The canooter valve is a part of the exhaust regeneration assembly on new diesel engines. The canooter valve usually fails due to overheating of the exhaust bearings.

It's spelled "Canuter" not canooter. Over use of this valve is caused by faulty friggate switch wiring. When this happens, the muffler bearings become hot and can seize.

Eventually, the catalytic converter fluid will become tainted with halogen bulb fluid due to canuter valve blow-by.

At this point, it's best to scrap the vehicle..
