Audi a4 Electronic issue
 

I have an issue with my Audi a4, i put my key in the ignition , and the hazard
warning lights come on , the car starts and then fades away as if it gone into
lock down, this does not do it all the time, did it friday and then okay saturday and sunday, but played up again today, has anyone have an idea on whats causing this, and the only way to stop the hazard warning lights is to take off the battery lead , can someone please help me.

Many thanks

Mike
