	1.8T ME7.5 AGR OFF « on: November 26, 2024, 06:37:08 AM »

Hello, I feel pretty stupid but I've been searching for hours and still can't find solution to completely disable egr system and keep fuel trims working. In original file CDAGR, CLAAGRF, CLAAGRE are 0 so I dont seem to understand logic of working. Can someone help either by telling which switches (or what maps)should I change to disable egr system completely. Attached ori bin from skoda 4x4.

Do not change any CL* variables.
You need to remove DTC's without touching them, then you will not have problems with fuel trims.

there is no egr in this ecu / engine

probably you want to disable SAI system (CDSLS)

Yep you are right, there is no egr in this car. Because I havent seen the car and the owner said there is egr but he mistakes it with the SAI. Thank you very much, I know how to disable sai.

Never mind, I misread your post, I thought you set CDAGR, CLAAGRF, CLAAGRE to 0.
If it is like that in original file, then it has no EGR from factory.
