A4 8K, CJCD engine (150 hp), currently at 180,000 km.

Injector 1:
- Common rail pressure calibration point: -5.14 µs.
- Common rail pressure calibration point: 2 -4.80 µs.
- Common rail pressure calibration point: 3 -7.10 µs.

Injector 2:
- Common rail pressure calibration point: -14.10 µs.
- Common rail pressure calibration point: -3.65 µs.
- Common rail pressure calibration point: -1.10 µs.

Injector 3:
- Common rail pressure calibration point: -16.35 µs
- Common rail pressure calibration point: -2.00 µs.
- Common rail pressure calibration point: 3 -8.35 µs.

Injector 4:
- Common rail pressure calibration point 1: 12.25 µs
- Common rail pressure calibration point: -18.85 µs.
- Common rail pressure calibration point: -16.30 µs.


Comparison values are available in my posts from August 2016 (48,000 km) and January 2020 (115,000 km). Some significantly negative values have decreased, and injector 4 is moving towards positive values with calibration point 1. Otherwise, no anomalies detected.

The A6 seems to have quite a bit of carbon buildup, but it's not showing any obvious symptoms. I've owned the car for several years and regularly monitor its values. I've tried using additives at times, but they haven't made much of a difference...

It would be great if I could get feedback on the values and development process, if possible.

Hello everyone, Here are the values for my Octavia 5E5 4x4 CKFC. Series 150 hp / 320 Nm, chip tuning to 181 hp / 398 Nm, 191,000 km mileage. Experiences occasional slight jerking in the partial load range below 1500 rpm. Unfortunately, mostly used for short trips up to 15 km. Currently noticeable: the injector correction value for cylinder 4 is unusually high during idle and partial load conditions. This one ranges from 0.57mg to 0.73mg, while the others range from -0.1mg to -0.3mg. Rail pressure calibration times 1/2/3 in µs.

Note: Cylinder 2, calibration point 2 at 250,350 km is most likely a sign error, but I can no longer find the original data for it.
