By | February 28, 2023

Problem:

It’s boot mode read file and I tried to write VAG Simos 18.1 with OBD using foxflash software.

Tried with 13.5v and without external power. Tried with original and mod file.

What this error mean?
(Error Patch File)
Foxflash Error Patch File Simos 18.1

Solution:

You cannot write a boot file via obd, simos 18,1 obd is calibration area only file in obd. Users need to understand that the OBD VR file for simos 18.1 is a special file that contains only calibration data.

Open ECU and read it in boot mode.
