d13 egr valve

Might make it. As long as computer doesn't want a regen. Then you may get derates severe enough to screw up your plans.

 

prob is that there is almost no egr valve availability from oem so you might get more time off than u planned for till they get one in.

 

Hmm, I had one fail on a 2006 Mercedes engine. It was stuck closed. Don't know if this would work for you depending on what is wrong with yours.
I cleaned out the carbon, greased the pivots on mine. Got another two months out of it.

 

as long as its stuck closed you'll be fine.. it may do a 50hp derate

 

This abnormal egr flow code ,not sure bad egr valve, mostly caused bad diferential presure sensor , harness water condensation inside venturi , or plugged venturi /egr cooler.
I would start with the sensor , easy to remove clean check the connector, dont lose the rubber gaskets.
