⚠️ Common Signs of Failure

• Black or white smoke and poor throttle response
• Hard starting, especially when hot
• Rising fuel consumption or diesel finding its way into the engine oil
• Fault code logged against a single cylinder

🛠️ Service Notes

• Class matters: only class 2 and class 3 are available as spares, and the listing states they can be used alongside the remaining classes already on the engine — check the class marking on your injectors and ask us if you are unsure
• The production window is 2000 week 34 to 2011 week 51, so confirm your engine's build date before ordering
• Renew the injector seals and copper washer, torque to the manual figure, and expect the injector trim or calibration code to need entering afterwards
