  1. Ok, I've posted before about the 0420 cel code. Most say it's the secondary or the cat itself. What no one would have guessed was dealer sabotage. At one time I only maintained the car at the dealer, always the same dealer, a few years ago I caught the dealer trying to pull a fast one, they actually tried to patch the aos line they cracked during service with duct tape. They failed, I caught them, and I forced them to repair the damage they caused. Since then I've always maintained the car myself. So after I quit using the dealer, it was only a short time before the cel light came on and I started replacing parts. O2 sensors. Maf, and I was getting ready to do the secondary air system and the cats. 0420 was the dominant code, since I was playing with the car I decided to de snorkel and modify the air intake. De snorkeling was easy enough and per Pedro's I went to change the air intake to eliminate the additional muffler device. As I removed the air intake I noticed a finger sized glob of what looked like wheel bearing grease smeared inside the housing where the intake muffler deal is connected. Now, there's no way that glob of grease got there on its own, I didn't put it there, so all I can assume is those bastards at bluegrass Porsche are even more underhanded than first suspected. I removed the grease, cleaned the intake thoroughly , rest the codes and spent the day driving. I didn't fully alter the intake due to a additional line that runs to the plenum that isn't showed on Pedro's walk thru. I did eliminate the silly muffler and simply capped the opening, oddly enough a part from a drain valve from a Swiss medical device washer fit perfectly to cap the hole. The question, first, was the big glob of grease perhaps causing the wonky error code? And second, what is the line that runs from the intake to the plenum and can it be removed/ capped to fully alter the intake? Thanks boys...
