Default odd code Audi A8 E4/D3

Hi Folks.
I am driving a 2005 A8 4.2Q with about 118kmiles on it. Had some work done recently to fix a valve cover gasket and replace a cam chain tensioner.
Also replaced a MAF based on dealer advice.
I have a code : 16490 Manifold / Barometric Pressure Sensor (G71) / (F96) P0160 - 008 - Implausible Signal - Intermittent -MIL ON Readiness 01101100
Car runs fine, smooth idle, no problems really other than a MIL which will be an issue for emissions.
Now here is the problem. I can't find this sensor on my car. There is no clear hit on the internet either. I was given a part number 03C 907 386 E which is for a sensor but still, not sure where it would go and if it is actually meant for my car. Do I actually have one?
Any help would be appreciated.
Adil

This part number comes up as the intake runner position sensor. See if this item looks familiar.

Default nice pdf

Found this nice pdf for our engine which indicates on p.36 that the F96 altitude sensor in part of the ECU. http://www.kpematop.com/S6/V8-5VEngine.pdf

Now that takes care of the barometric pressure sensor part of the code. I will explore this more in the scope of resetting/adapting the J220 module. Any direction will be appreciated.
Now for the MAP sensor G71, I have not been able to find it yet. Still looking for help locating it.
Also I keep thinking that replacing the MAF sensor a few weeks back may be related. I read somewhere that barometric/MAP and MAF readings are compared, therefore the 'implausible signal' could be caused by any of them being off, so, I will check that area for anything I may have missed. Hoses, clamps, etc...
