I have only heard about leaking issues from the B48 and B58 Engines. But for others here is a list also with part prices in USA 1. Plastic coolant tank pipe can leak (30 USD) -> Is known to crack and leak even before 60k miles check that one out 2. Plastic Oil filter housing on the side can leak (issue with cracking plastic) (300 USD) 3. The Water Pump can leak coolant and fail (tbh almost any German vehicle has problems with failing water pumps at some point of time) (176 USD) 4. The plastic coolant flange on the side of the engine can eventually leak coolant too (2 Reasons either it cracked or the O ring gone bad) (19 USD) 5. If you realize none is leaking and you have disappearing coolant level then check the cap of the coolant tank, that one can be faulty and leak air. (22 USD) 6. Of course Valve Cover Gasket. But this of course will fail according to how much heat you give it via driving hard. Still this is a wear item and it will eventually fail. (55 USD) So if you have 600-800 USD on hand with tools and you trust yourself in repairs, an used 330i or any 30i Engined BMW since 2015 can be a good purchase if the price is good and all the conditions above are already repaired or met upon. I can say though, a friend of mine drives his 530i xDrive very hard with 0W30 Oil every 6-7k miles and it still didn't have any issues with the aforementioned issues.
I own a 2017 330i xDrvie with 70k miles. So far I have had a leaking water pump, Oil FIlter housing cracked(Replaced with an aftermarket metal one) and, just had my Fuel pump go out on me.
4:03 is where the title becomes relevant. And it's not really that relevant, as others have noted, because BMW has recalled the small amount of B48 engines that have this defect, at least so far. And I've never seen one actually have this issue. Don't buy into this. Not yet, anyway
So far the B48 seems to be one of the most reliable engines BMW has ever made. But of course it can have issues, like any other engine. Nothing is perfect.
Really! not a chance the N series are junk motors the most reliable engines BMW made are the M-10 M-20 M-30 M-42 series of engines where the best bulletproof BMW ever made.
The amount of plastic is a serious issue. Aside from pumping in 10s of thousands in repairs to my N55, the plastic deterioration is becoming unmanageable. The engine needs major components replaced at just 9 years old. The car is worthless on the secondary market. The word is out.
@@FFE-js2zp Wow 10's of thousands of $$ in just replacement cooling system parts on your E-90 N-55 powered 335 i?. The N55 is one of the best of the N series engines BMW has produced in the last 10 years. Are the cheep recycled plastic components are they gold plated for that kind of money lol?. BMW should be ashamed for making junk plastic disposable vehicles that fall apart past the warranty there riding on peoples ignorance and the past glory days of the 60's to 90's era cars.
@@bmw540iable At last count my 2011 135i, price $47K, has $60,000 in repairs. That includes the old sheared VANOS bolts migrating to the oil pan requiring a 2 week engine rebuild, the starter started electrical fire burning out every single electrical component in the car, and the typical $2K, oh, every other month or so. It needs a new top, as the shit fabric has disintegrated with dozens of slits, the AC has given up the ghost, the rear main seal is gushing oil, the oil pan gasket is leaking from at least 5 places, requiring disassembly of the tacked-on X straps and dropping the front subframe, and the 6MT pops out of 3rd. The pleather seats are both ripped and thr entire dash is delaminating. I could sink another $30-40K in repairs into it, but its only worth $2K on a great day, so no. Shittiest car on earth, worst ever, absolute turd engineering.
This is an isolated problem with a very small number of B48 engines. I have a 2018 420i with the B48, 180,000km. Changing my oil every 15,000km. It overheated once at around 50,000km, I paid 350$ to replace a gasket. That's literally it. A very reliable, smooth engine. Still idles as quietly as it did when I bought the car.
I have a 2017 330i with a b48 45k miles. Upgraded my intake pipe, charge pipe, catless downpipe, and went BM3 stage 1. I drive like a menace often and have owned the vehicle for a year and a half of course I get my usual maintenance done. Only issue is I blew a coolant pipe and my car overheated about two weeks ago. I'm under warranty and BMW fixed it for free in a day even with all the mods, they also did my brake pads while it was there, I was blown. Today my car drives better then when I first got it. I'm happy. Next I think I'm doing coilovers.
@@aarongrisham5555 ty I see to many of these videos where people tune their car before upgrading their charge pipe or upgrading their intakes but not the full intake pipe, it kills me on the inside
@Jason also, those were issues with N20. I know where you pulled the source. It also says, these are suspected but none have been reported. Came out 7 years ago. Bye kiddo
B 48 IS ONE OF THE MOST RELIABLE ENGINE IF YOU DON'T KNOW, WE HAVE WORKED WITH FLEET COMPANY AND WE HAVE 788 VEHICLE IN OUR FLEET ALL OF THEM WITH B48 ENGINE AND ITS G31 and G30 models. All of them cross 486000 KM easily..
This is the first time that i have heard of this issue in the UK, and there are literally thousands of these engines on the roads here, both in BMW's and the Mini's
Im a Technician at BMW, honestly based of my multiple years experience when Bmw vehicles have issues its because of the owner. Not maintaining it properly plain and simple.
Not exactly true, my brand new 430i has weird issues like random loud banging when braking in the reverse gear or engine being randomly loud for a long few seconds after a start. Contrary to the test drive car, the gearbox doesn't shift quickly, while sometimes even doesn't lock the hydraulic clutch, the issue is with decision time, I press the throttle and it takes a second or two to reduce a gear even in sport mode. It has just wound 2000km on the odometer and I have not revved it over 3k RPM, I have actually treated it with the ultimate care. Not to mention 2020 models lacking rear floor mats. That's a bummer.
I disagree. BMW, much like other manufacturers started quoting ridiculous lengthy service intervals (20,000 miles) only as selling points. Sadly, these lengthy service intervals were and are arguably the cause for many of these catastrophic engine failures such as chains snapping etc. So, I do agree with your point regarding maintenance, but it is BMW's fault for falsely guiding people on maintenance, which they did to increase sales. The second reason behind many of these engine failures is poor quality and engineering. This of course does NOT apply to all engines BMW has or is making, but there are a handful of engines BMW made that are simply poor.
I agree my mechanic told me the same thing. The owners lease them and have them washed and detailed so the outside looks pretty, but when it comes to maintenance he says they want to put in oil that's not recommended for the car and they want to use cheap parts for maintenance. He said once the lease is up and they trade it back in it's a ticking time bomb for the next owner who buys it unfortunately. He told me if you get a BMW either get a newer model and also make sure you get an extended warranty to cover all the expensive and necessary repairs you will eventually have to deal with at some point.
@@aa7h911 I totally agree what moron said it's ok to change your oil every 10k miles is an idiot. Common sense will tell you the viscosity of the oil will break down fast especially in today's turbocharged vehicles.
It’s a BMW . If it’s not design too be drove aggressively . Why call it an ultimate driving machine. Perhaps ultimate failing machine. My F30 LCI B48 went service center more than I visit my grandmom.
The B46/B48 is more than just more reliably than the N20, its smoother, more refined, and generally just better. Its closed deck, the lifter and injector noise is all but gone, and the new balance shaft has made it almost as refined as the B58. Thats on top of fixing the oiling and timing issues of the N20. I've still not seen any real reason the B48 won't be a very solid engine in the long run. The counterbalance shaft recall ended up affecting a handful of G-series cars, and that was that. None of the early F-series B46 and B48 engines got recalled.

