Hi everyone, I`m pretty new to these topics but i learn fast and i enjoy trying technical stuff.
We drive a VW T4 and a Ford Focus 2005 TDCI. For a friends similar T4 i removed the immo after a ECU Change. I did this by desoldering the 24c04 and changing the dump by immokiller (for sure resoldering afterwards).

For VAG Im now interested how to perform this action by OBD and if its possible to remove the agr (Abgasrückführung ~ exhaus-gas reflow?)

For the Ford Im looking for a possibility to deactivate the immo or learn a new key. (Since 3 years we share the single existing key in the family) Since Ford wants 140€ I rather spend this for a good tool and do it by myself.
