THROTTLE BODY ISSUE, CODE P0068, FIXED
I got in my car this error codes:
012410 - Air Intake System: Flow too Low
P307A - 009 - Open or Short to Ground
000104 - MAP/MAF <-> Throttle Position Correlation
P0068 - 007 - Short to Ground - MIL ON
Could not find too much information related so i will explain how my codes were gone.
-I removed the throggle body from the car(air filter hose removed and 4 screws that hold TB to the rest of engine)
-I sprayed(i used TB & air intake cleaner from MOC)all mecanism and cleaned up with a regular cloth.(i didnt put spray even close to electronic module).
-after clean the mecanism ,i opened the electronic module(6 metalic holder that i just pull out with a flat srewdriver)and cleaned with dry cloth also bend the slower brushes slightly so they make proper contact.
After put back the TB on the car ,,I erase my dtc codes and make an Throttle Body Adjustment using ross-tech specifications....:
Throttle Body Alignment (TBA) - Ross-Tech Wiki)
After 2 days the codes never come back and now my car it is a lot more smooth ( i think MPG is a little higher too),i will do this procedure every 60 k or 70 K miles because my TB was dirty (i been doing aire filter change on time and i use only shell premiun gas for the last 3 years or so)and after cleaned up my car move better.
Excuse any gramatical mistake, I'm learning English... hope this helps someone...

I had a repair shop that was getting this DTC, would clear, test drive for a day and the fault always returned. I had them clean the throttle body and do an adaption and they reported back that the fault has not returned since then. I added that to the Ross Tech Wiki:

I had a similiar code for MAF. It was intermittent though. So i did the exact same thing you did and now the codes are gone

had the same problem and the above steps fixed it thanks.
One important step is missing: take out the snow screen from the air intake and clean film of the dirt from it. I think this step alone can fix the problem in many cars with hight miles. I measured the airflow before and after the screen was cleaned. it improved by 20%.
Here are some pics for the throttle body steps.
1. you need to take off rear engine plastic cover and disconect vacuum hose from air intake pipe. It is connected via impossible Audi clips so I replaced it with the metal band with tightening screw from Autozone for the next time.

disconnect other wires and fuel line so you can get the air pipe out. Mine has chafed flange. I think the air leak or polluted air created this MIL problem. Needless to say, I am very impressed with the quality of service of whoever jammed the pipe in first place. Probably audi technician when he replaced the air filter.

now unscrew for bolts as marked and take off the throttler.

the rest is very well explained in the original post.

I was thinking about doing this also. What drivability issues were you having besides the trouble code? Did you happen to have unstable rpm's at light throttle?
I am having an rpm oscillation at very light throttle and all of my tests so far seem to be pointing to the throttle body.

I did not notice any other problems from your list. But I would recommend to do it because the procedure is pretty straightforward with good ROI.

Hey all, I'm a newbie here....have lurked a bit in the past. I have a 2006 A6 C6. I am just getting the P0068- code which is a MAP/MAF improper correlation.
Should I definitely take out the throttle body or is there any way to possibly clean it without taking it out. I don't have one, but am thinking of purchasing a VAG-COM. If I don't take it out, I won't have to recalibrate it, right? I was thinking of trying to clean it out and then clearing the codes with a friend's code reader and seeing if the P0068 light comes back. As it is, the check engine light is not always on.... Any thoughts? Also, if I have a few more beers, I may just order a VAG-COM tonight.

If it does not work out, you can proceed with taking off the throttle body. But this is not a biggy as well. I think the worst part was disconnecting electric connectors.
I would warn you from doing it after beers though.

Vag com it is very important
mmarcski: taking out the throttle body help you to do a really good job if not you gonna push the dirty grime inside your intake... and buying the VAG-COM it is the best investment you can do if want to work in your car.