All other systems will show the stop sale starting tomorrow. SITUATION BMW of North America, LLC is conducting a Voluntary Safety Recall (effective October 9, 2019) on a small number of Model Year 2019 and 2020 BMW vehicles that were produced between November 19, 2018 and August 26, 2019. The counterbalance shafts may not have been produced to supplier specifications. This could lead to severe engine damage and engine shut-down. The engine will need to be replaced. Approximately 217 vehicles are affected by this recall.
I have the B48 in my JCW GP and its solid so far. I drive the car like a demon... 7500 miles so far no issues... thinking it would easily go to 200k with maintenance. The B48 in the GP has these improvements: reinforced crankshaft with larger main bearings and new pistons with a lower 9.5:1 compression ratio to allow more boost with the larger turbo. Cooling on the GP is solid as well, 3 radiators!
@@grownupgaming Only 217 cars is really no big deal. I'm actually glad BMW got on top of this for those owners. Seems like BMW is actually trying to up their reliability game now
Thanks, Good to know about the potential counter balance shaft bearings coming loose. I am at 63K miles on an X3 30 so I am in that zone where selling may be a good option.
Mark, is the same issue occurring in the B58? I called my BMW mechanic in december to chat about the B48. He says besides some minor cooling issues, he hasnt seen any problems but hasnt seen any past 180km in his shop. This engine is about 7 years old now.
You have two different type B48 engine codes in the 320, 330, 330e - B48B20A and a B48B20B engine code do we know if its both engine codes or one or the other. The B48B20B is the more tuneable version. B48B20B on a stage 1 tune is around 400bhp and 460+lbft, whereas the B48B20A is only 340bhp and 400lbft with Xtraboost function and stage 1 tune.
There was a recall campaign in 2019 for replacing some engines with the faulty balance shaft bearing. So I guess this should not be a problem anymore, at least not to the extent of having a catastrophic failure with low mileage.
Got a 330e, so hopefully i will delay issues by driving on the electric power 😅 I love the performance and the feel of the BMW. You have to forgive it for some issues, but it is good to be aware
I have a 2021 330E 13000 km so far. No issues. Check engine light briefly came on, said it was a software issue. Updated. And said there was no mechanical problems
It seems there is a lot of difference between the B48A and B48D. The old B48A(B48B20***) seems to have much less issue than the new ones (B48B20***). Can you be more specific about the problem and sub-models to which these issues relate? Thanks.
My most reliable BMW was a 2000 E46 325i with a 5 speed manual , that thing ran like a champ with just regular maintenance up until I sold it at 210 thousands miles , I also owned an E39 540i with a manual , an E90 323i and now I own an E60 535xi also manual ,
I love manuals as well, had the 2010 335 xi and LOVED IT. Only car I owned that I put 100k miles on. I strayed from 2017 to now because I was so pissed that the manuals were taken away.. but after driving an Audi s3 that also didn’t have manual. I went back to Bmw.. I’m still pissed that they took the manual away though.. it would make me a thousand times more passionate about my car:(
My 2017 330i is about to hit 100,000 miles and so far it's still running great. No recalls, though there was a service advisory released last year (2022) about replacing the top coolant line and so I'll probably do that eventually whether it breaks or not. Other than that I plan on keeping my car for at least another 10 years and I'm even thinking about getting a second 330i so my twin turbo has a twin. 🙂
Nice the twin scroll single turbo b48 is a solid power plant and between those and the b58, those are the best BMW engines right now. S58 is still sitting with the jury
@@ECPP Yep the B48 paired with the Z4 transmission forms a solid performance combo. The main thing is just running a good maintenance schedule and for me that will include replacing the coolant line when I flush the system around 100k anyway. Thanks for sharing your knowledge and expertise
This is a very clickbait title. So far this issue is only affecting 2019/2020 models, and *only* 240 of them. That doesn't mean ALL B48 engines will have this issue. More info below: "BMW is recalling about 240 model year 2019-2020 BMW 330i, 330i xDrive and 2019 BMW Z4 vehicles because the needle roller bearings of the counterbalance shafts may have been improperly installed, a problem that can cause the counterbalance shafts to loosen. According to BMW, a loose counterbalance shaft can cause severe engine damage. About 217 recalled vehicles are in the U.S. and 23 are recalled in Canada. The automaker says the U.S. recall will begin December 6, 2019, when dealerships will replace the engines."
Yes, that has the most reliable engine in the BMW fleet, the B58. So far they are showing to be fairly sturdy and it’s the same engine as In the Toyota Supra. With that said, if history repeats, just be ready for lofty shop rates, pricey parts, and possibly the odd cooling system woe and ocassional oil leak. Great for a few years anyway.
I have a 2019 330i right now with 86k miles and the only issue that occurred was Thermostate went out at 34k miles. Other than that no issues other than replacing the rims from potholes cuz of the run flat tires not as durable.
the problem only catches engine produced between 2018 till August 26 2019. and they are not all of them,for example only 214 cars are recalled that they have problem in USA and they sold thousands of them.
True. That problem have only G series 2018+. The 2018 models have upgraded (with big problem lol) version of b48 engine, also in eu have this upgraded version partikel filter for petrol engines.
True, I read this in some past bulletin, however, they have affected on G20's and new 5 series on 2019 models only, mainly North America with a few hundred. It's understood that 2020 onwards models are trouble free.
a quick summary video like this one on the name codes of all the "bad" engines and which cars have it is good imo, ik u already done this a lot but adding it up would be really appreciated am sure by new and used buyers
I enjoy watching your videos I find them informative however I would like to know your motivation for bringing this issue up now? From all reports BMW recalled the affected cars and repaired them as it wasn't a wide spread issue with the B48.
imagine someone goes " bmw is not reliable ..i spend a lot for fixing ..maybe time for a toyota" then go buy new toyota supra.. 😂😂 addition : supra 2.0 use b48 and 3.0 use b58 for context..
@@ECPP ok, thought so. I was looking at a 2014 328i m-sport a while back , and I asked a tech at my job (a BMW dealership actually, lol) and he said it was a ticking time bomb. I did my research a saw that the post 1/16 engines had a revised timing chain, but I ended up with a GTI instead. I'd live to get a car with the B48 or B58 in the next few years. Keep up w the great videos, man!
17 B46/48 125k water pump or coolant module, numerous tank vent valves, valve cover because PCV system clogged, plugs coils, also hear that the oil filter housing can crack and leak coolant into the crankcase diluting your oil and potentially killing your engine. Have done transmission service, front and rear differentials and transfer case.
Hi Mark, I love your channel! I have been wanting to buy a b48 330i for a long time just like many others. One of my biggest goals will also be not getting hit by big repair bills as I will be running on budget. It would be great if you could make a video for us where you talk about the things we should change before they fail to make the engine more relable.
@@ZRazzleDazzle I agree best advice is buy a clean car a one or two owner car that has never been hit with a clean title. Also make sure they have service and maintenance records to back up there claim as well.
@@bballah9969 Definitely! I am planning to go with a Certified Pre Owned with no more than 30K miles. if I could somehow know the usual failure points at 50K, 100K etc. I can take care of those things early before they fail. That will be the best.
Mark, Have a 2019 540i, picking up next week a 2007 650i with only 27k miles for 25k U.S. I think N62 engine. Replacing valve seals, water pump and every other issue noted with this engine before I pick it up, which is why I am paying 25k for it. What is your thoughts and experience with this engine?

