Hi all--my SES light came on today. I checked the code once I got home, it's p0127 which is IAT (intake air temp) too high.

I have a 2011 e90 335i with 19k miles and INJEN intake. I have had the intake in for a few month now and this code came out of no where. any thoughts? I searched and i do t see a lot about it. This wasn't on the track or anything just driving home from work in SF bay area so.

I am almost sure if I take it to dealership, they will give me shit about the intake.

help appreciated .

Do NOT take a modded car to the dealer for an SES light. There is more than 'shit' they will give you, like flagging your car and voiding all future warranty claims.

I am not sure on this SES light, but it sounds like it would be a typical one if running an aftermarket intake.

very true. Thanks. I would think it is common too but I searched and I don't see a lot of people reporting this, considering the number of people that have intake.

I will see if it goes away on its own in a couple days and if not I'll clear it and see if it comes back. if it comes back it looks like I have to swap to stock and test to see if it comes back

anyone care to help a fellow member out?

Get that piece of shit out from under your hood ASAP and sell it.
Injen intakes are the worst, and are notorious for heat-soak.
Instead, get a BMS intake. Zero heat-soak and a cool whoosh sound too, not to mention dyno proven gains of 7-10 HP at WOT.
Too bad you don't have a JB4 or you could have cleared the codes

really? I always thought Injen made decent products but you are right I have noticed the pipe getting really hot after a drive. plastic is more resilient to heat transfer. I think I might actually do that, plus BMS is soooo easy to swap out in case I need to visit dealer.

injen does go whooosh as well, though.

Anyways, the code cleared itself a couple hours ago. I have a actron scanner but I wanted to wait to see if it went away or I would take it to dealer. I'm really ocd sometimes. how fast is uninstall of jb4?. I was thinking Cobb ap but contemplating the price different and convenience.

I really appreciate your input, man.

What mods do u have and tune.

I've had issues where the maf sensor was seated wrong on the intake and would throw a code.
Pull the maf sensor off and put back on - reseat it. See if that helps.

I ran castless downpipe and the injen intake without a tune for months and it felt solid.
When u start to stack ur powermods, certain mods will not add up with the n55. If u have a tune- cai becomes cosmetic
IMO. Sounds great with the amplified diverter valve going whoosh.

tunes? well let's see.....I have an injen CAI and that's it The SES light cleared on its own today. Idk this whole thing is a mystery and came out of no where... here is something that I am sure has nothing to do with it but at the same time the light came on--my iPod stopped working. Until the next drive.

and yes, the sound is truly amazing. that is why I went with Injen as I don't think BMS would sound the same.

I uninstalled my Injen intake and took the car to the dealership, they said the MAF sensor was faulty and they replaced it. I bought a BMS intake a few days ago and installed it instead of INJEN, much easier to take off before dealership visit but it just doesn't sound as good. :/ oh well.

just an update for future ref.

AGREED. They make great products for certain Japanese cars but for German cars they blow balls.

actually, the BMS is really growing on me. It has a more mainstream sound. but yes, I bought injen at first because of previous experiences on imports.
