hello friends my car pug 307 2007 model 1.6 hdi so there is a can-bus brain system on make-up case as far as I researched from the forum, I decided to get my car to have a speed control lever smoothly. the vehicle sees the speed control arm but does not operate, the problem is not there, we stopped giving the speed control arm, but the busefer did not work, the computer of the key did not work whatever they did not tried to introduce the key, did not try from the computer, that is, the brain tried again, did not last did not try a new key again did not last but we could not do this to the authorized service they said go, I wonder what the problem might be
