Intake air temperature sensor
I think I found the part online so it should be not too difficult to find. I thought it was calculated from the MAF but now leaning toward a separate part.

All the part diagrams I have seen give it as a separate part and as you say is quite easy and a cheap job. But I am finding it hard to track the exact position for my model. Maybe somebody out there is familiar. I did see one diagram where the sensor was pointing up under the intake manifold. There are diy videos on other models where it is pointing down. In mean time will keep researching. Thanks Andrew for your comment.

Ok so that wasn't easy to find. I found quicky for the M54 right in the center of the intake manifold.
The N62 it seems as suspected incorporates the IAT into the MAF. Makes for a pricy fix for a temp sensor that should be $40. There is a kit to relocate the IAT to a better spot that conveniently splits the job of the IAT and MAF which cold save a pretty penny if the IAT died but the MAF is working http://bd8ba3c866c8cbc330ab-7b26c6f3...stallation.pdf

I can observe this same effect on my 3.0d when scanning it when the engine is hot (after a run). Just sayin

Thanks wpoll and everyone for comments. I had the dreaded failsafe program come up this moring. Its not nice to have this happen in peak traffic. I think it might be too coincidental with the error message perhaps. I have had the 4x4 warning come up before but neather with the failsafe program (image below). I got to work with my fingers crossed and when I get home I will put the obd2 on it again.

I don't think the 51 is the problem. The computer is reporting not plausible. Not shown is the snapshot of the value that brought out that error.

Ok, jumped back in the car to head home and no warning lights. I think this may be the start to end for the MAF. I notice some others have had the failsafe and MAF issue.
https://xoutpost.com/bmw-sav-forums/...af-sensor.html So, another item needed to order. Interesting though, with all the warning lights you can still drive on reduced function. |