@@beny.5872 my wife stole it from me. Quiet and nice ride. Just got back from trip driving 1500 miles. I am a leadfoot, but still got 29 mpg on the trip. Real feel like the 6 turbo engine is plenty of power for this car. 550 not necessary unless you a re a maniac about 0 to 60 times. The 540 is the perfect blend of power and economy in my opinion. Hopefully that helps.
Intressting that nobody talk about coolent disappearing, i have a b48 2018 and it has no leak and still drinks after almost one year of driving, i have talked about that problem with my bmw dealer and a answer i got is if you run you car hard it will drink so i dont know if this is normal for a car to drink water even if you dont press it hard on the street. Do somebody have the same issue with the 320i b48? And is it normal for any car to drink water? And need to be filled up?
This is a known issue for the b48 and b58 engines but generally coolant consumption comes in one of 2 ways. It either drinks it or leaks it and finding the source of this can be very difficult. Many people see this to some degree in these engines but there is an answer and it should not consume more or less based on level of spirited driving.
Hi! New subscriber from Chicago. You’re videos are awesome! I’m looking to purchase a used 2 series. 2017-up. Maybe a 228i xdrive. Are they reliable? TIA.
Hi Hubert, thanks for watching and welcome to the channel. The engine in the car you describe is the b48 turbo4 and it has shown to be quite solid so far and other than a few recalled for a bad intermediate shaft bearing which was poorly installed. BMW is always a little more likely to fail than say a Lexus, but they are wonderful to drive so this may be a solid trade off.
Up here in Montreal, Quebec, we would see the 1 series on the side of the road waiting to be towed. Especially in winter. One day a few years ago, my 2012 Infiniti G37xS Coupe had a blown serpentine belt during warranty and needed to be towed to the dealer. While in the cab with the tow truck operator I asked him which car they saw the most often and he told me the 1 series BMW, Mercedes SUVs and the Audi A4, A5 with the 4 Cylinder engine.
Hi James, with that said it is one of the most reliable current BMW engines alongside the b58. Also with that said, I would like to see what these engines are like behind the 100,000 mile mark. Time will tell.
I have an issue with it here in Australia. 2016 BMW 330i M Sport. Engine light is on and off. Vanos error when checking but now a new error has shown up. BMW states timing chain sounds fine. Euro specialist where I live is advising timing chain. Body shakes and low rev hesitation. Noises in the cabin like a rattle. And fuel consumption is up. Car is not in warranty but has always been BMW serviced and really the issues should have been picked up I have been quoted $5500 to fix it.
When you hear about BMW engines, it feels like they are self-sabotaging their own brand and sales! How long a car company can be around with a reliability like this?
@@jbcarsvids4128 thanks. I’m in Mexico and here came with the B48 engine from Germany. I have confirmed it in the workshop report after recent service at the dealer.
What a load of toss. This engine has existed for years at Mini and is known as being vastly more reliable than the N26/20. Yes the initial B46D (TU) did have some issues up in a few months of 2019 when G20 production was ramping but that’s it really. Trust me, I had one of those early cars and they had a lot of issues but it was almost entirely supplier related to the GXX models specifically. I have heard only good things from others about the engine and trans specifically…the rest of the car is up for debate.
b48's in f55/f56 Mini's first year or so were plagued with some engine bearing issue. They replaced the engine in my F56 2014 Cooper S at only 6k miles after it took a crap and the I noted the recall campaign. Now at 80k and the only issues were the notorious engine mounts (piss poor design) going bad, and now the tranny mount as well.
Here's another reliability issue with B48 - poorly design coolant vent line that break/leak over time specially in hot climate area. There's a recall from BMW US - BMW Service Information Bulletin: SIB 17 01 21. For those live outside US, may be worth get it done as a preventive maintenance anyway.
I prefer the 2000s decade when it comes to BMWs. The N52 naturally aspirated 3 liter straight six is bulletproof but, skimp on oil changes you will be sorry. N52s still have plastic valve covers and intake manifolds but, have metal oil pans and all metal oil cooler. There is nothing wrong with plastic oil pans if it’s designed properly though. Some parts such as the oil cooler are not meant to be made out of plastic unless it’s PEEK which is cost prohibitive or be used in an EV drivetrain or for the transmission fluid instead of the oil in an engine.
