I have a combination of P0068 and P307A errors - MAF/MAP error together with Air Flow Too Low on my Audi 3.2 liter DI engine. The suspicion on the internets is plugged snow screen and/or dirty throttle body. So I will be checking the snow screen and clean the throttle body.
I am wondering, why would the throttle body get dirty? The pictures of the dirty throttle body show gunked up with carbon or caked oil. I thought the exhaust gasses were introduced to the air flow way after the throttle body.
