    03 Passat VCDS light cant change engine adaptations but limmiwinks and other programs

    will.

    I was trying to change the idle in my car in the channel 01 adaptation of the engine. I got it to work with limmiwinks no problem and I went back into VCDS to verify but does anyone know why it wouldnt work in VCDS? When I put in a test value it would say error in the new box. Also if i Pushed the up value to increase it from 128 to 129 it would almost instantly say error.

    I was able to change other adaptations no problem though.

    Lemmiwinks doesn't change adapation channels via the diagnostic API. It does so via direct memory writes which bypass all the value checks in the normal API.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.
