[mjozsa]

Hi All

My name is Mate (Roamania, Cluj) and I have a Fiat Stilo 1.2 from 2002. From 5 weeks it is in garage, without a final diagnostic.

1. It is possible to be a CAN failure.
2. It is possible to be the failure of body computer.

in the opinion of Fiat service...
This is the origin of my question.

I appreciate your help!
