Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
Do you still have the factory exhaust manifolds with pre-cats on the car or did you replace those with aftermarket headers?

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1Original post

So guys you know a couple weeks ago I installed the APE exhaust in the Cayman S. Before I installed it I had the check engine light on so I took the car to the dealer here in Puerto Rico. They told me it was an O2 sensor so they changed it unde warranty. The thing is on my way back home the light came on again. Do I need a software upgrade to fix this or is it the O2 sensor again ? Anyone with this same problem ? Thanks, Ricky

Then you need to have your codes read out (you can do so with an OBDII code reader from most auto parts stores or a sears store) and then see what those codes are. If you didn't touch the factory exhaust manifolds then no you don't need to reprogram your ECU or anything you need to find out what the problem is and get it fixed under warranty if possible, a catback exhaust system won't trip a cel (check engine light) because it comes after the manifolds with the O2 sensors. Without knowing your error code stored by the ECU we have no way of knowing what the problem is, heck your gas cap being loose would cause a code...
