Sep 27, 2021 · B48/46 is not basically the same engine. It couldn’t be more different than the N20. The only thing they have in common is that they are both 2L turbos. That’s about it. There is basically nothing that’s carried over from N20 and the first time BMW has put out a …

Feb 10, 2023 · For the 2ers, it's clear that the B48 engine was introduced in late 2017 (July iirc) with the LCi models, but for the 3 Series I cannot find any clear information on this topic. I would like to get the B48 because I saw it's easily upgradeable via an ECU flash or a piggyback to over 300hp, so I'd love a 320i or a 328i 2.0 4cyl.

Jul 10, 2024 · Many guys analyze that BMW cars coolant leaks because of BMW’s high coolant temperatures.The high coolant temperatures can lead to a higher pressure in the pipelines， as high as 1.4 bar, causing the plastic parts to age and eventually leading to coolant leaks.

Nov 3, 2024 · No, that one is on the N54/N55 and is easy to replace on the front of the engine. This is on the 4 cyl B48 (2017 430i) so is under the intake manifold and has 3 bolts. Cracked down the side from the heat. BMW should have made it aluminum! I’d post a picture but this forum won’t let me submit new pics.

Some of the most significant changes compared to N20 include: B48 uses a closed deck block, rather than the open deck design of N20; Revised balance shaft design; Revised CAC design; Revised Valvetronic mechanism; Mechanical main water pump with a supplemental electric water pump for the turbo

Jan 15, 2021 · HI, I have a 2017 BMW 330i, which apparently has a coolant leak from the oil filter housing gasket. I believe that my car has the same engine (B48). How much you paid for the repair? $3000 seems to be way too expensive for this repair. In addition, if anyone have information about this issue, such as doing a DYI repair, please share. Thanks in ...

May 24, 2020 · Almost everyone who has a car with B48 engine, uses RON98 gas. According to European manual, recommended RON is 95, acceptable - RON91, but no any words about a higher octane. I took rental cars twice in US, at West Coast, and the highest octane I saw on gas stations during my journeys there - was AKI91.

Nov 3, 2021 · Yes, BMW should have done a recall for this problem. Instead, I bet 100’s if not thousands of owners have to pay out of pocket. I know I read a thread from a European forum where some owners took signatures from other owners for BMW to take responsibility and have a recall. I don’t know how that ended. The software update should fix your ...
