Here’s a detailed look at the mechanicals of the BMW 3 series!
The BMW G20 generation features a 2.0L four cylinder engine and 8 speed automatic transmission powering the rear or all wheels. In this video, we take a look at the engine compartment layout, including the engine air intake, lubrication system, ignition system, drive belt, turbocharger and exhaust, cooling system and braking system.
Underneath the car, we take a look at the underbody, engine, transmission, exhaust, differentials, engine mounts, steering and suspension layout. These are taken from the eye of a design, manufacturing as well as ownership layout when it comes to common maintenance items.
Featured in this video is a 2022 BMW 330i with AWD and the 2.0L B48 engine.

I find your videos very educational. I have been a mechanic for most of my life and am just floored by the complexity of these new cars. These cars look cools and are fast but man the repair cost must be outrageous. Thanks for doing these. Keep up the great work.

@aluisious Год назад

Buying a new BMW is foolish. They're made to get good reviews from dumb reviewers who don't consider ownership cost as an important factor. "This is a great car...for someone who isn't going to pay the bills for it."

I’ve had my g20 b48 330i for 3 years now and I have to say that it’s a solid car. Maintenance is easy to. I’ve had no issues since I purchased it. The B48 and B58 (M340i) engines are known to be BMWS most reliable engine since the N54 and N55. I have friends who are BMW technicians and they say that they’ve seen b48’s come in with 75k-100,000 miles on them and no issues at all. I did my oil change a couple months back and it’s very easy to do (DIY) up next on the list is the brake fluid and engine mounts. Everything is going to cost me under $400 to do in the comfort of my home. Despite what people say about reliability, BMW are actually pretty solid cars, IF you keep up with the maintenance. Driver takes care of the car, the car takes care of the driver. Great video 🙏

@marcos223ful Месяц назад

I feel like most cars are reliable now up to 75k miles with unwarranted repairs. Think the problem now is planned obsolescence like water pump and coolant changes (just for example) which in German cars can be complicated with all the electronics and hoses blocking things. But RU-vid mechanic school is worth the shot to save us from labor costs.

@stevesideris8364 Год назад

Timing chain is in the rear of engine. That's why the oil filter is buried back there closer to the oil pump.

@speedkar99 Год назад

Whoa! I missed that one

@--LZ--- Год назад

Seems like bmw figured out nobody does the timing on their engines even when its necessary so they integrated that into their design... they should add a design that catches and recycles all the leaked oil as well. As an e46 owner, newer bmw cars seem like jokes.

@Enthusiastlist Год назад

@@--LZ--- the B58/B48 are miles more reliable than the M54 & S54 found in the E46. I’ve owned an E46 330i and that car was horrendously unreliable & in my opinion the e46 is the generation that gave BMW a bad reputation for reliability.

@--LZ--- Год назад

@@Enthusiastlist honestly if you take care of the engine, its a pretty good one. Sure, the E46 by itself has a lot of issues, and most of these cars are 20 years on the road. Mine is a 330i , its a great project car because mostly everything has been already done and documented online, so i have a lot of guides and material to work with. Plus there's an awesome aftermarket and bmw still stocks a lot of the parts, or remakes them in batches. Just got a 11.1.23 date s54 oil filter housing for an engine oil cooler for example.

@nycupperes Год назад

B48 and B58 are superior engines compared to not just previous BMW engines, but all car manufacturers. The “B” series engines are closed deck designs, and overbuilt on a diesel type block, the 1st generation had the lowest direct inject pressures. The second and third iterations had a single timing belt. I own a 2018 430xi convertible and 2019 740xi and both have been rock solid. Annual maintenance and run perfectly. The biggest issue is the run flats have a terrible ride, so I swap them for Michelin Pilot Sports.

I've been wrenching on the vintage BMWs all my life. One of the things I love about those cars is easy serviceability and parts availability. That thing looks like a nightmare for the backyard mechanic. Not all of us are able to afford the shop rates even for the simple stuff. I can't imagine owning one of these without having a set of backup wheels for when it breaks down, and we all know they will sooner or later

@purplepurplesaurasne Год назад

They're not that difficult at all, there is a few extra steps and everything is torqued to spec, but actually working on late model BMWs isn't that bad at all so long as you know what you're getting into on the parts cost. You know what you are saving in labor which more than makes up for it. My Dad who worked on all the vintage stuff was scared of the computer part, and I keept telling him it is another tool you buy as part of the cost of ownership, and this tool tells you exactly what is wrong and where to start looking. It has been fun helping him with their most recent vehicles.

@nathanpendleton9733 10 месяцев назад

@@purplepurplesaurasneI agree! You hear ignorant people always talking about how complex BMW's are but in reality I find them actually quite easy to work on. I'm of course referring to their inline 6 engines as that's all I've ever worked on! You gotta love the overall simplicity of I6 engines and bmw makes the best ones! Yeah the electric water pump failures and leaky valve cover gasket can be a pain in the ass but compared to doing Audi timing chains it's actually a walk in the park!

They are actually really really easy to work on , I have an E30 , E46 and an F30 with the B48 engine and if you get used to where the pipes go , its pretty simple. I hate the excess use of plastic everywhere though , Those do not last long . no plastic lasts that long . But once you get a hang of these newer cars and newer engines its not bad at all .

