After about 6 days and maybe 200mi the check engine light came on. I took it to AutoZone and used their computer and got CEL PO492,secondary air system, insufficient flow. I called the dealer and he said to take it to a local repair shop and get an estimate for repair and call them. I got a wild hair and thought I would try a different computer at O'Riely auto and when the guy checked it he said, "oh that's nothing, see it all the time" and reset the CEL. Now, a hundred mi later still no CEL!! What to do!! It is a bit different for me as I live in a very small town with no Porsche dealer. The car is for my girlfriend who lives in a larger town,(Columbia, Mo.) but still no Porsche dealer. 100mi from St. Louis which is where I bought the car. The dealer will repair free of charge problems for up to 30 days. I hate to take it to a foreign car repair shop in Columbia, Mo and tell them this story and leave them a car with no CEL on. Thoughts?

Repeating codes are not based on miles they are based on a number of cycles that the system runs and are checked by the ECU. Cycles are based on run time, either minutes or hours depending on the system and component that failed. Secondary air system codes are hair pullers to figure out unless someone who understands the Porsche diagnostic tree and has correct diagnostic equipment. A year ago I pulled a CEL that was caused by two secondary air system codes that has been diagnosed as the failure of two diaphragms in the secondary air system. Because I didn't need to have my car smogged I put off repairing them until this year. The car has been running fine with no other issues than fewer mpg which is caused by the vacuum leak in one, or both diaphragms, that will cause the ECU to add more fuel to the mixture. The repairs are not cheap so it is a good thing the dealer you bought it from will repair it under warranty.