Because of this N52 I was about to hate BMW :) ...I will not enter in details ( I want to forget my experience) - in short just check how many updates they did for Cylinder heads ! As far as I remembered around 5 ?! Any way NO to N52 !
You know that the B48 is a modular engine right? So the B38 3 cylinder and B58 6 cylinder would all have the same issues. Everyone across the world with actual mechanical knowledge has said these generation of engines are vastly improved and the issues of the N motors banished.
The 3 cylinder and 6 cylinder will have different balance shaft arrangements due to different vibration characteristics, in fact the 6 cylinder probably doesn't have one at all.
Yes it refers to the production method and the fact they share the same bore and stroke, as well as a few design characteristics. What did you think it meant?
@@simonh870 the original comment explains it all. I have a b48 engine and never had any problems at all. The only problem i had was oil leak bc someone installed a bad oil filter during the oil change
Well not everyone would have an issue, the internet tends to distort the truth. But the 3 cylinder, 4 cylinder and 6 cylinder versions are still massively different in many ways. They just have to be. For example the 4 cylinder has a balance shaft, the 6 cylinder doesn't. The 3 cylinder has an eccentric flywheel to counter the front to rear rocking motion which is a charicteristic of that type of engine. The 4 cylinder isn't just a sawn off 6 cylinder..
B48 is a 4 Cylinder B58 is a 6 Cylinder developed with Toyota that's in the Supra. 240, 340, 540 and 740 have the engine. Best engines from them right now. Most reliable
Its small problems like these that give bmw a bad name. Just like any other engine out there have its problems. The only difference is that Mark always hightlights the faults of BMW engines. Mark you should send BMW a list of problems experience so they can fix it. Can you make a video of the problems they fixed in the 2.0lt N46 and well as the 2 different versions of the B58. Earlier versions as well how it compares to TU version
Im pretty sure it's big problems like your engine blowing up from rod bearing failure is what gives BMW a bad name. not to mention no oil dipstick. I actually had the electronic oil level meter fail and the car would keep reading empty even though it was just filled.
I have the N46B20 engine and I want to upgrade, I am looking at the B48 right now, even the B38. The N46B20 is a decent engine, it's not a smooth engine, sounds like a diesel and if you don't put new original dampeners it vibrates a lot.
For about 5 months I had a 2017 911 S4. In that time, with less than 30K miles, it went through a water pump, left side muffler assembly, clutch pedal assembly, fuel tank sensor, all of which would have cost over $9K if it wasn't for the warranty. However, it drove!
Nonsense. Why did I have to watch 4 mins of this video before I found out what the issue was???? An issue presented from just your word of mouth...no links or references...just heresay. Disliked.
It is a legit issue, but it didn’t affect more than 200-300 cars built in 2018 and 2019. And they were all recalled and fixed. So this is not a common problem at all.
I have only heard about leaking issues from the B48 and B58 Engines. But for others here is a list also with part prices in USA
1. Plastic coolant tank pipe can leak (30 USD) -> Is known to crack and leak even before 60k miles check that one out
2. Plastic Oil filter housing on the side can leak (issue with cracking plastic) (300 USD)
3. The Water Pump can leak coolant and fail (tbh almost any German vehicle has problems with failing water pumps at some point of time) (176 USD)
4. The plastic coolant flange on the side of the engine can eventually leak coolant too (2 Reasons either it cracked or the O ring gone bad) (19 USD)
5. If you realize none is leaking and you have disappearing coolant level then check the cap of the coolant tank, that one can be faulty and leak air. (22 USD)
6. Of course Valve Cover Gasket. But this of course will fail according to how much heat you give it via driving hard. Still this is a wear item and it will eventually fail. (55 USD)
So if you have 600-800 USD on hand with tools and you trust yourself in repairs, an used 330i or any 30i Engined BMW since 2015 can be a good purchase if the price is good and all the conditions above are already repaired or met upon.
I can say though, a friend of mine drives his 530i xDrive very hard with 0W30 Oil every 6-7k miles and it still didn't have any issues with the aforementioned issues.
if you want to know uncommon issues that can still appear, just write
Thanks

