I have a 2025 X5 with B58. I did a proper break in, varying throttle and not going above 4k rpm and replaced oil and filter at 1,200 with Liqui Moly 0w-20. I won't be running 0w-12, so far running beautifully. I keep it in sport mode and try to avoid start stop. Have 1,683 miles now with the past 400 being heavily 'spirited' driving. Happy engine so far. Imo, BMW's 10K interval is likely the culprit. At 1,200 my break in oil and filter were quite dirty. Can't imagine not breaking in properly and then pushing the original 0w-12 oil 8,000+ miles. There's your problem.

The G42 M240i is the C8 Corvette of BMW. It's their "Last Hoorah" as SavageGeese put it. Contrary to popular belief you don't have to buy an M3 Comp for rwd/awd toggle. I have been pouring hundreds of hours of time into reverse engineering and w/out xDelete support, I'm able to take mine to drift events no problem (I have videos posted). I'm working on a 0s-and-1s-level deep dive into every control module and it's job in maximizing traction or sideways stability. And it JUST SO happens to be the fastest, quickest BMW. Ever. It doesn't have 48v either. The Gen 2 is so so goddamn good. I'm not surprised in the least that the G42 hasn't gotten the B58TU2 yet. But after this iteration, the 7 series and EVs have FULLY locked down ECUs with Secure Coding 2.0. After the B58TU(1) - you won't be able to do almost anything fun to the cars.

I'm no fan of cylinder deactivation technology. GM has been having issues with this for years. On the later LS and LT engines. By about 70K-75K the deactivation lifters tend to either rotate in their bores or get stuck. If the lifter rotates, that respective cam lobe tends to get wiped out. And turning it off via the software does nothing. The deactivation system must be removed and standard lifters, etc. must be swapped in. I knew someone who had this happen and went with a fresh cam, removal of the deactivation plenum and standard lifters installed. No more issues. Sometimes, more complex tech isn't always the answer. Just because one can do it, doesn't always mean one should.

[@user-yq6ov6ow7l]

I am seemingly the only person that saw this video. But before the supra was released there was an interview in japan with lead engineer from toyota where they went over the b58. The original b58 was designed by bmw and then brought to toyota. Toyota completely dissected it, stressed tested every single little piece, and brought it up to their reliability standards. Bmw learned a lot from toyota and how extreme they are about reliability. This process happened prior to the release of the b58 in 2016. The video was on KZbin around 2018 then suddenly disappeared. My point being is that the further the modified by bmw, the further you get from the engine that toyota helped design. I don’t know if toyota had any input in the gen 2 b58, but I’m going to guess they did since it was installed into a supra.

[@Villani_AV]

If i remember correctly toyota stress tested everything and the b58 met or exceeded their test requirements, not that they developed it with bmw. The b58s reliability over the n55 came from a closed deck and completely forged rotating assembly, plus a new system to reduce wear on start ups

Cylinder deactivation hardware kit is a pipe dream. With drivetrain hybridization on one hand and on the other-complexity of on board computer modules/data bus protocols, the likelihood of such modification for new BMW cars has never been lower. It’s crazy but seems more likely that the manufacturer would eventually offer such deactivation through the dealer network, as opposed to aftermarket modification and endless reprogramming attempts to make all systems (including vanos) talk to each other without triggering fault codes and other mayhem. If there is a small chance, it will be explored by a couple of very high-end shops in the eastern block countries which specialize in heavy modifications of newer bmws. One such shop says they don’t expect to be able to reliably do this in the foreseeable future. Maybe in a couple of years they’ll figure something out, but even then, it won’t be as straightforward as GM’s AFM/DFM delete.

Be it 0w-12 or 0w-30. None of these weights have any effects (as to thickness) on an engine at normal operating temperature. My understanding as to using thinner oils; is to break in a new engine for the first 5,000 mile or recommended oil change. After that everyone I knew would go to 5W-30 and abandon 0w-30 for the very reasons your stating now. In 1994 the 3 cylinder Chevrolet turbo Sprint had similar issue and It recommend oil was 5w30; which is way to thin for that size of engine.

Cylinder deactivation technology sounds all good and true when it comes to application & theory. But in long-term reality, it's a ticking time bomb. Honda's V6s for instance w/the CDT, eventually the engine have problems from unequal temps between cylinders which causes problems - the solution is to have Honda tech deactivate the programming feature - only catch is that your gas mileage goes down in return for realiability.

Have you seen any issues running thicker oil (LL01 / 3.5 HTHS such as M1 0W-40 or PP Euro) in B58 Gen 2 or B48 Gen 2? I’d think not since it’s marked acceptable in TIS.

[@masturone8257]

So to help the environment they have to implement changes on a properly operating motor that require motors to be opened and closed due to issues. Doesn't that require more oil changes? More trips to the dealer wasting fuel? More tows using less fuel efficient vehicles to pull heavy weight? More stress on the electrical grid since dealer has to make more service appt, tickets, etc? More parts being manufactured to replace issue parts? More development on older tech instead of next gen? Etc? Or is the mindset that if the car sits with issues then it's not driven and won't burn fuel, but then it only work if no rentals had to be given out and mostly vehicles with older tech are rented?

[@dennyo661]

Any issues with belt tensioner and alternator making noises? Mine is 2022 M340I X drive. Dealer changed tensioner out twice and it still makes noises.

This gen1 2 3 and TU model numbers are new to me.. I’m wondering which version of b58 engine my 2021 F22 M240i has 🤔

How do you know what gen you have? What years are gen 3?

[@blazesmooth5573]

april of 2024 is the start of gen 3 b58s

[@spoiler9112]

​@@blazesmooth5573 Not accurate. My M40i was built in May 2024, and it's a Gen 2.

[@andrewmeier5854]

Basically the 2025 models are gen 3 from my understanding. The new X3 (the one that looks way different from old model) has that one for example.

[@yg78t76t7]

Auto Start stop was very bad for starters. What’s the point of saving 10 cents in gas when you have to buy a $1200 starter later on? Now they wanna do the same with the cylinders? Gas is cheap, rebuilding the motor is not. They should just push this for the electrics not ICE cars…

[@myemailiscool]

Can you provide examples of starters going bad directly due to stop start? it's been around for over a decade, i haven't heard of this. Engineers consider these things.

[@Orzeszekk]

Only in America. In Europe gas is expensive and we don't have our own reserves. BMW is European company. 1200 euro spent on starter is money which goes to pocket of European mechanic and circulates in European economy 1200 euro spent on gas is fueling Russian reigme or arab kings

Bro. I think the best thing you can do is look for the engine model on your car and find the corresponding numbers online. Your VIN number might have the model number or the engine itself should have a sticker someone with the exact model. I don't have a B58 myself so unfortunately I cannot tell you exactly where it is, but my 2009 Merc has it, so I'm sure your car should too.
