Technical Problem with engine dynamics, evaluation of CSV file

[Piotr129]

Hi everyone,
I’m having performance issues with my Ducato 2.3L 150 HP. The van has 45,000 km on the clock. I bought it with 8,000 km and have owned it for 3 years.
Since the beginning, I’ve felt that while driving at a constant speed, the engine occasionally loses and regains power (surging) on its own. It has improved over time, but it’s still noticeable. Recently, I replaced the MAP sensor. Surprisingly, the power surging decreased, but the engine's responsiveness at low throttle also dropped. I have never had any fault codes (DTCs).
I’ve started analyzing engine parameters via MultiEcuscan (MES). I noticed that when the engine is cold, the LP-EGR (Low Pressure EGR) remains open while driving. I’m not sure if this is normal, but after a few minutes of driving, it starts working within its expected range.
I know there are many experts here, and I would really appreciate your help. I’m attaching the log file from my recent short test drive."

Hi @Piotr129 I tried my best but I only understand one language - English. Some parameters I could understand by the values, but it became to difficult for me. Perhaps if you could change the language to English in settings ( I suspect you are multilingual - I am not unfortunately) before recording a file to upload?

Sorry, I didn't think of that. I updated the description, hope it works now!"
Tomorrow, I'll take template number 7 for another drive

I really cannot see any issue from the parameters chosen in the attached CSV file. Perhaps try running the Templates as suggested here: https://www.fiatforum.com/guides/re...ines-for-blocking-lpegr-cooler-diagnosis.991/
