exhaust filter cleaning comes up on dash from time to time but cant find any reference to it in hand book also do I need to use adblue in this vehicle not used to oil burners especially these new high tech high performance ones and info would be grand  having issues with the brakes think they are wearing thin but doesnt appear to have a warning lamp they are seemingly acoustic ??? what the hell is that!!!!
