I've just had an issue with my CS, it had a misfire/judder and the engine warning light came on, I couldn't stop immediately so carried on the road, slowed down and looked for a safe place to stop, the car juddered and the light continued to flash, then the light went out and the warning disappeared. After investigation by Porsche Aberdeen, where at 1st they found a solenoid wrong with the vario-cam, they found that the CAT on the r/h side of the engine was melted. I did have a Milltek 200 cell full system fitted, after they re-fitted the original system they now say the misfire is no longer. I find it hard to believe, I did get the engine log print out and it shows 14 misfires on cylinder 3 after it was in the workshop. What I want to know is if anyone has had a misfire issue and if so has it been resolved properly by Porsche? I wonder if the misfire came 1st, thereby flooding unburnt fuel in the CAT, then the unburnt fuel ignites it burns the CAT out as the tempature is way above the normal operating range of the CATS.
I'm putting this in the Cayman roadster forum as well, they have similar/the same engines and better to spread any word and get more feedback, maybe.
