Also is there any mechanical differences between the 20i and the 28i versions of the engine?

Dear all,
I'm actually doing a master in Automotive Engineering and I've a project about this engine (N20B20) in a 328i. I'm working on the oil system, which is really interesting with its variable geometry oil pump. Does anyone has more information about the oil system on this engine ? (Brand of the oil pump, flowrate, pressure, ...) I've already checked the service information manual, but some informations are missing. Also, if you have a CAD model of this engine (or just some oil system parts), let me know. Thanking you in advance for you help. Last edited by G-med911; 11-18-2015 at 05:25 AM.. Reason: Mistake |

I found some decent information on the difference of the N26 compared to the N20 engine, being that more and more engines are now going the the N26 setup for emissions.
I know there is a lot of talk about the N26 HC air filter, and catalytic convertors.

n20
Thanks Jason for the link on the N20 information. I am a former Mercedes Benz Tech . I have worked on some BMW but what I have just experience with a 2013 X3 with this N20 with the timing chain is just as bad as the Mercedes 272 engine failure. The top guide breaks and breaks a piece of the cylinder head off where it is attached and the same at the bottom and damages the block. I swapped out the Engine myself now I got to read this manual and figure out why I get crank and no start:

Great, thank you for this publication. This will be something which will take my attention for a next few nights. On Saturday I will bring 328i F31 and I am little bit nervous, what I will do when some possible problem will show up with this car. Of course I am not expecting nothing, but I saw few posts and discussions here and I am little bit scared.

Engine covers
Hi. I have a 2013 320i. There is an area on the top right of the engine bay which has a lot of exposed wires. Im trying to see if there is a cover available for it. I noticed this jumble of exposed wires last week and i dont like the looks of it. see picture attached.

link for n20 service guide
The link would not open up. Probably user error. Can anyone offer a quick tip? I threw a check engine light on my '16 320i X-drive. Probably from disconnecting a sensor during my tuner install. Had to send the tuner back. Forgot to clear the code. Thanks for any input.
