If you are having problems with your recirculation or cut off valve or getting an error code pertaining to it this article will show you how to change it out. It is not a difficult job and there are only really two things you need to concern yourself with. One is that you are working on the turbo itself which can hold a lot of heat, so make sure it is cool when you start to work. Second, these cars are famous for the amount of blow by oil, be prepared for a surprising amount of oil to come out of the down pipe.

You may be able to remove the valve without removing the down pipe but there is not a lot of room to work to begin with; removing the pipe only takes a few minutes and frees up a lot of much need space.

Remove the rubber connection from the down pipe to intercooler by pulling out the quick release clip on the down pipe (red arrow) and separating the pipe from the hose.
