hello, this is my first post here in the forums. i own a shop and also do some mobile programing & diag. another shop contacted me and said he bought a used ecm for a 2000 audi a8. the immobilizer needs to be satisfied now. if i am understanding this correctly. i need to get the pin code and then can use vcds to enter. my question is, is the code stored only in cluster? or am i able to get out of ecm to with possibly a vag tacho? i have odis software and security through j2534 but i believe it only works from 2004 forward. any help is appreciated.
