GLC 250CDI EDC17CP57 P20F5 Error

[Dee89]

Hi Guys,

im getting trouble after writing mod file for edc17cp57 MB GLC250CDI.
DTC shows P20F5, telling me reductant consumption too high. However, Adblue maps were not touched,
so cant explain the error. Perhaps some of you Guys encountered the same issue and can guide me how to solve this issue.
Engine runs fine and has no Limp Mode active. Ori and mod file are attached for you.
Thank you