So far the B48 seems to be one of the most reliable engines BMW has ever made. But of course it can have issues, like any other engine. Nothing is perfect.

I have a 2017 330i with a b48 45k miles. Upgraded my intake pipe, charge pipe, catless downpipe, and went BM3 stage 1. I drive like a menace often and have owned the vehicle for a year and a half of course I get my usual maintenance done. Only issue is I blew a coolant pipe and my car overheated about two weeks ago. I'm under warranty and BMW fixed it for free in a day even with all the mods, they also did my brake pads while it was there, I was blown. Today my car drives better then when I first got it. I'm happy. Next I think I'm doing coilovers.
@@prevaloir5362 very smart. I would always suggest upgrading ALL intake and coolant lines. THATS where BMW FALLS SHORT
@@aarongrisham5555 ty I see to many of these videos where people tune their car before upgrading their charge pipe or upgrading their intakes but not the full intake pipe, it kills me on the inside
@Jason also, those were issues with N20. I know where you pulled the source. It also says, these are suspected but none have been reported. Came out 7 years ago. Bye kiddo
B 48 IS ONE OF THE MOST RELIABLE ENGINE IF YOU DON'T KNOW, WE HAVE WORKED WITH FLEET COMPANY AND WE HAVE 788 VEHICLE IN OUR FLEET ALL OF THEM WITH B48 ENGINE AND ITS G31 and G30 models. All of them cross 486000 KM easily..
This is the first time that i have heard of this issue in the UK, and there are literally thousands of these engines on the roads here, both in BMW's and the Mini's
Different manufacturing plants maybe?
Im a Technician at BMW, honestly based of my multiple years experience when Bmw vehicles have issues its because of the owner. Not maintaining it properly plain and simple.
Not exactly true, my brand new 430i has weird issues like random loud banging when braking in the reverse gear or engine being randomly loud for a long few seconds after a start. Contrary to the test drive car, the gearbox doesn't shift quickly, while sometimes even doesn't lock the hydraulic clutch, the issue is with decision time, I press the throttle and it takes a second or two to reduce a gear even in sport mode. It has just wound 2000km on the odometer and I have not revved it over 3k RPM, I have actually treated it with the ultimate care. Not to mention 2020 models lacking rear floor mats. That's a bummer.
I disagree. BMW, much like other manufacturers started quoting ridiculous lengthy service intervals (20,000 miles) only as selling points. Sadly, these lengthy service intervals were and are arguably the cause for many of these catastrophic engine failures such as chains snapping etc. So, I do agree with your point regarding maintenance, but it is BMW's fault for falsely guiding people on maintenance, which they did to increase sales. The second reason behind many of these engine failures is poor quality and engineering. This of course does NOT apply to all engines BMW has or is making, but there are a handful of engines BMW made that are simply poor.
I agree my mechanic told me the same thing. The owners lease them and have them washed and detailed so the outside looks pretty, but when it comes to maintenance he says they want to put in oil that's not recommended for the car and they want to use cheap parts for maintenance. He said once the lease is up and they trade it back in it's a ticking time bomb for the next owner who buys it unfortunately. He told me if you get a BMW either get a newer model and also make sure you get an extended warranty to cover all the expensive and necessary repairs you will eventually have to deal with at some point.

