F48 new B48 engine

image Here the new B48 engine in a new X1 front wheel drive and also 4×4,,,,,I know interesting,,,,I finally got to work on one and drive one and check it out,,,had to perform its first oil service.image Here the location of the oil filter under the car,,,,you can see there is a small drain plug at the bottom of the filter,,,,the new factory and yes I said factory oil filter came with the drain plug for the oil filter,,,,,I know the aftermarket filter will not come with one,,,,changing the oil filter is not a easy thing,,,,,not enough room to get a socket on,,,,you need a short 32 mm socket,,,,if not the subframe gets in the way.image Here something interesting,,,I was resetting the oil service and noticed you can only reset the oil service, vehicle check ,and brake flush,,,,you can not reset or see the front and rear brakes,,,,,the brakes are old school E46 only when the brake sensor starts to touch will it indicate brakes are due,,,,,,ok driving this car and new engine,,,,power was ok for this car,,,it shifted good through the gears,,,,it felt like a front wheel drive car but also you can feel the 4×4,,,,headroom and interior space was ok,,,,you can sit 4 male adults in this car no problem,,,also the gear shifter was old school,,,you actually have to move it into the next shift gate.,,,I enjoyed driving the car,,,,will see how this new engine goes in the future.

    Hi, Thanks for the info!
    I’m planning to do a service on my F30 330i with the same engine, and would like to know the socket size for the drain nut at the bottom of the car. Do you know the socket size required?
    Thanks in advance

    Hi, will the B48 have the same intake valve carbon-buildup issue common to all DI engines? My wife wants to buy the X1, and I’m wary of what I saw with BMW’s first DI engines– most need walnut blasting at about 60K. Did BMW do anything different with the intake on the B48 to prevent this problem?
    Thanks– Tim


    • Oh good question,,,,I went to school for that engine,,,,and I remember asking that same question,,,,the teacher had no answer for me on that,,,,all he said is that it is to early to tell,,,,I would like to think we still might have the same problem due to there is no fuel washing down the intake valves on a direct injection motor,,,,I know other car makers are having the same problem.,,,Honda and Mercedes to name a few.

    Hi what is your thoughts on the transmission fluid? for BMW x1 the f48 body If we should replace it or keep it. Bmw says its life time but alot of forums say fluid should be replaced. IF we do replace it BMW says the fluid they use cost like 1000 dollars. if you do recommend to change it what fluid do you recomend


    • I recommend the BMW fluid,,,,ouch 1000 that hurts,,,,BMW idea of a life time 100k miles of the life of the transmission which ever come first,,,,sometimes replacing the trans fluid on a high mileage car can cause more problems.

    I guess I’ll add my 2 cents here as I am an ICML certified Machinery Lubricant Analyst. Being a mechanical engineer that has worked in mining for more than 20 years I’ve done a fair bit of lubricant training and review on all kinds of equipment. Generally speaking, we don’t bother with light vehicle analysis because they’re low cost but the ideas are the same. There is no such thing as a lifetime lubricant period. Good lubricants are the lifeblood of operating machinery. For my F10 550i I was out of warranty at low mileage because it’s a manual and I want to keep it for a very long time so it is rarely driven. At 40k miles I sucked out and replaced the rear diff fluid and drained and refilled the manual trans. I didn’t bother to send them off for analysis but I saw nothing to indicate issues. The engine gets changed 5-6k miles instead of the now reduced from 15k to 10k interval. Additionally, I use a 0W40 Mobil 1 oil as it has a higher zinc content to help protect the turbos but not so high as to cause catalytic converter problems. The factory grades are too light in my opinion as they’re more about achieving fleet mileage than doing what is best for the engine. I just dop Blackstone samples on the engine oil and it has always been good. I recently bought a x1 28i x drive m sport as a daily so that will get a host of fluids somewhere between 35-4ok. As the tech stated, you won’t harm anything else by changing fluids but in an auto trans you can cause problems if it has been left too long as a lot of crud can become stuck to the inside of the torque converter and when you put in fresh fluid it has detergents that can loosen old deposits which can then cause issues by clogging the valve bodies. I’ve always been a manual man but these days you don’t really have a choice and they offer the benefit of more gearing options. The filters are now often part of the pan and very pricy so the best bet might be to drive it and if you know you plan to keep very long term then do it probably before 60k at least. Again, my 2 cents so they’re worth what you paid.

    Hi BMW Tech. Thanks for the fantastic Blog you keep. I have a 2019 320i F30 with the B48 engine and ZF 8 speed with idrive 6. Now. I have an opportunity to move to a G20 320i and I have heard that the G20 has the same engine and gearbox. Is this true? Besides idrive6 and look of car, do you feel the G20 is that much of a different vehicle to my F30 in terms of engine, gearbox and suspension? Is it worth moving to the G20 at this situation? Thanks again for the work you do.
