Range Rover Non-OEM Calibration Fix Tool

Range Rover Non-OEM Calibration Fix Tool – Safely Remove Non-OEM Maps & DTC P167F-00 (V6 & V8 MED17.8.31)

The Safe, Professional Way to Remove Non-OEM Maps & DTC P167F-00 from MED17.8.31 ECUs
​Modern Range Rover engines are masterpieces of engineering — especially the V6 & V8 platforms running Bosch MED17.8.31 ECUs. But there’s a growing problem across workshops, tuning garages, and even official dealer networks:
Non-OEM calibration detected.
And it doesn’t go away easily.

Whether someone previously tuned the ECU, flashed a modified file, or attempted a stock restoration that wasn’t 100% perfect — the ECU can detect it instantly and throw a fault code:

DTC P167F-00 – Non-OEM Calibration Detected
This code isn't just annoying. It causes:

• Diagnostic failures
• Warranty issues
• Dealer flags
• Blocked module programming
• Failed emissions checks
• Reduced trust during resale

And until now, the fix wasn't simple.
But that just changed — in a BIG way.
