Best year for B58?
I'm looking to pick up a 340i but would also consider a M240i or 440i.
Is there a year to stay away from? EX: Is the 2017 + 340i better then the 2016?

I purchased a 2016 model brand new and have clocked 95,000 miles on it. Not heavily modded, but I do have Dinan springs/sways, bootmod3 stage 1, and xHP.
One rear diff seal formed a small leak, so I replaced both seals. Other than that, nothing unexpected has cropped up.

If you are considering tuning then there is a cutoff point around june 2020 where BMW locked the DME. I don't have the exact details on my mind but if tuning is a thing look into this.
If you are considering 2016 vs 2017 is may be wise to look at the builtin cellular device and make sure it uses 4G instead of 3G. 3G cellular support is most likely terminated so in that case your car falls back to 2G which severely limits the online options of the car. |

Also, 2016 did come with the ID4 interface and a lower spec NBT EVO HU.
If you want ID5/6 (which gives you CarPlay) and do not want to swap your HU, then look for a 2017+ model.

There was a pretty important revision to the vanos system in August of 2017. The cams, sprockets, and valves were all changed due to issues in the early version. The injector part was also changed right around then. The early 2016 models or more prone to the injector failures, as mine was. The oil pressure sensor was reduced from M12 to M10, right around then as well. I don't know why I imagine due to the Vanos changes. The TU and Gen 2 changes are pretty well documented. But there are a few sneaky changes throughout just gen 1. If there are any more I will probably find them soon.

All good info.
I think my take away is to try to grab a 2018-2019, but not count out the earlier models. Thanks everyone

But I would worry about body style / packages and color combinations on your B58. |

I’m looking into purchasing my first bmw, I am currently looking at a 2020 440i and I am planning on modding it, but I don’t see anywhere about piggy back tunes such bm3 or mhd on it, is it possible for me to tune it or no?

How is any of this related to the B58 engine which both the subforum and the thread are all about!?

No it is fine. We can also talk about the best year for Brunello wine to go in the trunk of the car… since it is also related, but actually the question was specifically about B58… and so is this part of the forum.
Excuse my sarcasm just wanted to keep the thread tidy, before people start talking about the difference in suspension and Harman Kardon between the model years….

The JB4 is a piggyback option. I personally use BM3 and wouldn't choose anything else for the mere fact that I can create my own tunes, but that's not for everyone. You basically have two camps on the flash side of things, BM3, and MHD. MHD seems just as capable, it was just a personal choice for me not to use it. As for JB4, I don't really see anyone talk about it too much (I still don't know why this board doesn't have a dedicated Engine Management forum, but I digress). The JB4 however is a piece of hardware, would not require the Femto unlock to use since it's microcontroller basically just interrupts the voltages from the engine's sensors, scales them, and spits them back out so the DME gets "tricked" into thinking engine conditions are one way when they are another. It doesn't make an actualy changes to the DME. Plus it can be removed when selling the car without any software licensing issues. |
