Q: Do I need calibration or coding after install?
A: Generally no coding required. Follow OEM depressurise/prime procedure, then verify commanded vs actual rail pressure with a scan tool and clear any DTCs.

A: Hard starting, rough idle, throttle hesitation, surging, limp mode, poor fuel economy, or rail-pressure deviation codes (P0087/P0088) are common signs.

Q: Can I install this myself?
A: Yes — it's a straightforward replacement if you're comfortable with basic diesel fuel system work. Follow proper fuel system depressurisation procedure and torque specifications.
Q: How long does an SCV typically last?
