Last weekend we had the oil changed on this car. The "service due" light will not go off. I stopped by a German car repair shop we have used before and the man looked it up on a computer disk. The instructions said to press the 0 on the left hand side of the dash and hold it while turning the key to the second position(when the dash lights up). I have tried this several times with no luck. Help! I need to turn this message off. Thanks in advance!!
