What problem did you have with your catalytic converter?
My car smokes on hard acceleration occasionally and I've been getting a CEL for EGT's when regenning lately. I figured it was just a problem with the DPF or EGR, but I'm curious about problems with the Cat.
I, too, would just delete everything, but I already have the Kerma tune, and my impression was that they are not ones to support the deletion of emissions related devices.
I'll preface this with the note that most of my driving is 70-80mph highway.
I was returning from a 6 hour round trip and the DPF light came on.
The next morning I went to refuel and put it in sport mode and drove aggressively, but that didn't clear the light.
I went into the dealership the next day (now with a CEL as well) and the tech had the car for about 3 hours, driving and pulling codes. He said that it wasn't the DPF but the CAT...
The symptoms I was running into was about 30mpg and the aux fan? kicking on after about 3 minutes of driving. The car stayed at a constant 190 degrees, but after parking, you could feel the heat emanating from the engine bay and under the car.
There wasn't a noticeable decrease in power.
I still haven't got an ETA on the part yet...
