regardless of what change he made in the original file, the car starts and stops

virtual read auto works properly on the original file

[Le-Mans]

The changes on your file is not correct

[kuki88]

can you make a file for me with one error disabled so that I can confirm it

Three people made the files for me, and each of them had the same problem.

Solved

The problem was caused by a short circuit in the flowmeter wires
about 20 cm to the block entering the flow meter
I just don't know why the car didn't report a problem on the original file
on the modified file it went out.

The harness is repaired, adblue and egr are turned off and the car drives like new.

Thanks.
