A neighbor came over last weekend to look at my Porschesince he is an x owner and a supposed aficionado.. He told me the easiest fixin 996s is to replace the air filter. Iwent to the Porsche Dealer this week bought one. My neighbor came over lastnight, popped the hood and put it in the car. Only problem was that he said “giveit a start” and did not put the cover on the Air filter. The car made a loud Warbling noise and I shutit down after 5 seconds. Now my checkEngine light is on and according to my Neighbors ODB Device I show warninglights for codes # PO410 AND P1411

Does anyone know what the problem could be?

Never run your car without the air filter.

Those fault codes are for your secondary air pump (used for emissions).

You need to make sure that it is plugged in as well as anything else that you might have un-plugged to change the air filer (like the MAF).

Search is your friend...http://www.renntech.org/forums/index.php/topic/6885-cel-error-codes-p0410-and-p1411/

My guess--running the engine with the air box disconnected caused the secondary air pump function to not register properly. Suggestion: completely reinstall the air box, clear the codes (disconnect battery for 10 minutes...make sure you have your radio code handy!), then drive the car. If the CEL doesn't re-light, you're good to go.

Good luck
