Hi after some help please. 08 octy 1.9 tdi 80k, been fine all week, sat idle yesterday. So went to go out today, turned key and dash lights flickering, battery I thought? No car fired first time but cut out after about 1-2 seconds then started beeping at me? Three times this happened.

Saturday so obviously nowhere open, be greatfull for some pointers before Monday.

Usually if the car beeps flat battery , it beeps because the alarm senses the drop in voltage so thinks its being broken into 

Thanks for the reply, it was the dash beeping not the horn. Left car for few hours and it started fine with no flickering of dash lights, although airbag light on permanently now?
