the waste from opening.

[@175dell]

Yeah those are all the usual suspects. That oil pan gasket replacement is no joke. I did it myself on jack stands in my garage for my wife's n52 and on my n55 within a 2 week span. It was terrible. But I saved loads of money and drank lots of beer.

[@N5XBEVST]

Is it okay to run colder step spark plugs with out a remap ?

[@jonn9103]

Not advisable as you will likely get crappier gas mileage and need plugs changed more often from the excessive carbon build up on the plug tips.

[@GIBSONSGAMING]

Time to do mine then

[@_Wai_Wai_]

I have fault Codes P052 and P054 for my 2011 535i, N55 engine. The Engine runs bad.... Kind of stop and go Idle, with some knocking noise. I cleaned out the VANOS solenoid valves, but I should have checked if the electrical connections of those VANOS solenoids is faulty or not. Not sure what else to check.

[@ipodTouch4g07]

Great video ! What do you think about oil catch cans ? Is one needed for the N55 ? I bought one and I still haven't installed it yet.

[@richardtrow2751]

It's a definite advantage having an oil catch can on direct injection engine, I've had one for a while on my M135i and it definitely catches oil which would otherwise be going in to the intake and onto the back of the valves 👍

[@zychrias]

@@richardtrow2751 which one did you get? I just got a 14 m235i

[@jonn9103]

You will likely barely find anything in it. N54 it is supposed to be much more advantageous.

[@Heavlysedated]

I sold my f30 335 x like he said. Problem. Problem . Problem . Problem. Mine was non stop over 10k in maintenance

[@user-bn7ek9dr5y]

If you have a E9X facelift an F series BMW with 35 badge 40i for the F version of the 7 series you have the N55 engine and the facelift X5 E70 have it too!!!

[@BmwMe-uh9sy]

2010 e90 was facelift and came with n54

[@pesbmw1028]

Thanks for you Can you helpe me My car 535i f10 n55 engin link oil from brake vacuum on valve cover( boost solenoid )

[@pesbmw1028]

The oil come from valve cover to boost solenoid

[@jbird3788]

If I change all these parts at 100k miles. How likely is it that these cars car run for another 80-100k?

[@orange6265]

very

[@Saltygarage]

I'm having an issue with me 2013 135i n55. It's only making 3-8lbs boost. Breaking up under load. What are the possibilities, I've checked for boost leaks, seems to hold. I'm thinking maybe vacuum? It rolls into boost but won't hold it .

[@usa1144]

What motor is in the 3.0 2013 535 I? Is it the N55???

[@PetriKekkonen]

N55

[@CBR125er]

M235 2014 N55...100k miles and no issues

[@feloflox4603]

From which year was this engine improved

[@TreySoSuave]

13+

[@Scotford_Maconochie]

In July 2013 BMW upgraded the N55 with a slightly larger turbo and a electronic wastegate.

[@Scotford_Maconochie]

My 2016 built N55 has 100k miles now and the only 2 problems I had were the water pump and the thermostat. The VCG, oil filter housing gaskets and oil pan get regularly checked for oil leaks and they're all dry. I keep my oil changes to 5k miles and only use Pennzoil LL-01 5w40 unless it's winter. Seems it helps preserves all the gaskets plus zero oil comsumption in over 60k mi !!

[@up-allnight]

Congrats on your good run. I hope my n55 treats me just as well. How do you feel about the liquid molly oil?

[@Scotford_Maconochie]

@@up-allnight personally I don't see a significant benefit using Liqui Moly or others since my OCI is 5k mi or 6k mi maximum. Liqui Moly is not readily available on the shelf where I live but Motul is (Motul Specific BMW LL-01 FE 5W30, Motul 8100 X-cess gen2 LL-01 5W40 and Motul 8100 X-max LL-01 0W40) are all top choices for an N55); typically I alternate between Pennzoil Platinum Euro, Castrol Edge and Mobil 1.

[@_Wai_Wai_]

Is the F10 and N55 the same thing?

[@Scotford_Maconochie]

The F10 is a chassis code of the 5 series for model years 2011-2017. The N55 is an engine produced between 2009-2018 and found in many different models including the F10

[@cheezybread7783]

could u make a video for the B58 engine parts that fail as well? thnx

[@BMWDoctor]

If I did that it’s going to exceed the 30 things on this due to new technology I think it would be 60 things that will fail on the B58 that’s why I haven’t done it terrible engine terrible reliability your better off to buy a Porsche just like I did could have bought many of them 5 times over but I invested into Porsches not a car that devalues because there shit boxes

[@cheezybread7783]

@@BMWDoctor isnt porsche more expensive? But I though BMW inline 6 engine blocks are strong...? I was thinking of getting one as a toy for weekend or summer. Would u recommend E90's?

[@BMWDoctor]

Of course porsche is expensive it’s meant to be but if you manage to get into that manafacturer it means you should have money for all the parts needed when it comes up. Personally I wouldn’t drive any of them due to the fact they ain’t a power car or a sports car they are just a luxury sedan with power but not built for racing or track from factory. It’s up to you dude personally I wouldn’t buy none of them as I have zero intrest in BMWs. But everyone to there own choose wisely and choose what you will be happy with most importantly choose something you can afford

Literally changed all of these. Valvetronic is one you've missed.

[@HChristoffer]

Yup, the valvetronic motor is the only thing that faild on mine... so far.

[@xample2x143]

where is the high pressure fuel pump ?

[@thomastrinkler6055]

Boost pipe has bursted at 120k km. Although my m135ix was tuned to 400hp🥳

[@thomastrinkler6055]

I replaced the original boost pipe eith an reinforced aluminium one

Good to know that BMW didn't design their plastics for above stock power.

[@uchiha_d1334]

[@etienlemut1777]

So you probably bought this engine instead of the B58, because the B58 has the timing chain in the back of the engine?

10 Parts .... all parts that are removable and replaceable from your own drive way........ 10 parts!.... people Complaining 🤦‍♂️. 100s of other parts that are not accessible at all in your garage/driveway those 100 other parts never break! And never have to deal with... everything listed is simple and takes under a hour to do yourself! I love these cars. Very reliable if the car has been taken care of correctly and not necessarily on BMWs intervals.... change your own oil at 3.5-5k miles from the beginning and your car will last. Replace most preventative maintenance parts yourself and your car will continue to run for manymany years. My n55 has 280k as we speak with stock bearings. All stock no maps. My n54 has 170k. No issues My n52 has 230k no issues. My n51 has 190k no big issues (secondary air).

[@MrTrdiff]

First couple of miles when cold driving low rpm a very loud ticking noise , goes away once warm , injectors ?

[@BryanChance]

Auhh.. it's the same things on any BMW. LOL #1. oil leaks from anyplace there is oil. That's why I love BMWs. And things could be worse, like Audi.

[@RandyNguyenProductions]

BMW has great suspension and awesome handling but they've failed on Engine built and design, they need to RENEW the Engineer Team and improve the Ultimate Driving Engine. Imagine an Engine that has a long list of problem is very ridiculous, what's the most important in a Car ? an Engine right ? but all BMW 3.0L Engine has problem with Rod Bearing and all gaskets, VANOS and Tensioner bolts ? and chargepipe ? They blamed driver for not changing engine oil that's why it caused Rod Bearing worn out ? that is BS, i dismantled N55 Engine took off the Rod Bearing and compared with Lexus 3.5L Rod Bearing and see that BMW 3.0L Rod Bearing material is CHEAP, and BMW used most cheap materials in their Engines.
