I kept getting the same codes off and on for about 6 months. I went through 2 oxygen sensors and a maf on my own before I found a good mechanic who specializes in porsche. I don't like the dealer in my area. It turned out to be a vacuum leak. A $2 rubber part. After I parked in the garage I would get a very small amout of oil in the same spot. It was sucking air in through the hole and the oxygen sensors could not lean it out enough resulting in the codes for rich threshold.
