280k miles (450KM) on my 330i. Regular oil change intervals and the thing still sings all the way through the rev range. I couldn't be happier!

[@jequitygroup4108]

Wow!

[@DavidSmith-wr6vj]

My 330i with 113k must be just a we baby then

[@80s_Boombox_Collector]

My issues with my 2006 330i (all happened between 90-120K miles): 1) Cracked head bolt (!!!) causing a massive oil leak. Bad metallurgy or factory torque setting. 2) 3 cracked bolts on the oil pan, causing another leak. Another factory defect. Big $$ labor cost. 3) Cracked bolt on the tensioner. 3) Valve cover leak. 4) 3 failed ignition coils . 5) Failed AC compressor .

Im on the verge of sellin mine cuz of its miles :/

[@kamata93]

Thats a bit weird. On the forums in my country the N52 is being hated because of the excessive oil consumption and the vanos issues. N53 seems to fix the issue with the oil consumption. Yes, you have the issues with the injectors and hpfp but it seems better overall.

Just drove from NYC to Detroit and back in my 2011 328i manual. The engine just got smoother and smoother as the hours passed. It was really a joy on a long journey!

[@kevinlowry7608]

How many miles on your 328 buddy. Thinking about buying one over the 335. It’s a 2011 also

[@gilgonzalez5902]

@@kevinlowry7608 with the 335 you have to be careful because the N54 was not very reliable and neither was the first year of the N55 (2011) so if its not a 2012 and up 335 then id go for the 328 which is EXTREMELY reliable albeit less powerful than the 335.

[@davidmoore3313]

I'm a proud owner of my 2011 328i E90 N52...owned it for 4 years now has 113K original miles runs strong. Low maintenance costs. Changed out the plugs, coils, filters, radiator, regular oil changes, and literally no major issues. As long as you keep everything to spec on fluids and do the regular maintenance they will run for the long haul. Great video! 👍

Thanks Dean, I got a e60 530i n52k (Aussie) for (Aussie) two years ago, 272bhp, 2008 LCI. It’s taken time to work through everything, including the gearbox sadly, but she finally feels new again, pulls hard and really, getting close to original performance for less than 20k it’s an absolute steal - still cheaper than the second hand Ford Focus St that I went to look at and is a much nicer car in every way. Your tips have been super helpful too!!

[@readytom123]

I recently bought a sedona red 125i, loving the n52 so far, its celtic tuned to 280ish, its been a joy so far. Its in getting a few common issues preventatively fixed (replace the silly plastic valve cover, breather pipe and gaskets), all relatively inexpensive. These n52 videos gave me the confidence to sell my much newer bmw and go back to the beautifully sounding NA 6cyl. No promises that i wont supercharge it though haha!

[@TheGarage2018]

I have to agree with you Doc! I have an E91 with the N52 and I love it to bits! “Pulls like an animal” lmfao you made my day!

[@wjohnsonism]

I have had the M54, still have a N55 and S55 and love our N52. I bought a 2011 328i with a N52. Put $800.00 in refreshment parts including oil pan gasket, vanos solenoids etc, and its the smoothest, best running engine I have ever diy'd on. So much so I'm looking for another 328i with the same engine as a backup.

[@nastyresidue6772]

I know it’s been like a year, but where did you get your oil pan gasket?

[@hossrc420]

Im glad I chose the right bmw when I got mine. I scored a 2008 125i m sport with the N52. Your videos have already helped me sort out some minor issues with it. Good work buddy.

[@balnsingh4118]

Bravo 👏👏👏 well said Doctor Dean. Now people's are gunna realize what a quality performance engine this was after all... It ain't no sleepa anymores!! Smooth as silk & quick as you want it to be if needed, & no turbo shite just good mechanical engineering. Keep up the good work Doc.

[@a9653192]

I do love the simplicity and reliability of the naturally aspirated engines. I guess I just ended up being a lucky guy since I have an N55 engine F30 series running strong at 80k miles, I will say I did replace a lot of the plastic bits to aluminum before they failed... I’m now watching for my oil filter housing gasket and the dreaded electric water pump and thermostat...

[@kevincaughlin8781]

The M52 and M54 are also out there to pick up for very little cash. I've seen E-39's disappear from used car sites here in the States. Same benefits; naturally asperated, good power and long life if properly maintained.

