Hi, i have swapped a 2.5 2010 jetta from automatic to manual transmission.
the oem ecu was a 07k906055AA, the cruise control, esp and many things don't work with the auto ecu, so a flashed with odis a manual transmission file, 07k906055AC
now every thing its working, but i get a lambda heather error, short to ground. its possible that is a difference between the hardware of both ecu?
i'm not a ecu file expert, but its possible to change the AC file lambda part with the AA lambda part for it works?

thanks a lot

May be. We can say that at least the ECUs have different hardware numbers.
For SW ...055AA HW# ...055AA is used
For SW ...055AC HW# ...055AB is used
In addition, AC software complies with Euro3/Tier standard, while AA software complies with Euro5 standard.

IMHO manual SW version for 055AA HW doesn't exist among original factory files.

try disable lambda diagnosis, setting CDLSH, CDLS... etc to 0.
