To whom it may concern,
We would like to send you additional comment for this PQR as below.
At this moment, it is not necessary for the you to call back the customer again and conduct additional inspections, because the vehicle is working properly now.
But if the vehicle faced on exactly same failure (same Error code occurrence) in the future again, you must inspect the condition of Boost Pressure Sensor, Common Rail System (including Pressure Sensor of the Common Rail), by following the Shop Manual.
Error Code occurrence does not always mean internal failure of the pointed component.
It sometimes happen when the connecting situation of related connector have poor connection or dirty terminals.