[@alien9114]

Yea, and don't have 300$ water pump

[@jaymum23]

E39s are getting rusted out and/or totaled plus owners of the survivors in good shape know what they have and are keeping them. It sucks how hard they are getting to find. I need to get my hands on a 530i sport eventually. I had a 525i 6 years ago and only wanted for a bit more power, like my current E90 330i has. An E39 530i and E60 530i/528i will be in my future barring some financial disaster.

[@robineccleston6083]

love my N52 126,000 and purrs like a kitten no leaks at all. Since lockdown I have done all shocks struts coils, complete rotor and brake job. new rims tires and redid the exhaust, went LED on headlights. Car is cherry, I am only owner, drives like the day I bought maybe even better. Have always done regular maintenance. I will say it needs a paint job, still looks good from distance (Like I used too) but up close see a lot of chips and dings in paint. Lots of highway miles. Almost forgot I have no nav system, So ripped all audio out and replaced with 8' pioneer Digital media player and JL audio for speakers and subwoofer rocking down the highway now. A big shout out to dean for his great videos and passion for his bimmers.

[@benmanis8660]

I’ve seen my E90 go up in price since November. I traded my car with cash on top for a salvage title front end damage not past radiator support. Dude had it up for 3k no one bought it. I did a hood, grill and bumper for about $550 and now people offering 5K low ball on this car and it’s salvage title. It’s crazy. Love my n52. Drives so good and smooth.

Ultimate driving machine!

[@evanasche8882]

Of course I love the N54 but the 328xi with the N52 was my first experience with BMW and that engine and car is what made my love for BMW concrete. LOVE these engines! (Also I got an rx7 fb and are currently measuring the engine bay to see how much I'd have to cut to fit an N52 out of a 330i into the rx7. Call it an impure build but the n52 is not much heavier than a 12A and it produces much more power, much more reliably than a 12A. That's if it'll fit lol)

[@Makjeh]

I have a 525i LCI with an N53, i've never driven one with an N52, but my car has been extremely reliable ever since i bought it in february. Cahnged the oil and filters myself, used Shell Helix 5W-30 and i only fill it up with V-Power. Hasn't missed a beat! Best car i've ever had.

[@xcofcd]

Shell Helix is a good oil but I'd always use a 0W40 or 5W40 and change it every 10-15,000km. To say it very simple the ...W30 oils all have a purposely reduced shear stability by specification. The focus of all these W30 and W20 oils is fuel efficiency over wear protection. Also they have special additives to make the oil "thinner". These additives break over time in the engine and leave sludge behind. That's why you never see an engine that was driven with W30 longlife oil and longlife change intervals that doesn't have brown sludge in the engine.

[@Makjeh]

I've now driven 10,000km with this oil so i'm going to change it very soon anyway, and because the cold winter is coming up (it gets very very cold where i live) i don't really want to go for a thicker oil for the winter, but i might try it next summer, i know that 5w40 works just fine with this engine too.

[@bimmerhuncho908]

You can always supercharge the N52. And if you do tunes right on the ECU, you can have more horses and still be reliable. Superchargers are better than Turbos when it comes to output, hookup options, price (for the parts/replacements & reliability)

My son got an 08 328i with the 6 spd manual for $3,500 about 6 months ago. 180k miles, but Super clean inside and out, black on black with window tint. Great service records (all common failure points done), well maintained, 2 owner car, clean Carfax. He had to jump all over the listing, responded within hours and after we bought it the guy said he had multiple others who wanted it. I think he got a great deal, because I keep an eye on the market as I’m thinking about a 335i with the N54 as a fun car (I daily a 4Runner) and I don’t see anything near that price on E90/N52’s that isn’t beat up. Got an OBD2 scanner w/BMW software that has come in handy. So far have done the battery and starter; transmission and diff fluid changes. Had bolts come loose on the power steering pulley which caused the serpentine belt to rub/tear and proceeded to rip the wiring on the radiator fan, he caught it before it completely shredded the belt though (and potentially avoided the ensuing engine grenading). DIY on all those maintenance/repairs so about $600 (thanks FCP Euro), instead of several thousand $ at a shop. He also put on angel eye headlamp units and blacked out grill and side markers, which makes it look even sharper. Power isn’t crazy but it’s fine for having fun on the backroads. Handles great for spirited driving (compared to domestic/Japanese sedans in that price range). It’s not N54/55 power/fun/modability, but the N52 appears to be a very solid/reliable engine for fun daily driving and not nearly as much maintenance needed as the turbo engines. A lot of car for the money, as long as you’re willing to DIY most maintenance and repairs. Bilstein B8’s and lowering springs might be the next project.

