What exactly does P0401 mean?
P0401 means the ECU measured less EGR gas flow than it commanded. The ECU expects a specific intake MAP pressure drop when it opens the EGR valve — if the drop doesn't happen (because the valve is stuck, the cooler is blocked, or the DPFE sensor is faulty), it sets P0401. GarageNation's OEM data logging identifies exactly which component is causing the insufficient flow.
Is P0401 a serious fault code?
P0401 means your car is emitting more NOx than permitted — illegal for emissions compliance, even if driveability is unaffected. It will cause PUC failure. Most P0401 cases at GarageNation are resolved by EGR cleaning at ₹3,500–₹12,000. If the valve mechanism is damaged, replacement is ₹8,000–₹28,000.
Is p0401 egr flow fault fix covered by car insurance in India?
Standard comprehensive motor insurance covers p0401 egr flow fault fix only if the damage was caused by an accident or a specified peril (fire, flood). Mechanical failure from wear is not covered.
