Went to Halfords (approx 1.5 mile away) and got them to check battery,engine not warmed up and showing just 1bar lit on temp gauge , battery showed less than 12.5 volts, and 570 start power from 760 , official battery is AGM096 (less than (£200) at Halfords, Phoned Audi at Wakefield to confirm battery but all they would tell me is the official battery is £316 and it has 390 amps, gone onto eBay and even on there the proper batteries are over £300 ! Halfords did say the Battery was faulty so I suppose my next option is to speak to the RAC and explain the situation??
