🔌 Function

The kit transmits exhaust pressure to the differential-pressure sensor, allowing the control system to detect restriction and monitor aftertreatment performance.

⚠️ Common Signs of Failure

• SCR differential-pressure fault codes
• Hoses are heat-damaged, split or blocked
• Condensation or soot blocks the pressure line
• Sensor readings are implausible or unstable
• Exhaust leakage is visible around the fittings

🛠️ Service Notes

• Service kits are built for a specific engine family and serial-number range, and contents change between builds — confirm the kit against your engine's serial number before ordering
• Check the kit against the job before you start and fit it complete; leaving out the parts that still look serviceable defeats the point of a kit
• Renew every gasket, seal and O-ring supplied even where the old ones appear sound, and follow the tightening sequences and figures in the workshop manual for your engine
• Record the work and the engine hours when the kit goes in, so the next service falls due at the interval Volvo Penta specifies for your engine
