There is a difference on proffering technical help to allow someone to repair a broken vehicle and advice to remove a component which renders the vehicle illegal on the road and damaging to health. How your Cummins diesel behaves is not relevant to the needs of Volvo D5 owners and has no bearing on the guys technical needs. I'm merely saying that while it was once a common solution to EGR problems to throw out the unit altogether, the moral compass on this issue has changed and the legislation with it, regardless on how well an old Cummins engine might work.
