Up date on issue took a look at it and belt was off, puzzled really if belt was off how is I could drive car with message on dash, so refitted belt and the message as gone so I tested the battery (engine off) was reading 11.35 (engine on) reading 14.56 so took it for drive tonight no message back and belt still on strange, but still have a loss of power in car but this just may be down to the intercooler pipe as I may have a split in it some where as engine makes a whistling sound when accelerating would I be right there