I totally agree what moron said it's ok to change your oil every 10k miles is an idiot. Common sense will tell you the viscosity of the oil will break down fast especially in today's turbocharged vehicles.
It’s a BMW . If it’s not design too be drove aggressively . Why call it an ultimate driving machine. Perhaps ultimate failing machine. My F30 LCI B48 went service center more than I visit my grandmom.
The B46/B48 is more than just more reliably than the N20, its smoother, more refined, and generally just better. Its closed deck, the lifter and injector noise is all but gone, and the new balance shaft has made it almost as refined as the B58. Thats on top of fixing the oiling and timing issues of the N20. I've still not seen any real reason the B48 won't be a very solid engine in the long run. The counterbalance shaft recall ended up affecting a handful of G-series cars, and that was that. None of the early F-series B46 and B48 engines got recalled.

SITUATION
BMW of North America, LLC is conducting a Voluntary Safety Recall (effective October 9, 2019) on a
small number of Model Year 2019 and 2020 BMW vehicles that were produced between November
19, 2018 and August 26, 2019. The counterbalance shafts may not have been produced to supplier
specifications. This could lead to severe engine damage and engine shut-down. The engine will need
to be replaced.
Approximately 217 vehicles are affected by this recall.
totally agree Henry!
I have the B48 in my JCW GP and its solid so far. I drive the car like a demon... 7500 miles so far no issues... thinking it would easily go to 200k with maintenance. The B48 in the GP has these improvements: reinforced crankshaft with larger main bearings and new pistons with a lower 9.5:1 compression ratio to allow more boost with the larger turbo. Cooling on the GP is solid as well, 3 radiators!
@@grownupgaming Only 217 cars is really no big deal. I'm actually glad BMW got on top of this for those owners. Seems like BMW is actually trying to up their reliability game now
Do you know if i can find de B48 in a F30 2017?
Thanks, Good to know about the potential counter balance shaft bearings coming loose. I am at 63K miles on an X3 30 so I am in that zone where selling may be a good option.
Mark, is the same issue occurring in the B58? I called my BMW mechanic in december to chat about the B48. He says besides some minor cooling issues, he hasnt seen any problems but hasnt seen any past 180km in his shop. This engine is about 7 years old now.
You have two different type B48 engine codes in the 320, 330, 330e - B48B20A and a B48B20B engine code do we know if its both engine codes or one or the other. The B48B20B is the more tuneable version. B48B20B on a stage 1 tune is around 400bhp and 460+lbft, whereas the B48B20A is only 340bhp and 400lbft with Xtraboost function and stage 1 tune.
There was a recall campaign in 2019 for replacing some engines with the faulty balance shaft bearing. So I guess this should not be a problem anymore, at least not to the extent of having a catastrophic failure with low mileage.
Hopefully most have been addressed already
@@ECPP 217 I believe...
Agreed..
kid, have you ever bought a BMW before?
the B48 and B58 are top notch improvements all around including reliability over the older BMW crap.
Got a 330e, so hopefully i will delay issues by driving on the electric power 😅
I love the performance and the feel of the BMW. You have to forgive it for some issues, but it is good to be aware

@@hammy316 Lexus isn't slow lmao and they're reliable enough to not worry about these on a daily basis and horror stories.
I'm wondering if bearing issue is present in newest 2021 BMW 430i ????
It seems there is a lot of difference between the B48A and B48D. The old B48A(B48B20***) seems to have much less issue than the new ones (B48B20***). Can you be more specific about the problem and sub-models to which these issues relate? Thanks.
You bet I will be doing a video on that coming up
Yup, I did hear right, Mark just invented the BMW 238i. Good info, hopefully BMW takes care of this issue through a recall.
Lol, you caught my slip of the tongue. Cheers
I believe the body style from 2007 2013 are the same basically. Did any of these cars come with 4-cylinder engines that are reliable?
Well…….
My most reliable BMW was a 2000 E46 325i with a 5 speed manual , that thing ran like a champ with just regular maintenance up until I sold it at 210 thousands miles , I also owned an E39 540i with a manual , an E90 323i and now I own an E60 535xi also manual ,
My old man has a 2001 E46 330i.
His one has pretty much never let him down. Just keeps on chooching
I love manuals as well, had the 2010 335 xi and LOVED IT. Only car I owned that I put 100k miles on. I strayed from 2017 to now because I was so pissed that the manuals were taken away.. but after driving an Audi s3 that also didn’t have manual. I went back to Bmw.. I’m still pissed that they took the manual away though.. it would make me a thousand times more passionate about my car:(
Just got a 2020 330i xdrive and I’m so nervous about something breaking. Even though I’m a technician at a dealership. 😂
Dam!!! Thank you for the information!!! Maybe that’s why I still drive my 2000 323i @ 240k miles!! lol Stay blessed brother!!!

