THOM, I am sorry that I forgot to tell you to replace the dipstick o-ring,radiator cap, and oil fill o-ring and the gas cap. My previous owner had this done at the advice of the Porsche service manager in Carey, NC. (also because of the same cel's) Sorry. Max Go figure ???

Thanks i'll stop by the dealer and pick up the parts tonight. I'm surprised that the radiator cap might play a role here

Hello, I had the same symptoms with the same CEL codes and idle problem.

I cleaned the throttle body with alcohol and a cotton towel. It was a 30 minute job total.

Idle Problem Gone. I reset the CEL. It never came back on again. That was almost 1 year ago.

I put new o-rings on the oil dipstick and the filler cap. I had previously replaced the gas cap. It may be wishful thinking on my part, but the idle seems much steadier. Let's see if that holds up and if the CEL pops back on over the next few days. Great if it doesn't; less than $10 if it does.

Thanks to everyone who commented on my secondary air system problem.

I started the journey about a year ago chasing P0410 and P1411. $5K in parts and labor later, the the check engine light has remained dark after putting in a new vacuum reservoir.

Go figure!

the key problem my be a completely separate issue..


recently i parked teh car and hit the remote key to lock the car, on return, pressed the button to unlock and the key basically had a 'mind-fart' and wouldnt work.

spoke to my local porsche main stealer and they advised me that the old tye keys could lose their programming after a time and a newer version of key had been released. so porsche supplied a new key and programmed it to the car.

your key just may be on it's last legs a separate issue to the fault codes.
