Vauxhall Zafira add blue warning on when full

A low car battery is the most common cause of the s/s problem and MAY be tied in to your warning , especially if low usage and short journeys . Might be worth getting your battery tested and charged or replaced as needed . Or give car a good run .

some of the ad blue systems need to connected to diagnostic software, in order to tell the ecu that the tank has been refilled and to start the pump again....or the pump has siezed up and may need replacing....
