My sport is make a constant grinding noise while running, and grinds a few seconds when it is shut off. I have the Eco Tune and my CEL does not work any ways, of course this is the wives vehicle and she does not know what an EGR valve is and how useless it is. Any way to make it stop, or will it go away on its own?

It is not your EGR, but it could be the intake throttle. These have plastic gears inside and will make a grinding noise if it fails. Try unplugging the wiring to the throttle and see if the noise disappears.

Wow, that is a first, a diesel throttle? Is it the valve that cuts off the intake on shut down? Is it part of the EGR? I will give it a try, thanks.

The Intake Throttle is what Chrysler Jeep call it on the Parts Fiche. It is more commonly known as a Flow Control Valve.

Yes and Yes

My Wife's TDI has a throttle plate to provide suction to suck in the exhaust from the EGR.

I wonder if removing the butterfly plate, removing the plastic gears, Let the motor run so the ECM is happy, and plating off the EGR inlet would get rid of the noise?

Some of the old '50s IDI diesels like MB and some IH tractors like the early B275D had a throttle, Vinturi, and a diaphragm that looked like a small brake booster. Vacuum on the booster from the engine sucking against the diaphragm would slow down the engine. Open up the throttle, the inline pump rack would go full bore until the suction in the venturi moved the rack to reduce fuel. Nissan had this system on their Diesel Pickups for a few years, I think Joe Romas had one and may be able to tell you more. I remember these type of diesels were not as responsive as our CRDs to say the least.

On my TDI I took the EGR and the throttle plate assembly off and replaced it with a diesel geek race pipe, I then twisted the MAF sensor until all parameters in VAG matched and got no more CEL.

You may not be able to read or see some of the pics here, the members of the TDI forum are Uber sensitive to outsiders.
