Genuine BMW & MINI Diesel 2700 Bar Fuel Rail/Injection Pressure Sensor Upgrade | Common Rail Transducer/Sender | OEM Direct-Fit | Replaces 2200 Bar (M18) | Fits B37 B47 N47 N57 | 320d 120d 125d 328d

BMW and MINI Diesel Rail Pressure Transducer Upgrade – 2,700 bar Range

Push your diesel build further with this factory BMW rail pressure transducer that reads up to 2,700 bar. It stops saturation where the standard 2,200 bar sender tops out, so your mapper can target and control higher injection pressures with confidence on B37, B47, N47 and N57 platforms. Perfect for remapped cars, hybrid turbo setups and vehicles with an uprated high-pressure fuel pump where accurate data is essential for smooth, reliable fuelling.

It is a direct swap on the listed applications, retaining OEM reliability and plug-in connectors. No rail machining is required in standard fitments, making it a clean, professional solution for serious diesel tuning on BMW and MINI.

Key reasons to choose this 2,700 bar rail sender

• Extends measurable pressure range to 2,700 bar for high-demand diesel mapping
• Eliminates signal clipping beyond the stock 2,200 bar limit
• Gives your tuner finer control for consistent torque delivery and clean combustion
• Genuine BMW part for factory fit, durability and compatibility
• Plug-and-play replacement on supported rails, ideal for performance builds

Important fitment note

Do not install without calibration. ECU scaling is required. Fitting this sensor without appropriate remap can cause engine damage.

This upgrade is intended for vehicles originally supplied with the 2,200 bar sender. Your tuner must update sensor linearisation and diagnostics to suit the 2,700 bar unit.

Thread information

Sensor thread is M18. If your rail currently uses an M12 threaded sensor with a removable insert, the insert can be taken out to accept this M18 unit.

Proven on tuned BMW and MINI diesels

We have fitted and calibrated this sensor across multiple in-house projects. Feedback from our customers has been excellent, with stable rail control under heavy load, stronger high-gear performance and cleaner logging at elevated pressure targets when combined with quality software.

Installation and calibration

• Direct swap on supported rails
• No rail modification required for standard applications
• ECU rescaling essential for correct operation
• Professional installation recommended
