Description<\/strong><\/h2>\n

The 24 pcs diesel injector return flow meter adapter kit is the ideal professional technical tool for BMW enthusiasts wishing to accurately diagnose common-rail diesel injection systems. Designed to enable simultaneous leak-off measurement on up to 6 injectors, the kit is ideal for BMW 4-cylinder engines. and<\/em> 6-cylinder diesel.<\/p>\n

BMW engine compatibility (representative examples)<\/strong><\/h3>\n

4-cylinder diesel common-rail<\/em> :<\/p>\n

    \n
  • M47 engine (BMW 1 series, 3 series, 4 series 2.0 d)<\/li>\n
  • \n

    N47 engine (BMW 1 serie, 3 serie, 4 serie 2.0 d): 4-cylinder diesel engine from 2007-2014.<\/p>\n<\/li>\n

  • \n

    B47 engine (BMW 4-cylinder diesel from 2014 to today).<\/p>\n<\/li>\n<\/ul>\n

    6-cylinder diesel common-rail<\/em> :<\/p>\n

      \n
    • \n

      M57 engine (BMW 6-cyl diesel classic, 1998-2013).<\/p>\n<\/li>\n

    • \n

      N57 engine (BMW 6 cyl diesel, 2008-2018).<\/p>\n<\/li>\n

    • \n

      B57 engine (newer BMW 6-cyl diesel, since 2015).<\/p>\n<\/li>\n<\/ul>\n

      If your BMW diesel is equipped with one of these engines (e.g. Series 1, Series 3, Series 4 with 4-cylinder diesel; Series 5, Series 7, X3, X5 with 6-cylinder diesel), this kit is perfectly suited to your needs.<\/p>\n

      Functionality and benefits<\/strong><\/h3>\n
        \n
      • \n

        Simultaneous measurement of up to 6 injectors: particularly useful for BMW 6-cylinder engines, but also useful for 4-cylinder engines by connecting just 4 cups.<\/p>\n<\/li>\n

      • \n

        Each graduated cup measures the amount of fuel returned by the injector over a given period. This reveals a worn, blocked or faulty injector before serious symptoms appear (loss of power, smoke, excessive consumption).<\/p>\n<\/li>\n

      • \n

        Included: 24 adapters covering a wide range of common-rail injectors (Bosch, Delphi, Siemens...), maximizing compatibility even beyond BMW.<\/p>\n<\/li>\n

      • \n

        Robust construction: ~70 cm pipes, aluminium bar with hooks for under-hood mounting, storage case. For workshop or garage use.<\/p>\n<\/li>\n

      • \n

        Time-saving and precise: you can make a reliable diagnosis without having to dismantle all the injectors or intervene blindly.<\/p>\n<\/li>\n<\/ul>\n

        Application tips for BMW<\/strong><\/h3>\n
          \n
        1. \n

          Park the BMW on a level surface, with the engine warm but switched off, and take all safety precautions (pressurized diesel, fuel return).<\/p>\n<\/li>\n

        2. \n

          Locate the injector return hoses (4 or 6 depending on engine). Disconnect them.<\/p>\n<\/li>\n

        3. \n

          Choose the right adapter kit for your injector type (Bosch\/Delphi\/Siemens).<\/p>\n<\/li>\n

        4. \n

          Connect each tube to a measuring cup. Attach the aluminum bar under the hood to hold the beakers in place.<\/p>\n<\/li>\n

        5. \n

          Start the motor for a set time or follow a test protocol.<\/p>\n<\/li>\n

        6. \n

          Compare the volumes measured for each injector: large discrepancies (e.g. > 15-20 %) indicate a potentially faulty injector.<\/p>\n<\/li>\n

        7. \n

          Take action (cleaning, adjustment, replacement) if necessary.<\/p>\n<\/li>\n

        8. \n

          Replace the original pipes, check for leaks, then store the kit in its case.<\/p>\n<\/li>\n<\/ol>\n

          Technical specifications<\/strong><\/h3>\n
            \n
          • \n

            Contents: 6 measuring beakers + 6 measuring cups + 6 tubes (~70 cm) + 24 adapters + aluminium bar + case.<\/p>\n<\/li>\n

          • \n

            Materials: ABS + stainless steel (high-strength adapters).<\/p>\n<\/li>\n

          • \n

            Application: leak-off measurement for common-rail injectors.<\/p>\n<\/li>\n

          • \n

            Compatible with: 4 or 6-cylinder common-rail diesel engines (BMW and others).<\/p>\n<\/li>\n
