Hi,The restrictor hose will be the one with the white stripe on it. It is the only white striped hose on the EGR circuit. Once removed you will be able to feel the restrictor inside the hose as well, about half way through. The restrictor is a silver ball about the size of a BB with a tiny orifice drilled through it.To test if it is the problem, just replace the hose with a standard non-restrictor hose temporarily and see if you no longer get the insufficient flow fault. If the fault goes away, the restrictor was the issue. Just looking through it is not sufficient, as you can see light through it and have it still be too clogged to prevent the flow fault from occurring.
