Jaguar E Pace Diesel Running Rough: Reset Drift Fix

Had similar symptoms on my 2014 Jaguar XF Diesel at around 120000km. The rough engine running combined with fuel injection issues pointed to faulty injectors. The onboard diagnostics initially showed drift compensation errors, which often indicates injector problems. The repair required specialized equipment to properly diagnose and fix the injection system. Basic system resets did not resolve the issue. The car sensors detected incorrect fuel delivery patterns, requiring complete injector replacement on two cylinders. The repair process involved: Full diagnostic scan, Injector removal and testing, Replacement of defective injectors, Performance tuning to calibrate new injectors, Reset of fuel injection parameters This was a serious repair requiring specialized knowledge. Regular mechanics often lack the specific diagnostic tools needed for modern diesel injection systems. The job took about 2 full days at a specialized diesel workshop. Post-repair, the engine returned to smooth operation, check engine light cleared, and fuel efficiency improved notably. These symptoms should not be ignored as faulty injectors can cause additional engine damage if left unattended.

Thanks for sharing those details about the injector repair. Your experience matches what happened with my E Pace. After the repair, the onboard diagnostics showed everything was back to normal and fuel economy improved significantly. Just curious, do you remember the final cost of your repair? Also, have you experienced any other injection-related issues since the fix? My performance tuning values are still holding steady after 6 months, but I keep a close eye on the engine behavior since that incident.

Thanks for asking about the repair outcome. Really glad to report that since getting the injection valve fixed at the specialist workshop, the Reset quantity drift compensation issue has been completely resolved. The total cost came to 515€ for replacing the defective injector and completing the necessary performance tuning adjustments. The fuel economy improved dramatically once the fuel injection system was properly calibrated. Since the repair 18 months ago, all system diagnostics have remained stable with no recurring issues. The original rough running completely disappeared after the fix. For monitoring purposes, I regularly check the onboard diagnostics and fuel consumption patterns. The engine maintains consistent performance without any drift in the injection parameters. Having the system reset done by qualified technicians really made the difference in getting the repair done right the first time. The repair cost was significant but prevented potential long-term engine damage. Proper fuel injection calibration is crucial for these modern diesel engines to maintain optimal performance and efficiency.

Thanks for your input. After dealing with this issue, I wanted to share how my repair experience went. Took the car to a specialized diesel workshop after my research. The compensation adjustment process revealed two damaged injectors needing replacement. Workshop time was about 3 days total, with the final bill reaching 1250€ including parts and labor. The fuel injection system works perfectly now. After the system reset and performance tuning, my E Pace runs smoother than ever. Fuel consumption dropped by about 1.5 liters per 100km. Quick tip from my experience, the workshop provided a detailed diagnostic report showing all reset procedures and calibration values. Worth asking for this documentation when getting similar work done. No issues in the 6 months since the repair. Regular diagnostic checks show all parameters staying within spec. Definitely worth paying for proper specialist repair rather than trying quick fixes at a general workshop.