[@edeaton1000]

I was in the market to specifically find and buy a BMW with an N52 but bought a 325i with the N53 by mistake! Its honestly not as bad once the injectors are done, all cars have their weaknesses. Very much like the N52 but with better mpg on a long run. Pros and cons to each but both great engines. N53 maybe a little too complicated for what its worth so I would still prefer an N52.

Hi Dean, I appreciate this channel so much, you’ve taught me a lot, I have an 05 525i - n52b25 on less than 100K, the problem is high oil consumption. No leaks, regularly serviced and maintained. Pretty sure it’s burning it, sooty tailpipe and smoke on heavy throttle. It occasionally throws vanos errors on diagnostics, generally when using the AC and a bit of right foot! Would love to know what you think? Going the get vanos checked ASAP though. Keep up the quality content,

[@ahmedalan720]

Hi there pal I recently got the same car as you and when I first got it it went through oil I then serviced it changed mainly oil and spark plugs to experiment and see if it still burns oil, I used 5-40w oil and only driven 800 miles since .fingers crossed so would recommend that to you got the shell brand 5-40 w from eurocarparts 5-40 oil is thicker then 5-30 so I believe is harder to burn.

amazing engine !!! we have 3 N52 in our house: e90, X1 e84, X5 e70

[@hugobundy787]

They all have the same engine your saying?

Picking up my first E90 330i tomorrow. Can't wait. Last 6 cylinder BMW I had was an E34 525i over 15 years ago.

[@straben2666]

I just bought a 2011 BMW 328i, with the N52, picking her up tomorrow! Ive heard so much good about these cars and these motors, last year for that generation too, (E90 is what i have) and i cannot wait to daily this car, she is a prisitine example, manual, awd and 130k (kms) on it

[@thegladiator1019]

So lucky to have an N52, I baby my car and drive like an old man. The car is spotless. I'm 28.

[@johnbrewer1939]

My experience with N52 is it needs to be driven hard. I used to run at 2500-3000 rpm and had the dreaded clicking sound. Started running this E90 325xi at 3500-4000 and no clicking. Rarely get it into 6th gear on freeway anymore. Runs 26-27mpg at 3500-4000rpm on freeway.

[@EverydayNews4You]

@@johnbrewer1939 yes 👍 these engines like to rev. I usually shift around 4/5l

[@dargo8178]

Love this engine, everyone always says I should move on to a 135i turbo. from my 125i.. I can’t justify it, this engine sings its way to 7000rpm loudly thanks to the NA motor and performance exhaust. One of the best non M engines

[@DankCarzMemes]

Fr got myself a 125i too the engines is great got a remap and an exhaust and it just sounds so nice and its quite fast too i love it. You still got yours? I'll never sell mine

[@AugustDreamScape]

I bought my 08 328i & absolutely love it! Bought it for $3,000 & put a few extra into to. It's the first car to get me into working on & modding a car. About to wrap it after I get the new bumper & side skirt kits. You can make these cars look nice and they are super reliable & fast enough for me. Love it. I'll be modding mine and customizing it more for years to come. It's my dream car essentially. And I'll keep this baby alive forever. The engine is rather user friendly I have found, nice engine bay space for working on whatever you might need or want to work on.

[@elmariachi112]

176k miles on my 325i and the power/reliability the engine has is phenomenal for its age.

[@JT-if4wm]

I couldn’t agree with you more it’s an amazing engine

[@BMWDoctor]

Thanks very much

[@andylead01]

I loved mine Dean!! Until it started to have a rough idle when cold a few days ago 🙁

[@b.b.rodriguez9878]

Could be something simple from a spark plug to vanos solenoid, my e90 is at 170k and running great

[@mrjunior41]

Coil pack

[@mms16mms16]

‘Smooth running values’ test results (with and OBD scanner) takes seconds and can easily tell you if a specific coil/plug is going bad. If plugs/coils/solenoids don’t do it I’d Check for a minor vacuum leak (just put smoke in the oil fill port and see if it escapes). Very small vacuum leaks can cause rough idle on n52 and they are super easy to fix ($10 gaskets usually)

[@felipef6516]

It could be as easy and simple as cleaning the maf sensor.. cheap as chips and fixed the rough idle and stalling on mine. I'd start there, especially if you haven't had it cleaned or replaced before.

