Anyone pull out the extra air filter on the N26? - BMW 3-Series Forum (F30 / F32)

NNJF30 · 10-09-2012, 10:43 AM

I tried running an aftermarket intake but kept getting lean faults. I went back to stock but I removed the extra air filter they added for the N26. The lean fault returns but it takes much longer than with the aftermarket intake installed. I also have a BMS stage 1 tune and am hoping that isn't what's causing the fault.

Simple enough to determine. Put the extra air filter back it and wait for the lean fault. If you don't get the fault, suspect the tune.

I know, I'm just sick of messing with the damn thing lol. I took it in and out a few times already trying different things to get the aftermarket intake to work

I'm sure you checked, but vacuum line is nice and tight?

Yeah I triple checked it. Have you had a chance to dyno before/after with the tune and downpipe yet? Still rocking out with the SES light? lol

tiltmode43 · 10-09-2012, 04:26 PM

Yup, still have the light on, lol

Haven't dyno'd yet - I probably won't do one without the dp, a bit too hard to switch out on a whim. Will do with & w/o tune though. There's a dyno in the shop next door to ours, I should have gotten numbers through every step of the modding process, kind of regret it now.

Do you have a photo of it? How do I know if I have an N20 or N26?

N26 has an electronic wastegate. Easiest way to tell

L0UD0G · 10-20-2012, 04:55 PM

Wouldn't it also say SULEV or ULEV underneath the hood? I have a 2012 328 in Arizona with the N26 manufactured in 5/2012 and mine says SULEV underneath the hood and I have the electronic wastegate.
So if it says SULEV then its the N26 and if it says ULEV then its the N20 right?

john_f30 · 12-09-2012, 12:01 PM

my 2013 328i has an electronic wastegate and its a N20..

john_f30 · 12-09-2012, 12:04 PM

to check which engine you have is to look for the stamped engine code at the front of the cylinder block.. its between the air intake box and the block.

Interesting, I was under the impression all newer F30 328i's in CA, as well as some other states, were N26? I thought I had read all manual transmission cars would be N20 but this could have been incorrect.

On your title is your car listed as 328i or 328is? I believe N26 are listed as 328is which indicates SULEV (Super Ultra-Low Emissions Vehicle).

It's listed as 328i

My 2013 328i 6MT has an N20, and an electronic wastegate. The 2013 BMW ordering guide published last June indicates that there is no SULEV/N26 with 6MT, only ULEV/N20. Of course that's subject to change at some point.

clarence · 01-06-2013, 08:26 AM

The electric wastegate was fitted to N20 since 7/12.
