Hello Peter! The was an upgrade for the ECM for your year and model car. Look on the inside of the gas door, there should be a sticker that says RE92. If not the ECM and wiring will need to be upgraded and modified. Only a Volvo dealer or a Volvo specialist will be able to repair it. If the RE92 sticker is there, you will have to have it fault traced by a technician for a proper diagnosis.
