BMW 3 Series (E90/E91) Diesel Injectors

About BMW 3 Series diesel injectors

The BMW 3 Series is Britain's most-sold premium diesel saloon and the volume model behind nearly every "BMW injector" search in the UK. Across the E46, E90, F30 and G20 generations, the 3 Series has used three injector families: the older Bosch CRI 1.x on the M47 (320d / 318d, 1999-2007), the high-volume Bosch CRI 2.x on the N47 (2007-2014) and the piezo Bosch CRI 3.x on the B47 (2014 onwards). Every remanufactured 3 Series injector we ship is recalibrated against a Bosch master rig, packed with a new copper sealing washer, the IMA classification code printed on the test certificate, and a 12-month warranty. Because we hold all three generations in stock from our UK warehouse, your replacement is despatched the same day if you order before 2 pm. Whether you're fitting one cylinder after a misfire fault code or refreshing the full set on a 130k-mile build, the parts arrive ready to torque-down and code.

Common injector faults on the BMW 3 Series

  • N47 timing chain stretch causing injector seat damage and cylinder 1/4 misfires
  • B47 piezo stack drift on long-life cabs and high-motorway-mileage examples
  • M47 nozzle erosion on early 320d / 318d engines past 120,000 miles
  • Copper-washer leak-down ("black death" equivalent) on N47 after a botched re-fit

Why choose remanufactured?

A new OEM BMW injector lists at £400-£550 each — four cylinders is a £2,000 bill on a 10-year-old car. Remanufactured units restore identical performance and warranty for a fraction of that. Every reman injector ships with a printed Bosch EPS 815 test sheet so you (or your fitter) can verify flow and leak-off before installation.
