Help with a3 please
Hey everyone. Hoping someone can help. I have a 2015 Audi A3 2.0T Quattro. My check engine light came on and now when my car is at idle ( park neutral or drive ). The RPMs are jumping up and down. I too car to autozone and had them check the codes. A couple codes came up and I will try to attach pic. My initial thought was the MAF sensor needs to be cleaned or replaced. There is 70k miles. So I went to go find maf off of the intake line and I can’t locate it at all. Does this car have an maf or map? And where is it located at. I can not find it anywhere. Also what are everyone’s thoughts on the problem ? Thank you in advance for everyone’s help !

Looks like leak in the intake tract. Could be crack in the manifold, or one of the fittings. Maf should be behind the airbox on the way to the turbo. One trick if you are handy, but not good at diagnosis, is take it to a good independent shop and pay to have it figured out, and have them show you then do the work yourself if its an easier fix.

It looks like your dip stick went bad. Dip sticks can get shriveled up and ineffective with old age. But don't worry, it's a common problem and it happens to a lot of guys.
I would recommend a short throw dip stick for weight savings. Might as well get a pack of 5 at Autozone while your there.
In all seriousness it could be a vacuum leak. I would search google for 'PCV valve a3' if it were me

Looks like there's something wrong obviously within the airflow system... somewhere between the air box and maybe the turbo or throttle body. take it to a shop or just check for a leak
