na the intake air temperature sensor. not sure whether you guys have a different name for it.

i think the only plug that plugs on the back of the intake box is the Auxiliary Thermostat Sensor...

Intake Air Temp(IAT) sensor is located on the intake manifold. You'll find the connector on the underside.

Did you solve the issue? i'm also having same problem, you probably bought the one of the performance wanna be chip from ebay just like me

more than likely . the advert for it has a glossy black lowered 5 series i think.i gave up in end. the bmw dealer looked at me as if i was talking in some strange foreign language when i asked him to locate it for me. think i'll just drive it as it is. thanks for replying.

for your year & model, the IAT is located on the underside of the intake manifold, right by the throttle body.

Since it is upside down it is hard to pull out. Something is catching it on the dge. How do you remove it? Is it supposed to be loose? I'd like to put some sealant to make it tight and seal it from vacuum leak.

It's under the intake manifold somewher nea the center near the throttle body. You'll have to remove the throttle body since it is in the way. Once removed you can see it thru the intake manifod round hole. It is upside down. Unplug it by pushing in the spring wire lock while pulling the plug down with the other hand. I'm trying to remove it right now but couldn't pull it out. Even if I twist while pull ing it down it won't come out. Something is catching it on the edge. I don't want to force and break it. I just want to remove it and put some sealant to keep it tight and prevent vacuum leak. Need some help here. Thank you.
