This issue will almost certainly cause internal engine damage if it fails in an open state, which is common. The condition it causes inside the engine is an improper lean fuel mixture. Some engines are more prone to damage from this, because some manifolds distribute the egr gas more evenly than others. Typically you will wind up with a burnt valve on one cylinder which will cause a constant miss and costly repairs.
This has happened to me on two suzuki engines on cylinder that is closest to the egr, and one small block v8 Chevrolet on number 8 next to the egr.
Fix it asap or lose your engine.
