I'm having real trouble starting my Astra (hot or cold) it's as if the battery is low (but I know its not, its been charged) I have just noticed that (what I believe is the imobilser light) flashes when I have the ignition on. Is this normal? :?:
If I start the car when the head lights are on, all the lights dim as if the battery was low.
Its the first Vauxhall I have ever owned and I'm not familiar with any of it.
