P1419 Fault Code 2004 X5 3.0

[rotorwng1]

I have a 2004 X5 3.0i
My OBDII reader says I have a P1419 fault code. None of the local Import shops can tell me what is wrong with my X5. I have replaced the Mass Air Flow Sensor. 400 Bucks with no avail. Has anyone else seen this code with this Piece of SHIT BMW? If so, please help me fix it so I can sell it as soon as possible. Thanks for your help.

Hmm, P1419 doesn't seem to show up anywhere as a valid OBD-II code. Do you have any driveability problems, or is it just that the CEL is on? You might want to try a different code reader - Peake Research's tool works very well with BMW's. Did any of the import shops try reading the code out themselves, or were they just going by the P1419 code you gave them. Why did you change the MAF - did you have reason to suspect a problem with it in particular? You definitely don't want to be throwing expensive parts like this at it, hoping for the best :-)

I agree that you need to have the codes read out by someone with a mainstream diag system (DIS, GT-1, Solus, etc). Your code reader may be confused.

I FIGURED IT OUT! I finally took my car to the dealer after going to two import mechanic shops. The first shop also read the P1419, secondary air flow circuit malfuction. This is why I replaced the MAF sensor.. they told me too.. PS: I'll be contacting that company and asking them to send me 400 wasted dollars.
The second shop got the same code and they didn't have a clue!
Third, I went to the BMW dealer.. DUHHHHH They found out that secondary air really is secondary air. This sensor measures the ambient air temp and decides weahter or not I need air forced into the manifold at start up. This can looking device is mounted opposite the MAF sensor in the engine compartment and can be replaced for under $100.
Thanks for the comments.

Hello rotorwng1,
my x5 is seeing this P1419 problem, what is the name of the sensor the measures the ambient air temp at starrtup. many thanks!

Wow.. a year later I read this. Sorry it took so long. I guess if anyone else is living with this problem then you will need to order part number 11-72-1-438-814.

It's called the Secondary mass air sensor. Don't confuse this with the Mass Air Flow sensor which costs 400.00. The part you need can bet acquited online around 68.00.

PEACE!

If it matters Code P1419 on a aftermarket code reader is Secondary Mass Air Flow Sensor and the previous post is correct buy a BMW # 11.72.1.438.814 in Canada its 169.00 but it will correct the problem

My 2005 x5 3.0i just popped up with the same problem. I'll look for that part and see if it fixes the problem.

I have a 2005 BMW X5 3.0L, my Check engine light came on and I took the car to a shop to read the code, the code is P1419 secondery Air flow sensor, BECARFULL not the main air flow sensor which is $500plus. By reading a few post from this site I tried the secondary sensor and solved the problem.
The sensor OE # 11-72-1-438-814 $180 cnd. Thanks.

FYI - for those who ever need to replace the larger MAF for the actual engine intake, you can get them also in the $70-$100 range by either using Range Rover MAF's (same motor for a while) or using a certain VW MAF (search www.m5board.com since I don't remember the #). Just throwin it out there to save people some $.

Can anyone tell me how to locate the secondary air flow sensor in an X5 3.0 engine?

Can i just clean the connection

Definitely try cleaning the sensor with MAF cleaner first. Here's a DIY:

hello
I have the same problem code p1419.
I change already the second mass air sensor(try to clean the old one first, no luck), clean the connections, clean the valve as well and the "check engine soon" is still there.
I did check the valve by blowing air and it its going a little bit out( I read that is how should be) I do not know what the problem can be, I will check the pump tomorrow morning
I am thinking did I need to reset something i mean disconnect the battery or reset the computer some how so i can clear the check engine light
thanks a lot
