Been loving it on my 330e. EV mode on the city is lovely - smooth, efficient - and get under 8l/100km on the highway cruising at 140kph The only complaint I have with the car was somehow needing new rear wheel bearings before 60k Kms somehow - original brakes, replaced bearings smh...
I have a 2020 230i convertible with the B 48. Mine is the rare M package. No problems with the engine so far. I am concerned with all the plastic connectors and elbows, etc.
I own a f30 330i. Gotta be aware of the plastic oil filter housing cracking(You can get an aftermarket metal one. I paid a shop $1800 to do so before it cracked. Later updated and reinforced in the g20). Also leaky water pump(Think bad gasket but just replaced entirely).
Hi, how is the reliability in a b48 in transversal position? Some of the peripheral devices changes its positioning and the gearbox is different. I.e x1 and x2 have this engine position. Thank you!
I haven’t heard anyone complain about a B48 before or having problems, besides maybe some carbon buildup. I have personally never experienced that tho! I have a friend with the X2 which is a different variant B48 than the 530i and it’s been trouble free.
I got a 2018 G30 530i also with the b46 engine, it's about to hit 100k miles. Keep an eye on your coolant level when you hit 80k miles, I replaced the radiator and most of the coolant hoses due to coolant leaks.
@@vytautaskryzius2556 I have not, the car is completely stock. I do have to say tho, I wish G30 have more aftermarket parts like the F platform, like I noticed a lot of these plastic hoses could be handled in a different way but BMW decided to go with plastic instead of metal. It’s like they’re designed to fail. But overall the car has been pretty reliable besides coolant leakages.
I have problems with my engine, tremors and noises at 130,000 km, vanos stuck error! do you have any idea how to solve it? The actuators are good! What needs to be replaced? Vanos or solenoid?
I have a 2024 with a B48. My main concern with this engine carbon build up. Do you know if BMW has done anything to fix this issue ? Soneone told me the spray pattern on the injectors has been tweaked. The B58 has dual port infection wich prevents carbon build up behind the valves. Wish they woukd have done dual port on the B48.
Hey that’s cool. Hope you’re enjoying the new G60!! I have not had any issues with it but I also drive my car like I stole it in hopes that it doesn’t have time to get carbon build up. Lol!
@lifeonautos8206 it really is a great engine. It's suppose to be very reliable . Have you thought about a catch can ? That should really help. I just can find one for my car 2024 g60 530i... if you decide to put a can. Would be nice to do a video on that.
@ericsivilla4091 great idea! Yes I’ve thought about it but I’m trying to stick to simple power gain mods right now, lol and then will chip away at the other stuff!
@lifeonautos8206 do you know what they have done to this engine to prevent the gdi carbon build up, or do you still have to do walnut blasting every 50k
so, is the fuel conumption around the same for a b58 engine? planning to get a 530i or a 540i but gass in Europe is very expensive just like everything else
I know that if you are looking for top fuel efficiency then the 530i B46/48 is your best bet but if you’re looking for similar fuel economy with more power then the 540i is your best bet. I’m happy with my 530. Unless you plan on tuning your 530i of course which can be easily done (can make it quicker than a stock 540i) with some down pipe, tuning, exhaust, etc..
Yes I am struggeling bro. Deff gonna mod the g30 but idk, if the 540i has little less fuel economy its no brainer for me. But if the 540i is much more thirsty I get the 530i @@lifeonautosofficial
