Hello

i have this tiguan auto gerbox and keyless go system

problem is that ecu get water damage not readable, i even move MCU to a good ecu and when i power on ecu MCU get hot so trash

i buy same ecu for the car second hand ecu is ok i read with smok all immo related info from ecu and from dash of the car

transfer all immo data over OBD after this i do a login to dash (MAC is leaned in this way) all ok

car start 2 times and after no more ignition ON

on diag all ok no immo related DTC in engine ecu or ELV or DASH

if i do a log in in DASH ignition can be switched on but i have immo related error in engine ECU

where is the problem?

i notice that second part of the MAC from ecu is written in the dash and i think MAC is stored in KESSY ecu to or am i wrong?

this can be the problem that MAC do not match in DASh and kessy -> and no more ignition

why elv do not lock when car is locked from remote?


i put a second hand elv same behavior and replace kessy ecu to and same behavior

no error in kessy ecu or elv or dash

and engine start without pressing brake pedal