@@dylanorr2127 I love those straight 6’s!!!!
My 2017 330i is about to hit 100,000 miles and so far it's still running great. No recalls, though there was a service advisory released last year (2022) about replacing the top coolant line and so I'll probably do that eventually whether it breaks or not. Other than that I plan on keeping my car for at least another 10 years and I'm even thinking about getting a second 330i so my twin turbo has a twin. 🙂
Nice the twin scroll single turbo b48 is a solid power plant and between those and the b58, those are the best BMW engines right now. S58 is still sitting with the jury
@@ECPP Yep the B48 paired with the Z4 transmission forms a solid performance combo. The main thing is just running a good maintenance schedule and for me that will include replacing the coolant line when I flush the system around 100k anyway. Thanks for sharing your knowledge and expertise
4 minutes before you get down to the issue. Counter balance shaft bearing coming loose for anyone who wants to save their time.
Does this issue also affect the b48 in the 2024 g60 5 series ?
This is a very clickbait title. So far this issue is only affecting 2019/2020 models, and *only* 240 of them. That doesn't mean ALL B48 engines will have this issue. More info below:
"BMW is recalling about 240 model year 2019-2020 BMW 330i, 330i xDrive and 2019 BMW Z4 vehicles because the needle roller bearings of the counterbalance shafts may have been improperly installed, a problem that can cause the counterbalance shafts to loosen.
According to BMW, a loose counterbalance shaft can cause severe engine damage.
About 217 recalled vehicles are in the U.S. and 23 are recalled in Canada.
The automaker says the U.S. recall will begin December 6, 2019, when dealerships will replace the engines."
Thanks for sharing
Does this mean a 2016 430i will be more reliable?
Any comments on 2018 740i Sedan 4D engine and reliability ?
Yes, that has the most reliable engine in the BMW fleet, the B58. So far they are showing to be fairly sturdy and it’s the same engine as In the Toyota Supra. With that said, if history repeats, just be ready for lofty shop rates, pricey parts, and possibly the odd cooling system woe and ocassional oil leak. Great for a few years anyway.
@@ECPP thanks for your input 👍
Always been toyita guy finally got the b48 bmw. Been missing out on how fun these cars are
I have a 2019 330i right now with 86k miles and the only issue that occurred was Thermostate went out at 34k miles. Other than that no issues other than replacing the rims from potholes cuz of the run flat tires not as durable.
the problem only catches engine produced between 2018 till August 26 2019. and they are not all of them,for example only 214 cars are recalled that they have problem in USA and they sold thousands of them.
True. That problem have only G series 2018+. The 2018 models have upgraded (with big problem lol) version of b48 engine, also in eu have this upgraded version partikel filter for petrol engines.

I enjoy watching your videos I find them informative however I would like to know your motivation for bringing this issue up now? From all reports BMW recalled the affected cars and repaired them as it wasn't a wide spread issue with the B48.
What about N26 say something about it please I’m currently driving one 328I xdrive
I think the engine internals of the N26 are
exactly the same as the N20, with the only major differences related to fuel delivery and exhaust.

Hopefully that helps.
Intressting that nobody talk about coolent disappearing, i have a b48 2018 and it has no leak and still drinks after almost one year of driving, i have talked about that problem with my bmw dealer and a answer i got is if you run you car hard it will drink so i dont know if this is normal for a car to drink water even if you dont press it hard on the street. Do somebody have the same issue with the 320i b48? And is it normal for any car to drink water? And need to be filled up?
This is a known issue for the b48 and b58 engines but generally coolant consumption comes in one of 2 ways. It either drinks it or leaks it and finding the source of this can be very difficult. Many people see this to some degree in these engines but there is an answer and it should not consume more or less based on level of spirited driving.
been having to top off my coolant as well. coolant light came on the first time it got so low . i drive a 2017 330i

Hi! New subscriber from Chicago. You’re videos are awesome! I’m looking to purchase a used 2 series. 2017-up. Maybe a 228i xdrive. Are they reliable? TIA.
Hi Hubert, thanks for watching and welcome to the channel. The engine in the car you describe is the b48 turbo4 and it has shown to be quite solid so far and other than a few recalled for a bad intermediate shaft bearing which was poorly installed. BMW is always a little more likely to fail than say a Lexus, but they are wonderful to drive so this may be a solid trade off.

