hi, would really appreciate some help if anyone can. My daughters Audi A3 has been unused for 2 months apart from being started occasionally. We went to start it on Sunday and the dash was completely dead. Air con radio indicators etc all ok. Car is turning over and will occasionally start but the immobiliser cuts in, so won't run. Battery is ok horn works. Hubby has checked fuses and all seem ok. Has anyone else had this happen to them?
