Help in diagnosing smog failure '17 S3

[sjdennis]

Hi All,
I'm trying to advise my niece on what to do about her car. 2017 Audi S3 81k miles. The car just failed its California emissions test for the following reasons.

"Monitors are incomplete" Tech suggests 200 mile drive with 12 warmup cycles
Catalyst Monitor not ready
Oxygen Sensor not ready

"Vehicle has permanent codes in memory"
P0107 - Manifold Absolute Pressure Sensor Circuit Low
P0113 - Intake Air Temperature Sensor I Circuit High Bank 1

Using the Google tech it seems the P0107 could be as simple as a gas cap. The P0113 could be a faulty MAF sensor. Both of these don't seem that serious and could be relatively inexpensive to fix. And the "not ready" monitors might reset after driving as the Tech suggested. I'm telling her not to panic at this point, but I'm not that familiar with Audi's. Reaching out to see what you all have to offer as advice.

Thanks so much in advance for your help!

So first off a primer on Permanent codes. Permanent codes are a new thing in 2010 and newer cars. By themselves they are not an indication that there is a current problem. They are a carbon copy of a "Confirmed" code that turns on your Check Engine Light. So what this means at one time the car had a Confirmed code for those 2 codes and the confirmed code was cleared (with a scanner or Battery Disconnect) and what's left over is Permanent codes. Those permanent codes alone with the 2 monitors being incomplete indicated to me someone recently cleared codes on this car. Now the question is why did they do that?

Know of any recent repairs? New battery? recent service?

So with only a Permanent code and no Check Engine light there is nothing to repair until a Confirmed code comes back and a check Engine light comes on.

The 200 miles and 12 warms ups is a reference to a CA SMOG rule that says Permanent codes will be ignored when you have driven 200 miles and have 15 warm up cycles since the last time codes were cleared. I assume at the time of the smog she had 3 warm ups. So your smog tech is hoping those 2 monitors will complete as well in those 200 miles driven. And that's a good strategy to follow and then see what happens in those 200 miles.

Now the strategy to get those 2 monitors complete in those 200 miles is to follow the drive cycle. The drive cycle is a set of driving instructions to give the ECU the correct conditions to run it's tests. See what you can find online or in this forum, sure someone posted it over the years.