This has the B48, a few parts can be tedious, but I would argue that this car is easier to work on than most modern American cars. Also aside from a common coolant line issue and bmw electrical issues breathing down owners necks (nothing common that I know about yet electrical wise), this drive train is incredibly solid. The b48s aren't old enough to say for sure, but on paper it should be incredibly reliable, and the ZF8 transmission is the best torque converter automatic trans you can get.

The 3 series has always been macstrut up front. Base brakes have been basic sliding calipers like those seen here for a long time too. BMWs driving pleasure comes from the suspension tuning and chassis balance. The basic layout of the suspension on this car is the same as the E39 which came out 25 years ago. Always great to see another mechanical review from you! Good stuff even if your BMW hate hurts my fanboy heart haha

@@speedkar99 It is a bit strange indeed. It hasn't stopped them from getting glowing reviews and accolades for the handling and dynamics of their cars though. The suspension system of the front and rear of the E46 is even more rudimentary than post 2006 3 series, and yet it is praised as one of the all time greats. The 911 uses struts in the front too. BMW makes some pretty big profits so I suppose this helps them out.

@chrisbradley3224 Год назад

@@speedkar99 This is the base car, the suspension is a lot nicer on an M3. It's always been a strut, but will have forged aluminum links and better geometry.

Rear steel subframe makes sense - it helps with weight distribution. Regarding brakes: older models had single piston calipers even on performance models. One of the biggest are 60 mm piston calipers for 360 mm dia. and 30 mm thick discs from E90 M3.

Thanks. Isn't an aluminum subframe lighter though? If not, why are higher end cars using it?

@johnnyblue4799 Год назад

@@speedkar99 Well, he said weight distribution not weight reduction. Intuitively it makes sense. If one end of the car is much heavier than the other it will probably affect how it drive, especially in turns. Also, being mostly rear wheel drive it can use some weight placed on the rear wheels.

@pancakewsx Год назад

@@speedkar99 more weight in the rear is actually beneficial here, as it helps to get closer to 50/50 weight distribution. As long as it is not unsprung weight they hit two birds with one stone - save cash and improve rear end behaviour.

@TassieLorenzo Год назад

I suppose, but the Alfa Romeo Giulia is all aluminium in the rear, while Jaguars even use an alunium chassis... If BMW really wanted "perfect weight distribution" (i.e., 40:60), BMW would make more mid-engined cars. For the maker of ultimate driving machines, it is kind of strange that BMW have made so few supercars or exotic sportscars.

These later model BMW are actually quite reliable. So much so that Toyota uses this engine B48 in the 4 cylinder version of the Supra and they use the beastly B58 I6 for the top spec Supra (im aware that Toyota does some tweaking on them but overall its still a BMW). You see engines overall becoming more reliable in order to meet ever so tightening emissions standards. I guess theres one positive to stricter emission. You see this directly with how BMW has gone about retaining heat management. They're able to retain the heat from the engine for something like 36hrs which helps with cold starts as they're one of the hardest on an engine! Overall good video, just FYI this engine does have an intercooler it's in the intake plenum. Would love to see some I6 tear downs!

Toyota does not really use BMW engines and ZF transmissions in their Supra. The Supra is a BMW inside out, and is a fantastic car, in contrary to the older Supra´s, witch only excelled in a straight line after ridiculous tuning. . Earlier Toyota also used diesel engines from BMW.

This is the absolute key for keeping a BMW happy! The people not doing this are where you hear about "BMW'S not being reliable"! These are performance oriented machines thus requiring them to be treated as such. Toyota uses both this engine in the video b48 and b58 in their Supra, so this should go to show that BMW does make very good engines (I4 and I6 engines) you just have to stay up on maintenance for them to last!

Look at recent reliability rankings. BMW is right up there. They know how to build engines and their common i4 and i6 engines are very reliable.

And a 3 series is a great long term purchase. Just service it as required.

I’ve had one for a few months now and the only problem I’ve had is I had to replace the run flat tires since it didn’t ride well with them. Otherwise car is solid. Brakes may be single piston but they brake very well and stopping distance is on par with any of the competition. The struts actually have hydraulic stop dampers inside them which makes the ride more comfortable and controlled. So you get macpherson strut handling plus ride quality, assuming you ditch the run flats… European models apparently option summer tires over the crapflats we get in the US.

Engineers aren't stupid at bmw, and they have a bunch of experience. I think for the requirements they are actually fairly repairable, or as repairable as possible. for example many engines have a top mounted oil filter for ease of access. Their requirements being cheap powerful fun. The unreliablity is from innovation and cost cutting to some degree, not due to absolute stupidity. For example the n54 became the b58 which is good enough for Toyota.

I made the very bad mistake of buy a BMW once, an E90 M3 with the S65 4.0L. I bought it when they were still a current model and the faults which are now well documented were not common knowledge. Mine had the Throttle Body Actuators fail, and the dreaded rod bearings starting making noises, when i replaced them they were heavily worn. Fixed it, sold it, bought an IS-F Lexus which ive had for 7 years, and it hasn't missed a beat.

@chrisbradley3224 Год назад

Yeah but the IS-F engine is meh and the transmission sucks. If you just do the rod bearings and throttle actuators (easy DIY, the actuators that is), you have a much better car to drive. It's a V8 with an 8400 RPM redline, and maintenance is the price you pay for that. You couldn't pay me to drive an IS-F with a crappy automatic vs a DCT or 6MT M3.
