2.5 audi quattro kess problem and stage one needed - SERNAS2 - 28-10-2018
i'm trying my kess device. Just bought audi a4 2.5tdi quattro manual AKE engine.
I was trying to read id, ecu and error of unknown ecu appeared, then proceeded and ended up with sw read error.
so then i decided to play with different ecus from the list, and when i chose bosch edc15vm+ rather then bosch edc15vm+2 i received error of unknown ecu, but after i proceeded kess readed ecu. As far as i know pump was changed at some point on this vehicle, can it be that different power output pump was fitted, so kess can't read it when choosing ake engine from the list?
the details i managed to extract:
HW: 0281010823
SW: 1037351928
VIN nr.:
SW ver.: 28SA5486
Spare:
Engine: 2.5L V6 TDI AG
HW Ver.:
SW upg.: 8E0907401D 0006
could somebody look into this, and maybe tune it to stage 1? Will it be safe to write it back?
