First, please use English - most people won't bother replying if they have to read through the "dat"s and "da"s to decipher what you're trying to say.

Second, have you scanned for codes? That's the first step in finding an issue on these cars.

Third, when does this happen? When the car is cold? Hot? After a long drive? During stop and go traffic? When it's warm or cold outside? Need more info on the circumstances - some systems work at particular engine operating and/or environmental parameters and not during others.