[@avigopinath6716]

[@sors1599]

I glad to see this video and why I liked it, I bought a 330xi e90 back in 2013 and I still own it I thought about selling it many times but every time I look at it I fall back in love with it... it’s been stashed away in a garage for the last 6 years I think I want to over haul it and keep driving it, soon it will be a Classic

Oi prices are already going up here in America ladie it’s getting harder to find an E90 with the N52B30 that’s low miles with the 6 speed mad doctor Dean dropping the knowledge once again putting you fools on notice eh keep that info coming Shona cheers

[@johnbrewer1939]

5 years ago a friend had twins, that meant 2nd and 3rd infant seats in the car. Didn’t work in his 2005 325xi 6-speed manual built in Munich and adapted for US. So I bought it off him for $8k with 85k miles on it. It’s at 145k mi today. Love this car, sooooo fun to drive!

Completely agree with the n52 reliability as I own a 1er myself, but curious what makes you say the b58 is unreliable? Basically all reviews/posts/videos ive seen on the b58 praise it for being pretty reliable... 🤔

[@amrmad6446]

I think the #1 reason for the B58 rod bearing issues is running it with 0w20 oil it's too light for the amount of heat & the way ppl drive it.

[@TheFlyingDutchMan8K]

i got one in my Z4 coupe 2006 very happy with it !

[@craigroberts3732]

coming onto 100k miles on my 125i and I love this engine, sorted the waterpump and DISA valves so this thing should run forever

[@peterwilson2588]

Having owned a 330Ci MY2000 from 53000km to 100,000km I found that I was getting MANY issues that should NEVER happen on a properly designed product. Plastics failing on the engine, seals failing, bearings failing, sensors failing, endless issues and this was on a perfect car that had been if anything over-serviced. Beware. There is a reason why you can buy a low mileage EURO car for almost pocket-money. Sure it was a superb car, the best of over 40 I have owned (which included an 8 year old Rolls Royce). But you have to prepared for continual maintenance - OK if you can do it yourself, they are great to work on and parts are very reasonably priced. But if you have to pay a workshop to do this work they are really un-affordable to many people.

[@GerbsInDaBuilding]

It’s fun to work on a motor though

[@philaroo6198]

had a big scare in my n52 yesterday, Just took the ramp onto the motorway and accelerated up to red-line and then Poof Engine stalled, Power steering gone, Hazards and SES light on. pulled over and checked for Smoke or oil and it looked good, Started back up no problems and no strange sounds. Went home and checked INPA, No Codes....!. Been driving it around today pushing red-line and no stalls. Gonna change the oil and check for flakes and do an ignition service as well as change intake filter. Keeping my fingers crossed its not the fuel pump or something internal.

[@samminton3810]

Philaroo Happened to me recently too, although I got CEL showing misfire. For me it was dirty oil after changing the CCVV that clogged the vanos and non return valves. I gave those a clean and put new oil in and now she feels sharp and sprightly again.

[@fastinradfordable]

Oh yeah it sounds so fucking reliable...

[@lilTryhard]

I've had many offers on my 08 128i, but it's just too fun to sell. Glad I decided to keep it

I’m at 212.3K and still daily love the engine only issues I ever had were typical pump, gaskets etc. but as far as engine itself has been the most reliable bmw I’ve owned and I’ve had 6 over the years. 07 E91 Manual Touring ..

How’s it running

[@kevcat8655]

Dr. Dean... Because N43 engine is naturally aspirated, would you say that it is a 'good' engine compared to the modern turbo engines? I know there is a few issues with N43 but would you say it's a good engine?

[@BMWDoctor]

NO N43 is a nightmare engine and very unreliable it runs on the same system as N53 with injector HPFP and NOX SENSOR issues avoid that engine like the plague. for a matter of fact avoid ANY 2.0 ENGINES !!

[@kevcat8655]

@@BMWDoctor Thanks, I currently have one and in the process of DIYing new injectors index 11, spark plugs, coil packs, and timing chain. Haven't has issues with the NOX. Maybe because I do mostly motorway miles at 3k revs, this may help the NOX?

What are your opinions on the N51 SULEV? I'm in the US and my 2008 328xi has just over 160,000 miles and it's still running strong. I've had many people tell me to never get rid of it, however I have heard that these are slightly less reliable than the N52 due to the new SULEV technology added to the E90 in late 2007, early 2008.

[@Kevin-jn7ut]

Does this hold true for the venerable N51 SULEV with the 3 IM?

[@camposjesus3725]

You'd want to go for the N51 always over the n52 just because of the SULEV 15 year/150k mile warranty. BMW covers some very major parts like the fuel pump, valve cover gasket, radiator, thermostat ETC...