One day a few years ago, my 2012 Infiniti G37xS Coupe had a blown serpentine belt during warranty and needed to be towed to the dealer. While in the cab with the tow truck operator I asked him which car they saw the most often and he told me the 1 series BMW, Mercedes SUVs and the Audi A4, A5 with the 4 Cylinder engine.

What a load of toss. This engine has existed for years at Mini and is known as being vastly more reliable than the N26/20.
Yes the initial B46D (TU) did have some issues up in a few months of 2019 when G20 production was ramping but that’s it really. Trust me, I had one of those early cars and they had a lot of issues but it was almost entirely supplier related to the GXX models specifically. I have heard only good things from others about the engine and trans specifically…the rest of the car is up for debate.
b48's in f55/f56 Mini's first year or so were plagued with some engine bearing issue. They replaced the engine in my F56 2014 Cooper S at only 6k miles after it took a crap and the I noted the recall campaign. Now at 80k and the only issues were the notorious engine mounts (piss poor design) going bad, and now the tranny mount as well.

No just remove German car company from your driveway and it will be reliable
What about the 2018 bmw m550i is it reliable I’m just getting into bmws
I prefer the 2000s decade when it comes to BMWs. The N52 naturally aspirated 3 liter straight six is bulletproof but, skimp on oil changes you will be sorry. N52s still have plastic valve covers and intake manifolds but, have metal oil pans and all metal oil cooler. There is nothing wrong with plastic oil pans if it’s designed properly though. Some parts such as the oil cooler are not meant to be made out of plastic unless it’s PEEK which is cost prohibitive or be used in an EV drivetrain or for the transmission fluid instead of the oil in an engine.
Because of this N52 I was about to hate BMW :) ...I will not enter in details ( I want to forget my experience) - in short just check how many updates they did for Cylinder heads ! As far as I remembered around 5 ?! Any way NO to N52 !
X5 30? Where? I haven’t seen that.
You know that the B48 is a modular engine right? So the B38 3 cylinder and B58 6 cylinder would all have the same issues. Everyone across the world with actual mechanical knowledge has said these generation of engines are vastly improved and the issues of the N motors banished.
The 3 cylinder and 6 cylinder will have different balance shaft arrangements due to different vibration characteristics, in fact the 6 cylinder probably doesn't have one at all.
@@simonh870 do you know what modular engine means 🤔🤔
Yes it refers to the production method and the fact they share the same bore and stroke, as well as a few design characteristics. What did you think it meant?
@@simonh870 the original comment explains it all. I have a b48 engine and never had any problems at all. The only problem i had was oil leak bc someone installed a bad oil filter during the oil change
Well not everyone would have an issue, the internet tends to distort the truth. But the 3 cylinder, 4 cylinder and 6 cylinder versions are still massively different in many ways. They just have to be. For example the 4 cylinder has a balance shaft, the 6 cylinder doesn't. The 3 cylinder has an eccentric flywheel to counter the front to rear rocking motion which is a charicteristic of that type of engine. The 4 cylinder isn't just a sawn off 6 cylinder..
Is this the same engine found in the 2 liter supra?
B48 is a 4 Cylinder
B58 is a 6 Cylinder developed with Toyota that's in the Supra.
240, 340, 540 and 740 have the engine.
Best engines from them right now. Most reliable
@@samuraiska320 the b48 is also in the Toyota Supra as wel
@@samuraiska320 2L supra is a B48, 3L supra is the B58.
do a video on the c class
Cheers
Its small problems like these that give bmw a bad name. Just like any other engine out there have its problems. The only difference is that Mark always hightlights the faults of BMW engines. Mark you should send BMW a list of problems experience so they can fix it. Can you make a video of the problems they fixed in the 2.0lt N46 and well as the 2 different versions of the B58. Earlier versions as well how it compares to TU version
Im pretty sure it's big problems like your engine blowing up from rod bearing failure is what gives BMW a bad name.
not to mention no oil dipstick.
I actually had the electronic oil level meter fail and the car would keep reading empty even though it was just filled.
I have the N46B20 engine and I want to upgrade, I am looking at the B48 right now, even the B38. The N46B20 is a decent engine, it's not a smooth engine, sounds like a diesel and if you don't put new original dampeners it vibrates a lot.

BUY PORCHE!
nice video mate
Thanks a lot much appreciated.
For about 5 months I had a 2017 911 S4. In that time, with less than 30K miles, it went through a water pump, left side muffler assembly, clutch pedal assembly, fuel tank sensor, all of which would have cost over $9K if it wasn't for the warranty.
However, it drove!

Thankfully I didn't, it was a family members car that he gave to me to drive.

mark do u recommend any shops in the Edmonton area for BMW issues and maintenance?
Nonsense. Why did I have to watch 4 mins of this video before I found out what the issue was???? An issue presented from just your word of mouth...no links or references...just heresay. Disliked.
It is a legit issue, but it didn’t affect more than 200-300 cars built in 2018 and 2019. And they were all recalled and fixed. So this is not a common problem at all.
2021 M550 ? Y/N ?
please advise.
