FAQ

Q: What symptoms if EGR valve sticks open?
A: Excessive exhaust gas recirculation causes lean mixture, rough idle, poor power, black smoke and easy stall at low temperature.

Q: Can I block the EGR pipe to disable it?
A: Not recommended. It triggers emission fault code and torque derating, the engine may not work normally.

Q: The EGR valve looks clean, why circuit fault is logged?
A: Internal drive motor or position sensor can fail without visible signs. Judge by diagnostic data stream.

Q: Will carbon cleaning make EGR valve reliable for long term?
A: Only works for light carbon deposit. If valve plate is worn or motor degraded, cleaning is temporary and failure will recur.
