B47 injectors require coding via BMW ISTA using the 8-digit calibration code on each injector body. Unlike N47, the B47 is more tolerant of single injector replacement, but we still recommend inspecting all four during service. Use OEM copper washers and torque to 8Nm.
The BMW B47 engine requires injectors calibrated to specific flow rates and spray patterns. At Remanufactured Injector, our technicians test every B47 injector to original manufacturer specifications using OEM-grade diagnostic equipment.
BMW B47 Injector Cost
BMW B47 diesel injector replacement cost UK ranges from £150 to £400 per injector for remanufactured units. The B47 engine uses precision-calibrated injectors that require exact flow rates and spray patterns.
Testing B47 injectors costs £20 each and confirms which specific injector is causing problems. Common B47 symptoms like rough idle, black smoke, or poor fuel economy often stem from just one faulty injector.
Our remanufactured B47 injectors are tested to BMW original specifications with new seals, nozzles, and 12-month warranty included. Same performance as new, significantly lower cost.

Common Problems with BMW B47 Injectors
The BMW B47 engine commonly experiences injector issues related to solenoid coil degradation causing slow response times, nozzle erosion from high injection pressures, and connector corrosion in vehicles exposed to road salt. Regular fuel filter changes extend B47 injector lifespan significantly. Professional testing identifies exactly which injector is failing before expensive replacements.
Symptoms of Failing BMW B47 Injectors
Failing BMW B47 injectors typically cause: rough idle or vibration at standstill, excessive white or black smoke on startup, poor acceleration and "limp mode" activation, increased fuel consumption (10-20% worse), engine warning light with P0201-P0204 fault codes, hard starting especially when cold, and diesel knock or rattling sounds. Early diagnosis prevents secondary damage to turbochargers, DPF systems, and cylinder walls. If you notice any of these symptoms, professional injector testing (£20/injector) can confirm the diagnosis before committing to replacement.
