Title: ME17.5 lambda error after swap Post by: arved on July 29, 2023, 02:48:59 AM 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 Title: Re: ME17.5 lambda error after swap Post by: gremlin on July 29, 2023, 07:52:15 AM its possible that is a difference between the hardware of both ecu? 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.

Ok, so whats your sugestion? get a AB ecu? or its possible to modify my AA one?
