I have an 07 300c, took old Bty out and put new Bty in, the following day, the wipers,indicators,front windows,mirrors do not work also on dash ABS, ESP, BAS, all stay lit with the engine running everything working fine before the battery change ( the car had been stood for approx 4 weeks before the bty change) I took it for a short run, Its a stunning looking car but I am quite clueless.
