Why it happens

Likely root causes behind P1496

Carbon and soot cake the EGR valve plate, shaft and valve seat.
Condensation and oil mist form acidic sludge after the EGR cooler.
Motor gearbox wears from continuous modulation and high resistance.
Coolant leakage through the cooler or valve interface corrodes electronics and accelerates sludge build-up.
Position sensor drift causes commanded-versus-actual mismatch.
Soot caking on valve seat and butterfly plate.
Diaphragm or seal hardening after heat cycles.
Actuator motor fails prematurely when the valve is stiff from deposits.
