Hi everyone, I got problem with my Audi A6 C7 2011 2.0L diesel this is component lock. If i need to change anything need to unlock first without that i can't do anything. Which cheap software i can use and we went to Europe last in april and i got problem with airbag light on dash mechanic changed fuse and light gone. when we came back after few month same thing again i went to mechanic he can't remove after i called airbag and seat belt specialist he said ECU problem. After changing ECU with coding he done same problem. I called ECU specialist in Guildford he checked and told me car is component lock and some one messed it my ECU he add function in car what i don't have and now need to reset to factory and then add again what function we have. Any advise on this??? Thanks Gunit

As far as I know an Audi dealer needs to unlock the component protection you have.
