Audi A6 C5 key matching problem

[barth71]

Hi everyone
I have a problem because i try key matching to this car but someone tried to add a key before and something is wrong.
I read pin through OBD an PIN is 01701 and try login to cluster but VCDS say , "not correct" . A diagnosis vcds also say " fail comunicate " when i try read fault code. I read 93c86 from cluster and PIN from 93c86 is correct 01701.
Please help me repair dump from this cluster or you will tell me another solution.
Thank you

Ok maybe you are right. I did not think about it ;-(. I will connect the dash on on bench and leave it on power for longer. Thank you for your info. But you check is my PIN is correct? 01701 ?
