Thanks, any idea where I can get a new battery also? I'm assuming the halfords one aren't good quality or maybe they don't work on BMWs?

I just bought a battery for my '06 E60 in Halfords last week - not a Halfords branded one (Yuasa). Not sure if they sell the AGM batteries for cars that have stop/start function
