In this video, I show you the full process of replacing a fuel injector on a 2011 Nissan Qashqai J10 1.5 dCi diesel. If your Qashqai is suffering from rough idle, injector fault codes, excessive smoke, poor acceleration, diesel knocking, difficult starting, or an injector leak, this video will help you understand what is involved in removing and replacing a diesel fuel injector on the 1.5 dCi K9K engine. I take you through the process step by step, including: 🔧 Removing the engine cover and accessing the injectors 🔧 Identifying the correct injector/cylinder 🔧 Disconnecting the injector electrical connector 🔧 Removing the diesel leak-off/return pipe 🔧 Removing the high-pressure fuel pipe 🔧 Removing the injector retaining clamp 🔧 Extracting the old injector 🔧 Removing the old copper injector washer 🔧 Cleaning the injector bore and injector seat 🔧 Installing the new copper sealing washer 🔧 Installing the replacement injector 🔧 Refitting the high-pressure fuel line 🔧 Reconnecting the injector return line 🔧 Priming the diesel fuel system 🔧 Coding the replacement injector to the ECU 🔧 Starting the engine and checking for diesel leaks 🔧 Clearing fault codes and checking injector performance ⚠️ IMPORTANT: Common-rail diesel fuel systems operate at extremely high pressure.

If you are not confident carrying out this repair, use a qualified mechanic. Also remember that injector specifications can vary between different versions of the Nissan/Renault 1.5 dCi K9K engine, so always confirm your engine code, injector part number and correct torque specifications before carrying out the repair.
