Coalsmoke, the P2262 code is an indication that the turbo is plugging up. It needs to be cleaned by the dealer (under warranty) and I don't know if they still replace them if that fails? I do have a straight pipe with a o2 sensor bung that is part of the H & S kit. It does replace both the cat and dpf. As far as the question regarding once you delete the Egr valve how does the turbo stay clean? Well, you now are pushing clean air through the intake, and not by-passing it through the Egr valve and re-gen system. In addition, you need to disconnect the 3/4" pcv line that goes into the front of the turbo. I simply capped the end of the 3/4" nipple on the rubber boot that attaches to the front of the turbo, and replaced the 3/4" hose with a longer one coming from the egr valve and tucked it to dump along the fender well. Why they designed these turbos to be kitchen garbage disposals is beyond me. You might as well not have an air filter. What pluggs these turbos is all the soot from the recycling of it through the intake, through the Egr valve, re-generation process and the backing up of the cat and dpf. These turbos are variable vane and when they get too much soot the vanes can't operate and slide properly. Once the deletes are done you should not have anymore problems with these turbos as clean air coming in is then burned with the fuel and exited directly through the exhaust side of the turbo through a straight flowing exhaust pipe.
